A ceiling mounted airbag device has an airbag including a first chamber at a ceiling of a vehicle cabin and configured to rupture the ceiling during a vehicle head-on collision and to be expanded and deployed by a gas at a front side of a passenger seated in a vehicle seat, and the airbag including a second chamber configured to be expanded and deployed toward the passenger by a gas supplied from the first chamber; and a tension member coupling the first chamber with a support section at the ceiling, the tension member rupturing the ceiling and deploying accompanying expansion and deployment of the first chamber, and the tension member relatively pulling the first chamber upward and toward a rear side, in a vehicle front-rear direction, of the first chamber when the passenger, who begins to move toward a front side under inertia, is restrained by the second chamber.
