A glass run has extruded portions and molded portions. The extruded portions and the molded portions are made of TPO. The glass run is attached to sashes DS. Insert members made of PP are embedded respectively in a base portion of the glass run correspondingly to a long side portion and an upper side portion of each of the molded portions. When the glass run is attached, protrusions of the insert members protruding from the base portion can engage with or stand close to edge portions of the sashes so that the protrusions can be locked with the sashes. Since the protrusions are harder than the molded portions under a relatively high temperature atmosphere, the protrusions are hardly deformed or broken even when stress caused by opening and closing of a glass is applied repeatedly to the protrusions.
