PROBLEM TO BE SOLVED: To provide an energy absorbing steering column enabling an upper shaft to move relative to an upper tube and enabling shortening of the axial length of the steering column.SOLUTION: An energy absorbing steering column includes: an upper shaft 1a which has a bearing 3 supported in an upper tube 10 and is rotatably supported in the upper tube via the bearing by which a steering shaft 1 is integrally held; and a lower shaft relatively movably supported relative to the upper shaft. Together with the bearing, the upper shaft is supported so as to be movable to the vehicle forward side relative to the upper tube by a predetermined distance. A press-fitting groove 10a, a step portion 10b and a lock portion (caulking portion 10c) are formed in the upper tube. The step portion inhibits the bearing from moving to the vehicle rearward side, and the lock portion inhibits the bearing from moving to the vehicle forward side.SELECTED DRAWING: Figure 3

    【課題】アッパチューブに対しアッパシャフトを移動可能とし、ステアリングコラムの軸方向長さの短縮化を可能とするエネルギー吸収ステアリングコラムを提供する。【解決手段】アッパチューブ10内に支持される軸受3を備え、ステアリングシャフト1が、軸受に一体的に保持され、この軸受を介してアッパチューブ内で回転可能に支持されるアッパシャフト1aと、アッパシャフトに対し相対移動可能に支持されるロアシャフトを具備し、アッパシャフトが軸受と共に、アッパチューブに対し車両前方側に所定距離移動可能に支持されている。アッパチューブには圧入溝10a、段部10b及び係止部(カシメ部10c)が形成され、段部によって車両後方側への軸受の移動が阻止され、係止部によって車両前方側への軸受の移動が阻止される。【選択図】図3
