The two support parts are fixed to right and left sidewalls 41 of the bathtub 4. Four corners of the seat part are suspended by two suspension materials, four in total, extending downward from the two support parts. One end of each of the suspension materials is fixed to the support part. The other end is fixed to a drum whose rotary shaft is installed in the seat part.
