PURPOSE:To provide a bathtub having a high impact absorbing force forming the side wall part of a support leg having substantially a trapezoidal vertical section and formed of a top plate part and the side wall part into a forked form spread from the upper part to the end. CONSTITUTION:A tall support leg 2 is fixed to the corner part on the seat back side of a projection streak 12, and a low support leg 3 to the corner part on the drain hole side. The support leg 2, which has substantially a trapezoidal vertical section, has a side wall part 22 suspended from the periphery of a top plate part 21, and the side wall part 22 is formed into a forked form spread to the end by an outer wall 23 and an inner wall 24 inclined inward substantially symmetrically thereto. The top plate part 21 has a recessed groove 25 to which projection streaks 12, 13 are fitted and four circular through-holes 26 bored at equal intervals. A support leg 3, which has substantially a trapezoidal vertical section, has a side wall part 32 suspended from the periphery of the top plate part 31, and the side wall part 32 is formed into a forked form spread from the upper part to the end by an outer wall 33 and an inner wall 34 inclined inward substantially symmetrically thereto. The top plate part 31 has a recessed groove 35 to which projections 12, 14 are fitted and four circular through-holes 36 bored at equal intervals. |
