Abstract:
A heat radiation base body extending in a direction of a rotation shaft of an electric motor close to the rotation shaft is provided at an end surface of a motor housing accommodating the electric motor. A board of one electronic control unit of a redundant system is fixed to the heat radiation base body along the direction in which heat radiation base body extends with thermal conduction allowed. A board of the other electronic control unit of redundant system is fixed to the heat radiation base body along a direction in which the heat radiation base body extends, so as to face the board of one electronic control unit, with thermal conduction allowed. A cover covering these is fixed to an end surface of the motor housing without a bolt. Thus, a housing accommodating the electronic control unit is not necessary. A sealing part is only the connecting portion between the motor housing and cover, thereby eliminating additional structure of the sealing part, sealing component required for seal and bolt.

Claim (Index 7):
An electric power steering device comprising:\n an electric motor providing a steering assistive force to a steering shaft on the basis of an output from a torque sensor that detects a turning direction and a turning torque of the steering shaft; a motor housing accommodating therein the electric motor; a heat radiation base body fixed to an end surface, which is an opposite side to an output shaft portion of a rotation shaft of the electric motor, of the motor housing and extending in a direction of the rotation shaft which is the opposite side to the output shaft portion; one electronic control unit of a redundant system, the one electronic control unit arranged along a direction in which the heat radiation base body extends and having a board that is fixed to the heat radiation base body with thermal conduction to the heat radiation base body allowed; the other electronic control unit of the redundant system, the other electronic control unit arranged along a direction in which the heat radiation base body extends and having a board that is fixed to the heat radiation base body with thermal conduction to the heat radiation base body allowed; and a cover covering the heat radiation base body and the one and the other electronic control units and liquid-tightly connected to the end surface of the motor housing without using a bolt.
