<P>PROBLEM TO BE SOLVED: To easily stop the door of a switchboard at an opening angle smaller than a predetermined angle. <P>SOLUTION: A hinge for the switchboard comprises a door folding part 7 around a door 6 covering a switchboard frame 5, a door bearing 3 is fitted inside of it, a frame bearing 2 is fitted to the frame 5 through a frame bearing fitting leg 1, and a shaft 4 connects the door bearing 3 to the frame bearing 3 for free revolution. The door folding part 7 hits the frame bearing fitting leg 1 when the door 6 is opened, to limit the opening angle of the door 6. An opening angle limiter 10 for narrowing the opening angle of the door 6 is inserted between the door folding part 7 and the frame bearing fitting leg 1. The opening angle limiter 10 inserts a bent part 11 between the door folding part 7 and the frame bearing fitting leg 1, wherein a part of the plate provided with a shaft hole into which the shaft 4 is inserted for free revolving is bent in the direction parallel to the shaft. <P>COPYRIGHT: (C)2004,JPO |
