Abstract

PURPOSE: To improve construction work by previously fitting a socket in the downward protruded state to a drain hole opened on the bottom side of a toilet bowl, and then inserting the socket into a waste pipe embedded in the floor face to install the toilet bowl on the floor face. CONSTITUTION: At the time of connecting a waste hole H, opened on the bottom side of a toilet bowl 1, in conformity to a waste pipe 2 embedded in the specified position of the floor face F of a toilet, a socket 4 is previously fitted to the lower face of the waste hole H of the toilet bowl 1, with a gasket 3 interposed. The socket 4 is formed of a cylindrical part 4a protruded downward, a shoulder piece part 4b extended horizontally outward from the upper end of the cylindrical part 4a, and a step part 4c formed at the upper part of the shoulder piece part 4b. Packing 5 is previously fitted to the periphery of the cylindrical part 4a. When the cylindrical part 4a of the socket 4 is inserted into the waste pipe 2 from above together with the toilet bowl 1 to connect the waste hole H to the waste pipe 2, a tongue piece part 5a of the packing 5 is elastically fitted to the inner peripheral surface of the waste pipe 2 so as to be able to secure positive sealing performance.
