In this state, the upright piece 13 and the falling-off prevention piece 17 are located between the left and right edges 30a, 30a of the cutout portion 30, so that they are prevented from moving in the axial direction (longitudinal direction) of the armrest 35. Furthermore, since the locking piece 32 is located on the front side of the overhanging part 16, the overhanging part 16 does not move forward, and therefore the rising piece 13 is also prevented from being pulled out forward from the missing part 30. be done. Due to these reasons, in the above state, main body A is attached to fixture B.
It is in a temporarily fixed state where it is completely prevented from falling off. After that, the tightening screw rod 22 is turned to move the tightening piece 18 upward in the same manner as in the above case, and the hanging piece 14 is
If the right and left edges 30a, 30a of the missing portion 30 are tightened by the left and right projecting portions 16, 16 of the tightening piece 18 and the right and left projecting portions 20, 20 of the tightening piece 18, a complete installation will be achieved.

In the case of the above-mentioned temporarily fixed state, even if only one of the locking pieces 32 is used, the above-mentioned falling-off prevention effect can be exerted.
That is, as shown in FIG. 5, when the upright piece 13 tries to come out of the cutout part 30, the upright piece 13 draws an arc centering on the part of the overhanging part 16 that abuts the locking piece 32. However, such movement is prevented by the upright piece 13 coming into contact with one edge 30a of the cutout 30. For this reason, the upright piece 13 cannot move, and the above-mentioned falling-off prevention effect is exhibited.

Next, when attaching to the wall of a building using the fixture B shown in FIG. 6, first attach the mounting portion 25 of the fixture B to the wall to be mounted with the abutting piece 33 removed.
