Abstract
An air bag apparatus is provided which stably projects the air bag towards the front of a passenger. A retainer 12 stores therein an inflator 14 for injecting gas from gas injection holes at one end of the inflator, and an air bag 15 which is folded. A mid-retainer 16 is provided between inflator 14 and air bag 15. Mid-retainer 16 is provided with a plurality of guide fins 61, which are formed by making cuts in the mid-retainer and bending the cut portions. The direction of gas flow is adjusted by the inclination of each guide fin 61. The gas discharge rate is adjusted by setting various distances between each two adjacent guide fins 61 as to be greatest at the central part of the mid-retainer and either side of the center portion having a gas discharge rate approximately equal to its corresponding opposite side, thereby ensuring air bag 15 will be projected stably.
