Document Type and Number:
WIPO Patent Application WO/2018/021443
Kind Code:
A1
Abstract:
[Problem] To realize a structure capable of preventing improper wheel alignment even when a collision accident or an accident such as a steered wheel riding up on a curbstone occurs. [Solution] A male spline part 45 that is formed at one end section, in the axial direction, of an outer peripheral surface of an inner shaft 9a and a female spline part 23 that is formed on an inner peripheral surface of an outer tube 10a are subjected to spline engagement, thereby combining the inner shaft 9a with the outer tube 10a in a manner allowing a torque to be transmitted and in a manner allowing an increase/decrease in the entire length. At a section, of the inner shaft 9a, that is located closer to the other end in the axial direction than an edge of the outer tube 10a close to the other end in the axial direction, an inner-side small-diameter cylinder section 41 that has a smaller outer diameter than sections adjacent to that section at both sides in the axial direction is provided.
