However, in the present embodiment, the pressing portion 74 has a shape that gradually inclines toward the lower surface of the bottom plate 30 as it approaches the tip portion 94.

The operating member 70 is held by the bottom plate 30 so as to be displaceable with respect to the bottom plate 30 between the pressing position (the position shown in FIG. 14) and the separated position (the position shown in FIG. 13). ..

The pressing position is a position where the tip portion 94 is pressed toward the installation surface 100 so that the non-slip member 50 is in the contact state. The pressing portion 74 presses the tip portion 94 toward the installation surface 100 in a state of being inserted between the bottom plate 30 and the tip portion 94 at the pressing position. The separation position is a position where the non-slip member 50 is separated from the tip portion 94 so as to be in the separated state.

In this embodiment, the operator displaces the operating member 70 to the pressing position in the operating space S, so that the non-slip member 50 is switched from the separated state to the contact state and the state is maintained. On the other hand, when the operator displaces the operating member 70 to the separated position, the elastic member 90 returns to the neutral position, and the non-slip member 50 is maintained in the separated state.

It should be noted that the embodiments disclosed this time are exemplary in all respects and are not restrictive. The scope of the present invention is shown by the scope of claims rather than the above description, and is intended to include all modifications within the meaning and scope equivalent to the scope of claims.
