Abstract
An electric steering apparatus designed to eliminate backlash by enabling a hypoid pinion , which operates with rotation of a steering assisting motor, to swing with a bearing as a fulcrum and deflecting the hypoid pinion in a radial direction by an elastic member . With this electric steering apparatus, it is possible to satisfactorily eliminate backlash without being affected by dimensional errors of parts such as gears used for assisting steering and to automatically eliminate backlash if it is caused by an increase of abrasion of teeth of the gears.
