A power steering device 100 includes: a steering shaft 2 that rotates under a steering torque input from the steering wheel 1; an electric motor 30 that applies a rotation torque for assisting the steering torque to the steering shaft 2; and a speed reduction unit 40 that decelerates the rotation of the electric motor 30 and transmits the decelerated rotation to the steering shaft 2. The steering shaft 2 includes a serration portion 14 and a tapered portion 15. One of a pinion gear 21 and a pitman arm 25 of the turning mechanism 20 is selectively coupled to the serration portion 14 by serration. The tapered portion 15 positions the pinion gear 21 in the radial direction by coming into contact with the pinion gear 21.
