Abstract: A steering column has an overall hollow and cylindrical shape at least part of which is formed using a column member. The column member includes a main body portion having one-side end section and the other-side end section and a cylindrical member having one-side end section and the other-side section. The cylindrical member is joined in the axial direction with respect to the main body portion by fitting and fastening the other-side end section of the cylindrical member inside the one-side end section of the main body portion. The inner diameter of the end surface of the other-side end section of the cylindrical member is smaller than the inner diameter of a portion of the other-side end section of the cylindrical member. The portion of the other end section of the cylindrical member constitutes a joined section between the main body and the cylindrical member.

Abstract: When adjusting the forward-backward position of a steering wheel, together with reducing any uncomfortable feeling experienced by the driver, a support bracket is prevented from breaking away toward the front due to an extremely large force applied during the adjustment operation. Elastic sleeves 35 are mounted inside the long holes 25a in the forward-backward direction, and an adjustment rod 19a is inserted through the inside of the elastic sleeves 35. Gaps 36 located between the outer circumferential surface of both end portions in the forward-backward direction of the elastic sleeves 35 and the inner circumferential surface of the both end portions in the forward-backward direction of the long holes 25a in the forward-backward direction. When adjusting the forward-backward position the steering wheel, the adjustment rod 19a forcibly displaces toward the end portions in the forward-backward direction of the long holes 25a in the forward-backward direction, and when forcibly colliding with the inner circumferential surface of the end portions in the forward-backward direction of the elastic sleeves 35, the gaps 36 reduce the impact that is applied to the inner circumferential surface of the end portions of the long holes 25a in the forward-backward direction from the adjustment rod 19a by increasing the amount that the end portions of the elastic sleeves 35 elastically deform.
Abstract translation: 当调整方向盘的前后位置时，与减少驾驶员感到的不便感觉相反，由于在调整操作期间施加极大的力，防止了支撑架向前方的分离。 弹性套筒35沿着前后方向安装在长孔25a内部，调节杆19a穿过弹性套筒35的内部插入。间隙36位于前后两端部的外周面之间 弹性套筒35的方向和长孔25a的前后方向上的两端部的内周面向前后方向。 当调整方向盘的前后位置时，调节杆19a朝向前后方向的长孔25a的前后方向的端部强制地移位，并且当强制地与前后方向的内周面碰撞时 弹性套筒35的前后方向的端部，间隙36通过增加从调节杆19a向前后方向施加到长孔25a的端部的内周面的冲击 弹性套筒35的端部弹性变形的量。
