Abstract: When an adjustment lever 32 is rotated in order to adjust the position of a steering wheel 1, the adjustment lever 32 is prevented from vigorously rotating, which prevents making the driver who operates the adjustment lever 32 feel discomfort. An expandable damper 35 that provides resistance to the rotation of the adjustment lever 32 is provided between a protrusion 34 that rotates together with the adjustment lever 32 centered around an adjustment rod and an extending portion 37 that is provided on a support-plate portion 15c. The expandable damper 35 has a cylinder portion 38 and a damper rod 39 that are combined so as to be able to displace relative to each other in the axial direction by way of grease 40.

Abstract: Provided is a torque-transmission joint 15a that is able to reduce the thrust force that is transmitted between the output shaft 12a of an electric motor 8 and a worm shaft 6a without generating noise. A shock-absorbing member 18a that is made using an elastic material is assembled between a driving-side transmission member 16a that is supported by the output shaft 12a and a driven-side member 17a that is supported by the worm shaft 6a. Held sections 33a, 33b of the shock-absorbing member 18a are located between the side surfaces in the circumferential direction of driving-side arm sections 21a of the driving-side transmission member 16a and side surfaces in the circumferential direction of driven-side arm sections 23a of the driven-side transmission member 17a. A damper section 26 is integrally provided with the shock-absorbing member 18a, and that damper section 26 is elastically held between the tip-end surface of the output shaft 12a and the base-end surface of the worm shaft 16a.

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。
