Abstract

PROBLEM TO BE SOLVED: To provide a shift device in which locking of a locking part is prevented from being released.SOLUTION: In a shift lever device 10, a cushion 32 is locked on a detent plate 26 by inserting a fitting claw 34 of the cushion 32 into a fitting hole 38 of the detent plate 26, and a detent pin 24 of a shift lever 16 comes into contact with an absorbing groove 44 of the cushion 32 when the detent pin 24 is displaced to an upper side of an axial direction of the shift lever 16. In this state, in a portion between the absorbing groove 44 of the cushion 32 and the fitting claw 34, a rib 40 of the detent plate 26 is fit into a fit-in hole 42 of the cushion 32. When the detent pin 24 is brought into contact with the absorbing groove 44, the rib 40 can prevent an impact force applied from the detent pin 24 to the absorbing groove 44 from being transmitted to the fitting claw 34, and a deformation of the fitting claw 34 can be suppressed so that the locking of the cushion 32 on the detent plate 26 can be prevented from being released.

Description

  The present invention relates to a shift device in which a shift position is changed by moving a shift member.

  In the shift lever device described in the following Patent Document 1, the shift lever's position pin is displaced, so that the shift lever's movement restriction and allowance are switched by the step opening of the position plate. Further, an absorption plate is attached to the position plate, and the position pin interferes with the absorption plate, and the absorption plate absorbs the impact from the position pin.

  However, in this shift lever device, for example, the hook portion of the absorption plate is locked in the hole for the hook portion of the position plate, and the absorption plate is attached to the position plate. For this reason, when the strength of the collar is low, when the position pin interferes with the absorption plate, the impact from the position pin is transmitted to the collar and the collar is deformed. There is a possibility that the locking of the buttocks to the door will be released.

  A substantially rectangular plate-shaped cushion 32 as an absorbing member is attached to the vehicle left side of the detent plate 26. The cushion 32 is made of an elastic resin (for example, urethane resin) and has a detent groove 30 ("" (Except for the part corresponding to the “P” shift position).

  As shown in FIGS. 3 and 4, the upper portion of the cushion 32 is integrally formed with a fitting claw 34 as a locking portion at the vehicle front side portion and the vehicle rear side portion. It protrudes from the cushion 32 to the right side of the vehicle. The fitting claw 34 is provided with a substantially cylindrical base end portion 34A and a substantially conical tip end portion 34B on the same axis, and the diameter of the end portion on the base end portion 34A side of the tip end portion 34B is the base end.

The fitting claw 34 is formed with a rectangular through hole 36 as a strength-decreasing portion. The through hole 36 includes a distal end portion 34B side portion of the proximal end portion 34A and a proximal end portion 34A side portion of the distal end portion 34B. Is penetrated (stretched) in the rotational radial direction of the shift lever 16 (the opposing direction of the fitting claw 34 and the lateral surface 30A) to reduce the strength of the fitting claw 34.

  The detent plate 26 is formed with a circular fitting hole 38 as a locked portion so as to correspond to each fitting claw 34, and the fitting claw 34 has a distal end portion in the fitting hole 38. 34B is elastically deformed and the base end 34A is inserted. The detent plate 26 is fitted (clamped) between the cushion 32 and the distal end portion 34B of the fitting claw 34, whereby the cushion 32 is locked and attached to the detent plate 26.

  The detent plate 26 is integrally formed with a rectangular columnar rib 40 as an engaging portion between each fitting hole 38 and the detent hole 28 in the rotational radius direction of the shift lever 16. It protrudes from the detent plate 26 to the left side of the vehicle, and the longitudinal direction of the cross section in the vertical direction of the protrusion is directed to the rotational circumferential direction of the shift lever 16.

  In the lower part of the cushion 32, a rectangular insertion hole 42 as an engaged portion is formed so as to correspond to each rib 40, and the rib 40 is inserted (engaged) into the insertion hole 42. Yes. Thereby, the movement of the cushion 32 with respect to the detent plate 26 is restricted.

  An absorption groove 44 having a predetermined shape as an absorption portion is formed on the lower surface of the cushion 32, and the absorption groove 44 has an uneven shape corresponding to the detent groove 30 of the detent plate 26 (detent hole 28). . The absorption groove 44 is provided with a lateral surface 44A, and the lateral surface 44A is arranged in parallel with the lateral surface 30A slightly below the lateral surface 30A of the detent groove 30. The absorption groove 44 is provided with a vertical surface 44B. The vertical surface 44B is flush with the vertical surface 30B of the detent groove 30 and is arranged in parallel with the vertical surface 30B. When the detent pin 24 of the shift lever 16 is displaced upward in the axial direction of the shift lever 16 by the urging force of the compression coil spring 22 and interferes with the lateral surface 30A, the detent pin 24 contacts (interference) with the lateral surface 44A. To do.

  Next, the operation of this embodiment will be described.

  In the shift lever device 10 having the above configuration, when the knob button 18 is pressed in the shift lever 16, the detent pin 24 is integrated with the detent rod 20 against the urging force of the compression coil spring 22. Displaced downward in the axial direction.

  When the shift lever 16 is rotated while the knob button 18 is not pressed and the detent pin 24 is not displaced downward in the axial direction of the shift lever 16, the detent pin 24 is moved to the detent plate 26 (detent hole 28). ), The rotation of the detent pin 24 is restricted, so that the turning operation of the shift lever 16 is restricted and the shift position of the shift lever 16 is changed. Be regulated.

  On the other hand, when the knob lever 18 is pressed and the detent pin 24 is displaced downward in the axial direction of the shift lever 16, the detent pin 24 always moves when the shift lever 16 is rotated. Since the rotation of the detent pin 24 is permitted without interfering with the vertical surface 30B of the 30, the rotation operation of the shift lever 16 is permitted, and the change of the shift position of the shift lever 16 is permitted.

  When the pressing operation of the knob button 18 is released, the detent pin 24 is displaced upward in the axial direction of the shift lever 16 by the urging force of the compression coil spring 22 integrally with the detent rod 20, so that the detent groove 30 Interfers with the lateral surface 30A. At this time, except when the shift lever 16 is disposed at the “P” shift position, the detent pin 24 comes into contact with the lateral surface 44A of the absorption groove 44 of the cushion 32, so that the detent pin 24 moves to the lateral surface 30A. The impact is absorbed and the generation of interference sound on the lateral surface 30A of the detent pin 24 is suppressed.

  By the way, the fitting claw 34 of the cushion 32 is inserted into the fitting hole 38 of the detent plate 26 by the elastic deformation of the distal end portion 34B, and the detent plate 26 is inserted into the cushion 32 and the distal end portion 34B of the fitting claw 34. The cushion 32 is locked and attached to the detent plate 26. For this reason, unlike the case where the cushion 32 is attached to the detent plate 26 with other parts (for example, push nuts), the number of mounting steps and the number of parts can be reduced, and the cost can be reduced.

  Here, the radial direction of the shift lever 16 between the absorption groove 44 of the cushion 32 (the lateral surface 44A on the contact side of the detent pin 24) and the fitting claw 34 (the direction of contact of the detent pin 24 with the lateral surface 44A). ), The rib 40 of the detent plate 26 is inserted into the insertion hole 42 of the cushion 32. For this reason, when the pressing operation of the knob button 18 is released and the detent pin 24 comes into contact with the lateral surface 44A of the absorption groove 44 by the urging force of the compression coil spring 22, an impact (from the detent pin 24 to the lateral surface 44A) The load 40 can be restricted from being transmitted to the fitting claw 34, and the fitting claw 34 can be prevented from being deformed. Thereby, it can suppress that the latching of the cushion 32 to the detent plate 26 is cancelled | released, and it can suppress that the cushion 32 falls from the detent plate 26. FIG.

  In addition, the longitudinal direction of the cross section in the protruding vertical direction of the rib 40 is directed in the rotational circumferential direction of the shift lever 16. For this reason, as described above, when the detent pin 24 abuts against the lateral surface 44A of the absorption groove 44 by the urging force of the compression coil spring 22, the impact from the detent pin 24 to the lateral surface 44A is transmitted to the fitting claw 34. This can effectively restrict the rib 40 and prevent the fitting claw 34 from being deformed. Thereby, it can suppress effectively that the latching of the cushion 32 to the detent plate 26 is cancelled | released, and it can suppress effectively that the cushion 32 falls from the detent plate 26. FIG.

  Further, since the rib 40 of the detent plate 26 is made of metal and the fitting claw 34 of the cushion 32 is made of resin, the strength of the rib 40 is higher than the strength of the fitting claw 34. For this reason, as described above, when the detent pin 24 abuts against the lateral surface 44A of the absorption groove 44 by the urging force of the compression coil spring 22, the impact from the detent pin 24 to the lateral surface 44A is transmitted to the fitting claw 34. That is, the rib 40 can be more effectively restricted, and the fitting claw 34 can be more effectively prevented from being deformed. Thereby, it can suppress more effectively that latching of the cushion 32 to the detent plate 26 is cancelled | released, and it can suppress more effectively that the cushion 32 falls from the detent plate 26. FIG.

  Further, the strength of the fitting claw 34 is set lower than that of the rib 40. For this reason, the fitting claw 34 can be easily elastically deformed, the fitting claw 34 can be easily inserted into the fitting hole 38, and the cushion 32 can be easily locked and attached to the detent plate 26.

  Moreover, in the fitting nail | claw 34, the through-hole 36 is formed and the intensity | strength is reduced. For this reason, the fitting claw 34 can be elastically deformed more easily, the fitting claw 34 can be inserted into the fitting hole 38 more easily, and the cushion 32 can be locked and attached to the detent plate 26 more easily. .

  Further, in the fitting claw 34, the through hole 36 is penetrated in the rotational radial direction of the shift lever 16 (direction in which the detent pin 24 abuts on the lateral surface 44A). For this reason, it is possible to suppress the strength of the fitting claw 34 from decreasing in the rotational radial direction of the shift lever 16, and the detent pin 24 still has the lateral surface 44 </ b> A of the absorption groove 44 due to the urging force of the compression coil spring 22 as described above. It can suppress that the fitting nail | claw 34 deform | transforms when contacting.

  In the present embodiment, the fitting pawl 34 is provided as a locking portion in the cushion 32 and the fitting hole 38 is provided as a locked portion in the detent plate 26. However, the fitting hole 38 may be provided in the cushion 32 as a locking portion or a locked portion, and the fitting claw 34 may be provided in the detent plate 26 as a locked portion or a locking portion. In this case, the fitting claw 34 may be elastically deformable.

  Furthermore, in this embodiment, the through-hole 36 was provided in the fitting nail | claw 34, and it was set as the strength reduction part. However, the fitting claw 34 may be provided with a portion having a strength lower than that of the other portion to be a strength reduced portion.

  In the present embodiment, the detent plate 26 is provided with the rib 40 and the cushion 32 is provided with the fitting hole 42. However, the insertion hole 42 may be provided in the detent plate 26 and the rib 40 may be provided in the cushion 32.

  Further, in the present embodiment, the strength of the rib 40 is higher than the strength of the fitting claw 34. However, the strength of the rib 40 may be lower than the strength of the fitting claw 34.

  Further, in the present embodiment, the cushion 32 (particularly the lateral surface 44A) is not provided at a portion corresponding to the “P” shift position of the shift lever 16 in the detent groove 30 of the detent plate 26. However, the cushion 32 (particularly the lateral surface 44 </ b> A) may be provided at a portion corresponding to the “P” shift position of the shift lever 16 in the detent groove 30 of the detent plate 26.

  Furthermore, in this embodiment, the vertical surface 44B of the absorption groove 44 of the cushion 32 is flush with the vertical surface 30B of the detent groove 30 of the detent plate 26. However, the vertical surface 44B of the absorption groove 44 of the cushion 32 may be arranged inside the detent hole 28 from the vertical surface 30B of the detent groove 30 of the detent plate 26.
