摘要： First fitting portions (9a and 9b) and second fitting portions (9c and 9d) are provided in a hook shape on the bottom (3a) of a housing so as to face each other. The first fitting portions are fitted to one rail edge (2a) of a rail (2) in the width direction and the second fitting portions are fitted to the other rail edge (2b) of the rail. A linear spring (10) that is bent in a mountain shape is provided on the bottom of the housing. The linear spring comes into contact with the end surface of the one rail edge to which the first fitting portions are fitted and is elastically deformed such that the inclination angle of the maintain is reduced. The urging force of the linear spring is applied to the rail such that the other rail edge is pressed by the second fitting portions.

摘要： There is provided an electromagnetic contactor such that it is possible to reduce the energizing current flowing to a coil, and to reduce the overall size. An electromagnet unit that drives a movable contact disposed so as to be connectable to and detachable from fixed contacts includes at least a movable plunger biased by a return spring, a coil (208) that enables the movable plunger to move, and a ring-form permanent magnet, magnetized in the direction in which the movable plunger is movable, disposed and fixed so as to enclose a peripheral flange portion formed on the movable plunger. A drive circuit (300) that drives the coil (208) includes a power source that supplies power to the coil (208), a pulse drive circuit (305) that outputs and supplies to the coil (208) an engage pulse that causes an operation suctioning the movable plunger and a hold pulse that, when the movable plunger is subjected to a suctioning operation by the engage pulse, maintains the suctioning operation, and a flywheel circuit (310), (320) having a semiconductor switching element (Tr2) connected in parallel to the coil (208).
