To provide a rotating electric machine capable of removing heat from a magnet in a high rotation region while improving fuel efficiency in a low/medium rotation region, and a vehicle equipped with the same.SOLUTION: A rotating electric machine 100 includes: a rotor 120; a rotating shaft 110 located in the center of the rotor 120; an axial cooling path 111 inside the rotating shaft 110, extending in the axial direction and sending a refrigerant to the rotor 120 in response to refrigerant supply; a refrigerant passage 122 provided in the rotor 120 so as to allow the refrigerant to flow from the axial cooling path 111; and a storage unit 112 located between the axial cooling path 111 and the refrigerant passage 122, receiving and storing the refrigerant from the axial cooling path 111 and sending the refrigerant to the refrigerant passage 122 by centrifugal force. The storage portion 112 is formed in a tapered shape that increases in diameter toward the refrigerant passage 122.SELECTED DRAWING: Figure 2

    【課題】低・中回転領域で燃費を向上させつつ、高回転領域では磁石の抜熱を図ることができる回転電機およびこれを備えた車両を提供する。【解決手段】回転電機100は、ロータ120と、ロータ120の中心に配置される回転軸110と、回転軸110の内部にあって、軸方向に延在し冷媒の供給を受けてロータ120へ冷媒を送る軸心冷却路111と、軸心冷却路111からの冷媒を流すようにロータ120に設けられた冷媒路122と、軸心冷却路111と冷媒路122との間にあって、軸心冷却路111からの冷媒を受けて貯留しつつ遠心力で冷媒を冷媒路122に送出する貯留部112と、を備え、貯留部112は、冷媒路122に向けてその径を大きくするテーパ形状に形成されている。【選択図】図2
