Description
上記課題は以下の手段によって解決される。すなわち、第1番目の発明は、ロアーコラム、上記ロアーコラムに軸方向に相対的に摺動可能に嵌合されたアッパーコラム、上記アッパーコラムのアッパー側に設けられた転がり軸受によって上記アッパーコラムに回転可能に軸支され、車体後方側にステアリングホイールが装着される雌ステアリングシャフト、上記ロアーコラムのロアー側に設けられた転がり軸受によって上記ロアーコラムに回転可能に軸支され、上記雌ステアリングシャフトに軸方向に相対的に移動可能に、かつ回転トルクを伝達可能に係合して、上記ステアリングホイールの回転を車輪に伝達する雄ステアリングシャフト、上記ロアーコラムの内周面と雌ステアリングシャフトの外周面との間に介挿され、外周面には軸方向の中間部に環状凹溝を有し、内周面には軸方向の中間部に円筒面が形成されると共に、上記内周面の軸方向の両端部にテーパー面が形成され、かつ、軸方向の全長に渡って1個のスリットが形成された中空円筒状のブッシュ、上記ブッシュの外周面とロアーコラムの内周面との間に介挿され、上記雌ステアリングシャフトを、テレスコピック摺動を可能に、かつ、回転可能に軸支し、ブッシュを縮径する方向に付勢して、ブッシュの内周面を雌ステアリングシャフトの外周面に押圧する環状の弾性部材を備えたことを特徴とするステアリング装置である。 The above problem is solved by the following means. In other words, the first invention provides the upper column with a lower column, an upper column fitted to the lower column so as to be relatively slidable in the axial direction, and a rolling bearing provided on the upper side of the upper column. is rotatably supported, the female steering shaft to which a steering wheel is attached to the rear side of the vehicle body, the rolling bearing provided on the lower side of the lower column is rotatably supported on the lower column, to the female steering shaft A male steering shaft that engages so as to be able to move relative to the axial direction and transmit rotational torque to transmit the rotation of the steering wheel to the wheels, an inner peripheral surface of the lower column, and an outer peripheral surface of the female steering shaft interposed between, an annular groove in the middle portion in the axial direction on the outer peripheral surface, the inner peripheral surface Jikukata Together with the cylindrical surface is formed in the middle portion, in the axial direction of the inner peripheral surface end portions tapered surface is formed on, and the one over the entire axial length slit hollow cylindrical formed Bush, inserted between the outer peripheral surface of the bush and the inner peripheral surface of the lower column, and supports the female steering shaft to be telescopically slidable and rotatable, and to reduce the diameter of the bush The steering device includes an annular elastic member that is biased to press the inner peripheral surface of the bush against the outer peripheral surface of the female steering shaft.
