the airbag cushion includes an expansion and deployment part that is expanded and deployed by the gas from the inflator, and an exhaust vent part that protrudes from the peripheral edge of the airbag cushion; and
the expanded and deployed airbag cushion is configured such that when a load acts on the expansion and deployment part, the exhaust vent part opens to allow the inside of the expanded and deployed portion to communicate to the outside.
