The pipe includes a stay in which a stay-side abutting portion and a stay claw portion intersect with each other in an L shape.

In a case where a length of the stay claw portion in the insertion direction is set to Ls, a distance from the case wall surface to the case-side abutting portion is set to Lg, and a distance from the case wall surface to the second protrusion portion is set to Lp, Lg-Lp<Ls.ltoreq.Lg is satisfied.
