In the structure, an appliance mounting hole provided in the wall board and a female screw on the inner peripheral surface are arranged coaxially with the appliance mounting hole on the back side of the appliance mounting hole and adhered to the wall board. An inner screw ring and a base member having a male screw screwed into a female screw of the inner screw ring, inserted into the space behind the wall through the instrument mounting hole, and a back end surface adhered to the vertical surface, A structure in which the device is fixed to the base member, wherein the inner screw ring is substantially C-shaped with a slit having a circumferential width larger than the thickness of the wall board.

According to the method of mounting an appliance on a wall according to the present invention, an appliance mounting hole is provided in a wall board, and an inner screw ring is disposed coaxially with the appliance mounting hole on the back side of the appliance mounting hole. A base member having an external thread that is bonded to the internal thread of the internal thread ring is inserted into the space behind the wall through the instrument mounting hole, and the external thread is screwed into the internal thread of the internal thread ring and The back end surface of the member is bonded to the vertical surface, and the device is fixed to the base member.

[0009] According to the wall mounting device mounting method and method, the inner screw ring is fixed to the back surface of the wall board.
Further, since the base member screwed to the inner screw ring is fixed to the vertical surface at the back end surface, the base member can be extremely firmly installed on the wall surface, and a device such as a grip bar can be extremely mounted on the wall surface. It can be installed with high mounting strength.

The inner screw ring has a slit having a circumferential width larger than the thickness of the wall board. Even if the inner screw ring has a diameter larger than the instrument mounting hole, the inner screw ring can easily pass through the instrument mounting hole. Can be arranged on the back side of the wall board.
