PROBLEM TO BE SOLVED: To improve protectiveness of an air bag unit by disposing the air bag unit near a frame member toward a specified direction, and providing the air bag unit on the seat center side in relation to the frame member. SOLUTION: In an air bag unit 21, an inflator 23 is positioned near the right side of a left side part of a seat back frame 13, and the opening direction of a reaction can 22 is so arranged as to incline to the left in relation to the front. A left outer edge near the opening of the reaction can 22 is positioned more on the seat center side than the left outer edge of the left side part of the seat back frame 13. That is, the left side part of the seat back frame 13 is disposed in such a way as to be extended along the left side part of a seat back 3, and the air bag unit 21 is provided on the seat center side in relation to the left side part of the seat back frame 13. Protectiveness of the air bag unit 21 can thereby be improved. |
