To provide a pipe connection structure configuring an earth path improving insertion hardness of a pipe while keeping electric connectivity.SOLUTION: A pipe connecting portion 23 is equipped with a hollow base portion 24, and a hollow pipe connection body portion 25 into which a pipe tip end portion 51 of a breather pipe 50 communicating to a tip end side of the base portion 24 can be inserted. On the base portion 24, an earth connecting portion 31 is formed, which has a cross-section projecting out from an outer peripheral surface 29 of the base portion 24 outward and to the pipe connection body portion 25 side in a generally L-shape and is formed with a pressing portion 32 pressing a conductive layer 52 of the breather pipe 50 from the outside of the breather pipe 50. On an outer peripheral surface 29 of the pipe connection body portion 25, a projection strip 28 is formed which presses the breather pipe 50 from the inside, on except for a proximal portion 29a with the pressing portion 32 and near the proximal portion 29a. A distance between the pressing portion 32 and the proximal portion 29a of the pipe connection body portion 25 is greater than a wall thickness of the breather pipe 50.SELECTED DRAWING: Figure 5

    【課題】電気的接続性を維持しつつ、パイプの差し込み難さを改善したアース経路を構成するパイプ接続構造を提供する。【解決手段】パイプ接続部23は、中空状の基部24と、基部24の先端側に連通するブリーザパイプ50のパイプ先端部51を挿入可能な中空状のパイプ接続本体部25を備え、基部24には、基部24の外周面29から外側、且つパイプ接続本体部25側に断面が略L字形に突出し、ブリーザパイプ50の導電層52をブリーザパイプ50の外側から押圧する押圧部32が形成されたアース接続部31が形成され、パイプ接続本体部25の外周面29には、押圧部32との最近接部29a以外であり、且つ最近接部29aの近傍に、ブリーザパイプ50を内側から押圧する突条28が形成され、押圧部32とパイプ接続本体部25の最近接部29aとの間の距離はブリーザパイプ50の肉厚より大である。【選択図】図5
