<P>PROBLEM TO BE SOLVED: To provide a solenoid in which, at the same time, the winding number of coils of an auxiliary spring can be sufficiently secured, and miniaturization of a device can be achieved. <P>SOLUTION: In the solenoid 1, a plunger 4 is driven by magnetic field generated in a coil 12, and a shaft 5 coupled to this plunger 4 moves in a shaft direction. This solenoid includes: a coil-shaped auxiliary spring 66 by which the shaft 5 is energized in the shaft direction; and an adjuster 80 by which a spring force of this auxiliary spring 66 is adjusted. An auxiliary spring tip housing recess 57 is formed to a shaft 5 which houses the tip of the auxiliary spring 66 in the shaft. <P>COPYRIGHT: (C)2012,JPO&INPIT |
