A power steering apparatus includes: a worm driven by a motor for assistance; a worm wheel engaged with the worm and transmitting an assist force to a steering shaft; a housing which houses the worm and the worm wheel; a plug having a male screw on an outer peripheral surface of the plug, the male screw being screwed with a female screw formed at the housing; an elastic member, one end of which in a biasing direction of the elastic member is supported by the worm and other end of which in the biasing direction is supported by the plug, giving a preload between the worm and the worm wheel; and a plug fixing member for fixing the plug, a position of which is adjusted to a screwing position at which the preload is a predetermined value, so that the plug is unrotatable with respect to the housing.
