<p>PURPOSE:To prevent vibration from its mutual transmission by elastically connecting together both members while ensuring air-tightness in a connecting part between the tubular members by which a gas flow path is formed. CONSTITUTION:A constitution is provided so as to form a flexible structure such that two tubular members 1, 4 connected for forming a gas flow path 10 and a rubber gasket 3 interposed between the tubular members 1, 4 are provided to form an annular groove 6 in a surface closely attached to the rubber gasket 3 of the tubular members 1, 4 and to form an annular lip 8 fitted into the annular groove 6 in the rubber gasket 3, and a point end part of the annular lip 8, while flexing in a circumferential internal or external direction in accordance with an internal pressure fluctuation in the gas flow path 10, can be closely attached to an internal or external peripheral side wall surface of the annular groove 6.</p> |
