おける復帰ばね保持構造。 Inside the case, it is integrated with a movable core that has a magnetic pole surface that approaches and separates perpendicularly to the magnetic pole surface of the electromagnet fixed core that is fixed on one side of the case, and supports the movable contact, and the direction of the surface is movable. A plate-shaped contact support perpendicular to the moving direction of the iron core is pressed against another surface of the case when the electromagnetic coil is not energized to maintain a predetermined distance between the magnetic pole faces of the fixed iron core and the movable iron core.
A return spring holding structure for an electromagnetic contactor that holds a return spring formed as a compression coil spring between a fixed core side fixing member and the contact support, wherein the return spring is attached to a spring wire at one end of the coil shaft. The contact support is formed with a linear mooring portion extending outward from the coil, and the peripheral wall is cut into a slit shape in the axial direction so that the return spring can be inserted from the mooring portion side to the axis of the return spring coil. A protrusion is formed with a guide hole that can be recessed in the same direction and a notch cut perpendicularly to the axis of the guide hole on the bottom side of the guide hole of this slit, and the return spring is inserted into the guide hole from the mooring part side. An electromagnetic device characterized in that a protrusion is formed on the surface of the contact support to elastically deform a portion of the mooring portion that extends outward from the protrusion when the mooring portion is inserted into the notch. Return spring holding structure in contactor.
