AbstractA three-way electromagnetic valve provided with a valve body, a movable member slidably disposed in the valve body, an actuator for driving the movable member, an opening-closing mechanism provided in an internal passage formed in the movable member. A clearance reducing portion is formed to reduce a gap created by a pressurized fluid entering the slide section or by the force of fastening and fixing the valve body, thereby limiting the leakage of the pressurized fluid.
