According to the airbag device of the fourth aspect of the present invention, the sewn portion of the reinforcing cloth of the exhaust hole extending toward the gas inlet side of the airbag body is formed on the outer peripheral side of the reinforcing cloth of the exhaust hole. Since it is formed in a parabolic shape with the vertex at the top, it can be sewn continuously with the circular sewing, and the sewing work can be performed easily,
It is possible to more effectively prevent the outer peripheral edge of the reinforcing cloth in the exhaust hole from being turned up by the gas pressure from the gas generator, and to prevent the exhaust from the exhaust hole from being hindered.

According to the present invention, the outer edge of the reinforcing cloth sewn to the outer edge of the exhaust hole of the airbag body of the airbag device is prevented from being turned up by the gas pressure from the gas generator, and the exhaust hole is prevented. Can be prevented from being obstructed, and even if the folded state of the airbag body is maintained for a long time and the outer peripheral edge of the reinforcing cloth in the exhaust hole of the airbag body is bent, the exhaust air is exhausted. It is possible to obtain an economical airbag device that can prevent the exhaust from the hole from being hindered.
