Abstract

A knee airbag device for a vehicle includes a gas generation portion that is operated to generate gas; a knee airbag that is disposed in a folded state at a predetermined position in a vehicle, wherein when the knee airbag receives the gas, the knee airbag is inflated and deployed toward an area below a steering column so that the knee airbag is disposed between knees of an occupant and a lower portion of an instrument panel; and a thickness regulation member that is provided in the knee airbag at a position in a contact portion that contacts each of the knees of the occupant, and that regulates the thickness of the knee airbag such that the thickness of the knee airbag at the position in the contact portion is smaller than the thickness of the knee airbag in a portion other than the contact portion.
