Claims

[Scope of utility model registration request]

A tilt-type steering system in which the steering column is attached to the vehicle body, with the rear part being able to rotate up and down around a rotational fulcrum on the front side, and the mounting angle of the steering wheel can be adjusted up and down. In the apparatus, guide brackets are provided on the steering column in correspondence with a front side bracket and a rear side tilt bracket for attaching the steering column to the vehicle body, respectively, and a guide bracket is provided at the rear end portion of these guide brackets in the axial direction of the steering shaft. A guide groove is provided extending in the direction along the front side bracket and the rear side tilt bracket, and the guide groove is always inserted into the guide groove of the guide bracket and is inserted into the steering column from the rear end side. Each pin is provided with a locking/disengaging pin that separates from the guide groove of the guide bracket in the event of an emergency when an impact force is applied, and is formed by a tension spring, one end of which is fixed to the tilt bracket, and the other end of which is fixed to the tilt bracket of the steering column. a shock absorbing member that is fixed to a portion in front of the connection portion with the tilt bracket and absorbs the impact force acting on the steering column by a tension spring force when the locking pin is disengaged from the guide groove of the guide bracket; A steering device characterized by being provided with.
