Abstract
An airbag device includes an airbag, a blocking member that can adjust an exhaust hole of the airbag to a blocked state and an opened state, a coupling member, and a holding and releasing unit, which maintains a state of blocking the exhaust hole by holding the coupling member. When the holding and releasing unit releases the holding of the coupling member, the blocking member inverts in such a way as to be fed out from an inner peripheral face side of the airbag to an outer peripheral face side through the exhaust hole owing to being pressed by inflating gas, and causes inflating gas to be discharged from a through hole formed between leading end regions of outer peripheral edges of a first panel portion and a second panel portion in the blocking member and a communication hole communicating with the exhaust hole.
