Each valve body includes a valve body having a valve chamber, a cap that closes an opening at one end of the valve body, and a valve body integrally formed of an elastic material and supported by a stem having a retainer. The valve body is housed, and the valve body is brought into contact with the valve seat of the valve body by the biasing force of a return spring disposed between the cap and the retainer, so that the valve body flows out from the inlet port of the valve body. In the check valve, the valve body is configured to open only by the pressure of the fluid, wherein a seat portion protruding along the axial direction of the stem is integrally formed on both side surfaces located at the outer peripheral edge of the valve body. 1. A check valve, characterized in that the check valve is configured such that when the valve body is assembled to a stem, either one of the seat portions comes into contact with a valve seat of the valve body.
