Claims

[Scope of utility model registration request]

A telescopic sleeve is connected in the axial direction to the end of the telescopic shaft that pivots the steering wheel, and a spline portion is carved in the axial direction on the inner peripheral surface of the telescopic sleeve, and a spline portion that engages with the spline portion is formed. An upper shaft engraved on the outer peripheral surface of the upper end portion is coaxially fitted in the axial direction, and a lower shaft is contractably fitted to the lower end of the upper shaft, and the telescopic shaft is fitted coaxially. In a telescopic steering column equipped with a telescopic core purge jacket, a telescopic lower jacket into which the telescopic core purge jacket is coaxially fitted, and a column jacket into which the lower shaft and upper shaft are coaxially fitted and which can be contracted in the axial direction. , a stepped portion is formed at the end of the telescopic purge jacket, an aviator made of an annular elastic body is fitted and fixed to the stepped portion, and when the ariviator comes into contact with the end surface of the telescopic purge jacket, A telescopic steering column characterized in that a constant gap is formed between an upper shaft and a telescopic shaft.
