The disclosure describes an air circuit breaker having a bounce preventive device which is provided on a direction changing lever (43) interposed between the link mechanism (47) to drive a contact opening and closing mechanism (69) for closure of the contact (54,55) and this contact opening and closing mechanism, so as to prevent the bouncing phenomenon to occur at the time of the OFF-operation, thereby making it possible to secure accurate circuit breaking action. |
