To provide a guide roller for a vehicle slide door, which can prevent peeling and cracking of a coating member.SOLUTION: In a configuration in which two eccentric grooves 51a and 51b are provided, even when the upper edge of a coating member 7 comes into contact with a guide rail member to roll while receiving a large load, an outer peripheral surface 50 of an outer ring 5 and the coating member 7 become difficult to be relatively slide-displaced about the rotational axis X0 of the outer ring 5, and the coating member 7 can be prevented from being peeled from the outer peripheral surface 50 of the outer ring 5. In addition, as a concentric groove 52 is formed between the two eccentric grooves 51a and 51b in the outer peripheral surface 50 of the outer ring 5 to extend over the full peripheral length of the outer peripheral surface 50 of the outer ring 5, shearing stress caused by a difference in elastic deformation amount is eased, and cracking of the coating member 7 can be prevented.SELECTED DRAWING: Figure 1

    【課題】 被覆部材の剥離および割れを防止することが可能な車両用スライドドアのガイドローラを提供する。【解決手段】 2つの偏心溝51a,51bを備える構成では、被覆部材7の上縁部がガイドレール部材と接触することで大きな負荷を受けながら転動されたとしても、外輪5の外周面50と被覆部材7とが外輪5の回転軸線中心X0周りに相対的に滑り変位し難くなり、被覆部材7が外輪5の外周面50から剥離することを防止することができる。また、外輪5の外周面50における2つの偏心溝51a,51bの間には、外輪5の外周面50の周方向全長に亘って延びる同心溝52が形成されているため、弾性変形量の差によるせん断応力が緩和され、被覆部材7の割れを防止することができる。【選択図】 図1
