Steering apparatus

摘要

A steering apparatus is disclosed, the apparatus including: friction plates 23, 24a, 24b fastened by a fastening mechanism with a clamp portion and a vehicle-sided bracket 6; and an annular member 20 fitted on an inner column 3 and connected to the friction plates 23, 24a, 24b, the annular member 20 and the inner column 3 being formed with through-holes 20a, 3a penetrating the annular member 20 and the inner column 3 in the vicinity of a connecting portion between the friction plates 23, 24a, 24b and the annular member 20 and being connected by a pin 21 inserted into the through-holes 20a, 3a, the pin being fractured upon receiving predetermined impact force, resulting in canceling the connection between the annular member 20 and the inner column 3 to enable a more stable and lower separating load to be acquired.

1. A steering apparatus comprising:
a steering shaft transferring steering force; an inner column rotatably supporting the steering shaft; an outer column supporting the steering shaft rotatably and including a clamp portion clamping the inner column while being fitted on the inner column in a relatively movable manner in an axial direction; a vehicle-sided bracket pinching and fixing the clamp portion to a vehicle body; and a fastening mechanism fixing the inner column and the outer column by fastening the vehicle-sided bracket and the clamp portion in accordance with an operation of a user, then cancelling the fixation and thus enabling adjustments in tilt and telescopic directions of a steering wheel, wherein the steering apparatus further comprises: a friction plate fastened by the fastening mechanism together with the clamp portion and the vehicle-sided bracket; and an annular member being fitted on the inner column and connected to the friction plate, the annular member and the inner column are formed with through-holes penetrating the annular member and the inner column in the vicinity of a connecting portion between the friction plate and the annular member, and are connected by a pin inserted into the through-holes, and the pin is fractured upon receiving a predetermined level of impact force, resulting in canceling the connection between the annular member and the inner column.
