Zusammenfassung:	PROBLEM TO BE SOLVED: To simplify the weight saving and assembling steps.SOLUTION: A seal structure 52 comprises: a branch pipe 12 (pipeline); a cylinder head 20 having an exhaust port 30 (insertion hole), into which one end 12a of the branch pipe 12 is inserted; and a gasket 50 fitted on the outer circumference of the branch pipe 12 while at least one portion being inserted into the exhaust port 30 and having an enlarged diameter part 50c abutting against the inner circumference 30a of the exhaust port 30, as it departs the other side of the branch pipe 12. As the pressure of the exhaust gas rises, the pressure of the exhaust gas to act upon the enlarged diameter part 50c is a load (black arrow) for the enlarged diameter part 50c to extend radially outward.SELECTED DRAWING: Figure 4 【課題】軽量化および組み付け工程を簡易化する。【解決手段】シール構造５２は、支管１２（配管）と、支管１２の一端１２ａが挿通される排気ポート３０（挿通孔）が設けられるシリンダヘッド２０と、少なくとも一部が排気ポート３０に挿通されるように支管１２の外周に装着され、支管１２の他端側から離隔するほど外周側に拡がり、排気ポート３０の内周面３０ａに当接する拡径部５０ｃを有するガスケット５０と、を備える。排気ガスの圧力が大きくなると、拡径部５０ｃに対して作用する排気ガスの圧力は、拡径部５０ｃが径方向外側に拡がる向き（黒矢印）の荷重となる。【選択図】図４
