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

摘要

An impact absorbing type steering column apparatus with a motorized power steering device secures an amount of displacement in a secondary collision in spite of the presence of a housing for supporting an electric motor. A housing fixed to the fore end portion of the steering column is supported on a vehicle body by an energy absorbing member. During a secondary collision, the energy absorbing member permits the forward displacement of the steering shaft and steering column while being plastically deformed. When the distance between a first and a second universal joint is shortened with the displacement, the full length of a transmission shaft is shortened.
