The opening 13b1 corresponds to the “engagement portion” of the present invention.

  The shift lever device 1 is assembled by assembling the base bracket 2, the shift lever 3 and the buffer member 4. Hereinafter, an example of the assembly method of the shift lever device 1 will be described. As shown in FIG. 4, first, the buffer member 4 is prepared above the shift lever 3 so that the axis O of the rod 6 of the shift lever 3 and the axis O3 of the main body 12 of the buffer member 4 are located on the same line.

  Next, the lever portion 3 a (the pipe portion 5 and the rod 6) is inserted into the buffer member 4 from above the shift lever 3 with the base portion 13 of the buffer member 4 as the head. As the buffer member 4 is inserted into the lever portion 3a, the tip of the lever portion 3a protrudes from the upper end of the buffer member 4, and the buffer member 4 is inserted toward the lower end side of the lever portion 3a.

  When the buffer member 4 is inserted toward the lower end side of the lever portion 3a, the base of the buffer member 4 is adjusted while adjusting the position of the buffer member 4 so that the raised portion 10 of the shift lever 3 is accommodated in the opening 13b1 of the buffer member 4. The part 13 is inserted toward the tip of the support part 7.

  When the support portion 7 is inserted into the base portion 13, the side wall 13 b rides on the raised portion 10 from the lower end side of the base portion 13 and is elastically deformed so that the base portion 13 spreads outward. When the base portion 13 is elastically deformed, the support portion 7 is allowed to be inserted into the inside (back) of the base portion 13. And if the support part 7 is further inserted in the base part 13 from there, while the back surface 13c (refer FIG. 5) of the upper wall 13a of the base part 13 reaches | attains the upper surface 7a of the support part 7, and the side wall of the base part 13 13b gets over the raised portion 10 and the raised portion 10 is accommodated in the opening 13b1 (FIG. 8). When the raised portion 10 is stored in the opening portion 13b1, the base portion 13 that has been elastically deformed and expanded to get over the raised portion 10 is restored so that the inner peripheral portion of the opening portion 13b1 surrounds the root of the raised portion 10 To position. Therefore, even if the raised portion 10 is engaged with the opening 13 b 1 and the buffer member 4 is pulled toward the distal end side of the rod 6, the buffer member 4 does not come out of the support portion 7.

  As shown in FIG. 8, in the state where the buffer member 4 is attached to the shift lever 3, the main body portion 12 of the buffer member 4 includes the pipe portion 5 in which the pipe portion 5 of the lever portion 3 a protrudes from the upper surface 7 a of the support portion 7. Located at the root. Specifically, as shown in FIG. 4, the main body portion 12 is positioned along the pipe portion 5 to the root where the pipe portion 5 is connected to the upper surface 7 a of the support portion 7. Returning to FIG. 8, the base portion 13 of the buffer member 4 extends from the lower end of the main body portion 12 along the upper surface 7 a (see FIG. 4) of the support portion 7, and downward from the outer peripheral portion of the upper surface 7 a along the side surface 7 b. Located to extend.

  After mounting the buffer member 4 on the shift lever 3, the base bracket 2 is prepared above the shift lever 3 as shown in FIG. 2, and then the shift lever 3 is mounted on the base bracket 2. For example, the shift lever 3 is inserted into the base bracket 2 so that the pipe portion 5 protrudes from the inside to the outside of the base bracket 2 through the opening 2 a 1 of the base bracket 2. And the shift lever apparatus 1 is assembled by fixing the shift lever 3 to the base bracket 2 using the shaft part etc. which are not shown in figure. In the assembled shift lever device 1, for example, the shift lever 3 rotates around the axis O 2, so that the pipe portion 5 moves in the opening 2 a 1 of the base bracket 2. Since the buffer member 4 is attached to the pipe portion 5 that moves in the opening portion 2a1, it is possible to prevent the pipe portion 5 and the opening portion 2a1 from directly contacting each other, and no hitting sound is generated.

  In the shift lever device 1 configured as described above, the base portion 13 of the buffer member 4 is fitted to the support portion 7 that supports the lever portion 3a as shown in FIGS. Then, the buffer member 4 is attached to the shift lever 3. Therefore, it is easy to attach the buffer member 4 to the shift lever 3.

  As shown in FIG. 8, when the support portion 7 is fitted into the base portion 13, the raised portion 10 of the support portion 7 is accommodated in the opening portion 13 b 1 of the base portion 13, and the inner peripheral portion of the opening portion 13 b 1 is the base of the raised portion 10 ( (Peripheral part). Therefore, the opening 13b1 engages with the raised portion 10, the base portion 13 is fixed to the side surface 7b, and the displacement of the buffer member 4 attached to the shift lever 3 can be suppressed.

  As shown in FIG. 6, since the base portion 13 has a notch portion 13 b 2 that is notched in a convex shape upward from the lower end of the base portion 13, when the support portion 7 is fitted into the base portion 13, It is possible to disperse the generated stress. Also, the opening 13b1 contributes to disperse the stress, and the opening 13b1 and the notch 13b2 can synergistically disperse the stress.

  The embodiments of the present invention have been described above. However, the present invention is not limited to the specific description, and the illustrated configurations and the like can be appropriately combined within a technically consistent range. In addition, certain elements and processes may be replaced with known forms.

  In the above description, the buffer member 4 having the opening 13b1 and the notch 13b2 is illustrated, but a buffer member having only one of them or a buffer member having neither of them may be used.

  In the above description, the raised portion 10 is exemplified as the engaged portion, but a leaf spring-like claw portion may be used. For example, the claw portion is formed so as to extend downward from the side surface 7b gradually starting from the upper end portion of the side surface 7b and then to extend downward along the side surface 7b. The claw portion is biased in a direction in which the claw portion is separated from the side surface 7b based on elastic deformation at the base point.

  When the buffer member 4 is mounted on the support portion 7 using this claw portion, when the support portion 7 is inserted into the base portion 13, the side wall 13b rides on the claw portion from the lower end side of the base portion 13, The claw portion is elastically deformed so as to be along the side surface 7 b side of the support portion 7. When the claw portion is elastically deformed, the support portion 7 is allowed to be inserted into the base portion 13 (back). And if the support part 7 is further inserted in the base part 13 from there, while the back surface 13c (refer FIG. 5) of the upper wall 13a of the base part 13 reaches | attains the upper surface 7a of the support part 7, and the side wall of the base part 13 13b gets over the claw part and the claw part is stored in the opening part 13b1. The claw part accommodated in the opening part 13b1 is urged in a direction away from the side surface 7b of the support part 7, and the tip of the claw part is positioned along the inner peripheral part of the opening part 13b1. Therefore, even if the claw portion engages with the opening portion 13 b 1 and the buffer member 4 is pulled toward the distal end side of the rod 6, the buffer member 4 does not come out of the support portion 7.
