CONSTITUTION:A U-like shape metal frame 8 having an opening part 10 for fitting a packing on the bath room 9side is secured to the top end part of a side wall 2. Further, an upright wall 8a of the frame 8 is made into contact with a bent piece 1a of a ceiling wall 1, and the horizontal outer periphery of the ceiling 1 is supported to a horizontal wall 8b of the frame 8. Further, the upright wall 8a is fixed to the bent piece 1a by fixing screws 4, and the packing 5 is press-fitted in the opening 10 in the frame 8. With this arrangement, it is possible to facilitate the fitting of the packing 5. |
