PROBLEM TO BE SOLVED: To improve the workability of an attaching work for a bathtub body by providing a construction setting a drain mechanism body and an operation mechanism body to a constant position by absorbing an error in the thickness of a bathtub body and further attaching a drain plug mechanism in advance. SOLUTION: A drain plug mechanism 5 is built in an attaching pipe 4. Inside an operation joint and an drain joint 42, supporting bodies 6, 6 supporting an operation mechanism body 51 and a drain mechanism body 52 are built in a manner permitting the reciprocating motion in the axial direction. Throughout the supporting bodies 6, 6, operation cylinder body 2 and a drain cylindrical body 3, fixing means 7, 7 for fixing both of them in one united body are provided. By this construction, the installation to the bathtub body A is made possible with the drain plug mechanism 5 held in a built-in state.
