PROBLEM TO BE SOLVED: To sufficiently absorb the secondary collision energy to a side wall, of an occupant even when an armrest part is protruded by arranging an inflator on the side surface of a seat back frame with the injection port situated in the front, and forming an opening part on the front end part of the outer side wall of a case body extended to the front side of the seat back frame. SOLUTION: This air bag device is formed of a cylindrical holder 22 for housing an inflator 21, an air bag body 25, and a case body 27 having a cleavable opening part 26. The injection port 23 of the holder 22 is arranged forward. A lid part 30b is integrally formed on the inside wall 30 of the case body 27 through a thin hinge. The air bag body 24 can be swollen only to the front side and fitted between an occupant and the cabin inside wall without being interfered with an armrest part by arresting the inward movement by the side surface 10a of the seat back frame 10, extending the opening part 26 to the front side from the front surface 10b of the seat back frame 10, and extending a reinforcing member 19 from an outside wall 32. |
