Structure and Operation
• The steering gear is joined to the steering shaft through the intermediate shaft.
• In a collision, the intermediate shaft is crushed as the steering gear moves rearward, thereby absorbing the
impact.
• If the driver's body hits the steering wheel, the force applied to the steering wheel is transmitted through the
inner shaft, outer column, and fixing bracket. As a result, the fixing bracket is disengaged from the dashboard,
and the whole steering shaft will move forward. At this moment, the U-shaped plate, which is fixed to the
dashboard at one end and held by the fixing bracket at the other, will deform and absorb the impact.
