<P>PROBLEM TO BE SOLVED: To provide a solenoid that has a structure capable of increasing the stability of thrust and extending the length of a control stroke range. <P>SOLUTION: By virtue of a thrust adjustment portion 21 at a tip end of a cylindrical portion 25 of a stationary pole 20, a solenoid 10 can reduce change in thrust when a coil 38 is energized to attractively slide a movable pole 40 to the stationary pole 20, and can have a longer control stroke range than a prior art solenoid having a similar structure. A uniform thickness throughout the thrust adjustment portion 21 allows the stationary pole 20 to be formed easily by cutting or the like. <P>COPYRIGHT: (C)2012,JPO&INPIT |
