I am wearing it. The remote control block 23 provided in the inner main body 11 is divided into two printed boards, a light receiving section 24 and a control section 25, and an insulating sheet 26 is interposed between the inner main body 11 and the printed circuit board. It is attached in two steps. The lower surface of the inner main body 11 is configured so that a control signal by infrared rays can reach the light receiving unit 24.

A pair of terminal blocks 6 are mounted on the upper surface of the inner main body 11 via mounting brackets 27. A power cable 7 such as a VVF cable is connected to each of the pair of terminal blocks 6. One terminal block 6 of the pair of terminal blocks 6 is connected to a power supply line 7 from a commercial power supply, while the other terminal block 6 is connected to a lighting fixture controlled by a remote control adapter which is the electric appliance 4. To the power line 7.

On the lower surface of the inner body 11, the mounting screws of the mounting part 21 of the outer body 10
A so-called darling hole 28 is formed corresponding to 22. After inserting the head of the mounting screw 22 through the large-diameter portion of the daruma hole 28, the inner main body 11 is rotated, and the head of the mounting screw 22 is engaged with the small-diameter portion of the daruma hole 28. 22 is attached to the outer body 10 by tightening. And at this time,
The terminal block 6 attached to the inner body 11 has an opening 14 in the outer body 10.
From above.

The frame body 12 is formed by forming a substantially cylindrical rising portion 30 substantially at the center of the annular width of the frame main body 29 on the upper surface of the substantially annular frame main body 29. In the frame 12, the mounting spring 19 attached to the rising portion 30 is engaged with the spring locking piece 20 of the outer body 10, the rising portion 30 is inserted into the outer body 10, and the outer peripheral edge of the frame main body 29 is It is suspended from the outer body 10 in a state of being in contact with the ceiling 2.
