て形成されたことを特徴とする動力舵取装置。 A valve sleeve rotatably fitted into a valve hole formed in the housing, and a valve rotor formed in the inserted portion inserted from an opening in the housing are rotatably fitted into the valve sleeve. An axial engagement groove is formed that is coaxially connected to the input shaft and that removably receives a pin that is press-fitted into the output end of the valve sleeve. In a power steering device comprising an output shaft integrally rotatably connected to a valve sleeve, a holding member is fitted onto the outer periphery of the input shaft so as to face an input side end surface of the valve sleeve, and the holding member and A pressure member such as a wave washer that presses the valve sleeve toward the output side in the axial direction is interposed between the thrust washer and the thrust washer that is brought into contact with the input side end face of the valve sleeve, and the engagement groove opens at the output shaft end face. A power steering device characterized in that the pin is formed as a tapered groove with a wide portion on the insertion side.
