    • PROBLEM TO BE SOLVED: To prevent a planar part of a valve member from being inclined to a valve seat due to an axial displacement of a valve member and a valve hole while slidably engaging an armature with the valve member in an solenoid valve.
      SOLUTION: This solenoid valve comprises a valve body 4, on which a slide hole 41 is formed, an armature 3 which can reciprocate in the slide hole 41, a valve seat 22, on which a valve hole 23 is formed, a valve member 31 which reciprocates in the slide hole 41 in corporation with the armature 3 and has a planar part 311 seated on the valve seat 22, separated from the valve seat 22, and opening/closing the valve hole 23, and slide parts 302, 312, 32 which are interposed between the armature 3 and the valve member 31, slidably engage the armature 3 and the valve member 31 with each other, and has curved concave parts 302, 312 and a curved convex part 32 slidably contacting the concave parts 302, 312.
