ABSTRACT:
In an electric power steering apparatus that generates an auxiliary steering torque by a brushless motor in response to a steering torque applied on a steering wheel and transmits it to an output shaft of a steering mechanism while reducing it by means of a reduction gear, the apparatus comprises a rotor (10) to which a cylindrical permanent magnet for rotational driving (12) and a member to be detected (13) for detection of a rotational angle of the rotor are attached and a cylindrical stator (30) opposed to the rotor in which a laminated core (16) on which a coil is wound, detection means (17) for detecting the rotational angle of the rotor by the member to be detected and a terminal (19) for providing connection to the coil are integrally formed by resin molding. At least one bearing (8, 9) for rotatably supporting the rotor is disposed radially inside the stator and between the permanent magnet for rotational driving and the member to be detected.
