Japanese Patent JP2020111128
Kind Code:
A
Abstract:
To provide a rolling bearing device for a slide door in which a rail installation region passing through a space for boarding is small.SOLUTION: A rail 11 comprises a first load support surface 58a that receives a load in a vertical direction of a slide door 83 and a second load support surface 58b arranged translationally outside in a vehicle width direction of the first load support surface 58a. A guide roller 14 has a first outer peripheral surface 28 with a small diameter and a second outer peripheral surface 31 with a large diameter formed coaxially, which can freely rotate around a center shaft m, where a direction of the center shaft m can be changed around a shaft n in a vertical direction of a vehicle. The guide roller 14 rolls on the rail 11 in a state where the second outer peripheral surface 31 is not in contact with the second load support surface 58b and the first outer peripheral surface 28 is in contact with the first load support surface 58a when the slide door 83 is opened, and the first outer peripheral surface 28 is in contact with the first load support surface 58a and the second outer peripheral surface 31 is in contact with the second load support surface 58b when the slide door 83 is closed.SELECTED DRAWING: Figure 6
