PURPOSE:To prevent excessive stress from being applied, even when both shafts are placed in rough parallelism, by connecting a main drive shaft movable in an axial direction to a driven shaft parallelly arranged to the main this drive shaft through a connecting structure consisting of a turnable connecting unit and an elastic unit in a state to be connected in series to this connecting unit. CONSTITUTION:A front wheel steering power cylinder 14 of a four-wheel steering vehicle steers a front wheel through a tie rod 15 or the like swivelably connected to both ends of a piston rod 14b of the power cylinder 14, and interlocking to action of this power cylinder 14, a meter cylinder 19, parallelly arranged with the power cylinder 14, is operated. Right and left pressure chambers of the meter cylinder 19 are connected communicating with right and left pressure chambers of a rear wheel steering power cylinder. In this case, a bracket 36 is fixed to an end part of the piston rod 14b, while one end of an arm 37 is turnably connected to the point end of a piston rod 19b of the meter cylinder 19 through a bearing 38a. The other end of the arm 37 is connected to the bracket 36 through a shaft 40 and an elastic unit 41. |
