Claims

[Scope of utility model registration request]

A fixed contact fixed in a case, a movable contact rotatably supported in the case and moving toward and away from the fixed contact by rotation, and a tripping device that detects an overcurrent. A latch mechanism has a catch that rotates when the latch is released, and first and second links rotatably connected by a connecting pin, and the first and second links are rotated by a toggle action in response to the release of the latch. a toggle link mechanism that bends a second link and rotates the movable contact so as to separate from the fixed contact; and a stopper member disposed within the case; The stopper member includes a first holding portion that is formed by bending a plate material and maintains the tension state of the first and second links when the fixed contact and the movable contact come into contact, and the toggle link mechanism. a first regulating part that regulates the rotation of the catch during the toggle action; a second regulating part that regulates the rotation of the movable contact during the toggle action;
and a second holding portion that prevents rotation of the second link in the extension direction.
