Claims (1)
ーを介しロータリーバルブに伝え、オイルポンプよりの
圧油をパワーシリンダーに選択的に給排して操舵し、且
つばねにより中立状態のトーションバーに予圧を与える
如くなした動力舵取装置に於て、入力軸外周に■溝を形
成し該■溝に対設した出力軸の透孔にボールを嵌合し、
出力軸外周に配設した円弧状又は環状ばねで該ボールを
■溝に圧接して中立状態のトーションバーに予圧を与え
る如くなしたばね反力装置。The movement of the steering wheel is transmitted to the rotary valve via the input shaft and torsion bar, pressure oil from the oil pump is selectively supplied to and discharged from the power cylinder for steering, and a spring preloads the torsion bar in its neutral state. In this power steering device, a groove is formed on the outer periphery of the input shaft, and a ball is fitted into a through hole in the output shaft opposite to the groove.
A spring reaction force device in which an arcuate or annular spring disposed around the outer periphery of the output shaft presses the ball against the groove to apply preload to the torsion bar in a neutral state.
