PROBLEM TO BE SOLVED: To provide a rolling bearing provided with a flocked body in a bearing constituent, which can improve a lubrication characteristic containing excellent low torque.SOLUTION: A rolling bearing includes an inner ring and an outer ring 3 as a bearing ring, a plurality of balls interposed between the inner and outer rings, a holder 5 holding the balls, and lubricant supplied or sealed into a bearing inner space. The holder 5 has a flocked body 6 comprising a plurality of fibers fixed to an outer ring guide surface 5d; tip parts 6a of the fibers of the flocked body 6 contact with the outer ring 3 as a mating member; and the tip parts 6a of the fibers of the flocked body 6 are curved into a circular-arch shape.SELECTED DRAWING: Figure 5 【課題】軸受構成部材に植毛体を設けた転がり軸受において、優れた低トルク化を含む潤滑特性の向上を図り得る転がり軸受を提供する。【解決手段】この転がり軸受は、軌道輪である内輪および外輪３と、この内・外輪間に介在する複数の玉と、この玉を保持する保持器５と、軸受内空間に供給または封入される潤滑剤とを備え、保持器５は外輪案内面５ｄに固定された複数の繊維からなる植毛体６を有し、植毛体６の繊維の先端部６ａと、相手部材である外輪３とが接触し、植毛体６の繊維の先端部６ａが円弧状に湾曲している。【選択図】図５
