Shock-absorption steering apparatus

摘要

A shock-absorption steering apparatus (1) is provided which is capable of absorbing impact with a simple structure independently on a driving condition. A support pin for controlling the squeezing load to an energy absorption plate corresponding to its rotation is provided with a retainer. A slider is also provided, which can or cannot abut the retainer by moving up and down along with the drive of a motor. When the body weight of a driver (H) is a reference weight or more, the rotation of the support pin is restricted by driving the motor so as to allow the slider to abut the retainer. When the body weight is less than the reference weight, the support pin is enabled to rotate by driving the motor so as to separate the slider from the retainer.
