摘要： Disclosed is a coupling structure of a bearing for an EPS motor to eliminate a gap caused by a tolerance between the bearing and a pocket of a housing of the EPS motor, thereby improving assembling precision and reducing noise, the coupling structure supporting rotation of a rotating shaft through the bearing coupled to a lower portion of the housing and including a bearing pocket bent upwards from a lower surface of the housing and having a cylindrical space to support an outer circumference of the bearing at an inner wall thereof, whereby a gap between the inner wall of the bearing pocket and the outer circumference of the bearing is eliminated by deforming the inner wall towards an inner circumference thereof by caulking, coupling force between the bearing and the housing can be increased, and thereby reliability in assembly and operation of the motor is improved.
