PROBLEM TO BE SOLVED: To provide a mounting structure of a circuit breaker capable of reducing cost by reducing a mounting time of the circuit breaker, and reducing a dimension of a mounting board. SOLUTION: A fixture 3 is formed by folding a plate spring and includes an inclining part 3a for guiding a projection part 1b of the circuit breaker 1, a locking hole 3c for locking the projection part 1b of the circuit breaker 1, and an engaging claw 3d for engaging and fixing with the mounting plate 2. The mounting plate 2 is folded at end parts to form an upper plate 2c and a lower plate part 2e. An insertion hole 2d is pierced on the upper plate part 2c, and an engaging hole 2f is pierced on the lower plate part 2e. The fixture 3 is fixed by inserting a body part 3b in the insertion hole 2d, and engaging an engaging claw 3c with the engaging hole 2f. When the circuit breaker 1 is mounted on the mounting board 2, one of the projection parts is inserted in and engaged with an engaging hole 2b of an engaging piece 2a projected on the mounting board 2, the circuit breaker 1 is pushed in downward, and the other projection part 1b is locked to the locking hole 3c of the fixture 3 so that the circuit breaker 1 is fixed. |
