Problems solved by technology

Therefore, it is conceivable that the friction between the inner tube 104 and the energy absorbing portion 115 affects the absorption characteristics of the energy absorbing portion 115 for absorbing impact energy.
Due to variations in the abutment state, there will be differences in the absorption characteristics of impact energy for each product

Abstract

A steering apparatus is provided to stabilize absorption characteristics of impact energy. The steering apparatus (20) includes: an outer column (23) supported by a rack (21) and an inner pipe (24) retained by the outer column (23) for movement in a front-rear direction of a vehicle. An impact energy absorbing member (26) is disposed in the inner pipe (24) and has a generally U sectional shape along the axis line (C2) of the inner pipe (24). The impact energy absorbing member (26) includes an abuttable section (62) bent from the rear end of a base section (61) such that the abuttable section is abutted against a fastening mechanism (27); and an energy absorbing section (63) bent forward from one end of the abuttable section (62) such that the absorbing section absorbs energy of the impact while deforming.

Description

technical field [0001] The present invention relates to a steering device that has a telescopic adjustment mechanism and a shock absorbing mechanism during a secondary collision, and can share these mechanisms on the same component. Background technique [0002] Generally, there is known a steering device capable of adjusting the position of a steering wheel steered by a driver forward or backward. As one of such steering devices, there is a device in which an outer column is supported by a bracket, and a cylindrical inner tube is held by the outer column so as to be movable in the front-rear direction. As a conventional technology related to such a steering device, there is a technology disclosed in Patent Document 1. As shown in FIG. based on Figure 8 The technology disclosed in Patent Document 1 will be described. [0003] Figure 8 The steering device 100 of Patent Document 1 is shown in . In addition, the designations have been relabeled. refer to Figure 8 (a). T...
