Abstract
A collapsible steering column apparatus of a motor vehicle including a steering wheel made of a material whose stiffness is increased while the inside thereof is filled with gas and whose elasticity is increased while the gas is exhausted, and a steering column part connected to the steering wheel for decreasing a secondary shock when the driver strikes the steering wheel at the time of a collision of the vehicle while slidably moving lengthwise by the gas pressure varying depending on the control of a controller. The steering column part has a plurality of hollow steering columns. The compressed gas is supplied to the inside of the steering column part and exhausted therefrom by the control of the controller. If the collision of the vehicle is detected, since the steering column is collapsible lengthwise, the distance between the driver and the steering wheel becomes long. The elasticity of the steering wheel from which the internal gas is exhausted, thereby functioning as a kind of an air-cushion for the driver.
