Abstract: An electric power steering apparatus capable of being both lightweight and rigid. A lightweight electric power steering apparatus is achieved wherein a gear housing (45) that houses an electric assist mechanism, a lower support bracket (54) for fastening the gear housing (45) to the vehicle body, a sensor housing (56) that houses a torque sensor (57), an outer column (30) of a steering column (6c), and an upper support bracket (59a) for fastening the middle section of the outer column (30) to the vehicle body can all be integrally formed of synthetic resin, improving the strength of the joined sections of these members.

Abstract: A torque transmission joint has a shock-absorbing member between a drive shaft and a driven shaft. When the drive shaft is rotated in one direction, forces due to torque transmitted from the drive shaft to the driven shaft act inward in a radial direction of the shock-absorbing member on held sections that are held between one side surfaces in the circumferential direction of drive-side arm sections that are positioned in the front side in the one direction of rotation of the drive shaft, and side surfaces in the circumferential direction of driven-side arm sections that are positioned on the rear side in the one direction of rotation of the drive shaft.

Abstract: A shock-absorbing member 18a comprises combined held sections 33 that are located at a plurality of locations in the circumferential direction and that comprise paired held sections 25a, 25b that each have a mirror symmetry about an imaginary plane that passes through the center axis of the shock-absorbing member 18a and that are inclined in a direction toward the imaginary plane with respect to the radial direction as going toward the outside in the radial direction. Side surfaces 29a, 30a in the circumferential direction of the drive-side arm sections 21a and the driven-side arm sections 23a that are positioned at the front in the direction of rotation of the drive shaft 12a are inclined in a direction toward the front in the direction of rotation with respect to the radial direction as going toward the outside in the radial direction; and when the drive shaft 12a is rotated and driven, forces inward in the radial direction of the shock-absorbing member 18a act on the held sections 25a that are held between the side surfaces 29a in the circumferential direction of the drive-side arm sections 21a that are positioned in the front in the direction of rotation and the side surfaces 30b in the circumferential direction of the driven-side arm sections 23a that are positioned in the rear in the direction of rotation.

Abstract: A shock-absorbing member comprises held sections located at a plurality of locations in a circumferential direction and comprising paired held sections and non-paired held sections, and is constructed to have a non-circular cylindrical shape in cross-section. Portions where outer-diameter side end sections of held sections that are adjacent to each other in the circumferential direction are made continuous by way of outer-diameter side cover sections, and portions where inner-diameter side end sections of held sections that are adjacent to each other in the circumferential direction are made continuous directly or by way of inner-diameter side cover sections, in an alternating sequence in the circumferential direction. Drive-side arm sections are placed between the non-paired held sections, driven-side arm sections are placed between the paired held sections, and the outer circumferential surfaces of the drive-side arm sections are covered by the outer-diameter side cover sections.
