ROLLER BEARING

PROBLEM TO BE SOLVED: To provide a roller bearing having a configuration capable of removing foreign material present in the bearing.SOLUTION: A roller bearing 100 comprises several rolling elements 10, cages 20, an inner ring 30, an outer ring 40 and fibrous members 50A. The cages 20 are arranged to hold the several rolling elements 10 while being spaced apart. The inner ring 30 is arranged inside the cages 20 and includes an annular inner ring raceway surface 32. The outer ring 40 is arranged outside the cages 20 and includes an annular outer ring raceway surface 42. The fibrous members 50A are fixed to the cages 20 at a region held between a pair of rolling elements 10 adjoining to each other of the several rolling elements 10 of the cages 20. The fibrous members 50A comprise a base material 51 and a fiber material 52 fixed to at least a part of the base material 51. The fibrous members 50A can be contacted with at least one of the inner ring 30, the outer ring 40 and the rolling elements 10.SELECTED DRAWING: Figure 1 【課題】軸受内部に存在する異物を取り除くことが可能な構成を備える転がり軸受を提供する。【解決手段】転がり軸受１００は、複数の転動体１０と、保持器２０と、内輪３０と、外輪４０と、繊維部材５０Ａとを備える。保持器２０は複数の転動体１０を互いに間隔をあけて保持するように配置される。内輪３０は保持器２０の内側に配置され、環状の内輪軌道面３２を含む。外輪４０は保持器２０の外側に配置され、環状の外輪軌道面４２を含む。繊維部材５０Ａは保持器２０の、複数の転動体１０のうち互いに隣り合う１対の転動体１０間に挟まれた領域において、保持器２０に取り付けられている。繊維部材５０Ａは、基材５１と、基材５１の少なくとも一部に取り付けられた繊維材５２とを含んでいる。繊維部材５０Ａは、内輪３０、外輪４０、転動体１０の少なくともいずれか１つに接触可能である。【選択図】図１
