Claims

[Scope of utility model registration request]

A mutual locking device unit for electromagnetic contactors that locks a pair of electromagnetic contactors juxtaposed at opposite positions so that both cannot be turned on at the same time, the electromagnetic contactors being connected to the movable contact holding member of each of the electromagnetic contactors and facing each other. The electromagnetic contactor is arranged at a position that responds to the movement of the movable contactor holding member, and maintains slidable contact on the mutual contact surfaces, and is formed at the end of the contact surface in the sliding direction when both of the electromagnetic contactors are in the released state. a responsive member having a recess formed in a tapered surface; a movable round bar-shaped locking pin having an outer circumferential surface that maintains contact with the tapered surface in the recess formed by the responsive member; It includes a return spring that biases the locking pin toward the recess, and a pair of cases whose end surfaces of the peripheral wall are joined to each other, each of the pair of cases protruding inwardly from one side of the peripheral wall to receive the locking pin. A square column and a bottom have a coupling window for coupling the response member to the movable contact holding member, and a positioning protrusion on the outside of the bottom, and the response member, locking pin, and return spring are housed and integrated. A mutual locking device unit for electromagnetic contactors characterized by:
