摘要： An electric power steering apparatus having a compact and inexpensive backlash mechanism is provided by arranging its structure to easily adjust the backlash of the bevel gear mechanism, and at the same time, to pre-press the bearings so that the movement of the shaft in the axial direction can be regulated. The rotational shaft having a small gear coupled thereto which constitutes a bevel gear mechanism on one side is rotatively supported by a housing, but disabled to shift in the axial direction. The large gear which constitutes the bevel gear mechanism on the other side is coupled to the output shaft of a steering system so that it can shift in the rotational direction and axial direction together with the shaft. The output shaft is rotatively supported by bearings with respect to the housing with a movable sleeve which abuts upon the outer ring of the bearing. The movable sleeve can be driven in from the outside by means of an adjustment screw so that the backlash between the small and large gears can be adjusted, while the inner ring of the bearing can be driven in with respect to the output shaft by means of a lock nut to tighten the bearing which abuts upon the outer ring of the output shaft. In this way, the inner rings of the bearings are pressed inwardly themselves, hence removing the play thereof.

摘要： A rack shaft (110) is formed with a rolling face (110c) narrower than a face width of rack teeth (110a) on the opposite side with an axis line X of the rack shaft being interposed therebetween, and formed with a pair of oblique faces (110b) on both sides with the rolling face (110c) being interposed therebetween, there are further provided a cylindrical roller (123) rolling on the rolling face (110c) of the rack shaft (110) and a support device (120) pressing the cylindrical roller (123) toward the rack shaft (110), and hence the cylindrical roller (123) rolls on the rolling face (110c) when a steering force is transmitted to the rack shaft (110) from a pinion (103a), thereby making it possible to allow a movement of the rack shaft (110) in an axis-line direction with a smaller resisting force.

摘要： In an electric power steering apparatus in which steering torque applied on a steering wheel is detected by a torque sensor, and a steering assist torque is generated by an electric motor in accordance with the detected steering torque and transmitted to an output shaft of a steering mechanism with a speed reduced by a worm gear mechanism, the gear meshing position in the worm gear mechanism and the position of the torque sensor are arranged to be substantially coincide with each other with respect to the axial direction of the output shaft. Alternatively, a worm wheel of the worm gear mechanism is directly supported on a housing in a rotatable manner by means of a bearing. A steering shaft and an input shaft of a power assist section are fixedly connected in close contact attained by plastic deformation.
