Abstract
Official abstract text for this publication.
A rotor of a rotating electric machine includes a rotor yoke and a pair of end plates disposed on both axial sides of the rotor yoke. The rotor yoke is provided with a yoke cavity portion axially passing through a yoke main body, end plate hole portions communicating with the yoke cavity portion are provided in the pair of end plates, the yoke cavity portion and the end plate hole portions have a substantially triangular shape protruding toward an outer-diameter-side, and in the yoke cavity portion, top portions on both circumferential sides and a top portion on an outer-diameter-side are exposed from the end plate hole portions.

The invention claimed is: 1. A rotor of a rotating electric machine comprising: a rotor yoke; and a pair of end plates disposed on both axial sides of the rotor yoke, wherein: the rotor yoke is provided with a yoke cavity portion axially passing through a yoke main body; end plate hole portions, communicating with the yoke cavity portion, are provided in the pair of end plates; the yoke cavity portion and the end plate hole portions have a substantially triangular shape protruding toward an outer-diameter-side; and in the yoke cavity portion, top portions on both circumferential sides and a top portion on an outer-diameter-side are exposed from the end plate hole portions. 2. The rotor of the rotating electric machine according to claim 1 , wherein: in the rotor yoke, a coolant flow path is provided further on an inner diameter side than the yoke cavity portion; and the coolant supplied to the coolant flow path is discharged from the end plate hole portions. 3. The rotor of the rotating electric machine according to claim 1 , wherein each of the end plate hole portions includes convex portions which respectively protrude inward between a top portion on an outer-diameter-side and top portions on both circumferential sides. 4. The rotor of the rotating electric machine according to claim 1 , wherein the end plate hole portions are outermost diameter side hole portions provided in the end plates. 5. The rotor of the rotating electric machine according to claim 1 , wherein in the pair of end plates, shaft insertion holes where a rotor shaft is inserted are provided and a hole portion is not provided except for the shaft insertion holes and the end plate hole portions.
