Embodiment Construction

[0025] Embodiments of the present invention will be described below with reference to the accompanying drawings. figure 1 is a partially cutaway schematic side view showing the schematic configuration of the steering system according to the first embodiment of the present invention. refer to figure 1 , The steering system 1 includes a steering shaft 2 , a steering column housing 3 , an intermediate shaft 4 and a steering mechanism 5 . Hereinafter, the upper side in the steering column axis direction X which is the axial direction of the steering shaft 2 will be referred to as the axial upper side XU, and the lower side in the steering column axis direction X will be referred to as the axial lower side. Side XL.

[0026] A steering member 6 such as a steering wheel is coupled to an end of the steering shaft 2 on the axially upper side XU. The steering system 1 changes the direction of steered wheels (not shown) according to the manipulation of the steering member 6 . The st...

Abstract

A steering system includes a column jacket (3) including a lower jacket (8) and an upper jacket (7); an engagement member (42); a retaining member (70); and a buffer member (80) that is retained by the retaining member (70) and contacts the engagement member (42) in a contact direction at a time when the upper jacket (7) is displaced to one sliding end. The retaining member (70) includes a support surface (70b) that supports the buffer member (80); paired holding portions (73) that are respectively disposed on both sides of the buffer member (80) in a circumferential direction of the upper jacket (7) and hold the buffer member (80) toward the support surface (70b); and a restriction portion (74) configured to be engaged with an end (80d) of the buffer member (80) on a side toward which an opposite direction is directed, so as to restrict movement of the buffer member (80) in the opposite direction, the opposite direction being opposite to the contact direction.

Description

technical field [0001] The invention relates to a steering system. Background technique [0002] In the steering system, a cushioning material is attached to one of a bolt shaft of a fastener realizing telescopic locking and a stopper plate facing the bolt shaft in the axial direction of the steering column tube. When the buffer material contacts the other of the bolt shaft and the stopper plate during the telescopic adjustment, the adjustment range of the telescopic adjustment is limited. Such a steering system has been proposed (for example, see Japanese Patent Application Publication No. 2014-24493 (JP 2014-24493A)). Contents of the invention [0003] In the case where a large impact is generated when the cushioning material contacts the other of the bolt shaft and the stopper plate, the cushioning material may come off from the one of the bolt shaft and the stopper plate, and therefore, the cushioning material cannot Stably absorbs the shock in the steering system de...
