<p><P>PROBLEM TO BE SOLVED: To provide an electric motor with a gear mechanism preventing vibration due to torque ripples generated in the electric motor or electromagnetic vibration thereof from being transmitted to a gear shaft when the gear shaft and a rotating shaft of the electric motor are integrally formed, and simplifying the configuration and improving a ratio of reducing a shaft direction length; and to provide a power steering device using the electric motor. <P>SOLUTION: A rotating shaft portion 31a of an outer rotor 31 is supported on one end of the gear shaft 13d whose one end is rotatably supported by a motor frame 21 attached on a gear housing 13a and the other end having a gear 13c extending in the gear housing 13a, a stator 32 is disposed facing the outer rotor 31 on the motor frame 21, and a vibration buffering member 25 is disposed between the gear shaft and the rotating shaft portion of the outer rotor. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
