A power steering device for a vehicle includes: a wheel-steering generator adapted to be connected to an axle case comprising a differential gear and a pair of right and left axles having a common axis; right and left steering knuckles adapted to be connected to the right and left axles, respectively, to attach right and left steering wheels thereto; right and left tie rods disposed between the right steering knuckle and the right piston rod and between the left steering knuckle and the left piston rod, respectively, to transmit force from the right and left piston rods to the respective steering knuckles, thereby steering the respective wheels; and right and left coupling members which couple the right and left tie rods with the right and left piston rods, respectively. The axis of the right and left piston rods is parallel to the axis of the right and left axles, and the right and left coupling members are disposed at positions such that the axis of each tie rod is positioned between the axis of the axles and the axis of the piston rods, thereby improving steering operation and the durability of the power steering device.
