PURPOSE:To secure the economic efficiency and safety by increasing the breakage strength of the third broken part that of the first and second broken parts, in an air bag device equipped with a gas generator, air bag body, and a cover member for covering the air bag body, in order to protect a driver in the collision of a vehicle, etc. CONSTITUTION:The operation of a gas generator 4 fixed on a base plate 1 by a fixing means 8 such as bolts and nuts ruptures only the first broken part 21 and the second broken part 23 each of which has a small breakage strength, and a cover member 15 is developed. After an air bag body 3 is buldged out left and right, leaving a strip-shaped part 27, the third breakage part 25 having a large breakage strength is broken, and the strip-shaped part 27 is developed in the longitudinal direction, and the air bag 3 is bulged out. |
