In a normally closed check valve, the valve is disposed in a pressure chamber and is pressed against the valve seat with a predetermined pressure force by the elasticity of a coil spring. A check valve characterized in that it is provided with at least a pair of concave and convex guide portions that maintain a reversible state of both members at times.
