Abstract: A side airbag device includes: an inflator; a cushion that is expandable from the side of a seat toward a front of a vehicle; a vent hole that is provided at a predetermined position of the cushion and that discharges the gas; a patch that openably covers the vent hole from an inside of the cushion; a tether that is connected to the patch and a predetermined position (a tether cutter) of the side of the seat, the tether pulling the patch toward a rear of the vehicle so as to open the vent hole when the cushion is expanded and deployed; and a tether cutter that is configured to cut the tether in response to information relating to a state of the vehicle.
