摘要： PROBLEM TO BE SOLVED: To provide an electromagnetic contactor capable of enhancing a suction force for a movable iron core when exciting a coil even the coil is lengthened.SOLUTION: An electromagnetic contactor 10 includes: a fixed contact part 118a; a movable contact part 130; a movable supporter 131; and an electromagnet unit 200. The electromagnet unit 200 includes: a movable iron core 215 coupling the movable supporter 131 at one end thereof, for allowing an axis to face toward a direction along a driving direction of the movable supporter 131; a fixed iron core 203 disposed on the other end side of the movable iron core 215 in an axis direction and on the same axis of the iron core 215, extending to a direction alienated from the movable iron core 215 and an excitation coil 208 at least disposed on the outer peripheral side of the fixed iron core 203. On the end side of the movable iron core 215 of the fixed iron core 203, a bottom concavity 203b in cylindrical body to which the other end side of the movable iron core 215 can be inserted in a state when the fixed contact part 118a coming into contact with the movable contact part 130.

摘要： PROBLEM TO BE SOLVED: To provide an electromagnetic contactor that can prevent a movable contact from wobbling longitudinally when a contact mechanism is closed and opened.SOLUTION: An electromagnetic contactor 1 includes a contact mechanism CM having a pair of fixed contacts 11A, 11B arranged at a predetermined longitudinal interval, and a movable contact 12 arranged above the pair of fixed contacts 11A, 11B and capable of separable contact with the pair of fixed contacts 11A, 11B. The movable contact 12 is vertically movably arranged on a coupling shaft 37 fixed to a movable plunger 36, and is, at a longitudinal middle portion thereof, pressed by a downward loading force of a contact spring 16 to be held on the coupling shaft 37. The coupling shaft 37 is mounted with a plate spring member 20 extending longitudinally and having in the vicinities of both longitudinal outer ends a pair of loading force application portions 22a, 22b for applying a predetermined loading force downward to a pair of movable contact points 12d, 12e.
