Abstract
A solenoid includes a first fixed iron core and a second fixed iron core located on a first end side and a second end side of an axial direction of a coil, a first movable iron core and a second movable iron core located therebetween and attracted by the first fixed iron core and the second fixed iron core by passage of current through the coil, respectively, a spring that biases the first movable iron core to the second fixed iron core side, and a leaf spring that regulates movement of the first movable iron core to the second fixed iron core side with respect to the second movable iron core. The movement of the first movable iron core in a direction orthogonal to the axial direction of the coil with respect to the first fixed iron core and the second fixed iron core is regulated.
