The present invention relates to a reed valve (19) which uses the reed shaped valve body (23) to control the air inflowing. A fixed end (23A) of the reed shaped valve body (23) which is used to block the valve port (25) is installed on the valve main body (24) arranged with the valve port (25). The first bending part is composed by bending the free end (23B) of the valve body (23) to the direction of the valve main body (24) and the second bending part is formed by bending the free end of the valve to the inverse direction to the fixed end (23A). A tieing stop hole (27) is arranged at the valve installing surface (24S) of the installing valve body (23) of the valve main body (24). The bended free end (23B) of the valve body (23) is inserted into the tieing stop hole (27). The free end (23B) is tieing stopped at the position where the second bending part (232) contacts the step part (27A) of the tieing stop hole (27) if the valve body (23) is warped by the pressure. In this way the valve can prevent that the v
