Impact absorbing type steering column apparatus with a motorized power steering device.

摘要

In an impact absorbing type steering column apparatus with a motorized power steering device (112), a steering shaft (102) and a steering column (116) do not have their full lengths shortened even during a secondary collision. A housing (113) fixed to the fore end portion of the steering column (116) is supported on a vehicle body by an energy absorbing member (17). During a secondary collision, the energy absorbing member permits the forward displacement of the steering shaft (102) and steering column (116) while being plastically deformed. When the distance between a first (24) and a second (28) universal joint is shortened with the displacement, the full length of a transmission shaft (25) is shortened. <IMAGE>
