Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a pipeline connection structure which inhibits the deterioration caused by hydrolysis and improves the durability.SOLUTION: In a resin cylindrical member 20, stopper parts 24 are formed protruding from an outer peripheral surface of the cylindrical member 20 to the radial outer side. Each stopper part 24 has a stopper surface 24A with which an apical surface of a pipe body 18 is butted. A groove 26 forming a non-contact space 28, which prevents a radial inner end part of the apical surface of the pipe body 18 from contacting with the stopper part 24 and communicates with outer air, is formed between the outer peripheral surface and the stopper surface 24A. 【課題】加水分解による劣化を抑制して、耐久性を向上させた配管接続構造を得る。【解決手段】樹脂製の筒部材２０には、筒部材２０の外周面から径方向外側にストッパ部２４が形成されている。ストッパ部２４は、管体１８の先端面が突き当てられるストッパ面２４Ａを有している。外周面とストッパ面４４Ａの間には、管体１８の先端面の径方向内端部とを非当接にすると共に外気に連通する非当接空間２８を構成する溝２６が形成されている。【選択図】図２
