Abstract: In a single lever mixing valve, having a sliding member sliding on a lever holder, for adjusting an amount and temperature of discharge water by rotating a disk actuating stem on an axis thereof or by operating a handle lever for inclining the disk actuating stem. A fit-in hole is so formed on the handle lever that the disk actuating stem is loosely fitted therein, with a gap formed between a side surfaced of the disk actuating stem and a gap-defining inner surface of the handle lever; a spacer so sized as to close the gap is provided; a spacer insertion hole is formed in the handle lever such that the spacer insertion hole is open on an outer surface of the handle lever; and the spacer is inserted into the spacer insertion hole to fix the disk actuating stem fitted in the spacer insertion hole.

Abstract: The present invention is directed to a bellows tube formed of metal having a cylindrical collar portion and a plurality of corrugations adjacent thereto with outwardly curved portions and inwardly curved portions alternately formed along the longitudinal axis of the tube. The bellows tube includes a bulged end portion which extends from a first outwardly curved portion of the outwardly curved portions toward the collar portion. The bulged end portion is bulged outward of the tube, with its outer diameter gradually reduced from the first outwardly curved portion to the collar portion. A connecting end portion is formed for connecting the bulged end portion with the collar portion, and the connecting end portion is curved inward of the tube. Preferably, the radius of curvature of the connecting end portion is smaller than the radius of curvature of the first outwardly curved end portion.
