Patent ID: 8327584

Claim:
A glass run channel having an elongated shape, which is mounted on a run mounting portion of a window frame of a vehicle door, guides moving up and down of a windowpane and is made of a polymer material, the glass run channel comprising: a run channel main body that forms a main part of the glass run channel, the run channel main body including, a base bottom portion which is provided at a position facing an end surface of the windowpane, an interior side wall portion which extends from a width end of the base bottom portion, an exterior side wall portion which extends from another width end of the base bottom portion, an interior seal lip which projects toward the base bottom portion from an opening side end of the interior side wall portion and elastically contacts a first surface of the windowpane, an exterior seal lip which projects toward the base bottom portion from an opening side end of the exterior side wall portion and elastically contacts a second surface of the windowpane, an interior decoration portion which projects from the opening side end of the interior side wall portion toward an opposite side of the interior seal lip, and an exterior decoration portion which projects from the opening side end of the exterior side wall portion toward an opposite side of the exterior seal lip, wherein at least one of the interior side wall portion and the exterior side wall portion is made of a foamed polymer material, wherein an interior connecting portion connects the interior decoration portion and the interior seal lip, wherein an exterior connecting portion connects the exterior decoration portion and the exterior seal lip, wherein at least one of an interior covering layer that covers at least a portion of a first surface of the run channel main body, the first surface including a surface of the interior decoration portion and a surface of the interior connecting portion, and an exterior covering layer that covers at least a portion of a second surface of the run channel main body, the second surface including a surface of the exterior decoration portion and a surface of the exterior connecting portion, is formed, so as to cover a portion of the at least one decoration portion that is made of the foamed polymer material, and wherein the at least one covering layer is made of a second polymer material which has a foaming ratio smaller than that of the foamed polymer material or which is not foamed.
