Claim:
1. A rotor for a rotating electric machine, comprising: a core body that has a plurality of through-holes passing through the core body in a thickness direction and arranged in a circumferential direction of the core body; plurality of magnets disposed on an outer wall of the core body and arranged in the circumferential direction of the core body; a tubular portion placed radially-outward of the core body such that an inner wall of the tubular portion contacts with the plurality of magnets; a first plate part that seals one end of the tubular portion in an axial direction of the core body; and a second plate part that seals an other end of the tubular portion in the axial direction, wherein each of the first plate part and the second plate part has an opening that passes through the first plate part and the second plate part in a thickness direction, the opening is located at a position corresponding to each of the plurality of through-holes and has a first edge and a second edge facing each other in the circumferential direction, the first plate part has the second plate part has a second blade portion that directly extends only from the second edge of the opening in the circumferential direction away from a surface of the second plate part, the first blade portion has a curved-plate shape and directly extends only from the first edge of the opening while being curved, the second blade portion has a curved-plate shape and directly extends only from the second edge of the opening while being curved, and the first blade portion or the second blade portion receives air in the circumferential direction and guides the air to flow into the plurality of the through holes when rotor rotates.
