The invention provides an airbag device for a vehicle, an airbag device for a saddle-type vehicle, and an airbag device for a standing-type vehicle. An airbag can be separated from a locked state with a simple structure. An airbag device for a vehicle is provided with an inflator (41) and an airbag (42), and in the airbag device for the vehicle in which the airbag (42) is separated after inflation, a guide part (60) for guiding gas is provided within the airbag (42), the airbag (42) is connected to the inflator (41) via the guide part (60), the airbag (42) has a gas inlet part (53), and the guide part (60) has an inflation part (60b) inserted into the inlet part (53) and disposed inside the airbag (42). The gas of the inflator (41) flows into the airbag (42) through an expansion part (60b), and the expansion part (60b) expands to be larger than the diameter of the inlet part (53) when the pressure is equal to or greater than a predetermined gas discharge pressure, and can deform to be smaller than the diameter of the inlet part (53) when the pressure is smaller than the predetermined gas discharge pressure.
本发明提供车辆的气囊装置、鞍乘型车辆的气囊装置及立乘型车辆的气囊装置,以简单的构造使气囊成为能够与卡止状态切离的状态。车辆的气囊装置具有充气机(41)和气囊(42),在气囊(42)在膨胀后切离的车辆的气囊装置中,在气囊(42)内设置有对气体进行引导的引导部(60),气囊(42)经由引导部(60)而与充气机(41)连接,气囊(42)具有气体的入口部(53),引导部(60)具有插入至入口部(53)且配置于气囊(42)的内侧的膨胀部(60b),充气机(41)的气体通过膨胀部(60b)而流入到气囊(42)内,膨胀部(60b)在规定的气体喷出压力以上时膨胀为比入口部(53)的直径大,在小于规定的气体喷出压力时能够变形为比入口部(53)的直径小。
