A glass run having a general portion formed by extrusion molding and a mold-forming portion that connects terminals of the general portion attached to a corner portion of a door frame has a substantially U-shaped cross section including a vehicle exterior side wall, a vehicle interior side wall, and a bottom wall joining the vehicle exterior side wall and the vehicle interior side wall; and has a vehicle exterior side seal lip and a vehicle interior side seal lip that obliquely protrude in an inner direction of an opening having the substantially U-shaped cross section from the vehicle exterior side wall and the vehicle interior side wall, respectively, and the vehicle exterior side seal lip of the mold-forming portion is formed with a seal lip extension portion having a seal lip length extended as compared to the vehicle exterior side seal lip formed in the general portion.

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.

Methods of forming an article from a molten plastic composition comprising a polymer and a blowing agent. The methods include injecting the molten plastic composition into a mould, allowing the plastic composition to form a first solid skin adjacent to an in contact with a first cavity-forming surface of the mould and a second solid skin adjacent to and in contact with a second cavity-forming surface of the mould, and then opening the mould before the molten plastic composition between the first and second solid skins in at least one portion of the circumference of a region of the mould cavity defining an annular cross-section of the cavity has solidified.

A corner die-molding portion of a glass run includes an outer peripheral portion to cover an end flange portion of an outer panel of a door, a holding portion having one end portion connected to an inner surface of the outer peripheral portion, and a supporting portion provided between the holding portion and the inner surface of the outer peripheral portion. An inner space and its opening are provided between the outer peripheral portion and the holding portion such that, when the glass run is attached to a window frame, the end flange portion of the outer panel is inserted into the inner space from the opening, and then the supporting portion is brought into abutment against a tip end of the end flange portion of the outer panel. It is possible to suppress flexural deformation of the outer peripheral portion, thereby improving the glass run in external appearance.

Sealing performance is improved without deteriorating appearance. A pillar P side of a roof-side seal lip 34 and a roof R side of a pillar-side seal lip 43 are spaced apart from each other in a transverse direction of a vehicle when a door 110 is open. The pillar P side of the roof-side seal lip 34 is formed so as to be closer to the roof R side of the pillar-side seal lip 43 toward an end of the pillar P side. When the door 110 is closed, the roof-side seal lip 34 comes into contact with the pillar-side seal lip 43.

A cover for a door frame includes: a sealing member mounted to the door frame; and an inner cover covering at least a portion of the sealing member and at least a portion of the door frame, where a portion of the corner cover is embedded in the sealing member so that the inner cover and the sealing member form a unitary one-piece structure.
