PURPOSE:To make improvements in operatability, by installing plural guide grooves paralleling the peripheral surface of a grooved cam as well as installing a working groove discharging the whole quantity of hot and cold water in connection to the guide groove and a stop position stopping water when a working groove for flow regulating use and a guide valve are engaged with each other. CONSTITUTION:Plural guide grooves 12 and 12' being paralleled in spiral form are installed on the peripheral surface of a single grooved cam 5, and a working groove 13 discharging the whole quantity of hot and cold water in contact with the inner end of each of these guide grooves 12 and 12' is made up in semicircular form. And, a working groove 14 regulating a flow rate with its section crest type center concave tilted by a deep notch is installed at the central part of the working groove 13, while each of stop positions E and E' stopping water when paired valve guides are engaged with each other is installed in the deepest part of the working groove 14. With this constitution, a hot water valve and cold water valve are operated at the same time with the single grooved cam 5, and simultaneous flow adjustment and separate stoppage of hot and cold water are made possible to be done so that combined operation comes so easy.
