To provide an air bag device designed to facilitate the configuration of an actuator for adjusting the internal pressure of an air bag.SOLUTION: An air bag device has an actuator 65 operated to release holding of a connection member 60 connected to a closing member, so as to shift the closing member for closing an exhaust hole of the air bag to an opening state. The actuator includes: a body portion 66 provided with a squib 71; and a cap 78 attached to the body portion. The cap includes a fragile portion 86 as movement allowing means 90 that, when a ceiling portion 79 receives pressure of combustion gas F generated when the squib is operated, moves the ceiling portion and also allows a holding portion 88 for holding the connection member to move from a holding position HP of the connection member to a holding release position UP.SELECTED DRAWING: Figure 10
【課題】エアバッグの内圧調整用のアクチュエータを簡便に構成できるエアバッグ装置を提供すること。【解決手段】エアバッグの排気孔を閉塞する閉塞部材を開口状態に移行するように、閉塞部材に連結される連結部材60の保持を解除するように作動されるアクチュエータ65、を有したエアバッグ装置。アクチュエータは、スクイブ71を設けた本体部66と、本体部に取り付けられるキャップ78と、を備える。キャップは、スクイブの作動時に発生する燃焼ガスFの圧力を天井部79が受けた際に、天井部を移動させるとともに、連結部材を保持する保持部88を、連結部材の保持位置HPから保持解除位置UPに移動可能とする移動許容手段90としての脆弱部86を備える。【選択図】図10
