Patent ID: 7475755

Claim:
An electric power steering device comprising: a rack shaft engaged with a steering pinion and constructed to be movable reciprocatively to follow rotational motion of the steering pinion; a rack housing receiving the rack shaft to be movable therein; a sleeve taking a generally cylindrical shape and arranged coaxially around the rack shaft through a ball screw mechanism formed externally of the rack shaft; a brushless motor taking a generally cylindrical shape, arranged almost coaxially between the rack housing and the sleeve and constructed to rotate the sleeve; and a rotational angle sensor received inside the rack housing and constructed to detect the rotational angle of the brushless motor, wherein the rack housing has arranged thereon a power connecter containing power terminals for supplying electric power to the brushless motor and a sensor connecter containing output terminals for outputting a detection signal of the rotational angle sensor, and wherein the power connecter and the sensor connecter are arranged to be on the same side in the axial direction of the rack shaft with respect to the brushless motor.
