Reference numeral 11 denotes one of two relatively movable members (for example, an apparatus main body and an opening / closing unit). The formed support surface 12 is a locking piece provided on the other of the two, and its tip is movable substantially at right angles to the support surface 11. Reference numeral 13 denotes a claw provided on the support surface 11 for fixing the locking piece 12 to the support surface 11. FIGS. 2A and 2B are a front view and a sectional view showing the claw 13. The claw 13 is made of an elastic material such as resin, and is provided so as to be substantially upright on the support surface 11 and to be able to bend elastically in a state shown by a two-dot chain line. Further, the claw 13 has a locking surface 14 provided opposite to the support surface so as to be able to restrain the locking piece 12 between the support surface 11 and a hole 15 penetrating through a post portion of the claw. I have. The locking surface 14 is also formed on the hole 15 in the column portion of the claw 13, and therefore is also formed at a position overlapping the center point O when the claw is bent. A slope 16 is formed on the head of the claw 13, and when the locking piece 12 is pushed down,
The nail 13 can be bent.

Is pressed in the direction of arrow P. However, since the locking surface 14 is formed at a position overlapping the center point O when the claw 13 bends, no moment about the center point O is generated on the claw 13 even when a force in the direction of the arrow P acts. . For this reason, the claw 13 does not bend and does not come off from the locking piece 12.

Other configurations are the same as those of the embodiment of FIGS. 1 and 2, and corresponding components are denoted by the same reference numerals. Also in this embodiment, since the locking surface 14A is formed at a position overlapping the center point O when the claw 13A is bent, even if a force in the direction of the arrow P acts on the locking piece 12, the center point O is applied to the claw 13A.

In this embodiment, the head of the claw 13B is formed more deeply in the locking piece insertion direction than the pillar. The locking surface 14B is also formed on the back side of the position overlapping with the center point O when the claw is bent. Other configurations are the same as those of the embodiment of FIGS. 1 and 2, and corresponding portions are denoted by the same reference numerals. In this embodiment, as shown in FIG. 5, when a force in the direction of arrow P
At B, a clockwise moment M2 is generated around the center point O. Since this is a moment to bend the claw 13B in the direction opposite to the direction in which the claw 13B is removed from the locking piece 12, the claw 13B
Is more difficult to come off.

Is a locking piece that can move almost at right angles to the support surface,
A hole for locking the tip of the locking piece of
Can bend almost vertically and elastically
So that the tabs are locked by hooks
As a result, even if a force is applied in the direction in which the locking piece moves vertically away from the support surface, there is no moment generated in the claw that deflects the claw in the direction away from the tip of the locking piece. Has the effect that it does not come off from the locking piece.
