Abstract

Official abstract text for this publication.

Construction is achieved that is capable of maintaining overall strength of a cylindrical-shaped steering column, while at the same time making it possible to make the thickness part of the steering column thin. An outer column 10 b , which is a column member of a steering column is formed by connecting in the axial direction a main portion 18 made using a light metal alloy with a cylindrical member 19 made of an iron-based alloy by a concave groove 20 that is formed around the outer circumferential surface of the front end section of the cylindrical member 19 engaging with a protrusion 21 that is formed around the inner circumferential surface of the rear end section of the main portion 18 . A ring 22 made using a metallic material is fitted and fastened inside the inner diameter side of the cylindrical member 19 in the connecting section between the main portion 18 and the cylindrical member 19.

First claim

Opening claim text (preview).

What is claimed is: 1. A manufacturing method of a steering column having a cylindrical shape as a whole and comprising a column member, the column member comprising: a main portion that is made using a light metal alloy, and comprises a convex section provided at one location or more in the circumferential direction on a circumferential surface on one end thereof; a cylindrical member that is made using an iron-based alloy, and comprises a concave section at one location or m…
