ROLLING BEARING

PROBLEM TO BE SOLVED: To provide a rolling bearing which has a constitution capable of removing a foreign substance existing inside the bearing.SOLUTION: A rolling bearing 100 includes a plurality of rolling elements 10, a cage 20, an inner ring 30, an outer ring 40, and a wiper 50. The cage 20 is arranged so as to hold the plurality of rolling element 10 with an interval from each other. The inner ring 30 is arranged inside the cage 20, and includes an annular inner ring raceway surface 32. The outer ring 40 is arranged outside the cage 20, and includes an annular outer ring raceway surface 42. The wiper 50 is mounted on the cage 20, in a region of the cage 20 sandwiched between a pair of adjacent rolling elements 10 out of the plurality of rolling elements 10. The wiper 50 is capable of coming into contact with at least one of the inner ring 30, the outer ring 40 and the rolling element 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、ワイパー５０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。ワイパー５０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。ワイパー５０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
