The present invention is to suppress flapping of an air bag at the time when the air bag is expanded and unfolded, and to improve a degree of freedom of an attachment procedure of components to a seatback frame. In a vehicle side air bag device (10), an air bag (20) is fixed to a side frame portion (16A) of a seatback frame (16) via an inflator (28) at a fixed part (20F) set in a rear end of a vertically intermediate part (20M). An upper insertion portion (38) into which an upper end of a reaction plate (26) is inserted is formed on an upper-part (20U) side in a rear end of the air bag (20), and a lower insertion portion (40) into which a lower end of the reaction plate (26) is inserted is formed on a lower-part (20L) side in the rear end of the air bag (20). The reaction plate (26) is modularized with the air bag (20), the inflator (28), and so on, and is fixed to the side frame portion (16A) via the inflator (22). |
