PROBLEM TO BE SOLVED: To judge the right direction at a glance by providing a means for discriminating the right direction for assembling a retainer on an air bag by means of visual observation. SOLUTION: A plurality of bolts 30... are asymmetrically arranged (A1≠B1, A1≠B2) in a retainer 28, and a mask 28b being a sign when installing the retainer 28 is also attached. Plural holes are provided in a port part of an air bag main body in response to positions of the bolts 30..., and a projection is arranged in response to a position of the mask 28. When installing the retainer 28 on the air bag main body, the mark 28b and the projection of the air bag main body are adjusted by means of visual observation, and when the bolts 30 are inserted into the holes, the retainer 28 can be installed in the right direction relative to the air bag main body. That is, whether or not the direction of the retainer 28 to the air bag main body is right can be judged at a glance, so that the retainer can be assembled on the air bag main body without being puzzled about the direction of the retainer 28. |
