  • Patent number: 10654349
    Abstract: A sealing structure for an automobile door includes a roll sash with a projection on an inner-cabin side surface of an upper end periphery thereof, a press sash without a projection and joined to the roll sash, and a decorative molding which covers the sashes. An installation base member of a weather strip is configured to operably couple to an outer circumferential edge on an upper side of the door sash. The weather strip includes a hollow seal member and an outer seal lip. An outer-cabin side end of the installation base member and a rib-shaped protrusion which extends outwardly toward an exterior of an automobile are configured to clasp the projection. An upper part protrusion which extends outwardly toward the exterior of the automobile from an upper side relative to the rib-shaped protrusion is configured to make close contact with an upper part of the decorative molding.

  • Patent number: 10507714
    Abstract: The present disclosure can reduce a force required for the attachment of a sealing member to a flange of a body of an automobile, thereby facilitating the attachment, and can reduce the separation of the attached sealing member from the flange to ensure good seal. An outer foam 25 which comes into contact with an exterior face of a flange 110 facing the outside of a cabin is provided for an inner face of an outer wall 20. A flexible seal lip 21a is provided for an inner face of an inner wall 21. A bottom foam 26 bulges from an inner face of a bottom wall 22. A distance between the outer and bottom foams 25 and 26 in a width direction of the automobile is smaller than a thickness of a thinnest portion of the flange 110.
