Abstract
A glass run is made from TPO and includes a main body and a pair of sealing lips. The main body is provided with a base portion, exterior and interior side wall portions which both extend from the base portion. Parts of the glass run corresponding to vertical side parts of a door glass opening are extruded such that portions of the sealing lips for contacting with a door glass are covered by lip sliding portions. The lip sliding portions are made from an olefin composition compounded of polyolefin resin beads. At least a portion of the base portion for contacting with an edge of the door glass is covered by a base sliding portion. The base sliding portion is made from an olefin composition which is harder than the base portion and is not compounded of the resin beads.
