PROBLEM TO BE SOLVED: To prevent air-leak from a structure to a degree that practical use is not hindered by forming as a substantially Y-shaped structure which extends linearly along the longitudinal direction and which has a substantially Y-shaped outline form when viewed from a cross-sectional plane orthogonal to the longitudinal direction. SOLUTION: The air-leak preventing member 10 is formed to extend linearly along a longitudinal direction and have a substantially Y-shaped outline form on a side in contact with a contact portion TS when viewed from a cross-sectional plane orthogonal to the longitudinal direction. Then seams between respective side walls 28C, 28A are sewn from over a synthetic sheet 34 to interpose a trunk 12 between borders of adjacent components at the contact portion TS. This constitution allows an external surface of the member 10 to come into substantially tight contact with surfaces of the side walls 28A, 28C to close a gap airtightly to some degree. Thus gas passing through the seams can be prevented from flowing in/out to a degree that there is no hindrance in practical use.
