A split-opening portion is formed by two transverse breakable portions that extend substantially along the transverse direction of a vehicle, two front-rear breakable portions that extend substantially along the front-rear direction of the vehicle and are connected to the transverse breakable portions, and a middle breakable portion that is located between the two transverse breakable portions and extends substantially along the transverse direction of the vehicle. The middle breakable portion is connected to the front-rear breakable portions. In a front passenger seat airbag apparatus, the split-opening portion is broken by pressing force of an inflated airbag so that door portions are separated from the door adjacent portion, and the door support portions are pivoted together with the door portions about hinge portions serving as fulcrums. The breaking strengths of parts of the split-opening portion are varied such that is broken in the order of the transverse breakable portions, the front-rear breakable portions, and the middle breakable portion. |
