ABSTRACT:
A tilt steering column device includes a column tube assembly which comprises a lower column tube and an upper column tube. The column tube assembly is supported by a tilt center and tilt-lock means. A collar is provided at the tilt-lock means, and a guide bracket including an inclined surface and a holding support are fixed to an upper column tube. The collar has a front leg which is vertically held by the inclined surface and the holding support. By this structure, the column tube assembly can be vertically supported directly by the tilt-lock means without the intermediary of an energy absorbing bending bracket whereby the rigidity of the steering column is increased. The inclination of the inclined surface is near to the direction of the axis of the column tube assembly and thus the movement of the upper column tube is directed in the direction near to the axis of the column tube assembly. As a result, a degree of movement of the upper column tube is increased because the upper column tube does not interfere with the collar and the amount of an energy absorbed by the energy absorbing bending bracket is increased.
