Abstract:
1. A tilt steering assembly comprising a steering column permitting tilt adjustment about a tilt central axis, the tilt steering apparatus further comprising: at least one electrically conductive support shaft coaxial with the tilt central axis, electrical-conductively assembled to the steering column, and unitarily rotated with the steering column during the tilt adjustment; an electrically conductive end member provided at an end of the support shaft; an electrically conductive fixed side plate including a support hole for supporting the support shaft; and an electrically conductive member interposed between the fixed side plate and the end member, and having resilience for bringing the fixed side plate and the end member into electrical conduction; a bush formed of electrically insulative synthetic material and comprising a tubular portion and a flange disposed at one end of the tubular portion; wherein the tubular portion is interposed between an inner circumference of the support hole of the fixed side plate and an outer circumference of the support shaft, and the flange is interposed between the steering column and the fixed side plate; wherein the fixed side plate and the end member of the support shaft are spaced away from each other in an axial direction of the support shaft; and further comprising an electric steering-assist motor; wherein the electric motor includes a motor housing electrical-conductively mounted on the steering column; and wherein said steering column is grounded by means of the support shaft, the end member, the conductive member and the fixing side plate.
