Guide roller of sliding door for vehicle
The invention provides a guide roller of a sliding door for a vehicle, which can prevent peeling and cracking of a covering component. In a structure including two eccentric grooves (51a, 51b), even if an upper edge portion of a covering member (7) rolls while bearing a large load by contacting a guide rail member, an outer peripheral surface (50) of an outer ring (5) and the covering member (7) are less likely to slide and displace relative to each other about a rotation axis center (X0) of the outer ring (5), and the covering member (7) can be prevented from being peeled off from the outer peripheral surface (50) of the outer ring (5). Furthermore, a concentric groove (52) extending in the entire circumferential direction of the outer peripheral surface (50) of the outer ring (5) is formed between the two eccentric grooves (51a, 51b) on the outer peripheral surface (50) of the outer ring (5), so that the shear stress caused by the difference in the amount of elastic deformation is relieved, and breakage of the covering member (7) can be prevented.
本发明提供一种能防止包覆构件的剥离以及破裂的车用滑动门的导辊。在包括两个偏心槽(51a、51b)的结构中，即使包覆构件(7)的上缘部通过与导轨构件接触而在承受大的负荷的同时滚动，外圈(5)的外周面(50)和包覆构件(7)也不易绕外圈(5)的旋转轴线中心(X0)相对地滑动并移位，能防止包覆构件(7)从外圈(5)的外周面(50)剥离。此外，由于在外圈(5)的外周面(50)处的两个偏心槽(51a、51b)之间形成有遍及外圈(5)的外周面(50)的整个周向延伸的同心槽(52)，因此，由弹性变形量之差导致的剪切应力得到缓和，能防止包覆构件(7)的破裂。
