This heat insulating structure for an exhaust junction pipe disposed at a section at which exhaust pathways of different lengths merge, and the heat insulating structure has a first heat insulating section that performs heat insulating by covering at least a portion of a branch that configures a short exhaust pathway and that configures the exhaust pathway before the junction among the branches of the branched exhaust junction pipe. L'invention porte sur une structure d'isolation thermique pour un tuyau de jonction d'échappement disposé en une section au niveau de laquelle se rejoignent des trajets d'échappement de différentes longueurs, laquelle structure d'isolation thermique a une première section d'isolation thermique qui effectue une isolation thermique par le fait de recouvrir au moins une partie d'une ramification qui constitue un trajet d'échappement court et qui constitue un trajet d'échappement avant la jonction entre les ramifications du tuyau de jonction d'échappement ramifié. 　長さが異なる排気経路を合流させる部分に配置される排気合流管の保温構造であって、この保温構造は、枝分かれした排気合流管の各枝部のうち、合流前の排気経路を構成する枝部であって、短い排気経路を構成する枝部の少なくとも一部を覆って保温する第１保温部を有するものである。
