A locking portion (13) is provided to lock an open/close cover (15) to a fuse unit (5) or a cover main body (9) assembled to the fuse unit (5) in a state where the open/close cover (15) is closed. The open/close cover (15) is openably and closably connected to the cover main body (9), and includes first and second side walls (17, 19) respectively on both end sides in an orthogonal direction orthogonal to an opening/closing direction and extending in the opening/closing direction. The locking portion (13) includes a locking protrusion (21) provided in the first side wall (17) deformable in the orthogonal direction, and a mating locking protrusion (23) provided in the fuse unit (5) or the cover main body (9) and facing the first side wall (17). |
