Abstract: PURPOSE: To enable even the bath tub side wall of an already set unit bath room to be protected, by mounting one end of a side wall engaging body on the tip end of a lateral column and engaging the other end of the side wall engaging body with the bath tub side wall. CONSTITUTION: The lower end of a longitudinal column 9 pushes the lower end of a washing place side wall 6, a lateral column 10 pushes the upper part of a bath tub side wall 4 positioned almost on the diagonal line to the lower end of the longitudinal column 9. Consequently, when a load is applied on the lateral column 10, the tip end part 27 of the lateral column 10 descends by an amount of bending generated when the load is applied on a cantilever beam, but not less than that. When the left end of a swing bar 26 descends, the right end only slightly rotates, caused by a shaft 32 and a pressing board 33 hardly descendible by the friction with the bath tub side wall 4. Consequently, the gap 28 between the lateral column 10 and the swing bar 26 is decreased by the descending lateral column 10. The pressing board 33 never damages the side wall 4 rubbing over the bath tub side wall 4 as far as the gap becomes not zero. That is, the gap 28, the shaft 32, etc., are to be rubbing prevention devices of the bath tub side wall 4.
