Zusammenfassung:	An electromagnetic valve has a valve housing; a valve body disposed inside the valve housing and movable in a reciprocating manner; an urging member configured to urge the valve body in one direction; and a drive device which is connected to the valve housing and applies a drive force to the valve body. A drive rod of the drive device includes a guide portion which faces an inner peripheral surface of a fixed iron core such that a movement of the drive rod is guided in an axial direction and a groove portion which is recessed in an inward radial direction from the guide portion and the groove portion is continuously formed from an inside of the valve housing to an inside of a movable iron core.
