する動力舵取装置。 An input shaft having one end connected to the steering handle and the other end inserted into the housing, a ball nut fitted to the input shaft via a number of balls, and engaging with a rack formed on the ball nut. a sector gear connected to the steering wheel via a link; and a control valve that is actuated by axial movement of the input shaft and switches a circuit to a hydraulic cylinder that applies power to the steering wheel; In a power steering device comprising an oil seal fitted between the outer surface of the input shaft and the inner surface of the housing to maintain liquid tightness in the housing, the portion of the inner surface of the housing where the oil seal is fitted. A large-diameter portion is formed closer to the inside, and a hydraulic damper is fitted between the input shaft outer surface and the large-diameter inner surface of the housing, and the hydraulic damper is sealed with an oil seal by the hydraulic pressure inside the housing. The outer circumferential side of the hydraulic damper is kept liquid-tight by being press-contacted to the step between the fitted part and the larger diameter part. A power steering device characterized in that a drain passage is formed in a housing to permit slight liquid leakage and communicate the space between the hydraulic damper and the oil seal to the outside.
