Abstract

A solenoid valve is equipped with a check valve and a filter member, which is configured to suppress entry of foreign matter contained in working fluid by means of a filter provided at an opening having an outer periphery surrounded by a frame. The check valve is arranged downstream of the filter member with respect to a free flow direction of the working fluid. A part of the check valve is structured integrally with the frame, and the check valve is configured to open and close by movement of the outer peripheral surface of the check valve out of and into abutted-engagement with the inner peripheral surface of the frame, thereby restricting back-flow of the working fluid.
