Claims (1)

[Scope of Claim for Utility Model Registration] A pressure fluid supply port, an output port, a valve seat in a passage that communicates both ports, a fixed iron core disposed opposite to the valve seat, and a coil that is energized to cause the fixed iron core to A movable iron core that is attracted, a valve element that opens and closes the valve seat that is slidably inserted into the valve element sliding part of the movable iron core, an auxiliary spring that biases the valve element toward the valve seat, and a movable iron core. In an electromagnetic switching valve equipped with a return spring that biases toward the valve seat, and in which the biasing force of the return spring is greater than the biasing force of the auxiliary spring, the valve body is prevented from coming off toward the valve seat side of the movable iron core. An electromagnetic switching valve characterized by comprising: a locking member made of synthetic resin having a locking shoulder portion that locks.
