<p>This invention prevents forceful projecting of an airbag and stops gas discharge outside the airbag in a short period of time. Gas supplied from an inflator (3) causes an inner bag (30) to expand. Gas supplied from flow ports (31-33) causes an outer bag (20) to expand. A discharge tube (40) is disposed so as to reach the exterior of the outer bag (20), the discharge tube discharging gas from a discharge port (41) on a folded section (43). A connecting member (14) connects the folded section (43) to the front surface of the outer bag (20) and retains the folded section (43) and the discharge port (41) inside the discharge tube (40). The connecting member (14) is pulled out from the inner bag (30) as the outer bag (20) expands. The connecting member (14) moves the front surface of the outer bag (20) in the passenger direction (E) and closes the discharge port (41) by pulling in the folded section (43).</p> |
