Filed: 1998-07-06
Abstract: PROBLEM TO BE SOLVED: To reduce a height dimension in spite of a narrow structure to provide an excellent assembling characteristic by arranging a movable iron piece, in which one end is allowed to abut to an iron core while the other end is opposed to a yoke attachably/detachably, and a hinge spring, which is elastically deformed so as to bring its one end part into pressure contact with the iron core, in a housing recess of a first base. SOLUTION: A hinge spring 3 presses a movable iron piece 4 by means of an elastic arm part, and in the movable iron piece 4, a locking recess preventing it from coming off upward is formed. When current conduction in a coil so as to magnetize a coil block 2, an upper end of the movable iron piece 4 is attracted to an attraction part in a yoke 49 so as to be turned clockwise around the lower end part. In this way, a movable contact piece 9 is driven via a card 54, and the movable contact 9a is closed to a fixed contact 10a. When current conduction to the coil is stopped and the coil block 2 is demagnetized, attraction force disappears, so that the movable contact piece 9 is returned to its original position by its elasticity, and the movable contact 9a is separated from the fixed contact 10a.
