摘要： A power steering apparatus includes a worm wheel mounted on the steering shaft, a worm shaft engaged with the worm wheel, a gear housing having a wheel accommodating portion to accommodate the worm wheel and a shaft accommodating portion to accommodate the worm shaft, a bearing mounted on the worm shaft to rotatably support the worm shaft, a holder disposed in the shaft accommodating portion and having a bearing retaining portion to retain the bearing and a resilient element disposed in the shaft accommodating portion and having a resilient body portion formed with a curvature. The resilient body portion is so structured as to become deformed in such a manner as to increase or decrease in diameter when the bearing shifts in a direction that moves the worm shaft away from the worm wheel and bias the bearing in a direction that urges the worm wheel toward the worm wheel.
