Claims

[Scope of utility model registration request]

A lid body disposed inside the bathtub so as to cover a through hole formed in the bathtub side wall; a tightening plate disposed outside the bathtub and sandwiching the bathtub side wall together with the lid body via a packing; It has screw means for tightening the center portions of the lid body and the tightening plate in a direction in which they approach each other, and a portion of the tightening plate inside the peripheral wall of the through-hole projects wholly or partially toward the side of the through-hole. The closure of a through hole in a bathtub is characterized in that the clamping plate and the lid are positioned at a position where their centers coincide with the center of the through hole based on the engagement between the protrusion and the peripheral wall of the through hole.
