PROBLEM TO BE SOLVED: To minimize the increase of the sliding resistance of a glass plate, even if foreign matter such as sand or dust is attached on the bottom surface of the door glass runner with which the end surface of the door glass plate of an automobile is slidingly brought into contact. SOLUTION: A plurality of grooves 4a, 4b, 4c extending in the longitudinal direction are formed in the bottom surface 31 of a door glass runner 3A at a prescribed intervals. Then, the cross-sectional areas of the respective grooves are successively set to be greater from the central groove 4a in the width direction to both side grooves 4b, 4c. Otherwise, the central part in the width direction of the bottom surface 31 of the door glass runner 3B is made to be a flat surface, and the grooves 4d, 4c are formed only in the parts on both sides. |
