ABSTRACT

An actuator for steering rear wheels is reduced in size and its construction
is simplified while preventing a degradation in the reliability. An electric
coil 2 is disposed on the outside while a rotor is disposed on the inside,
assisting in heating dissipation. One of bearings 10 which support a rotor and
an electric coil 2 are integrally secured to a casing 1 when a resin 3 is
molded thereon. At the same time, a ring gear 12 is formed by the molding of
the resin 3. In addition, the molding operation of the resin forms one of sun
gears, 11a, integrally with a rotor 4. The casing 1 is formed with a recess or
projection 1a, 1b, thus preventing a slip of the resin member 3 from
occurring. A permanent magnet 13 which is separate from a permanent magnet 5
used for driving is mounted on the rotor.
