PROBLEM TO BE SOLVED: To provide a pipe connection structure capable of reducing man-hours for connection work, and accurately connecting cylindrical pipes.SOLUTION: One embodiment of this disclosure is a connection structure for two pipes used in a vehicle. One pipe has, at its tip, a cylindrical insertion part inserted into the other pipe. The other pipe has, at its tip, a cylindrical reception part into which the insertion part is inserted, which is perpendicular to at least a center axis of a hollow part, and whose cross section is formed into a circular shape. In a region where the reception part and the insertion part are overlapped, provided is at least a screw hole penetrating the reception part and the insertion part in a radial direction. Into at least a screw hole, a bolt is screwed.SELECTED DRAWING: Figure 2
【課題】接合作業の工数を低減しつつ、かつ精度よく円筒状のパイプ同士を接合できるパイプの接合構造を提供する。【解決手段】本開示の一態様は、車両に用いられる2つのパイプの接合構造である。一方のパイプは、他方のパイプの内部に挿入される円筒状の挿入部を先端に有する。他方のパイプは、挿入部が挿入されると共に、少なくとも中空部の中心軸と垂直な断面形状が円である筒状の受容部を先端に有する。受容部及び挿入部の重なる領域には、受容部及び挿入部を半径方向に貫通する少なくとも1つのネジ穴が設けられる。少なくとも1つのネジ穴には、ボルトが螺合される。【選択図】図2
