Abstract

PURPOSE:To reduce the attracting force of an electromagnet by providing a compression coil spring for urging a movable iron piece mounted in hinge shape at a yoke toward the yoke and utilizing the partial pressure of the coil spring when the movable iron piece is attracted to a stationary iron core. CONSTITUTION:When a coil 4 is energized, a movable iron piece 1 is attracted to a direction A to alter the positional relationship between the movable iron piece 1 and the coil spring 14. When the movable iron piece 1 is allowed to contact with a stationary iron core 6, strength of the coil spring 14 acts also the movable iron piece 2 toward a direction of the yoke 2 to aid the magnetical coupling between the yoke 2 and the movable iron piece 1.
