In an air bag device, a folded air bag is accommodated in a condition that the air bag is enclosed by a sheet for preventing the air bag 11 unfolded. The sheet has a regulation wall portion which covers an upper surface of the air bag on the side from which the air bag projects at the time of expansion. The regulation wall portion is provided with a breakable portion which can be ruptured by being pressed by the air bag at the time of expansion of the air bag. Further, the breakable portion is provided so as to be ruptured from one edge side (left edge side) of the circumferential edge sides of the regulation wall portion to the right edge side through the vicinity of the center. |
