Inside a side airbag, there are provided: a rapid chamber extending from a seat back region over a top region and a bottom region that taper gradually towards the vehicle front; a delay chamber that is positioned between the top region and bottom region, on the vehicle-front side of the seat back region; and a partitioning member that partitions the interior of the side airbag into the delay chamber and the rapid chamber.
