[Effect of the action and INVENTION fine communication of claim 1, as described above
Concrete is a short tube connection flange and straight pipe used for connecting the drainage mains and sanitary fitting drain port which was constituted by integrally molded body, and their drainage mains According to this connection structure It is possible to reduce the number of parts required for connection with the drain port and to reduce the number of assembling steps.

In the connecting structure of the first aspect, the plate-shaped fixing piece is projected outwardly in the direction perpendicular to the axis from the outer peripheral portion of the connection flange, and either the front face or the rear face of the fixing piece is fixed to the piping case. It can be fixed in a state in which it is applied to the rear surface or the front surface of the attached mounting bracket.

Conventionally, two types of front plates, a thick plate and a thin plate, are mainly used as front plates disposed on the front surface of a piping case. In this case, the front end position of a connection flange is fixed. Therefore, the amount of protrusion of the front end of the connection flange from the front of the front plate differs between the case where a thick plate is used and the case where a thin plate is used as the front plate. When it is attached to a sanitary ware, it becomes difficult to seal the sanitary ware drainage port and the connection flange well.

However, according to the present connection structure , whether the fixing piece of the connecting flange is fixed with the front surface thereof in contact with the rear surface of the mounting bracket, or the fixing piece is fixed with the rear surface of the fixing piece in contact with the front surface of the mounting bracket. By selecting either one, the position of the front end of the connection flange can be adjusted back and forth.

If the adjustable front and rear positions are determined in advance for the case where the thick front plate is used and the case where the thin front plate is used, any of the front plates can be used. In this case, the front end of the connection flange can be always positioned at an appropriate position, and the sanitary fitting drain port and the connection flange can be connected in a well-sealed state.

[0015] In the connection structure of the claim 1, it is to keep the fixing piece according to the front face of the fixing piece is positioned at a predetermined distance behind the front end of the connection flange arranged form
it can. With this configuration, the front end of the connection flange can be satisfactorily protruded forward by a predetermined distance from the front surface of the front plate, so that the connection with the sanitary appliance drain port can be easily performed.

According to a second aspect of the present invention, an ear piece projects outward in a direction perpendicular to the axis at a predetermined location on an outer peripheral portion of the connection flange, and a thick part and a thin part are formed on the ear piece, and mounting is performed. A notch is formed in the bracket so as to fit the thick part at a predetermined rotation angle position, so that either the thick part or the thin part of the ear piece is brought into contact with the mounting bracket.

Also in this connection structure of the present invention, it is possible to adjust the front end position of the connection flange back and forth by contacting either the thick portion or the thin portion of the ear piece with the mounting bracket. Therefore, even in this connection structure , it is possible to cope with the case where either a thick plate or a thin plate is used as the front plate.

[0018] In the present invention, can be made so as to also serve the fixing piece to the mounting bracket of the connection flange with a said lug. This eliminates the need to separately provide the ear piece and the fixing piece.

In the connecting structure of the second aspect, the front of the thick portion or the front of the thin portion of the ear piece may be brought into contact with the rear surface of the mounting bracket. Ru conveniently der that so as to abut the rear surface of the thin portion on the front of the mounting bracket. In particular, when the ear piece and the fixing piece are used in combination, and when the rear face of the ear piece is brought into contact with the front face of the mounting bracket, there is an advantage that the fixing operation can be performed from the front side of the piping case.
