PURPOSE: To prevent a drainage from interfering chain with the body of a bathing person. ;CONSTITUTION: In a drainage-port center type bathtub, in which a drainage port 2 is formed to a section near a central section in the longitudinal direction of a tank section 3 and in the vicinity of a tank wall 4, a recessed section 11 is formed to the tank wall 4 or an arm rest section 5, and a drainage chain 8 is received in the recessed section 11. Since the drainage chain 8 is received in the recessed section 11, the drainage chain 8 is difficult to touch with the body of a bathing person, thus allowing comfortable bathing.;COPYRIGHT: (C)1993,JPO&Japio
