Description

  The present invention relates to a shift lever device for performing a shifting operation of a vehicle.

  As a structure for connecting two parts to each other, a technique is disclosed in which a claw is formed on one part and a hooking part on which the claw is hooked is formed on the other part (see Patent Document 1). And the member for exclusive use which prevents a nail | claw from removing from a hook part is provided, and the nail | claw is clamped between this member and a hook part.

JP 2004-106776 A

  However, in the conventional structure, since a dedicated member is newly provided to prevent the claw from coming off from the hook portion, there is a problem that the cost is increased and the weight of the entire device is increased. . This problem is also a problem that applies in common when the structure is applied to a shift lever device.

  Therefore, the present invention provides a shift lever device that can reduce the cost and weight by properly connecting two components without newly providing a dedicated member for preventing the claw from coming off. This is the issue.

In order to solve the above problems, the present invention provides a lever body that is swingably supported with respect to a base bracket, an operation knob having an insertion hole into which the lever body is inserted, and the lever body is inserted. A shift lever device having a through hole and a lever cover that swings as the lever body swings, wherein either one of the operation knob or the lever cover is provided with a holding claw. together, the operating knob or the other of the lever cover, the holding claws hooked portion provided to be hooked, wherein one of the holding claws or the hook portion is configured to have a flexible, said retaining It is sandwiched between the claw or any other as the lever body of the hook, in the assembled state of the shift lever device, the holding claws or the hook portion Deviation or of one, a portion corresponding to the upper side and the lower side of the gripping claws, characterized in that it is provided to be in contact with the lever body.

  According to the present invention, either one of the holding claw or the hook portion having flexibility is sandwiched between the other one of the holding claw or the hook portion and the lever main body, so that the lever main body is Since it also has the function of preventing the holding claw from coming off from the hook, it is not necessary to prepare a new member separately to prevent the holding claw from coming off, and the operation knob and lever cover can be connected well while reducing costs. It can be reduced and the weight can be reduced.

  According to the present invention, the cost can be reduced and the weight can be reduced by properly connecting the two components without newly providing a dedicated member for preventing the nail from coming off.

  Next, an example of the assembly process of the lever main body 21, the operation knob 22, and the lever cover 3 will be described with reference to FIGS.

  First, the operation knob 22 is fitted into the recess 31 of the lever cover 3 from above, and the hook portion 22d of the operation knob 22 is inserted into the insertion hole 34 of the lever cover 3 (see FIG. 4). At this time, the hook portion 22d is inserted into the insertion hole 34 of the lever cover 3 while the vertical surface 22g of the hook portion 22d is in sliding contact with the outer surface of the support portion 33a (see FIG. 6A).

When the hook portion 22d is inserted into the insertion hole 34 of the lever cover 3, the contact surface 33d comes into contact with the inclined surface 22h, but resists the restoring force of the support portion 33a (force to return to the initial state). Then, by pushing the hooking portion 22d downward, the support portion 33a is bent inward (being pushed and bent inward), and the claw portion 33b is also moved inward (see FIG. 6B). Further, when the inclined surface 22h gets over the contact surface 33d, the support portion 33a is restored, the claw portion 33b enters into the engaging hole 22f, and the engaging surface 33c of the claw portion 33b engages with the engaging hole 22f. Engaging with the mating surface 22i, the claw portion 33b is hooked into the retaining hole 22f (see FIG. 6C).
The operation knob 22 is fixed to the lever cover 3 through the above steps.

Next, the lever body 21 is inserted into the through hole 32 of the lever cover 3 and the insertion hole 22b of the operation knob 22 from below (see FIG. 4). Then, the screw N is screwed into the screw hole 21a of the lever main body 21 from the indicator installation portion 22a side of the operation knob 22, and the screw N is tightened.
The lever main body 21 is fixed to the operation knob 22 through the above steps.
When a downward load is applied to the lever cover 3, a force to deform the holding claw 33 is applied to the holding claw 33. By providing the lever main body 21 along the inner surface of the holding claw 33, the holding claw 33 Since the deformation of 33 is prevented, it is possible to reliably prevent the claw portion 33b from coming off from the retaining hole 22f.

  According to the shift lever device 1 according to the present embodiment described above, the lever main body 21 also has a function of preventing the claw portion 33b from coming off from the hooking hole 22f, and thus a new prevention of the claw portion 33b from coming off. There is no need to prepare a separate member, the cost can be reduced and the weight can be reduced while the operation knob 22 and the lever cover 3 are connected well.
