To autonomously control adaptation of the jet temperature actually jetted from a jetting port and a selected operation mode by a circulation adapter single body, in a circulation adapter switching a reheating operation mode and a bubble operation mode.
A shape memory alloy spring 73 is put in a contracted state at a low temperature, and a first switching valve 56 closes a first recessed part 60, and opens a cutoff part 65, and hot and cold water is supplied to a swirling chamber 42 via a swirling preliminary chamber 45 and a communicating passage 44, and is jetted from a fine jet jetting port 24. When high temperature hot and cold water is supplied in the circulation adapter 4, the shape memory alloy spring 73 is set so as to expand by sensing a temperature change, and a bias spring 70 is compressed, and the first switching valve 56 opens a valve, and closes the cutoff part 65, and the hot and cold water turns to a reheating jet jetting port 26 via first and second recessed parts 60 and 61 of a supply chamber 46.
