An armature and a valve member reciprocally slide in a slide hole of a valve body. The valve member seats on or lifts off from a valve seat to close or open a valve hole. One of the armature and the valve member includes an engaging concave surface. A connector is formed separately from the armature and the valve member, or is formed integrally with the other one of the armature and the valve member. The connector includes an engaging convex surface that is in contact with the engaging concave surface of the one of the armature and the valve member.
