Claim Text:
1. An electric motor that is disposed adjacent to a housing of a rotated member serving as a load of the electric motor, the electric motor being configured to rotate the rotated member about a central axis of the rotated member, the electric motor comprising: a rotary drive shaft, a rotor rotatable with the rotary drive shaft; a stator fixed at a position radially outward of an outer periphery of the rotor; a flange portion that projects from an end face of the housing of the rotated member; a fixing member that is a metal member, the fixing member being fixed to a periphery of the stator of the electric motor, the fixing member having a first axial end and a second axial end; a holding member that is a metal member provided with a bearing that supports one side of a rotor of the electric motor; and a fastening member extending through the holding member and the fixing member in an axial direction and being fixedly received by the housing of the rotated member to couple the holding member to the housing of the rotated member by a fastening force, wherein the motor is fixed to the rotated member by the fastening force between the holding member and the housing of the rotated member, an outer periphery of the first axial end of the fixing member is fitted to an inner periphery of the flange portion, and an outer periphery of the holding member is fitted to an inner periphery of the second axial end of the fixing member, and a first end of the rotary drive shaft is supported by a first bearing in the housing of the rotated member, and a second end of the rotary drive shaft is supported by a second bearing in the holding member.
