Abstract:
1. An airbag device comprising: a bag body that inflates and deploys as gas is supplied into the bag body and therefore an internal pressure of the bag body rises; a linkage member whose first end portion is bound to the bag body and whose second end portion is provided with an annular latch ring; a retention device that has a retention member capable of penetrating the latch ring, and that retains the second end portion of the linkage member while the latch ring is penetrated by the retention member, and that discontinues retention of the second end portion of the linkage member as the retention member comes out of the latch ring, and that is able to make at least one of a deployed shape of the bag body and the internal pressure of the bag body different, by discontinuing the retention, from a state of the at least one of the deployed shape and the internal pressure brought about while the second end portion of the linkage member is retained; and a support body that supports the retention device, and that has a general surface, wherein the retention member is provided at a position opposite to an occupant-side face of the general surface, and that is provided with a slope surface, and the slope surface slopes and locates on a face opposite to an occupant-side face of the retention member, that slopes so that a distance between the slope surface and the general surface is shorter at a distal end of the retention member than at a site relatively near to the base end of the retention member.
