PROBLEM TO BE SOLVED: To enable waste water flowing into an inlet body to be smoothly discharged by setting a waste water fall starting point on the outside with respect to an opening edge on the side of a side wall portion. SOLUTION: This combined inlet 10, which comprises the inlet body 14 with a plurality of inflow ports 12, is arranged under a floor (100) of a detached house, so as to connect a plurality of drainage branch pipes (102) for discharging the waste water discharged from household equipment with a drainage main (106) for discharging the waste water to the outside. The inflow portion 12 comprises a short cylinder portion 38 which is protruded outward from a wall portion 22 of the inlet body 14, and a pipe connecting portion 40 which is formed at the one end of the short cylinder portion 38. The short cylinder portion 38 has a pipe bottom 42 which is inclined downward toward the side wall portion 22 from the pipe connecting portion 40, and a lowermost portion of the opening edge 44 on the side of the side wall portion 22 is in a position lower than that an opening edge 46 on the side of the pipe connecting portion 40. Thus, the waste water flowing into the inlet body 14 from the drainage branch pipe (102) starts to fall on the outside with respect to the opening edge 44 on the side of the side wall portion 22. Consequently, even if the forcible waste water flows into the inlet body, it properly changes its flowing direction to a downward one, so as to be smoothly discharged from an outflow portion 30.
