Abstract
An electric power steering device includes an output shaft connected to a steering mechanism of a steering system for power assisting the steering operation. The EPS includes a motor and a control circuit accommodated in a common motor housing. The motor housing comprises an end frame and a cup-shaped motor case hermetically covering the motor and the control circuit. The end frame is secured to a rack housing accommodating the steering mechanism, so that heat generated by the motor and the control circuit is transmitted to the rack housing.
