The valve body is always energized in the direction of crimping the valve body, and is configured to move the valve element to the valve open position against the energizing force of the return spring by the pressure of the fluid supplied to the inlet port of the valve body. In the check valve, a cushion piece is provided on the other end surface of the valve body opposite to the seat portion and in contact with a stopper surface when the valve body moves in the valve opening direction. A check valve featuring:
