The length (width) of the protrusion 81 in the direction along the X-axis is substantially equal to the length (width) of the first protrusion wall 74 in the direction along the X-axis.

As shown in FIG. 4, the two second protruding walls 75 and the two third protruding walls 76 extend in the direction along the Y axis across the opening forming portion 91 and the object inclined portion 92. That is, the second protruding wall 75 and the third protruding wall 76 are provided in the opening forming portion 91 and in the object inclined portion 92.

The third protruding wall 76 extends from one end (first end 71c) of the upper surface 71b in the direction along the Y axis to the other end (second end 71d). In the direction along the Y-axis, the length of the first protruding wall 74 is shorter than the length of the second protruding wall 75 and shorter than the length of the third protruding wall 76.

As shown in FIG. 7, the two protrusions 77 project downward from both ends of the lower surface 71a of the plate portion 71 in the direction along the X axis, and are separated from each other in the direction along the X axis. In other words, the two protrusions 77 project from the third end 71e and the fourth end 71f. Therefore, the first protruding wall 74 and the two second protruding walls 75 project from the upper surface 71b at a position different from the two protrusions 77 in the direction along the X axis.

The plate portion 71 further has a continuous region 95. The continuous region 95 is a region where the lower surface 71a is continuous in the direction along the X axis between the third end portion 71e and the fourth end portion 71f. The continuous region 95 extends linearly in the direction along the X-axis and is substantially flat. In FIG. 7, the continuous region 95 is shown schematically surrounded by an alternate long and short dash line.

The two protrusions 77 project from the continuous region 95. In other words, the two protrusions 77 are arranged at positions different from the discontinuous region of the lower surface 71a, avoiding the discontinuous region in the direction along the X axis.

The protrusion 77 is located between the first mounting portion 72 and the second mounting portion 73 in the direction along the Y axis. The two protrusions 77 are arranged at overlapping (overlapping) positions in the direction along the Y axis. According to another expression, the two protrusions 77 are arranged at overlapping positions when viewed from the direction along the X axis.

In the direction along the Y-axis, the distance between the protrusion 77 and the first mounting portion 72 is shorter than the distance between the protrusion 77 and the second mounting portion 73. The positions of the two protrusions 77 are not limited to the positions described above, and may be other positions. For example, the two protrusions 77 may be arranged at different positions in the direction along the Y axis.

In the direction along the X-axis, the length (width) of the protrusion 77 is shorter than the length (width) of the plate portion 71. In the direction along the Y axis, the length of the protrusion 77 is shorter than the length of the plate portion 71. The length (thickness) of the protrusion 77 is shorter than the length (thickness) of the plate portion 71 in the direction along the Z axis. In other words, the length between the lower surface 71a and the tip of the protrusion 77 in the direction along the Z axis is shorter than the length between the lower surface 71a and the upper surface 71b of the plate portion 71. The length of the protrusion 77 is not limited to this example.

The first foreign matter interfering member 25 is attached to the lower rail 21 as described below, for example. The method of attaching the first foreign matter interfering member 25 is not limited to the following procedure and operation.

As shown in FIG. 6, the bottom wall 31 of the lower rail 21 is provided with a first mounting hole 101, a second mounting hole 102, a first insertion hole 103, and a second insertion hole 104. The first mounting hole 101 may also be referred to as a first hole or hole. The second mounting hole 102 may also be referred to as a second hole. Further, the bottom wall 31 has a first inner peripheral surface 101a forming the first mounting hole 101 and a second inner peripheral surface 102a forming the second mounting hole 102.

The first mounting hole 101, the second mounting hole 102, the first insertion hole 103, and the second insertion hole 104 each penetrate the bottom wall 31 in the direction along the Z axis and the bottom surface 31a of the bottom wall 31. And a hole having a circular cross section that opens on the inner surface 31b. The first mounting hole 101, the second mounting hole 102, the first insertion hole 103, and the second insertion hole 104 may have other shapes.

The second mounting hole 102 is provided at a position separated from the first mounting hole 101 in the direction along the Y axis. The first insertion hole 103 and the second insertion hole 104 are located between the first mounting hole 101 and the second mounting hole 102 in the direction along the Y axis.

FIG. 9 is a perspective view showing a first foreign matter interfering member 25 of the first embodiment and a part of the lower rail 21 on which the second mounting portion 73 is hooked. As shown in FIG. 9, first, the second mounting portion 73 is inserted into the second mounting hole 102 with the lower surface 71a of the plate portion 71 facing the inner surface 31b of the bottom wall 31. The second mounting hole 102 has a size that allows the second mounting portion 73 to pass through.

As shown in FIG. 6, when the second mounting portion 73 is inserted into the second mounting hole 102, the protruding portion 85 of the second mounting portion 73 is passed through the second mounting hole 102. When the protrusion 85 comes into contact with the second inner peripheral surface 102a of the second mounting hole 102, the movement of the first foreign matter interfering member 25 in the forward direction is restricted.

The claw 86 is arranged downward from the bottom wall 31, and the locking surface 86a faces the bottom surface 31a of the bottom wall 31. In other words, the claw 86 is hooked on the bottom wall 31. Therefore, the bottom wall 31 is arranged between the lower surface 71a of the plate portion 71 and the locking surface 86a, and the movement of the first foreign matter interfering member 25 in the direction along the Z axis is restricted.

FIG. 10 is a perspective view showing a first foreign matter interfering member 25 of the first embodiment and a part of the lower rail 21 into which the first mounting portion 72 is fitted. Next, as shown in FIG. 10, the first mounting portion 72 is inserted into the first mounting hole 101 in a state where the second mounting portion 73 is hooked on the bottom wall 31.

For example, by rotating the plate portion 71 so as to approach the bottom wall 31 with the contact portion between the second mounting portion 73 and the second inner peripheral surface 102a as a substantially center, the first mounting portion 72 becomes the first. Approach the mounting hole 101 of 1. Further, the protrusion 77 comes into contact with the bottom wall 31. When the protrusion 77 abuts on the bottom wall 31, the first locking surface 83c of the first mounting portion 72 is located above the bottom surface 31a. In this case, the first foreign matter interfering member 25 is not attached to the bottom wall 31 and can be removed from the bottom wall 31.

Next, as shown in FIG. 6, the plate portion 71 is elastically deformed so that the first end portion 71c is brought closer to the bottom wall 31. By elastically deforming the plate portion 71, the first mounting portion 72 is inserted into the first mounting hole 101 with elastic deformation of the plurality of claws 83. That is, the first mounting hole 101 has a size that allows the first mounting portion 72 to pass through by elastically deforming the plurality of claws 83 so as to approach the protruding portion 81. The maximum outer diameter of the first mounting portion 72 is larger than the maximum outer diameter of the first mounting hole 101 in a state where the plurality of claws 83 are not elastically deformed so as to approach the protruding portion 81.

When the first mounting portion 72 is inserted into the first mounting hole 101, the protruding portion 81 of the first mounting portion 72 is passed through the first mounting hole 101, and the elastically deformed claw 83 is restored. The base 82 and a part of the claw 83 are arranged downward from the bottom surface 31a.

As shown in FIG. 8, the first locking surface 83c of the restored claw 83 faces the bottom surface 31a of the bottom wall 31. In other words, the claw 83 is hooked on the bottom wall 31. Therefore, the bottom wall 31 is arranged between the lower surface 71a of the plate portion 71 and the first locking surface 83c of the claw 83, and the first foreign matter interfering member 25 is restricted from moving in the direction along the Z axis. Will be done. As a result, the first foreign matter interfering member 25 is attached to the bottom wall 31.

Further, the second locking surface 83d of the plurality of claws 83 faces the first inner peripheral surface 101a of the bottom wall 31. This limits the movement of the first foreign matter interfering member 25 in the direction along the inner surface 31b of the bottom wall 31.

For example, the claw 83 may be kept in an elastically deformed state, and the second locking surface 83d may be pressed against the first inner peripheral surface 101a by the restoring force of the claw 83. As a result, the first foreign matter interfering member 25 is more strongly fixed to the bottom wall 31.

As shown in FIG. 6, the protrusion 77 abuts on the inner surface 31b of the bottom wall 31 to keep the plate portion 71 in an elastically deformed state. The plate portion 71 elastically deformed with the contact portion between the protrusion 77 and the bottom wall 31 as a fulcrum presses the first locking surface 83c of the first mounting portion 72 against the bottom surface 31a of the bottom wall 31 by the restoring force. The locking surface 86a of the second mounting portion 73 is pressed against the bottom surface 31a. As a result, the first foreign matter interfering member 25 is more strongly fixed to the bottom wall 31.

In the direction along the Z axis, the length L of the protrusion 77 is the length of the bottom wall 31 from the distance C1 between the lower surface 71a of the plate portion 71 and the first locking surface 83c of the first mounting portion 72. (Thickness) equal to or longer than the length obtained by subtracting T (L ≧ C1-T). Further, in the direction along the Z axis, the length L of the protrusion 77 is the length (thickness) T of the bottom wall 31 from the distance C2 between the lower surface 71a and the locking surface 86a of the second mounting portion 73. Is equal to or longer than the subtracted length (L ≧ C2-T). As a result, the plate portion 71 is elastically deformed as described above, and the first locking surface 83c and the locking surface 86a are pressed against the bottom surface 31a of the bottom wall 31. The length L of the protrusion 77 is not limited to this example.

For example, at the first end 71c and the second end 71d, a part of the lower surface 71a comes into contact with the inner surface 31b of the bottom wall 31. The continuous region 95 is a region in which the lower surface 71a, which is the surface closest to the bottom wall 31 of the lower rail 21, extends in the direction along the X axis. If the first mounting portion 72, the second mounting portion 73, and the protrusion 77 come into contact with the bottom wall 31, the lower surface 71a may be separated from the bottom wall 31.

When the first foreign matter interfering member 25 is attached to the bottom wall 31, the first opening 78 of the plate portion 71 and the first insertion hole 103 of the bottom wall 31 overlap and communicate with each other. Therefore, a member such as the rivet 105 can pass through the first opening 78 and the first insertion hole 103 from above. The rivet 105 is, for example, a pop rivet in which the bottom wall 31 and the first foreign matter interfering member 25 are attached to the floor 1a in FIG.

The second opening 79 and the second insertion hole 104 overlap and communicate with each other. Therefore, a member such as the reference pin 106 can pass through the second opening 79 and the second insertion hole 104 from below. The reference pin 106 positions the first foreign matter interfering member 25, for example, when measuring the dimensions of the first foreign matter interfering member 25 and the lower rail 21, or when assembling the slide rail device 11. This facilitates the assembly of the slide rail device 11. The first opening 78 and the second opening 79 are not limited to these examples.

As shown in FIG. 3, foreign matter (objects) 120A and 120B may enter the inside of the lower rail 21 through the gap between the two inner side walls 34. The foreign objects 120A and 120B shown in FIG. 3 are, for example, lighters dropped by the passenger of the vehicle 1. The foreign matter 120A and 120B are not limited to this example.

For example, the foreign matter 120A interferes with the first protruding wall 74. Therefore, the foreign matter 120A is supported in an upright or inclined state by the first protruding wall 74. In the example of FIG. 3, the foreign matter 120A is supported not only by the first protruding wall 74 but also by the second protruding wall 75 and the inner side wall 34 of the lower rail 21.

Further, the foreign matter 120B interferes with the third protruding wall 76. The gap between the tip (upper end) of the third protruding wall 76 and the tip (lower end) of the inner side wall 34 of the lower rail 21 is smaller than the thickness of the foreign matter 120B which is a lighter. Therefore, the third protruding wall 76 limits foreign matter 120B from entering the gap between the third protruding wall 76 and the inner wall 34. The foreign matter 120B is supported in an inclined state by the third protruding wall 76 and the two inner side walls 34.

The foreign substances 120A and 120B supported in an upright or inclined state are arranged at positions overlapping with the upper rail 22 in the direction along the Z axis. Therefore, the upper rail 22 can be slid forward to push the foreign matter 120A and 120B forward. By being pushed by the upper rail 22, the foreign matter 120A and 120B are discharged from the inside of the lower rail 21 to the outside.

As described above, the first protruding wall 74, the second protruding wall 75, and the third protruding wall 76 extend parallel to the direction along the Y axis and are separated from each other in the direction along the X axis. Therefore, the foreign matter 120A and 120B pushed forward are prevented from being caught by the first protruding wall 74, the second protruding wall 75, and the third protruding wall 76, and the foreign matter 120A and 120B are inside the lower rail 21. Easily discharged from.

FIG. 11 is a perspective view showing a second foreign matter interfering member 26 of the first embodiment. FIG. 12 is a perspective view showing the second foreign matter interfering member 26 of the first embodiment from a direction different from that of FIG. The second foreign matter interfering member 26 is made of synthetic resin. The second foreign matter interfering member 26 may be made of another material.

The second foreign matter interference member 26 also has a plate portion 71, a first mounting portion 72, a second mounting portion 73, a first protruding wall 74, and a protrusion 77. The plate portion 71, the first mounting portion 72, the second mounting portion 73, the first protruding wall 74, and the protrusion 77 of the second foreign matter interfering member 26 are integrally formed, but for example, a plurality of members. May be formed by.

In the second foreign matter interfering member 26, the first end portion 71c of the plate portion 71 is the end portion of the plate portion 71 in the front direction. The second end portion 71d is the end portion of the plate portion 71 in the rear direction.

In the second foreign matter interfering member 26, the first protruding wall 74 extends from the first end 71c to the second end 71d across the first opening 78 and the second opening 79. In other words, the first protruding wall 74 covers the first opening 78 and the second opening 79 from above. Therefore, the second foreign matter interfering member 26 does not have the opening forming portion 91 of the first foreign matter interfering member 25. The second foreign matter interference member 26 may have an opening forming portion 91.

The first protruding wall 74 is provided with a first notch 74c and a second notch 74d. The first notch 74c communicates with the first opening 78. The second notch 74d communicates with the second opening 79. By providing the first notch 74c and the second notch 74d, it is possible to prevent the first protruding wall 74 from coming into contact with the member inserted through the first opening 78 or the second opening 79. ..

The length (height) of the first protruding wall 74 of the second foreign matter interfering member 26 in the direction along the Z axis is the length (height) of the first protruding wall 74 of the first foreign matter interfering member 25. ) Longer than. Therefore, the first notch 74c and the second notch 74d can be easily provided on the first protruding wall 74.

As shown in FIG. 12, the second foreign matter interfering member 26 has one protrusion 77 unlike the first foreign matter interfering member 25. The protrusion 77 of the second foreign matter interfering member 26 also protrudes from the continuous region 95. The protrusion 77 extends in the direction along the X axis between the third end 71e and the fourth end 71f, which are both ends of the lower surface 71a in the direction along the X axis. In other words, the protrusion 77 extends so as to cross the plate portion 71.

As shown in FIG. 11, the second foreign matter interfering member 26 further includes a first inclined portion 111 and a second inclined portion 112. The first inclined portion 111 and the second inclined portion 112 project from the upper surface 71b of the plate portion 71.

The first inclined portion 111 is provided from the portion where the first opening 78 is provided to the second end portion 71d of the plate portion 71. The first inclined portion 111 is inclined so as to be separated from the upper surface 71b toward the rear direction.

The second inclined portion 112 is located forward with respect to the first opening 78 and is adjacent to the first opening 78. The second inclined portion 112 is inclined so as to be separated from the upper surface 71b toward the rear direction.

The second foreign matter interference member 26 is attached to the bottom wall 31 by the first attachment portion 72 and the second attachment portion 73, similarly to the first foreign matter interference member 25. Then, the first protruding wall 74 supports a foreign object such as a lighter in an upright or inclined state. Therefore, when the upper rail 22 is slid backward, the upper rail 22 or the cap 23 pushes the foreign matter backward and discharges the foreign matter from the inside of the lower rail 21 to the outside.

The foreign matter pushed by the upper rail 22 or the cap 23 rides on the first inclined portion 111 and the second inclined portion 112. As a result, even if a member such as a rivet protrudes upward from the first opening 78, foreign matter is prevented from interfering with the member.

In the slide rail device 11 according to the first embodiment described above, the protrusion 77 is located between the first mounting portion 72 and the second mounting portion 73 in the direction along the Y axis, and the bottom wall 31. The plate portion 71 is elastically deformed so that the first mounting portion 72 and the second mounting portion 73 are pressed against the bottom wall 31 by abutting against. As a result, the first foreign matter interfering member 25 with respect to the bottom wall 31 while providing a gap between the bottom wall 31 used for elastic deformation of the first foreign matter interfering member 25 and the first foreign matter interfering member 25. Movement is suppressed. Therefore, rattling between the first foreign matter interfering member 25 and the bottom wall 31 is suppressed.

The protrusion 77 protrudes from the continuous region 95. The continuous region 95 is a region where the lower surface 71a is continuous in the direction along the X axis between the third end portion 71e and the fourth end portion 71f, and is less likely to be elastically deformed than the discontinuous region. For example, the upper rail 22 or the lock mechanism 24 may come into contact with the plate portion 71 or the first protruding wall 74, and the plate portion 71 may be pushed downward. In this case, since the plate portion 71 is not easily deformed around the protrusion 77, it is possible to prevent the protrusion 77 from changing the contact position between the bottom surface 31a of the lower rail 21. Therefore, even when the plate portion 71 is pushed, the protrusion 77 can continue to abut on the bottom wall 31 of the lower rail 21 at a desired position. By stabilizing the position where the protrusion 77 abuts on the bottom wall 31, rattling between the first foreign matter interfering member 25 and the bottom wall 31 is suppressed.

The two protrusions 77 project from the third end 71e and the fourth end 71f. As a result, the two protrusions 77 can stably abut on the bottom wall 31. Further, the plate portion 71 is stably supported by the two protrusions 77, and the weight increase of the first foreign matter interfering member 25 due to the provision of the protrusions 77 is suppressed.

The two protrusions 77 are arranged at overlapping positions in the direction along the Y axis when viewed from the direction along the X axis. As a result, it is possible to prevent the plate portion 71 from being elastically deformed so as to be twisted while the protrusion 77 is in contact with the bottom wall 31. Therefore, for example, a part of the first mounting portion 72 or the second mounting portion 73 may be undesirably separated from the bottom wall 31, or the position where the protrusion 77 abuts on the bottom wall 31 may be displaced. The occurrence of rattling between the foreign matter interference member 25 and the bottom wall 31 of 1 is suppressed. Further, the gap between the third protruding wall 76 and the inner side wall 34 undergoes an undesired change, and foreign matter 120A and 120B are suppressed from entering the gap.

The first foreign matter interfering member 25 has a first protruding wall 74 that protrudes from the upper surface 71b and extends in a direction along the Y axis. The first protruding wall 74 can support, for example, the foreign matter 120A that has entered the lower rail 21 in an upright or inclined state, and can help the upper rail 22 push the foreign matter 120A out of the lower rail 21. Therefore, foreign matter 120A is suppressed from entering between the upper rail 22 and the lower rail 21.

In the direction along the Y-axis, the distance between the protrusion 77 and the first mounting portion 72 is shorter than the distance between the protrusion 77 and the second mounting portion 73. Therefore, in a state where the protrusion 77 elastically deforms the plate portion 71, the force with which the first mounting portion 72 is pressed against the bottom wall 31 is stronger than the force with which the second mounting portion 73 is pressed against the bottom wall 31. Become. As a result, of the first mounting portion 72 and the second mounting portion 73, one of the first mounting portions 72 is pressed against the bottom wall 31 with a stronger force, and the first foreign matter interfering member 25 and the bottom wall 31 are pressed. It is possible to further suppress the occurrence of rattling. For example, as in the present embodiment, by providing the protrusion 77 at a position close to the first mounting portion 72 inserted into the first mounting hole 101 with elastic deformation, the first foreign matter interfering member 25 and the bottom are provided. It is possible to further suppress the occurrence of rattling with the wall 31.

In the direction along the Z axis, the distance C1 between the first locking surface 83c and the lower surface 71a is longer than the distance C2 between the locking surface 86a and the lower surface 71a. Therefore, the first locking surface 83c is more easily separated from the bottom surface 31a of the bottom wall 31 than the locking surface 86a. However, the protrusion 77 elastically deforms the plate portion 71, so that the first locking surface 83c is pressed against the bottom surface 31a with a strong force. Therefore, it is suppressed that the first locking surface 83c is separated from the bottom surface 31a, and the rattling between the first foreign matter interfering member 25 and the bottom wall 31 is further suppressed.

When the first mounting portion 72 is inserted into the first mounting hole 101, for example, due to the positional deviation of the first foreign matter interference member 25, the dimensional variation, and the position and dimensional deviation of the first mounting hole 101. , The first mounting portion 72 may come into contact with the bottom wall 31. Since the claw 83 extends from the base 82 toward the lower surface 71a, the base 82 is more likely to come into contact with the bottom wall 31 than the claw 83. The base 82 is less likely to be deformed than the elastically deformable claw 83. Therefore, it is possible to prevent the first mounting portion 72 from being damaged when the first mounting portion 72 comes into contact with the bottom wall 31. Further, the free end portion 83b of the claw 83 is located near the base end of the first mounting portion 72, and the connection end portion 83a of the base portion 82 and the claw 83 is located near the tip end of the first mounting portion 72. Therefore, the connecting end portion 83a of the claw 83 is more likely to come into contact with the bottom wall 31 than the free end portion 83b of the claw 83. Since the connecting end portion 83a of the claw 83 is less likely to be deformed than the free end portion 83b, it is possible to prevent the first mounting portion 72 from being damaged when the first mounting portion 72 comes into contact with the bottom wall 31. As described above, damage to the first foreign matter interfering member 25 at the time of mounting is suppressed.

The free end portion 83b of the claw 83 is located near the base end of the first mounting portion 72, and the connection end portion 83a of the base portion 82 and the claw 83 is located near the tip end of the first mounting portion 72. Therefore, when the slide rail device 11 is assembled in a state where the first foreign matter interfering member 25 is attached to the bottom wall 31, the connection end portion 83a of the base portion 82 or the claw 83 is more than the free end portion 83b of the claw 83. Is more likely to come into contact with other members such as the carpet of vehicle 1. Since the connection end portion 83a of the base portion 82 and the claw 83 is less likely to be deformed than the free end portion 83b, the claw 83 is suppressed from elastically deforming so that the first mounting portion 72 comes out of the first mounting hole 101. It is suppressed that the mounting portion 72 of 1 is undesirably detached from the bottom wall 31.

When the first mounting portion 72 is inserted into the first mounting hole 101, the claw 83 is elastically deformed in a direction approaching the protruding portion 81. When the claw 83 comes into contact with the protrusion 81, further elastic deformation of the claw 83 is restricted. This limits the maximum amount of elastic deformation of the claw 83 and prevents the claw 83 from being damaged.

The cross-sectional area of the base 82 that intersects the Z-axis is larger than the cross-sectional area of the protrusion 81 that intersects the Z-axis. Therefore, the base portion 82 is less likely to be deformed than the protruding portion 81. Therefore, when the base portion 82 collides with the bottom wall 31, the first mounting portion 72 is prevented from being damaged. That is, damage to the first foreign matter interfering member 25 at the time of mounting is suppressed.

The second mounting portion 73 is provided on the plate portion 71 at a position separated from the first mounting portion 72 in the direction along the Y axis, and the first foreign matter interfering member 25 is mounted on the bottom wall 31. As described above, since the first foreign matter interfering member 25 is attached to the bottom wall 31 by the first mounting portion 72 and the second mounting portion 73 at a plurality of separated positions along the Y axis, the first foreign matter is present. The interference member 25 is more reliably attached to the bottom wall 31.

The length of the protrusion 81 in the direction along the Y axis is longer than the length of the protrusion 81 in the direction along the X axis. Since the first foreign matter interfering member 25 is attached to the bottom wall 31 extending in the direction along the Y axis, it can be made to extend long in the direction along the Y axis as a whole. For example, due to such factors, when the first foreign matter interfering member 25 is attached to the bottom wall 31, the lower surface 71a is not completely horizontal to the bottom wall 31 and is tilted on the YZ plane. Sometimes. Further, as in the present embodiment, when the first foreign matter interfering member 25 inserts the first mounting portion 72 into the first mounting hole 101, the first mounting portion 73 and the second inner peripheral surface 102a It rotates on the YZ plane with the contact portion with the center as the center. At this time, the first mounting portion 72 inserted into the first mounting hole 101 may come into contact with the bottom wall 31. Further, for example, the claw 83 of the first mounting portion 72 abuts on the bottom wall 31 in the direction of exiting from the first mounting hole 101 due to the restoring force of the first foreign matter interfering member 25 elastically deformed by the protrusion 77. In these cases, a force on the YZ plane acts on the protrusion 81. However, since the length of the protruding portion 81 in the direction along the Y axis is long, the strength of the protruding portion 81 with respect to the force is improved, and damage to the first mounting portion 72 is suppressed. Further, since the strength of the protruding portion 81 is improved without making the protruding portion 81 thick as a whole, the cost of the first foreign matter interfering member 25 can be reduced.

At least three claws 83 extend radially from the base 82 and in a direction approaching the lower surface 71a. As a result, when the first mounting portion 72 is inserted into the first mounting hole 101, the connecting end portion 83a of one claw 83 extending in at least one direction can abut on the bottom wall 31, and the protruding portion 81. Is suppressed from coming into contact with the bottom wall 31. Therefore, damage to the first mounting portion 72 is suppressed. Further, when the first mounting portion 72 tries to move in the direction of exiting from the first mounting hole 101, one claw 83 extending in at least one direction can abut on the bottom wall 31. Therefore, it is suppressed that the first mounting portion 72 is undesirably detached from the bottom wall 31.

The first locking surface 83c of the claw 83 faces the bottom surface 31a, and the second locking surface 83d faces the first inner peripheral surface 101a. As a result, the first mounting portion 72 is prevented from coming out of the first mounting hole 101 in an undesired manner, and the first foreign matter interfering member 25 is oriented in the direction along the lower surface 71a with respect to the bottom wall 31. Movement is suppressed, and rattling between the first foreign matter interfering member 25 and the bottom wall 31 is suppressed.

The plurality of claws 83 elastically deformed when inserted into the first mounting hole 101 expand so that the second locking surface 83d approaches the first inner peripheral surface 101a due to the restoring force. Due to the restoring force, the claw 83 can press the second locking surface 83d against the first inner peripheral surface 101a. As a result, the movement of the first foreign matter interfering member 25 with respect to the bottom wall 31 in the direction along the lower surface 71a is suppressed, and the first foreign matter interfering member 25 and the bottom wall 31 may rattle. It is suppressed.

The first foreign matter interfering member 25 includes an opening forming portion 91 provided with a first opening 78 penetrating the first foreign matter interfering member 25, and an object inclined portion adjacent to the opening forming portion 91 in the direction along the Y axis. 92 and. The first protruding wall 74 is provided on the object inclined portion 92 and has a second end 74b in a direction along the Y axis. The second end 74b is located at one end of the object inclined portion 92 in the direction along the Y axis. Therefore, the first protruding wall 74 does not cover the first opening 78. Therefore, for example, a member such as the rivet 105 or the reference pin 106 can pass through the first opening 78 from the upper direction and the lower direction, and the slide rail device 11 can be easily assembled. Further, it is possible to prevent a tool or a robot arm that passes a member such as the rivet 105 from above through the first opening 78 from interfering with the first protruding wall 74. In addition, it is not necessary to provide the first protruding wall 74 with a notch for avoiding a member such as the rivet 105, and the first protruding wall 74 can be made smaller.

The second protruding wall 75 is provided in the opening forming portion 91, and is provided at a position different from that of the first opening 78 in the direction along the X axis. The second protruding wall 75 supports the foreign matter 120A, 120B that has entered the lower rail 21 in an upright or inclined state, for example, in the opening forming portion 91, and the upper rail 22 moves the foreign matter 120A, 120B out of the lower rail 21. Can help push out. Therefore, foreign matter 120A and 120B are suppressed from entering between the upper rail 22 and the lower rail 21.

The second protruding wall 75 extends in the direction along the Y axis across the opening forming portion 91 and the object inclined portion 92 without interruption at the boundary between the opening forming portion 91 and the object inclined portion 92. As a result, for example, foreign matter 120A and 120B are prevented from being caught between the first protruding wall 74 and the second protruding wall 75 in the direction along the Y axis. Further, in the object inclined portion 92, the first protruding wall 74 and the second protruding wall 75 can stably keep the foreign matter 120A and 120B in an upright or inclined posture.

The first opening 78 is located between the two second protruding walls 75 in the direction along the X axis. As a result, the state in which the first opening 78 penetrates the first foreign matter interfering member 25 is ensured without the second protruding wall 75 covering the first opening 78. Further, since the second protruding walls 75 are provided on both sides of the first opening 78 in the direction along the X axis, the foreign matters 120A and 120B that have entered the lower rail 21 by at least one of the second protruding walls 75 stand up or stand up. Can support an inclined state. Therefore, foreign matter 120A and 120B are suppressed from entering between the upper rail 22 and the lower rail 21.

The first protruding wall 74 is located between the two second protruding walls 75. In the direction along the Z axis, the length of the first protruding wall 74 is longer than the length of the second protruding wall 75. As a result, in the object inclined portion 92, the first protruding wall 74 reliably supports the foreign matter 120A, 120B that has entered the lower rail 21 in an upright or inclined state, and the upper rail 22 supports the foreign matter 120A, 120B in the lower rail 21. Can help push out from. Therefore, foreign matter 120A and 120B are suppressed from entering between the upper rail 22 and the lower rail 21.
