To provide a curtain airbag device for a vehicle, capable of inhibiting the head of an occupant from moving outward in a vehicle width direction while suppressing an increase in manufacturing cost.SOLUTION: A curtain airbag device 40 for a vehicle includes: a curtain airbag 50 having a sub chamber 52 the lower end part of which, by the supply of gas through a main chamber 54 for protecting the head PfH of an occupant Pf at least in the event of rollover of a vehicle 10, is inflated and deployed to a vehicle lower side relative to a door belt line BL along side glass 16; and an extension cloth 80 which is provided at the lower end part of the sub chamber 52 so as to extend to a vehicle lower side relative to the lower end part of the sub chamber 52, and in which the friction coefficient of an outer face capable of coming into contact with a door trim 77 is made greater than the friction coefficient of a base cloth forming the curtain airbag 50.SELECTED DRAWING: Figure 1

    【課題】製造コストの増加を抑制しつつ、乗員の頭部の車幅方向外側への移動を抑制できる車両用カーテンエアバッグ装置を得る。【解決手段】少なくとも車両10の横転時に、乗員Pfの頭部PfHを保護する主チャンバ54を経てガスが供給されることにより、下端部がサイドガラス16に沿ってドアベルトラインBLよりも車両下方側へ膨張展開する副チャンバ52を有するカーテンエアバッグ50と、副チャンバ52の下端部よりも車両下方側へ延在するように、副チャンバ52の下端部に設けられ、ドアトリム77と接触可能な外面の摩擦係数が、カーテンエアバッグ50を構成する基布の摩擦係数よりも大きくされた延長布80と、を備えた車両用カーテンエアバッグ装置40とする。【選択図】図1
