Summary:In a rotor for the dynamo, the interior circumference face of a rotor core main body makes contact in a thermally transmissible manner with a rotor axle, and the rotor axle includes a cooling medium circulation space. The rotor is provided with a cooling medium supply member, which supplies the cooling medium to the cooling medium circulation space. The cooling medium supply member is provided with a cooling medium supply path that extends in the rotor axle direction, and cooling medium supply holes that extend externally in the direction of the rotor diameter. The cooling medium supply holes are provided with supply apertures that open toward the cooling interior circumference face. The rotor axle is provided with cooling medium discharge holes that extend externally in the direction of the rotor diameter. The cooling medium discharge holes are provided with discharge apertures that open externally in the diameter direction.
