When the rotating body 59 rotates around the axis of the first shaft portion 591, the claw portion 60 fixed to the outer peripheral surface of the first shaft portion 591 also rotates around the axis of the first shaft portion 591. The protruding portion 60a of the claw portion 60 is disengaged from the locking groove 62a of the locking portion 62 (see the protruding portion 60a shown by a virtual line in FIG. 16). As a result, the movement of the second member 52 with respect to the first member 51 (movement in the front-rear direction) is allowed. Therefore, the armrest 20 can move in the front-rear direction (longitudinal direction of the armrest 20).

When the grip portion 532 of the operating lever 53 is gripped and pushed downward, the rocking body 58 swings downward around the swing fulcrum 531 and the second rotating body 59 inserted into the insertion portion 58a of the rocking body 58. The shaft portion 592 is pushed downward. Therefore, the second shaft portion 592 rotates downward around an axis extending in the front-rear direction, and the rotating body 59 rotates in the other direction around the axis of the first shaft portion 591 (in the direction opposite to the arrow C1 in FIG. 16). As a result, the protruding portion 60a of the claw portion 60 is inserted into the locking groove 62a of the locking portion 62. As a result, the armrest 20 is prevented from moving in the front-rear direction (longitudinal direction of the armrest 20).

The position of the armrest 20 in the front-rear direction can be adjusted by which of the plurality of protrusions 60a of the claw portion 60 is inserted into the locking groove 62a. For example, when the central protrusion 60a of the three protrusions 60a of the claw portion 60 is inserted into the locking groove 62a (see FIG. 18B), the position of the armrest 20 is the most reference position. When the front protrusion 60a is inserted into the locking groove 62a (see FIG. 18C), the position of the armrest 20 is behind the reference position. When the rearmost protruding portion 60a is inserted into the locking groove 62a (see FIG. 18A), the position of the armrest 20 is in front of the reference position.

In FIG. 2, an example of the position when the armrest 20 moves forward is shown by the virtual line 20X, and an example of the position when the armrest 20 moves backward is shown by the virtual line 20Y.
