1. An airbag device, comprising:
an airbag that has a peripheral wall;
a connecting member connected to the peripheral wall;
a coupling member whose base portion side is coupled to the connecting member; and
an actuator configured to hold a leading end portion side of the coupling member,
wherein the actuator includes:
a main body portion that is provided a squib on one end side inside; and
a cap, attached to another end side of the main body portion in such a way as to oppose the squib, that includes a ceiling portion, which is provided in such a way as to close off the other end side of the main body portion and is subjected to pressure of a combustion gas emitted when the squib operates, and a fitting protruding portion, which extends to a main body portion side from the ceiling portion, and regulates movement of the cap in a removal direction opposite to an insertion direction by being inserted into a fitting recessed portion provided on the other end side of the main body portion, thereby attaching the cap to the main body portion, and
wherein the fitting protruding portion includes:
a fitting main body portion fitted in the fitting recessed portion of the main body portion;
a holding portion that holds the leading end portion of the coupling member by being inserted into a held portion of the coupling member, the held portion being disposed between the ceiling portion and the other end of the main body portion when fitted to the main body portion; and
a movement permitting unit that, when the ceiling portion is subjected to the pressure of the combustion gas, causes the ceiling portion to move, and causes the holding portion to move from a holding position, wherein the holding portion is inserted into the held portion of the coupling member, to a holding released position, wherein the holding portion is removed from the held portion.
