  • Patent number: 7669370
    Abstract: A weather strip includes an attaching base portion, and a hollow seal portion. The attaching base portion has a generally L-shaped cross-section, and includes a bottom wall and an exterior side wall. An elongation/shrinkage prevention portion is formed such that when the attaching base portion is curved in a direction of a width of the exterior side wall, a neutral axis of curvature is disposed at a position slightly offset toward a widthwise distal end of the exterior side wall from that portion of the exterior side wall continuous with the bottom wall. A double adhesive tape is bonded at least to that portion of an interior surface of the exterior side wall extending toward the distal end of the exterior side wall from a region at which a first hollow connecting portion of the hollow seal portion and the exterior side wall are interconnected.
