PURPOSE: A moving contact perturbation structure is provided to make a moving contact plate and a connection plate maintained at a conduction state without using a compression spring with divided connection plates coupled by one bolt. CONSTITUTION: A connection base is divided into the first and second connection bases(130,131) having a bolt connection hole formed on a lower part. A bolt is connected with the bolt connection hole via a case with the bolt connection holes of the first and second connection bases(130,131) being laid over. A moving contact base(132) is fitted between the first and second connection bases to selectively contact with the fixing contact, so as to be contact with the first and second connection bases(130,131) at a conductible state. Both ends of a hinge pin is seized by a holder in a breaker with the hinge pin being fitted via hinge connection holes of the first and second connection bases(130,131) and the moving contact base(132).
