Amendment April 4, 1983 The scope of claims for utility model registration is amended as follows.

[Claim for Utility Model Registration] A telescopic sleeve is axially connected to the end of a telescopic shaft on which a steering wheel is mounted, and a spline portion is carved in the axial direction on the inner peripheral surface of the telescopic sleeve. an upper shaft having a spline portion carved on the outer circumferential surface of the upper end portion that engages with the upper shaft portion is coaxially fitted in the axial direction, and a lower shaft that is contractably fitted to the lower end portion of the upper shaft; A telescopic core purge jacket that coaxially fits a telescopic shaft, a telescopic lower jacket that coaxially fits a telescopic shaft, and a column jacket that coaxially fits the lower shaft and upper shaft and is axially retractable. A telescoping type steering column comprising: a damper interposed between the upper shaft and the telescoping shaft on either one.

Claims (1)

[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 telescopic steering column characterized in that a damper is interposed between the upper shaft and the telescopic shaft by being fixed to either one of them.
