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 telescopic steering apparatus includes a steering column having an outer column and an inner column. An inner peripheral surface of the outer column has a supporting portion that supports the inner column. An inner peripheral surface of the outer column further has a shock absorbing portion at a location shifted toward one side in an axial direction from an axial end face of the inner column, a diameter of an inscribed circle of the shock absorbing portion being smaller than an outer diameter of the inner column. The outer column, including the supporting portion and the shock absorbing portion, and a movable bracket are integrally formed by an expansion forming.

Abstract: A torque transmission shaft includes a shaft and a clamp. The shaft includes: a male serration in one axial end portion; a slit in the other axial end portion, the slit axially extending and having a closed end on one side and an open end on the other side; a fitting cylinder portion in the other axial end portion; and a female serration provided in of the other axial end portion. The clamp includes: a discontinuous portion arranged at one place in the circumferential direction; a pair of flange portions arranged on both sides of the discontinuous portion; a connecting portion connecting the flange portions; and an insertion hole for fitting cylinder portion. The clamp is fitted onto the fitting cylinder portion to reduce the diameter of the fitting cylinder portion by narrowing the width dimension of the discontinuous portion.

Abstract: The shaft coupling structure includes: a male joint, and a female shaft that is coupled to male joint. The outer peripheral surface of the male joint has an outer peripheral side concave-convex portion having a concave-convex shape in the circumferential direction and an annular concave groove, and the inner peripheral surface of the female shaft has an inner peripheral side concave-convex portion having a concave-convex shape in the circumferential direction. The outer peripheral side concave-convex portion and the inner peripheral side concave-convex portion engage with a concave-convex engagement. The outer peripheral surface of the male joint and an end portion on one side of the female shaft in the axial direction are welded and fixed together, and an embossed portion provided on the inner peripheral surface of the female shaft is arranged on the inner side of the annular concave groove.

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.
