Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support, a wiring device body, and a wiring device.

[0002]

2. Description of the Related Art Conventionally, wiring devices such as switches and outlets are mounted on a support, which is a standardized mounting frame, and the wiring is pulled out from a wiring box embedded in a wall, which is a commercial product. After connecting to the wiring equipment body, screw the support to the wiring box,
It is installed on the wall by attaching a decorative plate that covers the support and the like with the working portion of the wiring device exposed. In addition, the "acting part" of the wiring device means a part where a person exerts an action when the wiring device is attached to a wall surface, for example, in the case of a switch, a switch operation part and an outlet. If so, the plug insertion portion corresponds to the "action portion".

Further, in recent years, a wide switch type (hereinafter referred to as "wide type") wiring device, which can easily perform a switching operation and can more easily recognize a discrimination of an operating portion, has become widespread.

This wide type wiring device is mounted by mounting the wiring device main body in a state in which no action portion is provided on a support which is a standardized mounting frame, and from a wiring box embedded in a wall surface which is a commercial product. After connecting the drawn wiring to the wiring device body, the support is screwed to the wiring box, the adapter is arranged on this support, and the decorative plate covering the support and the like is attached to the adapter. Then, the switch cover, which is an action portion, is directly attached to the wiring device body so as to close the opening of the decorative plate.

[0005]

However, in the wide type wiring device, the opening of the decorative plate is formed to be larger than the opening of the support. Therefore, when three wiring device bodies are connected to the plate in series. When three switch covers are mounted, it is not always possible to match the center of the surface of the wiring device body where the switch cover is mounted with the center of the switch cover, so it is necessary to install multiple switch covers properly. There was a problem that the installation work to install was very complicated.
