ABSTRACT:
An allowable angle of a float valve member with respect to a valve case is so set that a deformed direction, as caused by a gate position at a injection molding time, of a inner circumference of a communication hole of the valve case with respect to a roundness and a deformed direction, as caused by a gate position at a injection molding time, of an outer circumference of a crest portion of the float valve member with respect to the roundness may be substantially aligned. Between the valve case and the float valve member, there is an interposed angle regulating unit for preventing the angle of the float valve member with respect to the valve case from varying over the allowable angle.
