ABSTRACT:
An airbag of a knee-protecting airbag device is prevented from being damaged during inflation and deployment, and the airbag is allowed to deploy evenly on the left and right sides to improve occupant protection function. The inside of an airbag (10) is defined into a plurality of air chambers (21), (22), and (23) by tethers (24) and (25). An inflator (2) accommodated in a diffuser (30) is disposed in the first air chamber (21). The diffuser (30) is provided with an opening (31) that allows gas from the inflator (2) to flow in the airbag (10) and is disposed so as to face the central portion of the first tether (24). This opening (31) is closed in such a manner that it can be opened by the gas from the inflator (2), and the entirety thereof is simultaneously opened by the gas pressure when the airbag (10) deploys. Thus, the gas in the accommodating portion (32) is supplied from the opening (31) to the airbag (10) evenly on the left and right sides. Furthermore, the diffuser (30) protects the airbag (10) from the gas generated by the inflator (2).
