Claims (1)

[Scope of Claim for Utility Model Registration] 1. A fixing hole provided in the longitudinal center of a fixed core of an electromagnet that drives a movable contact, with both ends elastically supported by a fixed core mounting plate, and a large diameter hole in the center. An electromagnetic contactor with a fixed core holding structure into which a pin with a protrusion is inserted. 2. A utility model registration claim in which the fixing hole provided in the fixed iron core is an elongated hole that is long in the electromagnet attraction direction, and the cross-sectional shape of the protruding portion of the pin is an ellipse that is longer than the short axis and shorter than the long axis of the elongated hole. The electromagnetic contactor according to item 1.
