Abrégé
(EN) Disclosed is an electric motor rotor in which an insulating sleeve, which is applied on a shaft and insulates between the shaft and an antifriction bearing in order to suppress the electrolytic corrosion of the bearing, can be securely fixed by a simple method. The electric motor rotor (20) has a shaft (23) and a rotor resin magnet (22) that are integrated by means of a resin section (24), and an antifriction bearing that is disposed in the shaft (23), wherein the insulating sleeve (26) is provided between the shaft (23) and the antifriction bearing, and the insulating sleeve (26) is integrated and fixed by means of the resin section (24).
