ROLLING BEARING

To provide a rolling bearing which enables improvement of a function for discharging lubrication oil in an annular space.SOLUTION: A rolling bearing 10 includes an inner ring 11 which integrally rotates with a rotary shaft 8, an outer ring 12, multiple conical rollers 13, and an oil discharge part 15 which is provided at one axial side of the inner ring 11 and rotates with the inner ring 11. The oil discharge part 15 has: a discoid wall part 16 which partially covers an annular space 29 formed between the inner ring 11 and the outer ring 12; and multiple blade parts 17 which are provided on a side surface 18 of the wall part 16 and rotate with the inner ring 11 to cause lubrication oil to flow in a direction of at least one of the radial inner side at which the lubrication oil flows to the rotary shaft 8 side, the radial outer side, and one axial side.SELECTED DRAWING: Figure 1 【課題】環状空間の潤滑油を排出する機能を高めることが可能となる転がり軸受を提供する。【解決手段】転がり軸受１０は、回転軸８と一体回転する内輪１１、外輪１２、複数の円すいころ１３、及び、内輪１１の軸方向一方側に設けられ内輪１１と共に回転する油排出部１５を備えている。油排出部１５は、内輪１１と外輪１２との間に形成されている環状空間２９を部分的に覆う円板状の壁部１６と、壁部１６の側面１８に設けられ内輪１１と共に回転することによって回転軸８側に向かう径方向内方、径方向外方、及び軸方向一方のうちの少なくともいずれかの方向に潤滑油を流す複数の羽根部１７とを有している。【選択図】 図１
