Claims

[Scope of utility model registration request]

A movable core that is attracted to the fixed core in response to an overcurrent flowing through the breaker, a connecting rod that has one end connected to the movable core and a nut screwed to the other end, and a connecting rod that engages with the nut and is engaged with the movable core. a trip bar that rotates when the breaker is drawn to the fixed core and trips the breaker; an adjustment screw that is supported by a support and presses the movable core to adjust the distance between the movable core and the fixed core; A circuit breaker comprising an elastic material provided at a contact portion of an adjustment screw with the movable iron core.
