<p><P>PROBLEM TO BE SOLVED: To allow troublesomeness of controlling a tightening force to be removed when connecting a collar part of a drain outlet peripheral part and a pipeline by a drain outlet member, and to drastically improve the working efficiency. <P>SOLUTION: A plurality of guide parts 24 are formed projecting on an upper inner peripheral surface of a body part 21 of a connection joint 20, and a plurality of locking projections 34 are integrally formed at predetermined intervals in an outer peripheral direction on the outer peripheral surface on a lower end side of a cylindrical part of a drain outlet member so as to project in an outer peripheral direction. When mounting the drain outlet member, the drain outlet member is fitted downward to be in a first state so that each of the locking projections 34 is positioned between the guide parts 24, and the drain outlet member is rotated by a predetermined amount from the first state. By this rotation, the locking projections 34 are rotated along the lower edge of the guide parts 24 and guided downward. In a second state where further rotation is restricted, a collar part 15 of a bathtub 10 is held between a support part 22 of the connection joint 20 and an overhang part 32 of drain outlet member. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
