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.

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.

A plug is disclosed that reduces a potential for damage to a cap or bright strip of a weatherstrip assembly. The plug is preferably an elongated member having a cross-sectional first dimension that extends between and contacts an indented, transition region of the weatherstrip body and an inner surface of the cap.

A peel resistant weather strip lining a window frame of a vehicle to create a seal between a window and the window frame. The strip may have a body having an opening and configured to receive the window. The strip may further have a first flap extending around the body and configured to engage an exterior surface of the window frame. The strip may further have a second flap extending around the body and configured to engage an interior surface of the window frame. The strip may further have a catcher extending out from the second flap. The catcher may make direct contact with the interior surface of the window frame to prevent the second flap from disengaging the interior surface of the window frame when the strip is unwantedly rotated while holding, opening, or closing a door of the vehicle.

A glass run includes at least one of: an exterior sub-lip formed so as to project obliquely from an interior side of the exterior side wall that is closer to the bottom wall than a base portion of the exterior seal lip; an interior sub-lip formed so as to project obliquely in a direction toward a base portion of the interior seal lip from an exterior side of the interior side wall that is closer to the bottom wall than the base portion of the interior seal lip, the interior sub-lip formed with a thick portion on a base portion on a side of the interior seal lip; a thick portion formed on a base portion of the exterior seal lip; or a thick portion formed on a side of the interior seal lip that is not in contact with the door glass.

A channel according to an embodiment includes a first sidewall, a second sidewall, and an end wall. The first sidewall has a first end portion, a second end portion, and a first locking portion located between the first end portion and the second end portion to lock a glass run. The second sidewall has a third end portion, a fourth end portion, a second locking portion located between the third end portion and the fourth end portion to lock the glass run, and a fixing portion located between the fourth end portion and the second locking portion and configured to be fixed to a door constituting member. The end wall is connected to the first end portion and the third end portion. The fixing portion is located farther away from the first sidewall as the fixing portion is located farther away from the end wall.
