[Scope of Claim for Utility Model Registration] A small diameter flow path of a certain length is formed in the flow path with a valve seat at one end and a retaining wall at the other end, and in this small diameter flow path, the above retaining wall side is A valve body having an axial flow path that is open and closed on the valve seat side, and a radial flow path that communicates with the axial flow path is slidably inserted, and the valve body is slidably inserted into the valve body on the retaining wall side. A spring seat protrudes outward at the end of the valve body, and an annular groove is formed on the outer periphery of the end on the valve seat side, and an O-ring is fitted into the annular groove of the valve body, and the spring seat and a retaining wall are formed. A check valve characterized in that a spring means is interposed between the O-ring and the valve seat to bring the O-ring into elastic contact with the valve seat.
