To improve appearance by reducing the protrusion of the edge of a door body from the side surface of a box body when opening the door body, so as to reduce the gap between the side surface and wall surface of the box body.

This hinge 4 of the box body 1 for housing the electric equipment includes: a box-body-side hinge 5 which is provided outside the opening frame 2a of the box body 2 and which has a tubular portion 5a; a door-body-side hinge 6 which is provided in a position to face both end surfaces of the box-body-side hinge 5 of the door body 3, and which has a plate-like portion 6a parallel to both the end surfaces of the box-body-side hinge 5; and a hinge pin 7 which is inserted through the insertion hole 5b of the tubular portion 5a of the box-body-side hinge 5 and an insertion hole 6b formed in the plate-like portion 6a of the door-body-side hinge 6. A cutout 6e is formed in a fixed-plate 6cb which abuts on the inside of the door body 3 so as to fix the door-body-side hinge 6 to the door body 3, and thus, the tubular portion 5a of the box-body-side hinge 5 can be fitted into the cutout 6e of the door-body-side hinge 6 when the box-body-side hinge 5 and the door-body-side hinge 6 are attached in a hinged manner.
