PROBLEM TO BE SOLVED: To provide a circulation adapter with bubble generating function capable of making a superior changing-over operability for a prescribed hot water flow passage.SOLUTION: A hot water flow passage changing-over mechanism B for performing a hot water flow passage changing-over operation for selectively flowing hot water supplied from an external source to one of an additional boiling hot water flowing-out passage 71 and a bubble hot water flowing-out passage 72 comprises an operating member 3, a valve shaft 63 displaced in a forward or rearward direction as the operating member 3 is moved and valve bodies 61, 62. The operating member 3 is provided with a guide surface 34 against which a bearing part 64 arranged at the valve shaft 63 abuts with a spring force, the guide surface 34 is applied as a recess part 35 where the region of a first end part 34a faces toward the rear side of an adapter main body part 5 and recesses, and a region between an edge part 35a of the recess part 35 and a second end part 34b is formed with an inclination surface 37.SELECTED DRAWING: Figure 5 |
