PROBLEM TO BE SOLVED: To provide a seal structure using a gasket capable of precisely maintaining sealing performance of a fastening part even if external force is applied to a tube body fastened to a housing. SOLUTION: A check valve T having a tapered surface in a tip part 35 thereof and provided with a screw part 39 in rear thereof and provided with a flange part 33 enlarged in diameter from the screw part 39 is fastened to a housing 32 of a high-pressure fuel pump, which is provided with a through hole 38 in a side wall thereof and a circular hole 39a and a screw hole 31 enlarged in diameter from the through hole 38, by screwing the screw part 39 to the screw hole 31. A gasket G is interposed between the housing 32 and the check valve T to seal a fastening part of the housing 32 and the check valve T to each other. The gasket G formed into a ring shape is interposed between the tapered surface of the tip part 35 of the check valve T and the enlarged-diameter circular hole 39a provided in the side wall of the housing 32.
