That is, when the rod member 310 completely protrudes from the lower housing 200, the holding part is in a state as shown in FIG. 2A. As the rod member 310 is pressed into the lower housing 200, the jaw portion 313 of the rod member moves to the position of the ball 250 as shown in FIG. 2B.

When the force is further applied to the rod member 310, the jaw portion 313 moves the ball 250 to the position of the inner circumferential groove 353 of the cover member 350 so that the ball is received in the inner circumferential groove. When the ball is accommodated in the inner circumferential groove, the jaw portion 313 is able to pass the ball 250 and is moved to the head 331 of the support pin 330.

When the jaw portion 313 passes completely through the ball 250, the ball is released from the inner circumferential groove 353 by its own weight and returns to the initial position. In this case, as the force applied to the rod member 310 is removed, as shown in FIG. 2C, the rod member is held by the ball 250.
