において、前記ピストンの外周に、ステアリング
ロツドの曲げ変形をシリンダチユーブにより規制
するための受部材が設けられていることを特徴と
する油圧パワーステアリング装置。 The steering rod is provided with a steering rod that moves in the longitudinal direction in response to a steering operation, and a cylinder tube that is fitted onto the steering rod and supported on the vehicle body. An oil chamber is formed in the steering rod, and a piston is provided in the steering rod so that the pressure oil supplied to the oil chamber acts on the steering rod to assist in steering operation. In a hydraulic power steering device in which a seal ring is attached to the outer circumference of the piston to seal the space between it and the inner circumferential surface of the tube in an oil-tight manner, the cylinder tube prevents bending deformation of the steering rod from occurring on the outer circumference of the piston. A hydraulic power steering device characterized by being provided with a receiving member for regulating.
