Note that the same reference numerals in each figure indicate the same or corresponding parts.

Claims (1)

[Scope of Claim for Utility Model Registration] (1) A stator fixed to a housing by a fixing means, a fixed contact provided on the stator, a movable element driven by a tripping device, and a movable element on the movable element. a movable contact that is connected to and separated from the fixed contact by a movable element; and a movable contact that is screwed to the stator by a screwing means provided at a position that does not interfere with the fixing means, and that there is a gap between the fixed contact and the movable contact. A circuit breaker characterized by comprising: a magnetic arc guiding member for guiding a generated arc to an arc extinguishing means. (2) The stator is folded so that the folded outer surface is formed almost perpendicular to the arc firing direction, and the folded inner dimension is wider than the thickness of the arc guiding member. , the arc induction member is provided on the folded outer surface of the stator, and the arc induction member is fixed to the folded inner surface of the stator by a bolt screwed into the folded outer surface of the stator. A circuit breaker according to claim 1 of the patent registration claim.
