ABSTRACT:
An impact energy absorbing member in which a plurality of impact absorbing plates are arranged with predetermined intervals along a direction in which a collapse stroke progresses is provided on either one of a vehicle side bracket or a column side bracket slidably fitted to the vehicle side bracket. On the other bracket, there is provided a breaking member for sequentially breaking said plurality of impact absorbing plates as the collapse stroke progresses. With this structure, the impact energy absorbing member is sequentially broken by the breaking member as the collapse stroke progresses upon secondary collision, so that impact energy is absorbed.
