VEHICULAR AIRBAG DEVICE

Provide an airbag device for a vehicle with a simple structure having improved occupant restraint performance and improved safety. The airbag cushion includes a gas discharge section, a first tether, and a chamber having an occupant side panel and a steering wheel side panel. The first tether includes a first end directly or indirectly connected to the occupant side panel and second ends connected to the steering wheel side panel. The edge of the gas discharge section can be pulled into the chamber by the taut first tether and the area of the gas discharge section opening with the edge of the gas discharge section pulled into the chamber is smaller than when the first tether is relaxed.
