An rear end surface of a slide guide plate 12 extending rearward beyond a valve disc 6 is configured to abut against a rear step surface when the valve disc 6 is moving in a valve-opening direction, thus regulating a movement amount of the valve disc 6. This prevents the spring 7 from entering such

An rear end surface of a slide guide plate 12 extending rearward beyond a valve disc 6 is configured to abut against a rear step surface when the valve disc 6 is moving in a valve-opening direction, thus regulating a movement amount of the valve disc 6. This prevents the spring 7 from entering such an excessive compressive state that in a valve-opened state it is fully compressed. As a result, even in a case where the spring 7 is made of a synthetic resin, deterioration, due to stress relaxation, in a springing force can be suppressed, to suppress deterioration in a pressing pressure onto the valve disc 6 in the valve-closing direction, thus maintaining stable check valve functions.
