Abstract: To effectively retain a deployed airbag without increasing installation man hours, in addition to suppressing rotation of this airbag in a direction away from a seat. For example, a side airbag apparatus 1 installed inside a backrest SB of the seat S includes: an airbag 2; an inflator 3 provided inside the airbag 2; a tether 4; and a bracket 5. The airbag 2 is deployed in a first direction in which a base end side 2a thereof is attached to a seat back frame SBF and the tip side thereof is distant from the backrest SB. The tether 4 includes: one end 4a attached to the seat back frame SBF; and the other end which extends in the first direction on the outer surface of the airbag 2 in the deployed state so as to be attached to the part on the tip side 2b of the airbag 2. A bracket 5 is attached to the seat back frame SBF and provided in the direction in which the tether 4 extends. The tether 4 is supported by the front end of the bracket 5.
