PROBLEM TO BE SOLVED: To prevent an erroneous operation of a circuit breaker while restricting an increase of a space occupied by a circuit breaker in a casing.SOLUTION: Comparing the preferred embodiment of the present invention with the prior art shown in Fig.5 in reference to a space of a circuit breaker 5 occupies in a casing 1 (a volume of a storing cavity 10) shows that the space can be reduced in the preferred embodiment by an amount in which the circuit breaker 5 is inclined to cause the lower part of a case 50 to move more forward than its upper part. That is, the preferred embodiment has a holding member 6 for holding the case 50 of the circuit breaker 5 while being inclined in such a way that an angle &thetas; formed by a normal line direction, so that it is possible to prevent an erroneous operation of the circuit breaker 5 while restricting an increase of space occupied by the circuit breaker 5 within the casing 1. |
