A run channel in an automobile door includes a U-shaped run channel body. An inner lip extends from a bottom end portion of an inner wall of the run channel body towards a peak portion. An upper lip is formed above the inner lip and extends from an intermediate portion of the inner wall to the peak portion. When a door glass abuts on the inner lip, the door glass presses the inner lip towards the inner wall to cause a distal end portion of the inner lip to press on the upper lip, whereby a reaction force of the upper lip is applied to the distal end portion of the inner lip. The inner lip in turn produces a reaction force slowing upward movement of the door glass, causing its upper edge to slowly abut on the peak portion of the run channel, thus reducing a glass striking sound.
