The rear panel has an opening for the gas generator at the center thereof. An inner panel is provided for dividing an interior of the airbag into a central first chamber and a second chamber around the first chamber. The inner panel has an opening disposed substantially coaxially with the opening of the rear panel. The inner panel has a communication opening at a rear end thereof for communicating the first chamber and the second chamber. When the airbag becomes an inflated state, the communication opening is situated on at extension of a direction that gas is ejected from the gas generator.
