An outer plate portion 1A connected to the upper surface 2b and covering the displacement means 13 from the outside 4B is provided on the outside 4B side of the door opening 2. The arrow a indicates the rotation direction of the rotation shaft 5 and the lever 9 when the door body 3 moves toward the open position, and the arrow b indicates the rotation direction when the door body 3 moves toward the closed position. The rotation direction of the driving shaft 5 and the lever 9 is shown.
[0025]
The operation of the sealing device accompanying the opening and closing movement of the door body 3 will be described.
When the door body 3 is in the closed position, as shown in FIGS. 4 and 5, the other end 15 b of the rod 15 is moved toward the outside 4 </ b> B by the cover 35 provided on the lever 9 against the urging force of the coil spring 17. Since it is in the pushed state, the seal member 12 is located at the first position where the lower end 14d is located in the movement path Z and is in contact with the upper end 3e of the door body 3. In this state, when the rotating shaft 5 is rotated in the direction of arrow a by the driving means 8 shown in FIG. 1, the lever 9 also moves in the same direction, and the door body 3 closes the door opening 2 as shown in FIG. It rotates so as to cross in the vehicle direction B and moves toward one side edge 2 a of the door opening 2. When the lever 9 rotates in the direction of arrow a, as shown in FIGS. 6 and 7, there is no force to push the other end 15 b of the rod 15, and the rod 15 is supported toward the vehicle compartment 4 </ b> A by the urging force of the coil spring 17. It slides on the member 16. When the rod 15 moves to the compartment 4A, the lever 30 moves to the compartment 4A, and the shaft member 14 rotates clockwise in FIG. Due to the rotation of the shaft member 14, the seal member 12 placed at the first position also rotates in the same direction, and moves to the second position located above the upper end surface 3c of the door body 3.
[0026]
Therefore, even if the upper end surface 3c of the door body 3 moves and moves so as to cross the door opening 2, the seal member 12 and the upper end surface 3c do not come into contact with each other, and the seal member 12 is not squeezed by the upper end surface 3c. . For this reason, breakage of the seal member 12 is extremely reduced with the opening and closing operation of the door body 3, and the durability is improved, so that the sealability can be ensured for a long period of time.
[0027]
When the driving means 8 is driven to rotate the rotating shaft 5 in the direction of the arrow b, the lever 9 also rotates in the same direction, and comes into contact with the other end 15b of the rod 15 located within the rotating range during the rotation. . The rod 15 moves toward the outside 4B of the vehicle so as to compress the coil spring 17 with the rotation of the lever 9 in the direction of the arrow b. When the rod 15 is moved toward the outside 4B of the vehicle, the shaft member 14 is rotated counterclockwise in FIG. 7 via the lever 30, and the seal member 12 placed at the second position is moved by the movement of the lever 9. The rod 15 moves toward the first position shown in FIG.
[0028]
As described above, when the seal member 12 is provided on the displacement means 13, the first position where the upper end portion 3 e and the seal member 12 come into contact in conjunction with the operation of the lever 9, that is, the opening and closing operation of the door body 3, 3e can be moved to and from a second position retracted from the movement trajectory Z.
[0029]
【The invention's effect】
According to the present invention, the shielding member for shielding the gap between the upper end surface of the door main body and the upper surface of the door opening is in the first position in contact with the upper end of the door main body when the door main body is in the closed position by the displacement means. When the door body is opened and closed, the door body is located at the second position retracted from the movement trajectory of the upper end of the door body. Therefore, the door body does not interfere with the upper end of the door body during opening and closing movement, and damage to the shielding member is prevented. Thus, the durability of the member is improved, and the sealing property can be ensured for a long period of time.
[0030]
In particular, in the case of a glide slide door, since the upper end of the door body is opened and closed by positioning both sides thereof on the vehicle interior side and the inside of the vehicle such that the upper end of the door body crosses the shielding member, the shielding member of the door body is moved when the door is opened and closed. Placing it at the second position retracted from the movement track of the upper end portion is effective in preventing breakage of the shielding member because the upper end portion of the door body does not squeeze, improving durability and leading to long-term sealing performance. .
