ABSTRACT:
A quick connector includes: a connector body having a retainer holding portion, a tube connecting portion to be press fitted into a tube, and a housing between the retainer holding portion and the tube connecting portion, the tube connecting portion being formed with a plurality of annular projections being axially spaced apart from each other; and a retainer which is held in an axially fixed state by the retainer holding portion. A portion of an outer surface of the tube connecting portion extending from the annular projection, which is closest to the housing, toward the housing is formed into a tapered surface whose diameter is gradually enlarged toward the housing, and a diameter of an annular projection side of the tapered surface is set to be larger than a diameter of the outer surface of the tube connecting portion between the annular projections.
