  However, when the upper part of the boot is mounted on the ring-shaped bush, the inner surface and the outer surface of the boot are reversed and mounted on the bush, and after the mounting, the inner surface and the outer surface of the boot are reversed again to return to the original state. There is a problem that workability is not good because the work of reversing the boot is performed twice. There is also a problem in that the boots are likely to vary in the overall length after being attached to the bush.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a shift lever device capable of solving the above-described problems and mounting the upper part of the boot on the bush without inverting the boot.

The invention according to claim 1 is a shift lever in which a knob is provided at the upper end of the shift lever, a cylindrical bush is inserted into the lower side of the knob, and an upper end of a boot covering the shift lever is inserted into the bush. In the apparatus, a ring integrated part to which a ring is attached is provided in advance on the upper part of the boot, while a cylindrical member is integrally formed on the lower side of the knob, and a flange part having a larger diameter than the ring is provided in the bush. A ring housing space is formed below the flange portion and the boot is inserted and held together with the boot. The ring housing space protrudes radially outward and radially inward below the ring housing space. an elastic deformable projections in at least three locations around the axis, before the ring integrated portion is elastically deforming the projecting portion provided on the bush toward the radially inward Is inserted into the ring housing space, by inserting the bush from below the cylindrical member formed on the knob, the elastic deformation of the radially inner side of the protrusion is prevented by the presence of the tubular member It is characterized by that.

According to the present invention, when the upper part of the boot is mounted on the bush, the protrusion of the bush is elastically deformed radially inward, and the ring integrated part of the boot is inserted from below into the bush, so that the ring is accommodated in the ring receiving space. Place at the position. Thereafter, by attaching the bush to the tubular member on the lower side of the knob, the projection of the bush is prevented from being elastically deformed radially inward. Therefore, the upper part of the boot does not fall out of the bush.
According to this invention, with the upper part of the boot mounted on the bush, the bush is inserted into the shift lever together with the boot, and then the tubular member of the knob is inserted into the upper part of the shift lever protruding upward from the bush. Attach the knob to the top of the shift lever. Thereafter, when the bush is lifted upward, the cylindrical member is inserted inside the bush. Therefore, even if the protruding portion attempts to elastically deform inward in the radial direction, the presence of the cylindrical member is prevented. Therefore, the ring integrated part of the boot does not fall off from the bush.

The invention according to claim 2, in the shift lever device according to claim 1, the inner side of the protrusion while protrusion protruding toward the radially inward is formed on the outer peripheral surface of the tubular member Is formed with a recess, the protrusion is fitted into the recess when the bush is inserted into the cylindrical member, and the bush is attached to the knob.

  According to this invention, by inserting the bush into the cylindrical member, the convex portion formed on the inner peripheral surface of the bush fits into the concave portion formed on the outer peripheral surface of the cylindrical member, and the bush is prevented from coming off. . For this reason, the assembly | attachment property of the bush to a knob improves.

According to the shift lever device according to the present invention, since the bush is provided with the protrusion that elastically deforms with the ring accommodating space, the protrusion of the bush is elastically deformed radially inward when the upper part of the boot is mounted on the bush. Therefore, the ring integrated part at the upper part of the boot can be inserted into the bush from below, and when the ring is moved to the position of the ring accommodating space, the projection part returns to the original state, and the ring integrated part of the boot Will not come off the bush. Therefore, as before, it is necessary to reverse the inner and outer surfaces of the boot and attach the upper part of the boot to the bush, and after installation, the inner and outer surfaces of the boot are inverted again to return to the original state. There is no workability.
When the protrusion of the bush is elastically deformed radially inward, the ring integrated part of the upper part of the boot can be inserted into the bush from below, and the bush together with the boot is attached with the upper part of the boot attached to the bush. Inserting the knob into the shift lever, and then attaching the knob to the top of the shift lever and lifting the bush upward causes the cylindrical member to be inserted inside the bush. This is prevented by the presence of the tubular member. Therefore, the ring integrated part of the boot does not fall off from the bush.

  Embodiments of a shift lever device according to the present invention will be described below.

  The overall structure of the shift lever device is shown in FIG. A knob 3 is attached to an upper end portion of a shift lever 2 that is erected on a housing 1 so as to be rotatable. A rectangular cylindrical bush 4 is attached to the lower side of the knob 3, and the shift lever 2 is covered with the bush 4. The upper end of the boot 5 is attached. A lower end portion of the boot 5 is coupled to an indicator (not shown) provided on the upper portion of the housing 1. The indicator is attached to an opening provided in a vehicle floor console (not shown).

  As shown in FIG. 2 which is a cross-sectional view of the main part of FIG. That is, the upper part of the boot 5 is bent inward so as to wrap the ring 6 with the upper part of the boot 5, and the ring 6 is sewn into the upper part of the boot 5. As shown in FIG. 1, the ring 6 and the ring integrated part 5a are formed in a substantially square shape.

  Next, the bush 4 is configured as follows. As shown in FIG. 1, the entire bush 4 is formed in a substantially square cylindrical shape. A flange portion 4a having a diameter larger than that of the ring 6 is formed in the upper portion of the bush 4, and a ring receiving space 4b into which the ring 6 is inserted and held together with the boot 5 is formed below the flange portion 4a. Projections 4c projecting radially outward and elastically deforming radially inward are provided at four locations around the axis below 4b. As shown in FIG. 1, slits 4d are formed in the three surroundings excluding the lower portion of the protrusion 4c so that the protrusion 4c can be elastically deformed. Thereby, the protrusion 4c can be bent, and is elastically deformed by bending.

  Then, the ring integrated part 5 a at the upper part of the boot 5 is attached to the bush 4. That is, the ring integrated portion 5a is inserted into the ring housing space 4b from below in a state where the protruding portion 4c is elastically deformed by bending inward in the radial direction, and the protruding portion 4c is returned to return the ring integrated portion 5a. The downward slip is prevented.

  The bush 4 is attached to the lower side of the knob 3 attached to the shift lever 2. That is, as shown in FIG. 2, a cylindrical member 7 for mounting the knob 3 on the upper portion of the shift lever 2 is integrally formed inside the knob 3, and the lower portion of the cylindrical member 7 is the knob 3. Projecting from the lower side, the bush 4 is attached to the projecting portion. That is, the knob 3 is mounted on the upper portion of the shift lever 2 by inserting the upper portion of the shift lever 2 into the cylindrical member 7, and the bush 4 is inserted into the tubular member 7 by inserting the bush 4 from below. 3 is attached. The cylindrical member 7 is formed with slits 7a as recesses along the circumferential direction at four locations in the circumferential direction. On the other hand, a convex portion 4e having a substantially semicircular cross-sectional shape is formed on the inner side of each protruding portion 4c. Then, when the bush 4 is inserted from below the tubular member 7 and the bush 4 is moved up to a position where the upper surface of the bush 4 abuts on the lower side of the knob 3, the convex portion 4e is fitted into the slit 7a, and the knob 3 On the other hand, the bush 4 is positioned and fixed in the axial direction.

  As a result, the cylindrical member 7 is positioned inside the protruding portion 4c. Therefore, even if the protruding portion 4c is bent and elastically deformed radially inward, this elastic deformation is prevented by the presence of the cylindrical member 7. The

  As shown in FIG. 2, a slit 2a is formed in the upper part of the hollow shift lever 2 along the axial direction, and a detent 7b protruding inward from the cylindrical member 7 is fitted into the slit 2a. The knob 3 is regulated so as not to rotate with respect to the shift lever 2. A rod (not shown) is accommodated inside the shift lever 2, and when the knob button 3 a of the knob 3 is pressed, the detent coupling portion provided at the lower part of the shift lever 2 is pulled up via the rod, and the inside of the housing 1 Is removed from a detent groove portion (not shown). That is, the shift lever 2 is unlocked, and the shift lever 2 can be shifted.

  Next, a procedure for assembling the shift lever device will be described. As shown in FIG. 1, when the upper part of the boot 5 is mounted on the bush 4, the ring integrated part 5a of the boot 5 is attached to the bush 4 from below while the protrusion 4c of the bush 4 is elastically deformed radially inward. The ring 6 is inserted into the ring housing space 4b. Next, the boot 5 is inserted into the shift lever 2 from above the shift lever 2, and then the knob 3 is mounted on the upper portion of the shift lever 2. In order to mount the knob 3, the cylindrical member 7 protruding downward from the knob 3 is inserted into the upper portion of the shift lever 2, and the cylindrical member 7 is coupled to the shift lever 2 using a screw or the like (not shown). Thereafter, the bush 4 is inserted into the tubular member 7 from below. Then, the protrusion 4c of the bush 4 shown in FIG. 2 is slightly elastically deformed outward in the radial direction, and the protrusion 4e rides on the outer peripheral surface of the tubular member 7 and then enters the slit 7a, so that the bush 4 is positioned in the axial direction. And attached to the knob 3. And since the cylindrical member 7 is located inside the protrusion part 4c of the bush 4, the protrusion part 4c is blocked | prevented from elastically deforming radially inward. For this reason, the ring integrated part 5a of the boot 5 does not fall downward from the bush 4.

  In this embodiment, the shift lever device is applied to an AT vehicle, but may be applied to a manual vehicle. Moreover, although the case where the cross-sectional shape of the bush or the cylindrical member is a square is shown in the present embodiment, the cross-sectional shape is not limited to a square, and may be a circle or an ellipse. Further, it is sufficient that the protrusions are at least three around the shift lever. This is because if there are at least three places, the ring integrated portion is held so as not to fall. And it is desirable for the width | variety of a projection part to have a certain amount of magnitude | size along the circumferential direction of a shift lever. This is to prevent the ring integrated part from coming off from the bush or loosening. In addition, in this embodiment, the cylindrical member is integrally formed with the knob, but may be separately manufactured and coupled.
