Abstract
An impact absorption type steering column apparatus for an automotive vehicle is constructed so that a car body sided bracket secured to a car body is press-fitted to a column sided bracket provided separately from or integrally with a steering column, the steering column is supported by inserting a bolt through through-holes formed in the two brackets, and, when a secondary collision happens, an impact energy thereof is absorbed in a way that causes a flexural deformation of the car body sided bracket while moving the steering column towards the front of the automotive vehicle. In this apparatus, the through-hole of the column sided bracket is formed as an elongate hole extending to the rear side of the automotive vehicle from a position of the bolt.
