In a front passenger seat airbag apparatus, a partition wall portion is disposed in an airbag to partition the inside of the airbag into a front chamber and a rear chamber. The entire outer circumferential edge of the partition wall portion is jointed with an outer circumferential wall of the airbag, and the partition wall portion includes a communication portion for communication between the front chamber and the rear chamber. The communication portion includes a flow rate control mechanism that controls a flow rate of inflation gas flowing from the front chamber into the rear chamber by increasing or decreasing an opening area of the communication portion. The flow rate control mechanism is configured to suppress flow of the inflation gas into the rear chamber via the communication portion at initial inflation of the airbag in such a manner that the front chamber is inflated, and is configured to open the communication portion in such a manner that the inflation gas flows into the rear chamber by an internal pressure of the front chamber.
