PROBLEM TO BE SOLVED: To reinforce a keyway and prevent breakage by providing a first keyway in a handle in the side surface direction of a door body for covering a casing's opening and forming the handle portion into a box shape. SOLUTION: This circuit beaker storing casing 1 comprises a casing body 2 and a door body 3, and the door body 3 is hinged with the casing body 2 such that an opening 4 in the casing body 2 can be covered. A handle 5 having a first keyway 7 is provided on a side surface of the door body 3. In addition, the casing body 2 is provided with a projection 6 having a second keyway 8 in the facing part of the first keyway 7. A circuit breaker 9 is placed on the casing body 2 of the circuit breaker storing casing 1, the opening 4 in the casing body 2 is covered by rotating the door body 3 hinged to the casing body 2, and the first keyway 7 provided in the handle 5 is faced to the second keyway 8 provided in the projection 6. A lock 10 is inserted into the first and second keyways 7, 8 for locking. Thus, the keyways are not seen from the view of the front face of the circuit beaker storing casing 1 not to lose a design property. |
