The present article is an electromagnetic valve used for switching communication and blockage of pressure fluid. The electromagnetic valve includes: a body; solenoid coil portion projected from one end side of the body; a U-shaped flame continuously formed on the one end side of the body to surround the solenoid coil portion; and a rectangular connector portion continuously formed on the one end side of the flame (See Reference drawings 1 and 2 ). On the bottom surface of the body, a gasket is provided and two pressure fluid inlet/outlet ports are formed along the longitudinal direction. Inside the body and the solenoid coil portion, a not illustrated valve body for switching communication and blockage between the two pressure fluid inlet/outlet ports; a not illustrated plunger (movable iron core) attached to a tip of the valve body; and a not illustrated solenoid coil are housed. Magnetic plates are provided on the top and bottom surfaces to apply electromagnetic force on the plunger. Not illustrated guide grooves having a semi-circular cross section are formed on the front and rear surfaces of the body to guide mounting screws. Lead wires are provided on the connector portion to feed electricity and receive control signals. When using, the present article is mounted on a desired position using not illustrated screws. Then, a pressure fluid supply source is connected to one of the pressure fluid inlet/outlet ports, and a fluid pressure device is connected to the other of the pressure fluid inlet/outlet ports to supply the pressure fluid to the fluid pressure device. When the electricity is supplied and shut off via the lead wires, the plunger moves in the longitudinal direction in the solenoid coil portion and the body by the electromagnetic force generated from the solenoid coil. By the movement of the plunger, the valve body is moved in the body. Thus, the communication and blockage between the two pressure fluid inlet/outlet ports are switched.
