An airbag is provided to solve problems in an existing airbag which presents a high risk of injury to a human body caused by a collision of the human body against a tightly expanded airbag after the expansion of the existing airbag. The airbag according to the present device enables air to easily flow through innumerable minute holes which are present in the existing airbag material itself, and has another airbag which surrounds the existing airbag once more, wherein the top surface of the airbag which the human body bumps into has inner and outer airbags attached to each other and the lateral surface of the outer airbag has a corrugated shape and is separated from the lateral surface of the inner airbag. Thereby, expansion gas in the airbag inflates only the inner airbag in motor vehicle crashes. In case that the human body collides with the airbag, the gas filled in the inner airbag is easily exhausted and the airbag can absorb the impact of the human body. After the exhausted gas fills up a corrugated space formed between the inner airbag and the outer airbag, the gas is not allowed to escape easily, and thus the shape of the airbag is maintained and the human body is prevented from directly colliding against a steering wheel or a dashboard of a motor vehicle.
