Document Type and Number:
WIPO Patent Application WO/2021/049395
Kind Code:
A1
Abstract:
A solenoid (S1) is provided with: first and second stationary iron cores (5, 6) which are respectively on one end side and the other end side of a coil (4) in an axial direction; first and second movable iron cores (7, 8) which are respectively attracted toward the first and second stationary iron cores (5, 6) when current is passed through the coil (4) and which are located between the first and second stationary iron cores; a spring (9) which biases the first movable iron core (7) toward the second stationary iron core (6) side; and a plate spring (90) which restricts the movement of the first movable iron core (7) toward the second stationary iron core (6) side with respect to the second movable iron core (8), wherein the first movable iron core (7) is restricted from moving in a direction orthogonal to the axial direction of the coil (4) with respect to the first and second stationary iron cores (5, 6).
