To achieve low manufacturing costs by making a structure of a center part of a load support rolling bearing into a simple combination.SOLUTION: A bearing device for a slide door allows a slide door to move along a body side surface of a motor vehicle and includes: a shaft part 40 which is disposed connecting to the slide door and is placed having a physical relationship parallel to a load support raceway surface 18 of a guide rail; an annular inner member 36 which fits on the shaft part 40 and has an inner ring raceway surface 48 on an outer peripheral surface 52; an annular outer ring member 34 having an inner peripheral surface 50 which has a curved cross section so that rolling elements 38 may rotate around a rotation center point X1 set on an axis X of the shaft 40 and a curved outer peripheral surface 52 which may roll on the load support raceway surface 18; and the multiple rolling elements 38 disposed between the inner ring member 36 and the outer ring member 34.SELECTED DRAWING: Figure 3

    【課題】荷重支持用転がり軸受の中心部の構成を単純な組合せ構成とすることにより、製作コストを安価とする。【解決手段】自動車のボデー側面に沿ってスライドドアが移動するスライドドア用軸受装置であって、スライドドアに連結して配設され、ガイドレールの荷重支持軌道面18に対して平行な位置関係として配置された軸部40と、軸部40に外嵌して、外周面52に内輪軌道面48を有する環状の内輪部材36と、転動体38が軸部40の軸線X上に設定された回動中心点X1を中心として回動可能に断面が湾曲形状の内周面50と、荷重支持軌道面18を転動走行可能な湾曲形状の外周面52とを有する環状の外輪部材34と、内輪部材36と外輪部材34との間に介在する複数の転動体38と、を備える。【選択図】図3
