To provide a vehicular airbag whose expansion speed can be stably controlled during inflation and expansion thereof.SOLUTION: A vehicular airbag has a base cloth 15 for tether. The base cloth 15 for tether has stitches 155, 156 which extend with one side on X direction right side as an initial point, and are apart from each other. A tip 153a of a cut off part 153, which is sandwiched between a stem 150 and a stem 151 in a Y direction, is joined to a steering side air bag panel which constitutes a bag body. Each tip 150a, 151a of the stems 150, 151 is joined to a crewman side air bag panel which constitutes a bag body. When a tensile force F, F' is added between the tip 153a and the tips 150a, 151a during inflation and expansion of the bag body in the vehicular airbag, the stitches 155, 156 are sequentially cut, whereby the tip 153a and the tips 150a, 151a are separated from each other, and a tether length of the base cloth 15 for tether is extended.SELECTED DRAWING: Figure 4

    【課題】膨張展開時において展開速度の安定したコントロールが可能な車両用エアバッグを提供する。【解決手段】車両用エアバッグは、テザー用基布15を有する。テザー用基布15は、X方向右側の一辺を起点として伸び、互いに離間するステッチ155,156を有する。Y方向において、基部150と基部151との間に挟まれた切剥がし部153の先端部153aは、袋体を構成するステアリング側エアバッグパネルに接合されている。そして、基部150,151の各先端部150a,151aは、袋体を構成する乗員側エアバッグパネルに接合されている。車両用エアバッグにおける袋体の膨張展開時には、先端部153aと先端部150a,151aとの間に引張力F,F‘が加わると、ステッチ155,156が順次切断されてゆくことにより、先端部153aと先端部150a,151aとが互いに離間し、テザー用基布15のテザー長が伸長する。【選択図】図4
