In order to prevent charging of a shaft of a rotor, the rotor of the rotating electric machine includes a slip ring device composed of: a pair of slip rings; a pair of connection conductors electrically connecting the respective slip rings and a rotor coil; and an insulation molded body holding the slip rings and the connection conductors. In the insulation molded body of the slip ring device, the pair of slip rings and the pair of connection conductors are embedded and held such that the brush sliding surfaces of the slip rings and the lead-out-wire-connection end portions of the connection conductors are exposed in the 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.

A restricting member is provided that is in contact with respective bent lead portions of a long-sized lead and a short-sized lead and imparts a tension to linear lead portions thereof in a mold for insert molding. The restricting member reliably prevents the leads from displacement and deformation resulting from the pressure of the resin at the time of insert molding, and allows the long-sized lead and the short-sized lead to be disposed at proper positions in a molded body.

A slip ring device includes an insulating molded body in which a pair of slip rings and a pair of connecting conductors are provided. The insulating molded body includes a molded body main body portion disposed in a position further from a rotor main body than a bearing provided on a shaft, the slip rings being provided in the molded body main body portion, an opposing portion disposed between the bearing and the rotor main body, and a pair of beam portions that connect the molded body main body portion to the opposing portion, the connecting conductors being provided respectively in the beam portions. A pair of shaft grooves respectively accommodating the pair of beam portions are provided in the shaft. A spreading suppression portion for preventing resin with which a field coil is impregnated from spreading into the shaft grooves is provided in the opposing portion.

A primary molded body having an angled connector that is integrally connected to an insulating annular body provided in a stator of a motor section, and that has a plurality of terminals extending along an axial direction of the motor section; a through-hole that is formed in the primary molded body and runs through the angled connector from an interior of the insulating annular body; a secondary molded body that is molded so as to cover the primary molded body; a secondary molded connector that is formed in the secondary molded body and covers the angled connector; and a connector opening that is formed in the secondary molded connector and communicates with the through-hole, wherein an outlet of the through-hole communicates with the connector opening.
