A structure of the steering column device for clamping the outer column to the inner column is simple and its manufacturing cost is reduced. The outer column 1 and the bushing are stopped against rotation to the clamp members and at the same time when the outer column is adjusted in its telescopic position in respect to the inner column, the outer column, clamp members and bushing can be integrally and axially slid. Since the bushing having a low frictional coefficient is present between the inner circumference of the outer column and the outer circumference of the inner column, the outer column can be moved with a light force in respect to the inner column.
