DETAILED DESCRIPTION OF THE INVENTION OBJECTS OF THE INVENTION (Field of Industrial Application) The present invention relates to electrical appliances such as recessed boxes or electrical outlets that are mounted on walls or the like.

(Prior Art) Conventionally, electrical appliance bodies, such as switches and outlets, which are installed in recessed boxes that are generally embedded and fixed in walls, etc., have been attached to the mounting frame with several screws. A structure is adopted in which a frame body called a fludge plate, which has a window hole that exposes the front surface of the instrument body, is attached using another screw.

In addition, recently, electric appliances that give a sense of luxury, such as switches that can be mounted on the frame, have been fitted with large panels on the front of the appliance body, for example, to improve operability. It has been proposed that a front plate section larger than the projected area of the front side, for example, a removable operating part be attached to the main body of the electric appliance (Puta I structure), is used to attach the main body of the electric appliance to the mounting frame. Installation: Attach a frame body having a window hole larger than the projected surface area of the electrical appliance main body to the mounting frame so as to cover the mounting frame, and in this state, attach the front surface of the electrical appliance body that is exposed through the window hole of the frame body. A structure is adopted in which a front plate portion larger than the front projected area of the electric appliance body 2 that closes this window hole is attached to the front surface of the electric appliance body.However, in such a structure, the front plate portion is attached to one hole in the frame. Because of its size, there is almost no gap between the front panel and the window hole, and the front panel is firmly attached to prevent it from accidentally coming off the appliance. When removing the front plate 5, prying the front plate with a tool such as a screwdriver may cause damage or deformation of the front plate.Therefore, the frame is divided into two parts, and the first A structure in which a recessed step is formed at the periphery of the opening of the frame, and a second frame having a window hole through which the front plate of the appliance main body is formed is attached to the recessed step. electrical appliances have been proposed.
