Then, the through hole (12) is opened, the mixing chamber (1) and the mixed water flow path (11) are communicated, and the mixed water is sent to the water discharge pipe (13). Further, the opening amount of the on-off valve (15) is adjusted by pressing down the operation handle (6), and at the same time the opening and closing of the through hole (12) is adjusted to adjust the outflow amount of the mixed water.
