Abstract: At the time of a frontal collision of a vehicle, even in a case in which knee regions of an occupant are in a state of being close to a housing of a knee airbag, the knee regions can be appropriately restrained with the knee airbag. When knee airbag 14 receives a supply of gas and expands and deploys towards the occupant side in the front passenger seat, expansion and deployment of a central region 14A of knee airbag 14 is suppressed by a flap 16 (a deployment control cloth), and end portion regions 14B expand and deploy before central portion 14A. Since these end portion regions 14B respectively expand and deploy from between the knee regions of an occupant and glove box door 24 towards the outer sides of the knee regions, a reaction force of knee airbag 14 with respect to the knee regions can be weakened.
