Abstract
There is provided an air bag device in which a bag body can be inflated smoothly in a predetermined form and reduction in cost can be achieved. The air bag device includes an elongated bag body and a wire passes through the bag body along a longitudinal direction of the bag body. The wire is supported movably by a plurality of mounting hardwares. Each mounting hardware passes through slits, which are formed in the bag body and in a cover with the bag body being accommodated therein, to project outward and is fixed at a predetermined position by a bolt. A widthwise dimension of the mounting hardware is made shorter than a longitudinal dimension of each of the slits. For this reason, when the bag body inflates, the bag body suitably moves along the mounting hardwares and tensile force acting in the longitudinal direction of the bag body due to an internal pressure of the bag body at the time of inflation is thereby made uniform. Accordingly, the bag body can smoothly inflate to expand in accordance with a predetermined expanding progress.
