In the solenoid valve that opens, a portion of the valve seat that the plunger contacts is movable, the valve seat movable portion is movably supported, and the valve seat movable portion is separated from the center post between the valve seat movable portion and the center post. A solenoid valve characterized by being equipped with a second spring that biases in a direction.
