PROBLEM TO BE SOLVED: To solve the problem where an object falls accidentally, when it is unhooked off a screw under an external force from below to the object mounted on a wall. SOLUTION: A mounting hole 2b provided at a rear surface plate 2a of an object 2 is engaged with a screw 3 provided on a wall surface 1, so that the object 2 is fitted to the wall surface. Here, a wall-mounting means 4 is provided which comprises a horizontal groove 4e, where the vertical width is smaller than a head part 3a of the screw 3 and a vertical groove 4h where, communicating with the horizontal groove 4e by its bottom, a horizontal width is smaller than the head part of the screw 3. The vertical movement of the object 2 is regulated by a lower part rib 4b, even under an external force, from below, on the object 2 mounted on the wall surface 1, so that the object 2 will not accidentally come off the screw 3 nor drop.
