Abstract:
An automotive AC rotating machine comprising:a rotor which is fixed to a rotor shaft disposed in a bracket; a sun gear which is fixed to an end portion of said rotor shaft; a planet gear which meshes with said sun gear; a cylindrical member having an internal gear which meshes with said planet gear; a carrier which rotatably supports said planet gear via a planet gear shaft that axially passes through a center portion of said planet gear; a one-way clutch which is disposed in said carrier and which transmits a rotating force from a power transmission mechanism to said rotor shaft via said sun gear; and an electromagnetic clutch which is disposed in said bracket, wherein said one-way clutch and said sun gear are configured integrally with each other, wherein an inner periphery of a bearing is not fitted on an outer periphery of the carrier, wherein said power transmission mechanism, said one-way clutch, and said sun gear are configured integrally with each other as a sub assembly, and said planet gear and said carrier are configured integrally with each other as a sub assembly, and wherein, when said carrier and said power transmission mechanism are to be connected to each other, said carrier and said power transmission mechanism are subjected to radial positioning by coaxially fitting an outer periphery of one end portion of said power transmission mechanism and an inner periphery of said carrier.
