To provide a rolling bearing for achieving a reduction in the weight of drive units of an electric vertical takeoff/landing aircraft while enabling stable support of a rotary shaft over a long period.SOLUTION: Rolling bearings 11 are mounted on the electric vertical takeoff/landing aircraft provided with a plurality of drive units each having a rotary vane and a motor 5 for rotating the rotary vane, to fly with the rotation of the rotary vane. The rolling bearing includes: an inner ring 12; an outer ring 13; a plurality of rolling elements 14 laid between the inner ring 12 and the outer ring 13; and a retainer 15 holding the rolling elements 14. The rolling bearing supports the rotary shaft in the drive unit. At least one bearing member selected from the inner ring 12, the outer ring 13, the rolling elements 14 and the retainer 15 is formed of a metallic material which is lighter than an ironic material.SELECTED DRAWING: Figure 2

    【課題】電動垂直離着陸機において、駆動部の軽量化が図れるとともに、回転軸を長期において安定して支持可能な転がり軸受を提供する。【解決手段】転がり軸受11は、回転翼および該回転翼を回転させるモータ5を有する駆動部を複数備え、回転翼の回転によって飛行する電動垂直離着陸機に搭載され、内輪12と、外輪13と、内輪12および外輪13の間に介在する複数の転動体14と、これら転動体14を保持する保持器15とを備え、駆動部における回転軸を支持する軸受であり、内輪12、外輪13、転動体14、および保持器15から選ばれる少なくとも一つの軸受部材が鉄系材料よりも軽量な金属材料からなる。【選択図】図2
