PROBLEM TO BE SOLVED: To prevent danger such as trap of the leg of a baby by a chain during bathing and to improve safety by integrally providing an arm piece projecting outward on a plug body that is attached or detached for a drain outlet provided in a bottom plate of a bathtub, and rotatably fixing the tip of the arm piece near the drain outlet in the bottom plate. SOLUTION: A plug body 4 integrally projects an arm piece 5 outward, and a mounting hole 6 is drilled in the tip of the arm piece 5. This arm piece 5 has flexibility to be easily bent. A hole portion 7 is provided near a drain outlet 3 in a bottom plate 2 of a bathtub 1. The arm piece 5 of the plug body 4 is rotatably fixed to the bottom plate 2 of the bathtub 1 through a plastic- made fastener 9. The fastener 9 fixes the arm piece 5 of the plug body 4 by penetrating a cylindrical leg portion 11 through a mounting hole 6 provided in the arm piece 5 of the plug body 4, and pressing and engaging the cylindrical leg portion 11 into the hole portion 7 provided in the bottom plate 2 of the bathtub 1. Thus, the arm piece 5 integrally projecting from the plug body 4 plays as a conventional chain role.
