PROBLEM TO BE SOLVED: To provide an air bag for a side air bag device capable of promptly and efficiently performing connecting work to an inflator, by eliminating deviating and turning over of an inner tube in the case of inserting the inflator to a connection cylinder part. SOLUTION: An air bag 41, stored to be folded in an opening peripheral edge in an in-car side, is formed as a constitution inflating a bag-shaped inflation part 43c expanded so as to cover an opening when inflating gas from an inflator of cylinder type flows in, and is provided with a connection cylinder part 50 connecting the bag to the inflator by inserting it. The connection cylinder part 50 is constituted by equipping a cylindrical gas inflow part 43d arranged in an outer peripheral side to communicate with the inflation part 43c and inner tubes 46, 47 arranged in an internal peripheral side of the gas inflow part 43d. The gas inflow part 43d and the inner tubes 46, 47 are connected by forming a mutually fusing fusion part 48. |
