Airbag device

An airbag device mounted on a vehicle, the airbag device comprising:

• an airbag configured to be folded and accommodated, be inflated by being supplied with an inflation gas, and receive an occupant of the vehicle;
• an inflator that discharges the inflation gas to be supplied to the airbag;
• a coupling member having one end portion coupled to the airbag;
• an actuator that controls an inflated state of the airbag by switching between holding and releasing of the holding of the other end portion of the coupling member, the actuator including:
• a squib;
• a cap that is disposed to face the squib and holds the other end portion of the coupling member;
• and a housing that maintains, by locking the cap, a state where the cap holds the other end portion, in which the locking of the cap by the housing is released by gas generated by operation of the squib, and the holding of the other end portion by the cap is released;
• and
• a bracket that holds the actuator and fixes the actuator to the vehicle including the airbag device,
• wherein
• the bracket includes a support portion that is in contact with an intermediate portion between the one end portion and the other end portion of the coupling member and supports the coupling member while bending the coupling member in a state where the squib does not operate,
• the airbag device includes a case that houses the airbag in a folded state and to which the bracket is fixed, and
• the case includes a belt support portion that is in contact with the intermediate portion of the coupling member and supports the coupling member while bending the coupling member.
