The projection 21 is completely received in the groove 31, the tip of the projection 21 does not contact the bottom of the groove 31, and the projection 21 gradually approaches the step 32 in the groove 31 as the pressing rod 3 moves. Meanwhile, as the pressing portion 4 moves in the upward pressing direction, the interlinking lever 3a also moves in the pressing direction like the pressing lever 3, and as shown in fig. 1, the interlinking lever 3a moves upward to push the slider 5 to move rightward in the figure, and at this time, as shown in fig. 5(a), the slider 5 gradually moves rightward, and the hook 7 is still hung on the slider 5 at this time.

As the user continues to press the pressing portion 4 as shown in fig. 4(b), the base of the projection 21 abuts against the side surface of the step 32, and at this time, as shown in fig. 5(b), the contact area between the hook 7 and the slider 5 is only a small area.
