PURPOSE: To provide a method for fixing a holding fixture for holding a back spring, which is held by a movable contact support connected to a movable iron core under the compression condition at the time of electrifying a coil and which drives the movable contact support in the interrupting direction at the time of stopping the electrifying, between the movable contact support and the holding fixture to the inside of an electromagnetic contactor main body case without requiring a hook hole and a recessed part on the case wall surface.
CONSTITUTION: A holding fixture is formed into the L-shape, and one side thereof is used as a seat surface of a back spring, and the other side and a case are formed so that the friction force, which can hold the back spring under the compressed condition, is generated between the other side and the case. Practically, a case 14 is formed with two surfaces 14c, 14d opposite to each other and in parallel with the case wall surface, and a flat plate surface forming the other side 16b is hollowed like U and a tongue piece 16a is pushed out. The other side 16b is pressed-in between the opposite two surfaces 14c, 14d of the case 14 with the tongue piece 16a, or the other side 16b is folded toward the bending direction of the L-shape and pressed-in between the opposite two surfaces 14c, 14d of the case 14.
