PURPOSE:To reduce the number of screws to be used and to improve mounting operability by providing a connecting protrusion to be connected to a mounting frame on the rear face of a flush plate. CONSTITUTION:A switch 25 is engaged with a protrusion hole 30, and the connecting protrusion 12 of a flush plate 1 is inserted to the connecting hole 13 of a mounting frame 3 to be temporarily clamped. A suppressing plate 14 engaged with both ends of the plate 1 is engaged with the threaded holes of a buried box by inserting screws 33 to the mounting holes 17 of the frame 3, and the frame 3 and the plate 1 are mounted on the box. The plate 14 is secured to both the right and left recess steps 9 of the plate 1. Thus, since the protrusion is provided on the rear face of the plate 1, it can be temporarily clamped at the frame 3, the plate 1 and the frame 3 can be simultaneously mounted on a wall face or the like, and the number of screws to be used is reduced to improve the mounting operability, thereby facilitating positioning of an implement and the plate 1. |
