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.

Abstract: A solenoid includes a first fixed iron core and a second fixed iron core located on one axial end side and the other axial end side of a coil, a first movable member and a second movable member located between those fixed iron cores and configured to be attracted to the first fixed iron core and the second fixed iron core, respectively, by energization of the coil, a spring configured to bias the first movable member toward the second fixed iron core, and a first regulating portion made from a non-magnetic material, provided integrally with the first movable member or the second movable member, and configured to regulate movement of the first movable member toward the second fixed iron core with respect to the second movable member.

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.
