Reference numerals 10 and 10a are holes provided close to the other end of the cutout portions 8 and 8a. Reference numeral 11 denotes a window hole provided in the flat surface of the bracket 5, and a stopper 12 pressed inward is formed at the end of the window hole. Reference numeral 13 denotes a screw hole provided in the flat portion 6 for mounting an electrical device.

Reference numeral 20 denotes a fixing member integrally molded from a synthetic resin material, and as shown in FIG. 3, protrusions 22, 22a are provided at both ends of a cylindrical base 21 at positions eccentric from the center of the cylinder. There is. 23 is the base 21
The locking arm extends from the locking arm to one side, and has a fitting portion 24 formed near the tip and a groove 25 for providing elasticity. 26 is a locking groove provided on the distal end side of the fitting portion 24, and 27 is a stepped portion. 28
is a hook portion protruding from the base portion 21 on the opposite side of the locking arm 23. Note that 29 and 29a are the base 2
Although this groove is provided to impart elasticity to the groove 1, it may be omitted.

Next, the operation of the present invention will be explained. First, in order to attach the base 21 of the fixing member 20 to the bracket 5,
The locking arm 23 of the fixing member 20 is inserted through the window hole 11, and the projections 22, 22a are fitted into the holes 10, 10a. Thereby, the fixing member 20 is rotatably attached to the bracket 5. FIG. 4 shows a state in which the fixing member 20 is rotated clockwise to stand up, and the stepped portion 27 is in contact with the lower edge of the window hole 11, and the lower edge of the base 21 is connected to the cutout of the bracket 5. It is located at approximately the same position as the edge portions of portions 8 and 8a.

In this state, as shown in FIG.
