Abstract: A steering apparatus includes an inner column, an outer column fitted onto the inner column, a vehicle body mounting bracket, a distance bracket fixed to the outer circumference of the outer column and slidably held between left and right side plates of the vehicle body mounting bracket, and a tightening rod. The distance bracket is formed with telescopic slots through which the tightening rod is inserted. The distance bracket includes left and right front tightening portions and left and right rear tightening portions. The axial distance between the pair of left and right front tightening portions and the pair of left and right rear tightening portions is shorter than the axial length of each telescopic slot. The outer column is formed with a pair of left and right through-holes into which the left and right front tightening portions or the left and right rear tightening portions is inserted.

Abstract: Construction of a steering column apparatus used in a tilt steering apparatus is achieved that is capable of reducing impact applied to the driver's body even when an adjustment rod is forcibly pressed against the front edges of long holes in the up-down direction during a secondary collision. Through holes that are continuous along the long holes in the up-down direction from the top end portion to the bottom end portion of the long holes in the up-down direction, and are formed in portions of a pair of left and right support plate portions of the support bracket that are further toward the front side than the long holes in the up-down direction. Bridge portions are provided between the front side edges of the long holes in the up-down direction and the rear side edges of the through holes. The bridge portions reduce impact by plastically deforming in the forward direction due to an impact load that is applied in the forward direction from the steering column by way of the adjustment rod during a collision accident.
Abstract translation: 实现了在倾斜转向装置中使用的转向柱装置的构造，即使在二次碰撞期间调节杆被强制地按压在上下方向上的长孔的前边缘的情况下，也能够减轻施加到驾驶员身体的冲击 。 沿着上下方向从上下方向的长孔连续的贯通孔，在上下方向从长孔的顶端部到底端部，并且形成在一对左右支撑板的一部分 支撑托架的一部分比上下方向上的长孔更靠前侧。 在上下方向的长孔的前侧边缘和通孔的后侧边缘之间设置桥接部。 由于在碰撞事故期间通过调节杆从转向柱沿向前方向施加的冲击载荷，桥接部分减小了向前方向塑性变形的冲击。

Abstract: A tilt-type steering apparatus includes a tilt lever, an expandable mechanism having a driving cam rotated by the tilt lever and a driven cam engaged with the driving cam, and a telescopic damper arranged to apply resistance against the rotation of the tilt lever in a direction allowing a position of a steering wheel to be adjusted. The telescopic damper is provided between a lever-side engaging portion which rotates together with the tilt lever and a cam-side engaging part of the driven cam.
