油圧式パワーステアリング装置。 The pinion shaft connected to the steering wheel side can be moved parallel to the rack connected to the steering link side, and the parallel movement of the pinion shaft during steering is transmitted to the input spool of the servo valve via a displacement magnification lever to activate the servo valve. In a hydraulic power steering device configured to switch over and apply hydraulic assist to the power cylinder accordingly, the displacement magnifying lever is rotatably fitted onto the pinion shaft at a base ring portion and attached to an intermediate pivot portion. A lever is swingably supported by the main body and linked to the input spool at its tip, and the lever is interposed between the lever and the main body near the intermediate pivot portion of the lever and is connected to the input spool from the input spool side. A hydraulic power steering device characterized in that a shaft seal is provided to prevent oil leakage toward the pinion shaft side.
