To provide an air bag device which is excellent in retaining the shape of deployed bags thereof and is capable of appropriately absorbing an impact in a case of a collision with a protection target and restraining the protection target having been knocked up onto a hood from slipping off forward.SOLUTION: An air bag device 20 has a bag unit 22 configured to be deployed on a front part of a vehicle body with a gas supplied from an inflator 21. The bag unit 22 includes a first bag 23, a second bag 24, and a connector, which are annularly connected to one another. The first bag 23 and the second bag 24 are configured to be erected on the vehicle body into a mountain-like shape in such a way to form a substantially triangular shape. The connector is composed of a tether 25 and a third bag 28 where the gas from the inflator 21 flows into.SELECTED DRAWING: Figure 1 【課題】袋体の形状保持性に優れ、保護対象者が衝突したときの衝撃を好適に吸収することができるとともに、ボンネット上に乗り上げた保護対象者が前方にずり下がるのを抑制する。【解決手段】インフレータ２１からのガスによって車体前部の車体上に展開する袋体ユニット２２を備えたエアバッグ装置２０であって、袋体ユニット２２は、環状に連設された第一袋体２３と第二袋体２４と接続体とを備えている。第一袋体２３と第二袋体２４とが車体上に山形状に起立して外形が略三角形状を成す構成とした。接続体は、テザー２５やインフレータ２１からのガスが流れ込む第三袋体２８で構成する。【選択図】図１
