Claims

[Scope of utility model registration request]

A telescopic sleeve is connected in the axial direction to the end of a telescopic shaft that pivotally attaches the steering wheel, a key lock groove is formed on the outer peripheral surface of the telescopic sleeve, and a spline portion is carved in the axial direction on the inner peripheral surface of the telescopic sleeve, In a telescopic steering column in which an upper shaft having a spline portion carved on its outer circumferential surface that engages with the spline portion is fitted coaxially so as to be slidable and rotatable in the axial direction, the upper shaft is fitted coaxially with the key lock groove in the radial direction. The groove in the spline portion of the opposing telescopic sleeve is formed to be shallower than the other grooves, and the spline portion of the upper shaft that is to engage with the shallow groove is formed with a protrusion lower than the other protrusions. A telescopic steering column that is characterized by
