Abstract: A bag holder includes an insertion hole allowing a main body of an inflator to be inserted. A retainer includes a pressing portion that presses a peripheral edge of an inflow opening of an airbag, and an internal thread is provided on an inner peripheral surface side of the pressing portion. The inflator includes an external thread screwable to the internal thread on an outer peripheral surface side, in the main body. The retainer causes, at the time of screwing the internal thread and the external thread to each other, the pressing portion and the flange portion to sandwich a portion of a peripheral edge of the insertion hole in the bag holder, thereby causing the bag holder to hold the airbag and the inflator. The retainer includes a projection extending from the pressing portion and capable of penetrating through the airbag and the bag holder.

Abstract: An airbag device for a front passenger seat includes a front passenger seat airbag main body, a center airbag portion, an actuator and a control section. The actuator is configured to switch a strap between a first state and a second state. In the first state, the center airbag portion is retained in a folded state. In the second state, the other end portion of the strap is released and the center airbag portion is allowed to inflate and expand. The control section sets the actuator to the first state when there is a full overlap frontal collision, and sets the actuator to the second state when there is a collision that is any of an oblique collision against a driver seat side of a vehicle front portion or a small overlap collision.
