A valve wholly made of a synthetic resin and being of the type wherein a body (1) and a flanged body cap (5) are coupled to each other by screwing a cap nut (6) to the peripheral surface of the body (1). The body cap (5) consists of a tubular first element (9) with a disengagement-preventing portion formed at the end to be connected to the body (1). An annular groove (9a) is formed inwardly of the disengagment-preventing portion. A ring-like element (10) having a small diameter portion (10a) adapted to be fitted into the annular groove (9a) of the first element (9) and a large-diameter portion (10b) adapted to contact the outer surface of the disengagement-preventing portion of the first element (9) is cut at one side in this circumferential direction to form two cut ends (101, 102). The first element (9) is coupled to the ring-like element (10) whereby the ring-like element forms the seat of the body cap. |
