する合成樹脂製の被覆部材８３０とを備えている。A conventional guide roller 8100 used as each of the above rollers is the guide roller 8100 shown in FIGS. 6 and 7. This guide roller 8100 is provided with a support shaft 880, a mounting hole 812 into which the support shaft 880 is inserted, and a ring-shaped inner ring 810 having a semicircular guide groove on an outer peripheral surface 811, and an inner ring having a larger diameter than the inner ring 810. A ring-shaped outer ring 820 having a semicircular guide groove on the peripheral surface 821.
And disposed between the guide grooves of the inner ring 810 and the outer ring 820,
A plurality of rolling elements 850 rotatably supporting the outer ring 820 with respect to the inner ring 810, and a synthetic resin covering member 830 for covering the outer peripheral surface of the outer ring 820 are provided.

という問題がある。However, in the above guide roller 8100, in order for the outer ring 820 covered by the covering member 830 to rotate smoothly with respect to the inner ring 810,
A slight gap k is required between the tip of the extending portion 832 of the covering member 830 and the corner portion of the inner ring 810, which is the opening, and cannot be completely sealed. Therefore, when ED coating is applied to the vehicle body that supports the slide door using the roller 8100, there is a problem that the ED coating material penetrates through the gap k to cause rotation failure. Further, in the guide roller 9100 described above, similarly, the roller core body 920
A gap is required between the support shaft 910 and the head of the support shaft 910 and cannot be completely sealed. Therefore,
When this guide roller 9100 is dipped in the ED paint, there is a problem that the paint adheres to the rolling elements 950 and rotation failure occurs.
