PURPOSE:To promote the simplification of a structure by constituting the second power cylinder arranging only cylinder tubes in both end part positions of cylinder tubes of the first power cylinder, in the case of a device which performs steering action of large and small angles by the separate power cylinders. CONSTITUTION:This rear wheel steering power cylinder device A has the first and second power cylinders 21, 22, and providing a neutral holding mechanism, constituted of retainers 33, 33' and a spring 34, in the first power cylinder 21, cylinder tubes 36, 36', mounting a piston 42 to be fitted, are supported being able to generate the small displacement to a car body 38 by rubber bushes 37, 37'. Piston rods 35, 35' are connected to right and left rear wheels through a knuckle or the like. While providing cylinder tubes 39, 39', arranged in both end parts of the above described cylinder tubes 36, 36', in the second power cylinder 22, each cylinder tube 36, 36' serves for a piston of the second power cylinder 21, and oil chambers 22a, 22b are formed to the right and left of the piston. |
