A glass run that is fitted inside the doorframe of a motor vehicle reduces noise due to the use of a fine lubricant powder. The powder prevents noise of inner lips of the glass run. which strike and separate from inner walls of the glass run. The fine powder, such as silicon powder, polyaminde resin powder, molybdenum disulfide powder and fatty acid amide powder, is contained in the main body of an EPDM rubber or TPO in a dispersed condition. Alternatively, foam rubber layers may be formed on the inside walls to reduce noise.
