To provide a hot water supply port adapter for a bathtub, capable of preventing the corotation of an attaching member outside the tub during attachment to a bathtub side wall by the rotating operation of an attaching member inside the tub.
For the hot water supply port adapter for the bathtub, the cylindrical part 2a of the attaching member 2 inside the tub is screwed and connected through the through-hole H of the bathtub side wall Ta to the attaching member 1 outside the tub to be piped and connected to a water heater outside the bathtub T. On the contact surfaces 50a and 50b of ring-like packing 5 interposed between the outer surface of the bathtub side wall Ta and the annular end face of the attaching member 1 outside the tub, a plurality of ring-like ribs 51a-51e and 52a-52d and projected parts 55 and 56 positioned at a plurality of parts in the peripheral direction of annular grooves 53b, 53c, 54b and 54c between the ring-like ribs are provided. By tightening a thread-engagement part by the rotating operation of the attaching member 2 inside the tub, the ring-like packing 5 is compressed between the bathtub side wall Ta and the attaching member 1 outside the tub, and the projecting parts 55 and 56 closely adheres to the contact surfaces on the opposite side.
