<p>PROBLEM TO BE SOLVED: To suppress the hitting sound which is produced when a mobile core approaches a fixed core side, while the magnetic fixture of the mobile core to the fixed core is avoided, and in addition, to improve the responsiveness on the side of the mobile core which is separated from the fixed core in a solenoid device which is provided with the fixed core, the mobile core which is movable towards and away from the fixed core, and a coil which exhibits an electromagnetic force that attracts the mobile core to the fixed core side. SOLUTION: A spacer 501 which is sandwiched between a mobile core 31 and a fixed core 30 when the mobile 31 moves to the fixed core 30 side, exhibits a repulsive force that separates the mobile core 31 from the fixed core 30, when the spacer 501 is sandwiched between the mobile and fixed cores 31 and 30, and is made of a nonmagnetic material interposed between the cores 30 and 31.</p> |
