A glass run includes a main body portion including a base bottom portion, a vehicle exterior side wall portion and a vehicle interior side wall portion attached along an inner periphery of a door frame and seal lips extended to an inner side of the main body portion and an entire region in a longitudinal direction thereof is formed by extrusion. The base bottom portion and the vehicle exterior side wall portion and the base bottom portion and the vehicle interior side wall portion are respectively connected by deformed connecting portions. The deformed connecting portion is thin-walled more than the base bottom portion and the two side wall portions and constitutes substantially a J-like shape in a section thereof to provide a predetermined length in a width direction. At two corner portions of the glass run, the deformed connecting portions are deformed by being folded to bend at fold points, the base bottom portion is smoothly disposed on an inner peripheral side, and is continuously bent without providing a slit or a notch.
