摘要:
A steering column support apparatus that is capable of simplifying tuning for stabilizing forward displacement of a steering wheel during a secondary collision, keeping material costs, processing costs and assembly costs of an energy absorbing member low, and when necessary, preventing the steering wheel from dropping down excessively during a secondary collision. A locking capsule 47 that is fastened to a bracket 3 on the column side is held inside a locking hole 45 of a bracket 11b on the vehicle side that is fastened to the vehicle body by a plurality of connecting members that shear during a secondary collision. An energy absorbing member 53 is placed between the locking capsule 47 and the bracket 11b on the vehicle side. This energy absorbing member 53 is formed by bending a plastically deformable wire, and allows forward displacement of the locking capsule while absorbing impact energy that is applied to the locking capsule by plastically deforming during a secondary collision.
