Claims

[Scope of utility model registration request]

A base equipped with a main circuit terminal and a movable contact that moves the movable contact that opens and closes the terminal, and a movable iron core that is slidably attached to the base while being biased in one direction by a tripping spring. A supporting crossbar, a rail plate having a pair of rail parts and fixedly disposed in an opening provided at the bottom of the base, a fixed iron core that faces the movable iron core and attracts the movable iron core, and the fixed iron core. an operating coil that is combined with the operating coil to generate a predetermined excitation force, and is integrally and detachably attached to the base along the rail section, each rail section of the rail plate. The spring holder has a plate integrally molded with the rail plate in the width direction of the Renil plate, and the spring holder has a plate that supports one end of the tripping spring. , the width between the plate ends of both spring supports is set to be approximately the same as the width between the facing walls of the base,
An electromagnetic contactor characterized in that the inward deflection of the base is restricted by the plate ends of both spring supports.
