Claims

[Scope of utility model registration request]

The top surface of the instrument case is a mounting plate with a through hole, and the instrument case is fixed by tightening a nut from inside the case onto a bolt that protrudes from the fixed side and is inserted into the through hole. In the mounting structure of the lighting equipment case, the through hole is opened as a hole with a larger diameter than the nut, and a temporary fixing plate is provided on the lower surface of the mounting plate portion along the lower surface. The temporary fixing plate is provided so that it can be moved by the bolt, and by the same movement, the temporary fixing plate can close a part of the through hole, and the bolt is passed through the through hole with the nut screwed in advance. The temporary fixing plate moves and enters between the nut and the attachment part on the outer periphery of the bolt, thereby preventing the instrument case from falling downward, and in this restricted state, tightening the nut, the instrument A mounting structure for a lighting equipment case, characterized in that the case is fixed.
