Claims

[Scope of utility model registration request]

A link mechanism is linked to the opening/closing part that is biased in the opening direction by the biasing member, and a plunger of a solenoid is linked to the link mechanism so as to be in pressure contact with the link mechanism, and when the solenoid is energized, the link mechanism is activated by the plunger. A trip mechanism including a trip coil is linked to the link mechanism, and is arranged in a position that allows the plunger of the solenoid to be pressed against the link mechanism when the link mechanism is not tripped. and a driven member disposed at a position that disables the pressing drive of the plunger and allows the biasing release drive of the biasing member at the time of tripping.
