Abstract
A knee airbag device includes a knee airbag that is disposed in a folded state inside a steering column cover. When the knee airbag receives gas, the knee airbag is inflated and deployed from an inside of the steering column cover toward a knee portion of an occupant. The knee airbag includes an interference suppression member that suppresses interference between the knee airbag and a projection body inside the steering column cover, which projects downward toward at least one side in a vehicle-width direction, when the knee airbag is inflated and deployed.
