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

    【課題】乗車空間を通過するレール設置領域が小さいスライドドア用転がり軸受装置を提供する。【解決手段】レール11は、スライドドア83の上下方向の荷重を受ける第1荷重支持面58aと、第1荷重支持面58aの車幅方向外側に並進して配置される第2荷重支持面58bを備える。ガイドローラ14は、小径の第1外周面28と大径の第2外周面31とが同軸に形成され、中心軸mの周りで回転自在であり、中心軸mは車両上下方向の軸nの周りで向きが可変である。ガイドローラ14は、スライドドア83の開放時には、第2外周面31と第2荷重支持面58bが非接触で、かつ、第1外周面28と第1荷重支持面58aが接触し、スライドドア83の閉鎖時には、第1外周面28と第1荷重支持面58a、及び、第2外周面31と第2荷重支持面58bが共に接触してレール11上を転動する。【選択図】図6
