Abstract:
1. A steering device comprising: an inner column; a hollow outer column that has an inner curved surface around an outer curved surface of the inner column so as to be capable of telescopic positioning and rotatably supports a steering shaft fitted with a steering wheel; a clamp unit that contracts and expands the inner curved surface of the outer column to clamp and unclamp the outer curved surface of the inner column at a specified telescopic adjustment position; a long hole that is formed in the outer column as long as a telescopic positioning range in an axial direction and is bored from an outer curved surface of the outer column to the inner curved surface of the outer column; a first through-hole that is formed in the inner column and is bored from the outer curved surface to an inner curved surface of the inner column in a radial direction; a stopper made of metal provided for the long hole including a side plate and a bottom plate, wherein the side plate has an oval shape and wherein the bottom plate covers a bottom face of the side plate; a second through-hole that is formed in the stopper and approximates to the first through-hole in diameter and wherein the second through-hole is disposed within the oval shape of the side plate; a slide member made of resin, wherein the slide member is pressed and fixed around the side plate of the stopper and wherein a lateral surface of the slide member is in contact with an inner surface of the long hole; and a blind rivet with a disk-shaped head section that is inserted from the outer curved surface of the outer column into the second through-hole and the first through-hole, exposes a tip of the blind rivet from the inner curved surface of the inner column, and expands the tip into a spherical bulged shape to fix the stopper to the outer curved surface of the inner column by strongly pressing the tip against the inner surface of the inner column.
