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, 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, and a communication passage that causes the first fixed iron core side of the second movable iron core to communicate with the second fixed iron core side.
