Oil-cooling structure for magnets of motor, and motor

An oil-cooling structure for motor magnets, that includes: a pair of end plates that are disc-shaped and are mounted at both end portions of a rotor core; third oil paths formed at interiors of the end plates, and having axial direction portions that extend in an axial direction of a rotor shaft and are connected to axial direction end portions of second oil paths, respectively, and discharging portions that extend toward a radial direction outer side from axial direction outer side end portions of the axial direction portions and are open at end portions of the end plates; and angle mitigating members disposed in the third oil paths at corner portions formed by the axial direction portions and the discharging portions, configured to mitigate angles formed by the axial direction portions and the discharging portions in axial direction cross-sections that include the third oil paths.
