To provide a rotary electric machine comprising a bearing which has an improved to-be-cooled performance and is therefore suppressed in decrease of reliability, and a vehicle comprising the rotary electric machine.SOLUTION: A rotary electric machine 1 according to the present invention comprises: a stator 2; a bearing 10; and a shaft 8 which is a rotary shaft rotatably supported by the bearing 10, the rotary electric machine 1 further comprises: a. rotor 3 provided facing the stator 2; a lubricant holding unit 23 provided around the bearing 10 and filled with a lubricant to be supplied to the bearing 10; and a fan 20 generating cooling air for cooling the bearing 10. The bearing 10 comprises a shield member 12 only in the radial outside of the rotary electric machine. The lubricant holding unit 23 is provided only on the axial inner side of the rotary electric machine. The fan 20 is provided on the axial outside of the rotary electric machine with respect to the bearing 10.SELECTED DRAWING: Figure 3

    【課題】冷却性能が向上して信頼性の低下が抑制された軸受を備える回転電機と、この回転電機を備える車両を提供する。【解決手段】本発明による回転電機1は、固定子2と、軸受10と軸受10に回転可能に支持された回転軸であるシャフト8とを備え、固定子2と対向して設けられた回転子3と、軸受10の周囲に設けられ、軸受10に供給される潤滑剤が充填された潤滑剤保持部23と、軸受10を冷却するための冷却風を発生させるファン20とを備える。軸受10は、軸方向の機外側のみにシールド材12を備える。潤滑剤保持部23は、軸受10に対して軸方向の機内側のみに設けられる。ファン20は、軸受10に対して軸方向の機外側に設けられる。【選択図】図3
