In an electromagnetic valve, a maximum distance between a movable core and a fixed core is set to be larger than a movable stroke of a movable rod moving together with the movable core. Therefore, a movable stroke of the movable core is set by a movable stroke of the movable rod, and the movable core always does not contact the fixed core. Accordingly, a vibration of the fixed core can be restricted and noise caused in the electromagnetic valve can be reduced. Further, because the movable core is movable without having an unnecessary moving stroke, a responsive performance of the electromagnetic valve relative to an electrical switching can be improved.
