An outer weatherstrip formed of a thermoplastic elastomer fitted to an upper edge portion of a door panel of an automobile door, for sealing a space between the door panel and a door glass includes a main body consisting of a vehicle interior-side side wall, a top wall, and a vehicle exterior-side side wall, and an upper seal lip and a lower seal lip protruding from the vehicle interior-side side wall to the door glass side. A plasticizer-rich layer and a plasticizer-rich layer containing a higher proportion of a plasticizer component compared to the thermoplastic elastomer forming the upper seal lip and the lower seal lip are formed on the sides of the upper seal lip and the lower seal lip abutting on the door glass.

Outer weatherstrip

A glass run includes a main body corresponding to an extrusion molding part and a glass run corner part, formed with a vehicle outside groove part between a vehicle outside sidewall and a vehicle outside cover lip, the main body being formed with a vehicle inside groove part between a vehicle inside sidewall and a vehicle inside cover lip, and tips of a door frame being inserted into the vehicle outside groove part and the vehicle inside groove part. In the glass run corner part, an engagement bead part is formed in at least one side surface, which faces the vehicle outside groove part, of the vehicle outside sidewall and the vehicle outside cover lip, a long caulking sponge member is inserted into the vehicle outside groove part, and the engagement bead part compresses an end part of the caulking sponge member to be engaged with the end part.

Glass run

An automotive glass run that is attached to an inner periphery of a door frame of an automotive door, guides ascending and descending of a door glass, and is formed of a thermoplastic elastomer, includes: a main body having a substantially U-shaped cross section, the main body including a vehicle-exterior side wall, a vehicle-interior side wall, and a bottom wall; a holding lip that extends from at least one of the vehicle-exterior side wall and the vehicle-interior side wall and abuts on the door frame; and a plasticizer rich layer formed on at least one side of the holding lip abutting on the door frame, the plasticizer rich layer including a large amount of plasticizer component compared to the thermoplastic elastomer forming the holding lip.

Automotive glass run

A vehicle body structure is provided that prevents a glass window in a fully closed state from moving toward inside a vehicle. The vehicle body structure for use with a door includes: a vehicle body; and a run channel that is interposed for sealing between the vehicle body and a glass window that is slidably arranged in the door, wherein the run channel includes a base portion that is mounted to the vehicle body, and a hollow frame portion that elastically contacts the glass window and defines a hollow portion with the base portion, and the hollow frame portion is deformed when the glass window is fully closed so that the hollow portion is shrunk by the glass window, to cause at least a part of the hollow frame portion to closely contact the base portion.

Vehicle body structure

According to an attaching structure of a roof side weather strip, a retainer includes a vehicle upper side wall, a connecting part, and an inboard side wall. A first tip locking part, formed in a tip of the vehicle upper side wall, is engaged in a tip locking groove, formed in a tip of a vehicle upper side wall of the weather strip. The vehicle upper side wall of the weather strip is held by the vehicle upper side wall of the retainer. The inboard side wall of the retainer is allowed to abut on an inboard side wall of the weather strip, and a tip of a second tip locking part formed by bending the tip obliquely in the inboard direction is engaged in the engaging groove, so that the inboard side wall of the weather strip is held by the inboard side wall of the retainer.
