PURPOSE: To attach and detach an electrical junction box easily. CONSTITUTION: Rotary plates 3 which have knobs 12 are respectively attached to a pair of facing attachment plates 2 with shafts so as to rotate freely. Pairs of pins 9 protrude on respective inner surfaces of the rotary plates 3. Slots 14 are formed on both the left and right end surfaces 7 of an electrical junction box 1. Each slot 14 is composed of a straight part 15 which has an entrance 17 on its one end and two circular arc bent parts 16 continuous with the straight part 15. After the rotary plates 3 are supported by the shafts of the attachment plates 2, the electrical junction box 1 are inserted while the pins 9 are made to enter relatively the straight parts 15 of the slots 14. If the rotary plates 3 are turned after that, the pins 9 are turned into the respective bent parts 16 and retained to hold the electrical junction box 1 in an undrawable state. In order to detach the electrical junction box 1, the rotary plates 3 are turned in the opposite directions to return both pins 9 into the straight parts 15 of the slots 14 and the electrical junction box 1 are drawn out. |
