PROBLEM TO BE SOLVED: To provide a piping member hardly producing problems such that, even when a horizontal branch pipe from a toilet bowl or the like is connected, clogging of another facing horizontal branch pipe occurs, and capable of being shortened in widthwise size in front view and compactly housed in a pipe shaft.SOLUTION: A piping member 10 for collecting drain water comprises: a pipe body part 120 in which a pair of drain water introduction ports 160 opened to an inner wall surface are formed facing each other; and a pair of joint pipe parts 140 projecting from the pair of drain water introduction ports 160 respectively. Horizontal branch pipe connection parts 240 to which a pair of horizontal branch pipes 180 are connected in parallel to each other are formed at the tips of the pair of joint pipe parts 140, respectively. An opposing direction L1 of the drain water introduction ports 160 is set non-parallel to a connection direction L2 of the horizontal branch pipes 180. |
