PROBLEM TO BE SOLVED: To provide a distribution board in which a receiver blade of a circuit breaker is hard to be deformed and heat generation can be suppressed when a conducting bar is inserted and connected. SOLUTION: In this circuit breaker 2, an engaging part 58 at a tip of an elastic protruding segment 47 of an engaging member 48 gets over a part 57 to be engaged, and is arranged on a fixing base 7 in the state that the part 57 to be engaged is engaged with the engaging part 58. Consequently, it is regulated that the breaker 2 moves in the outward direction. In the circuit breaker 2, an anchoring part 39 installed in a protrusion 54 fitted in a recess 36 on the breaker side surface from below is inserted in a part 53 to be anchored. A fitting recessed part 39a on the lower surface of the anchoring part 39 is fitted in a fitting protruding part 53a installed on the lower surface of the part 53 to be anchored. As a result, movement in the upper direction is regulated. |
