Abstract
A solenoid valve includes a solenoid including a guide, a mover that moves in an axial direction radially inside the guide, a yoke made of a magnetic material and disposed on one axial side of the mover, a magnet on one axial side of the yoke, an elastic body that applies an elastic force to the mover in the direction away from the magnet, a cover made of a magnetic material, a pin which moves as the mover moves, and a valve that is opened and closed as the mover and the pin move. The cover includes a cylinder surrounding the radial outside of the solenoid, a first wall on the other axial side of the solenoid, and a second wall that covers one axial side of the magnet.
