DRAINPIPE CONNECTING STRUCTURE OF PREFABRICATED BATH

PROBLEM TO BE SOLVED: To provide a connecting structure of a drainpipe of a bathtub which connects a connection pipe at a bathtub side and a connection pipe at a drain trap side at the end of the adjacent side between the bathtub and a washing place, and can prevent a water leak caused by the loosening of the screwing of a bathtub drainage elbow during connection. SOLUTION: The connecting structure of the drainpipe of the bathtub is provided with the connection pipe at the bathtub side, the connection pipe at the drain trap side, and a rotation restraint mechanism. One end of the connection pipe at the bathtub side is connected to the drainage elbow which is inserted to and connected to the drain outlet of the bathtub, and the other end is formed and extended toward the end side at one side of the adjacent side. One end of the connection pipe at the drain trap side is connected to the drain trap which is provided in the drain outlet part of the floor of the washing place, and the other end is connected to the other end of the connection pipe at the bathtub side in the field. The rotation restraint mechanism is used for preventing the connection pipe at the bathtub side from rotating with the drainage elbow as an axial center. COPYRIGHT: (C)2010,JPO&INPIT
