  • Patent number: 10272757
    Abstract: An outer lip is continuous with an outer-cabin side wall which has a linear shape of a hollow seal member. The outer lip makes elastic contact with a surface of a body in a direction substantially perpendicular when a door is closed. A rear lip extends from a position close to a base root of the outer lip toward an outer-cabin side and makes elastic contact with a peripheral edge of the door. A thickness of the outer-cabin side wall of the hollow seal member is not less than a thickness of a vertical part of the outer lip; and an inner-cabin side surface of the outer-cabin side wall of the hollow seal member is closer to an inside of the automobile than an inner-cabin side surface of the vertical part of the outer lip.
