The invention provides a joint superior in such characteristics as oil resisting property, heat resisting property, ozone resisting property, sealability, and connectibility, and requiring less cost. A joint (30) disposed in an intake path between the cylinder and carburetor of an engine and applied to the connecting portion of an intake pipe that becomes a flow path for mixed gas fed from the carburetor, the joint comprising a joint main body (31a, 31b) made of nitrile rubber with chlorine resin added thereto, a fastening portion (32a, 32b) formed on the cylinder side of one axial end of the joint main body (31a, 31b) for fastening the joint main body (31a, 31b) to the cylinder, and a seal portion (33a, 33b) made of nitrile rubber and formed on the fastening surface between the fastening portion (32a, 32b) and the cylinder for sealing the fastening surface.

L'invention concerne un joint amélioré en ce qu'il possède des caractéristiques de résistance à l'action de l'huile, de la chaleur et de l'ozone, d'étanchéité, de capacité de branchement et de moindre coût. Ledit joint (30) est disposé dans une tubulure d'admission située entre le cylindre et le carburateur d'un moteur, et est appliqué sur une partie de branchement d'une pipe d'admission qui devient un chemin d'écoulement de mélange gazeux provenant du carburateur. Le joint comprend un corps principal (31a, 31b) en caoutchouc nitrilique auquel on a ajouté une résine de chlore, une partie de fixation (32a, 32b) formée sur le côté cylindrique d'une extrémité axiale du corps principal (31a, 31b) afin de fixer ledit corps principal (31a, 31b) audit cylindre, et une partie de joint (33a, 33b) en caoutchouc nitrilique formée sur la surface de fixation entre la partie de fixation (32a, 32b) et le cylindre afin de fermer la surface de fixation de manière étanche.
