PURPOSE:To prevent a gasbag from slipping off due to its rapid expansion, by coupling the tip end edge of a short connecting rod with a side plate of the gasbag. CONSTITUTION:Base parts 13 and 14 of each of short connecting rods 11 and 12 are pivotally installed free of rotation in both of a projecting edge 8 extending over a top face 7 of a chassis 1 and another projecting edge 9 of a rear body 3 with pivots 15 and 16. Each of tip end edges 17 and 18 of these short connecting rods 11 and 12 is pivotally installed in position where they sould be, with a pivot 19 in which a base part 21 of a short setting rod 20 is pitotally installed, and a tip end edge 22 of the short connecting rod 20 is made to be connected to a side plate 23 of a gasbag 6. As a result, even if the gasbag is suddenly expanded large, the gasbag is prevented from slipping off owing to the short connecting rod and simultaneously these short connecting rods 11 and 12 come open with the rapid expansion of the gasbag centering on the pivot 19, thus no hindrance is brought to their linking. |
