する電動式動力舵取装置。 An electric motor is connected to an input shaft on the steering wheel side via a torsion bar and transmits rotational driving force to the output shaft system on the steering wheel side when steering is required, and an electric motor on a gear shaft that transmits the rotational driving force from this motor. A gear mechanism for transmitting steering assist force consisting of a transmission gear and a transmitted gear provided on the output shaft system, and a ball that rotatably supports a shaft member of the output shaft system having the transmitted gear in a steering body. The shaft member is interposed in the inner part of the shaft member of a ball bearing which is pivotally supported by the bearing and the shaft end of the shaft member of the output shaft system being fitted and held in a large bearing hole formed in the steering body. a spacer for adjusting the backlash of the gear mechanism for adjusting the position in the axial direction of the ball bearing; An electric power steering device characterized in that a hook engaging portion is provided in a portion corresponding to the annular groove on the outer circumferential portion of the outer ring of the body, on which a bearing pulling jig inserted from outside the body is hooked and locked.
