<P>PROBLEM TO BE SOLVED: To arrange a flow passage switching unit in a narrow dead space between a bathroom wall surface and a bathtub wall surface so that it can move to follow up the retracting movement of the bathtub. <P>SOLUTION: Between outward pipes 30a, 30b of a reheating circulation passage, a flow passage switching unit 36 which changes over from a flow passage of a heating circulation system to a flow passage of a drain system from the outward pipe 30b to a drain passage 48 or vice versa is mounted to be slidable on a unit fixture 75 and screwed to be fixed to the unit fixture 75. A raised plate 77a of the unit fixture 75 is fixed to a bathroom wall surface facing a short-side side face 32a of the bathtub 32. Because the flow passage switching unit 36 is slidable in a direction A so as to increase a retracting movement amount of the bathtub 32 as the bathtub 32 is unscrewed and retracted in the direction A, an object dropped into the dead space can be easily taken out. <P>COPYRIGHT: (C)2012,JPO&INPIT |
