    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.

    摘要： A pinion shaft rotated by a steering wheel has a pinion gear formed thereon. A rack bar has at a front surface thereof a toothed rack portion meshed with the pinion gear of the pinion shaft. A rotating member is arranged to support a rear surface of the rack bar while being permitted to rotate when the rack bar moves axially. A biasing mechanism that biases the rotating member toward an actually meshed portion between the toothed rack portion and the pinion gear. A supporting member is arranged to slidably support the rear surface of the rack bar.

    摘要： A worm wheel is mounted to a steered shaft to rotate therewith. A brushless electric motor has an output shaft and is able to generate a power for assisting turning of the steered shaft when energized. A worm gear is coaxially connected to the output shaft of the motor to constitute a combined shaft structure. The worm gear is meshed with the worm wheel. Two bearings bear axially opposite end portions of the combined shaft structure respectively.
