Claims

[Scope of utility model registration request]

A base equipped with a movable core that moves the main circuit terminal and a movable contact that opens and closes the terminal, a rail plate that is fixedly disposed in an opening provided at the bottom of the base, and a movable core that moves opposite to the movable core. The base has a fixed iron core that attracts the iron core, a guide member having a rail hook provided at both ends of the fixed iron core and engaging with the rail plate, and an operating coil that is combined with the fixed iron core to generate a predetermined excitation force. a coil holding frame that is inserted and fixed into an opening provided on a side of the coil holding frame;
a locking means for removably engaging between the coil holding frame and the rail plate; an asymmetrical engagement hole is provided in the center of the guide member; A retaining protrusion corresponding to the retaining hole is provided, and the guide member is permanently attached to the coil holding frame in a forward direction by engagement of the engaging protrusion and the engaging hole, and the fixed iron core is attached to the coil holding frame. An electromagnetic contactor characterized in that the rail hook of the guide member engages with the rail plate without wobbling while being held.
