ABSTRACT:
A drive control unit alone can be replaced without detaching an electric power steering apparatus from a gear housing. A motor housing of an electric motor, which outputs assist torque to a steering wheel of a vehicle, and a drive housing of the drive control unit, which controls the driving of the electric motor, are coupled to each other at a mating surface in a surface to surface contact manner, and the drive housing and the gear housing are coupled with each other on the same axis. A location of connection, at which a power supply input terminal block of the electric motor and power supply bus bars of the drive control unit are connected to each other by us of screws, is arranged at a joint location at which the motor housing and the drive housing are joined to each other by screws.
