PROBLEM TO BE SOLVED: To provide a low cost vibration control sash roller of simple structure, capable of surely preventing the vibration of a sliding door during moving. SOLUTION: A unit U comprises an elastic member 13 made of polyurethane, for example intervening between the outer ring 9 of a roller bearing 7 through which a mounting shaft 6 is inserted and a ring-like metal cover member 14. When molding a plastic wheel 4 rolling on the orbit face 3 of a sash roller rail 2, the cover member 14 of the unit U is inserted in and fixed to the inner periphery section of the wheel 4. Even if the wheel 4 is vibrated while being moving, this vibration is damped by the elastic member 13, which makes it hard to transmit this vibration to a sliding door. As a result, the vibration and noise generated in the sliding door can be restrained. Since the unit U can be used in common for wheels of various specifications, production costs can be reduced as a whole.
