- the cam 31 rotates in the opposite direction to when the key 80 is inserted, the rod 32 moves in the longitudinal direction, and the rod 32 moves in the longitudinal direction.
- the first part 321 of 32 slides along the circumferential surface of the cam 31 and comes into contact with the nose 314 . That is, in order for the key 80 to be withdrawn from the head 20, the rod 32 must be able to move in the longitudinal direction. Therefore, if the movement of the rod 32 is restricted, the user cannot withdraw the key 80 from the head 20 .
