Steering apparatus

摘要

A steering apparatus is disclosed, the apparatus including friction plates 23, 24a, 24b clamped by a clamping bolt 10 together with a clamp portion and a vehicle-sided bracket 6 to extend toward a rear side of a vehicle in an axial direction; and a holding member 20 fitted on an inner column 3 and connected to portions, on the rear side of the vehicle, of the friction plates 23, 24a, 24b, the holding member 20 and the inner column 3 being connected together via shearing pins 21a, 21b, the shearing pins being sheared into fracture upon receiving a predetermined level of impact force to enable a more stable and lower separating load to be acquired.
