By adjusting the matching openings of the hot water valve hole 23 and the water valve hole 24 of the fixed valve body 16, the supply amounts of hot water and water are changed, and the temperature of the mixed water is appropriately set, and
By vertically rotating the operating handle 22,
The relative opening ratios of the long hole 31 of the movable disk 18 and the hot water valve hole 23 and the water valve hole 24 of the fixed valve body 16 are kept constant, and the respective matching opening amounts are adjusted. By doing so, the flow rates of hot water and water are appropriately changed.
Needless to say, the above-described operation of each handle can be performed smoothly at all times by sliding contact between the movable disk 18 made of a ceramic material and the fixed valve body 16 made of a resin material, and the occurrence of ringing or the like is eliminated. Absent.
