End portions of lower-side telescopic friction plateswhich lie to face a front side of a vehicle body are connected integrally by a connecting portion, and a lower endof the connecting portionis fixed to an outer circumference of an upper-side lower columnA by means of welding. When an upper columnis fastened on to a vehicle body mounting bracketfor tilt and telescopic positioning of the upper column, the lower-side telescopic friction platesand upper-side telescopic friction platesare fastened together. The upper columnand the lower columnare connected together via the lower-side telescopic friction platesand the upper-side telescopic friction plates, whereby the rigidity and vibration properties of a steering apparatus as a whole are enhanced.

Steering apparatus

A steering intermediate shaft has an inner shaft member and an outer tube member so engaged with each other as to be capable of transmitting rotation and to be slidable in an axial direction. The outer tube member includes slits so formed at one end as to extend in the axial direction. An annular fastening member is provided at a portion of the outer tube member formed with the slits to exert a fastening action inwards in a radial direction. The fastening member includes a disengagement preventing member for preventing the outer tube member from disengaging from the inner shaft member against an axial force within a predetermined value by engaging with the inner shaft member.
