Rotor of rotating electric machine and rotating electric machine

9] A rotor of a rotating electric machine, comprising:

• a shaft rotatable about an axis;
• a rotor body having a rotor coil and fixed to the shaft;
• a pulley which is attached to one end of the shaft and to which a drive force from an engine is transferred;
• and
• a slip ring device including a pair of slip rings, a pair of connection conductors electrically connecting the respective slip rings and the rotor coil, and an insulation molded body attached to another end of the shaft and holding the slip rings and the connection conductors, wherein
• in the insulation molded body, the pair of slip rings and the pair of connection conductors are embedded and held such that brush sliding surfaces of the slip rings and lead-out-wire-connection end portions of the connection conductors are exposed in an outer circumferential direction, and
• at least one of the negative-side slip ring and the negative-side connection conductor embedded and held in the insulation molded body has a protrusion extending toward the shaft and electrically connected to the shaft.
