Abstract: <P>PROBLEM TO BE SOLVED: To provide an electric motor which can prevent excessive rotational torque from occurring in the rotor shaft by a simple structure.  <P>SOLUTION: Between a first bearing 15 for supporting the rotor shaft 13 of an electric motor 5 and a rear housing 20, an elastic member 80 consisting of a rubber or a metal spring deformable elastically in the radial direction is arranged. When "butting control" is performed at the "time of low temperature and high voltage" and an overload is applied to the rotor shaft 13, a twist force acting on the rotor shaft 13 increases and an eccentric force acting on the rotor shaft 13 also increases. Consequently, the rotor shaft 13 inclines by deforming the elastic member 80 elastically and the outer circumferential end of the rotor core 14 touches the inner circumferential end of the stator core 21. Since a part of torque generated from the electric motor 5 is received by a high rigidity stator core 21 through a high rigidity rotor core 14, rotational torque occurring in the rotor shaft 13 is suppressed and a drive object is not damaged mechanically.  <P>COPYRIGHT: (C)2009,JPO&INPIT
