Claim:
A steering column device with a knee airbag device, comprising: a steering column provided with a telescopic mechanism; a column cover that covers a rear end portion of the steering column; an airbag module that is provided inside the column cover, and that includes a gas generation device that is operated to generate gas, and a knee airbag that is inflated and deployed from a folded state by the gas generated by the gas generation device; an airbag door that is provided in the column cover, and that is opened when the airbag door receives an inflation pressure of the knee airbag; a collision prediction device that predicts that a vehicle will have a collision with a collision object; and a control device that operates the telescopic mechanism so that each of the column cover and the airbag module is moved rearward to a predetermined position, when the collision prediction device predicts that the vehicle will have the collision with the collision object, wherein the airbag door includes a side door that is formed in each of side surfaces of the column cover; and when the column cover and the airbag module are moved rearward to the predetermined position, the side door does not substantially interfere with an outline of an instrument panel in a lateral view.
