  Next, the operation of this embodiment will be described.

  In the shift device 10 configured as described above, the moderation pin 22 (the pin 24 and the moving collar 26) and the spring 28 are inserted into the guide hole 20A in the guide collar 20 of the lever 16, and the moving collar is provided on the peripheral surface of the guide hole 20A. 26, the lower surface of the pin 24 of the moderation pin 22 is brought into contact with the moderation surface 30A of the detent block 30 by the biasing force of the spring 28, and the lever 16 is biased by the biasing force of the spring 28. Has been.

  Here, the detent block 30 (moderation surface 30A) is made of resin. For this reason, the detent block 30 can be reduced in weight and the shift apparatus 10 can be reduced in weight.

  Further, when the dimension below the rotation center of the lever 16 (the center of the spherical shaft 16A) is reduced, the rotation stroke of the lower surface of the pin 24 is reduced. For this reason, in the moderation surface 30A, the inclination angle of the valley portion 30C with respect to the left-right direction is increased, and the inner angles of the valley portion 30C and the peak portion 30D (for example, the inner angle in a plane perpendicular to the left-right direction) are reduced. It is necessary to secure a biasing force applied to the lever 16 by reducing the angle of inclination of the pin 24 in the axial direction.

  Here, the pin 24 of the moderation pin 22 is made of resin. For this reason, the elastic modulus of the pin 24 can be reduced, and the contact pressure of the lower surface of the pin 24 to the moderation surface 30A can be reduced. Accordingly, even if the axial inclination angle of the pin 24 with respect to the moderation surface 30A is reduced as described above, the moderation surface 30A can be prevented from being worn by the lower surface of the pin 24, and the guide hole 20A peripheral surface of the lever 16 can be prevented. Further, the outer peripheral surface 26A of the moving collar 26 of the moderation pin 22 can be prevented from being worn, and the moderation pin 22 can be prevented from rattling with respect to the guide hole 20A.

  Further, when the inner angle of the peak portion 30D is reduced on the moderation surface 30A as described above, the lower surface of the pin 24 interferes with the peak portion 30D by reducing the radius of curvature of the lower surface of the pin 24 (the lower surface of the pin 24). Is obstructed by the crest 30D).

  Here, as described above, the pin 24 of the moderation pin 22 is made of resin, so that the contact pressure of the lower surface of the pin 24 to the moderation surface 30A is reduced. Therefore, even if the radius of curvature of the lower surface of the pin 24 is reduced as described above, the moderation surface 30A can be suppressed from being worn by the lower surface of the pin 24, and the peripheral surface of the guide hole 20A of the lever 16 and the movement of the moderation pin 22 can be suppressed. The collar 26 outer peripheral surface 26A can be prevented from being worn, and the moderation pin 22 can be prevented from rattling with respect to the guide hole 20A.

  Furthermore, the guide collar 20 (the peripheral surface of the guide hole 20A) of the lever 16 and the moving collar 26 (the outer peripheral surface 26A) of the moderation pin 22 are made of metal. For this reason, it can suppress effectively that the peripheral surface of guide hole 20A and the outer peripheral surface 26A of the movement collar 26 are worn, and it can suppress effectively that the moderation pin 22 rattles with respect to the guide hole 20A. In addition, it is possible to prevent the moderation pin 22 from rattling with respect to the guide hole 20A due to thermal expansion (linear expansion) of the guide collar 20 and the moving collar 26.

  As described above, when the rotation operation of the lever 16 in each direction is started, it can be suppressed that the moderation pin 22 rattles against the guide hole 20A and the urging force of the spring 28 is not applied to the lever 16. Can improve the operation feeling.

  Further, as described above, the dimension below the rotation center of the lever 16 can be reduced, and the rotation stroke of the lower surface of the pin 24 can be reduced. Therefore, the vertical dimension of the lever 16 and the dimension of the detent block 30 (moderation surface 30A) in the front-rear direction and the left-right direction can be reduced, and the shift device 10 can be reduced in size in the vertical direction, the front-rear direction, and the left-right direction.

  In the present embodiment, the lever 16 is provided with the guide hole 20A, the moderation pin 22 and the spring 28, and the detent block 30 is provided with the moderation surface 30A. However, the lever 16 may be provided with the moderation surface 30A, and the detent block 30 may be provided with the guide hole 20A, the moderation pin 22 and the spring 28.

  In this embodiment, the shift device 10 is a floor type and installed on the floor of the passenger compartment. However, the shift device 10 may be installed on an instrument panel or a steering column in the passenger compartment.
