PROBLEM TO BE SOLVED: To provide an air belt device capable of varying the amount of fluid supplied to a shoulder part of a bag body and the mount of fluid supplied to a lap part of the bag body.SOLUTION: A tube 56 of an air belt device 19 has a part, where a hole 64 is formed, arranged at a narrow-width part 48 of a bag body 38, and when tension of a cover belt 24 of a cover 22 is increased as a lap pretensioner is placed in operation, discharging of a gas from the hole 64 of the tube 56 is limited, so that much gas flows to a lengthwise tip part of the tube 56. Consequently, a shoulder part of the bag body 38 can be preferentially expanded to spread.SELECTED DRAWING: Figure 8 【課題】袋体のショルダ部への流体の供給量と、袋体のラップ部への流体の供給量とを変更できるエアベルト装置を得る。【解決手段】エアベルト装置１９のチューブ５６において、孔６４が形成された部分は袋体３８の幅狭部４８内に配置され、ラッププリテンショナが作動されてカバー２２のカバーベルト２４の張力が増加されると、チューブ５６の孔６４からのガスの放出が制限され、チューブ５６の長手方向先端部へ多くのガスが流れる。これによって、袋体３８のショルダ部を優先的に膨張展開できる。【選択図】図８
