PURPOSE:To facilitate the assembling operation by projecting an actuator head, provided atop of a plunger, from an upper plate, supporting the lower end by a spring in a pipe made of a nonmagnetic material, and driving the plunger by a solenoid coil wound around the outer periphery of the pipe. CONSTITUTION:The pipe 25 made of the nonmagnetic material is arranged on the reverse surface side of the upper plate 21 capable of radiating heat to the outside and the plunger 26 is provided in the pipe 25 in a vertically rotatable state; and the actuator head 27 provided atop of the plunger 26 is projected from the upper plate 21, the lower end of the plunger 26 is supported elastically while mounted on the spring 29 arranged in the pipe 25, and the solenoid coil 23 is wound around the outer periphery of the pipe 25 and fed with electricity from outside to produce a magnetic field, thereby driving the plunger 26 toward the upper plate 21. Consequently, the assembling operation is facilitated. |
