  • Patent number: 6688644
    Abstract: With the steering apparatus, a tilt can be adjusted by sliding a column bracket, which is fastened to a column housing supporting a steering shaft so as to be rotatable, along tilting apertures provided at side walls of a tilting bracket. A contact projection which is projected toward a stopper from a substantially center portion of the column bracket for limiting a tilt angle crashes into the stopper with a slide of the column bracket caused by a secondary crash and pushes the stopper into guiding apertures arranged in an extension to the tilting apertures. The steering apparatus can realize absorption of energy of a secondary crash by increasing a tilt angle always under a proper condition, while high accuracy is unnecessary in shaping related parts.
