Next, the operation of this embodiment will be described.

In the shift device 10 having the above configuration, the lever 16 is held at the “H” position by the biasing force of the moderating mechanism, and the lever 16 is rotated from the “H” position against the biasing force of the moderating mechanism. It Also, the periphery of the lever 16 is covered with the boot 20 between the housing 12 and the knob 18.

Here, the boot 20 is elastically stretched between the housing 12 and the knob 18 when the lever 16 is placed in the “H” position. Therefore, not only when the lever 16 is arranged at the “H” position but also when the lever 16 is rotated from the “H” position, it is possible to prevent the boot 20 from being loosened. As a result, it is possible to prevent the occupant's fingers from being caught by the slack of the boot 20 and hindering the occupant from gripping the knob 18, and also to prevent solids or liquid from entering (for example, accumulating) in the slack of the boot 20. In addition, the appearance of the boot 20 can be improved, and the need for providing a space for the looseness of the boot 20 to enter the fixing frame 22 of the housing 12 can be reduced, and the shift device 10 can be downsized.

Further, when the lever 16 is arranged at the “H” position, the boot 20 is elastically stretched between the housing 12 and the knob 18 in the generatrix direction and the circumferential direction. Therefore, it is possible to effectively suppress the occurrence of slack in the boot 20 not only when the lever 16 is arranged at the “H” position but also when the lever 16 is rotated from the “H” position.

Moreover, when the lever 16 is placed in the “H” position, the boot 20 is elastically stretched between the housing 12 and the knob 18 in the entire generatrix direction and the entire circumferential direction. Therefore, it is possible to prevent the slack from occurring in the boot 20 when the lever 16 is arranged in the “H” position, and also to prevent the slack in the boot 20 when the lever 16 is rotated from the “H” position. The occurrence can be effectively suppressed.

Further, when the rotational operation force is not applied to the lever 16, the lever 16 is held in the “H” position, and the boot 20 is elastically stretched between the housing 12 and the knob 18. Therefore, it is possible to increase the chances that the slack of the boot 20 can be suppressed.

Further, the boot 20 is elastically stretched between the housing 12 and the knob 18 when the lever 16 is arranged at the operation intermediate position (in the present embodiment, the “H” position which is the operation center position in the front-rear direction). .. Therefore, the operation amount (rotation amount) from the intermediate operation position of the lever 16 to the operation restricting position (the “B” position, the “R” position, and the “D” position in the present embodiment) can be reduced, and the lever 16 restricts the operation. Even when the boot 20 is arranged at the position, it is possible to suppress the occurrence of slack in the boot 20.

Also, the lever 16 can be rotated to a specific position (for example, the “H” position) by the elastic contraction force of the boot 20. Therefore, the elastic contraction force of the boot 20 can assist the rotation of the lever 16 to the specific position.

Further, when the lever 16 is arranged in the “H” position, the outer peripheral surface of the boot 20 is smoothly continuous with the inclined surface 12A of the housing 12 and the peripheral surface of the knob 18 over the entire circumference. Therefore, the appearance of the shift device 10 can be improved.

Also, a mating portion 20A on the outer peripheral surface of the boot 20 is arranged on the front part of the boot 20 (on the side opposite to the eyes of the occupant). Therefore, it is possible to prevent the occupant from visually recognizing the mating portion 20A, and to improve the appearance of the boot 20.

Furthermore, the boots 20 limit the passage of liquid. Therefore, it is possible to limit the infiltration of the liquid into the inside of the boot 20 in the radial direction (in particular, inside the housing 12).
