Claims

[Scope of utility model registration request]

A mounting hole is provided on both sides in the width direction of the arc extinguishing chamber case and consists of a large diameter part and a small diameter part along the wall surface, and a long hole and an engagement hole that communicate with the mounting hole are provided on the joint surface. a main body case provided with a guide hole that intersects with the engagement hole and penetrates from the side wall to the inner wall; and at least one side that is slidably guided in the vertical direction within the main body case and coincides with the guide hole when the contact is in an open state. a movable contact support having a recess provided therein, and a locking portion that penetrates the mounting hole and the elongated hole via a head having a groove at the top and a coil spring and engages with the top side of the guide hole at its tip. a fixed shaft provided with a tongue; a tongue piece that is movably guided to at least one side of the guide hole and elastically engages with the engagement hole when the arc extinguishing chamber case is installed; and a tongue piece that locks the fixed shaft. 1. A movable contact support lock device for an electromagnetic contactor, comprising a lock piece which is a lock piece that engages with the arc extinguishing chamber case and fits into the recess by twisting as the arc extinguishing chamber case is removed.
