Position adjustment type steering column device for vehicles

Abstract

A vehicular steering column system includes an outer column and an inner column which fits slidably in the outer column, whereby a relative position between the inner column and the outer column is adjusted by expanding and contracting the diameter of an inner circumferential surface of the outer column. An iron bush is provided between the inner circumferential surface of the outer column and an outer circumferential surface of the inner column in such a manner as to fit in or on at least the inner circumferential surface of the outer column or the outer circumferential surface of the inner column.
