A power steering device for a vehicle having a tilt performance reducer is provided to absorb a shock transmitted from a worm wheel to a worm shaft when the worm shaft moves to shaft direction, by supporting the worm shaft with an elastic member. A power steering device for a vehicle comprises a reducer(2), an ECU(3), and a tilt performance device(11). The tilt performance device has a displacement bearing(20) and an elastic member. The displacement bearing supports a worm shaft(6) to move a center line of the reducer of the worm shaft which is meshed with a worm wheel(7). The elastic member moves a worm shaft bearing(12) to shaft direction from opposite side of the displacement bearing and surrounds the worm shaft bearing.
