PROBLEM TO BE SOLVED: To properly prevent generation of a clearance of a connection part in adjusting an orientation angle by forcibly displacing a drain pipe as in the past and a problem of a water leak and inferior connection due to this clearance, by properly and easily adjusting the orientation angle in a piping execution work state of the drain pipe. SOLUTION: In this pipe joint 1 provided with a plurality of branch pipe joints 1b to integrally protrude mutually at a fixed orientation angle from a side wall of an inspection cylinder 1a, a slide pipe joint 2 is formed as a nest in the branch pipe joint 1b, the slide pipe joint 2 and the branch pipe joint 1 are curved in circular arc shape by almost equal curvature in the nest part 3, by sliding the slide pipe joint 2 on a circular arc-shaped locus 4, an orientation angleαin a tip end part of the slide pipe joint 2 is adjusted, and a long- scaled pipe 6 for piping is connected to the tip end part.
