Abstract
Disclosed is a glass run for an automobile door which may block noise that has passed through a door glass from easily reaching the passenger's ears, while reducing an increase in the weight and cost of the glass run. In the glass run, a space R is formed between a base end portion 41b of an inner seal lip 41 located inside a cabin and an inner surface 22b of a door glass 22 facing inside the cabin. A facing surface 41d of the inner seal lip 41 facing the inner surface 22b of the door glass 22 is provided with a sound absorbing portion 41h which absorbs noise that has entered the inside of the cabin through the door glass 22.
