PROBLEM TO BE SOLVED: To provide a stable sitting board for a bathtub, which is formed by simplifying the construction of a sitting chair installed in the bathtub through simplification of fitting and installation of the sitting board to the bathtub, and adjustable in the installation height convenient to sitting, and preventing the sitting board installed in the bathtub from being moved unexpectedly. SOLUTION: Forked rotors 7 formed by a placing piece 5 extended from a rotating shaft part 3 on one side and a pressing piece extended on the other side are rotatably fixed to both end parts of the sitting board 3 bridged and placed on stepped parts 2 formed opposite to each other on the inner wall surface of the bathtub 1, whereby when the sitting board 3 is set on the stepped parts 2, the placing pieces 5 of the forked rotors 4 are placed on the stepped parts 2 of the bathtub 1 to turn the forked rotors 4, and the pressing pieces 6 are pressed to the lower clamping wall surfaces below the stepped parts 2. |
