ELECTRIC POWER STEERING DEVICE

Japanese Patent JP3772986

B2

PROBLEM TO BE SOLVED: To provide an electric power steering device 1 which is miniaturized with the wiring simplified, and at the same time, with a reduction in electric wave noises, and of which the reliability is high.
SOLUTION: In this EPS 1, a control circuit 9, an electromagnetic clutch and a steering angle sensor are integrated with a motor and housed in one motor housing 10. The motor housing 10 comprises an end frame 11 to which respective constituent parts are attached, and a cup-shape motor case 12 which is airtightly attached to the end frame 11, and the end frame 11 is fixed to a rack housing 13 of a steering mechanism. The motor and the control circuit 9 which are main heating parts among respective constituent parts, are respectively attached to the end frame 11 made of aluminum in a manner to radiate heat, and the heat transmitted to the end frame 11 is discharged into air by being further transmitted to the rack housing 13.
