An airbag includes a bag body and an inlet port section of inflation gas. As a gas receivable region, the bag body includes a front main inflatable region, a rear main inflatable region, a feed path that feeds the inflation gas from the inlet port section to the front and rear main inflatable regions, and a sub inflatable region that absorbs the gas from the front main inflatable region when a pressure of the front main inflatable region soars. A front partitioning region partitions the front main inflatable region from the sub inflatable region. The front partitioning region is disposed in front of a front end of an upper partitioning region in an island-like fashion remote from other uninflatable region so as to provide, at the rear of and there beneath, one each communication passage that provides gas communication between the front main inflatable region and the sub inflatable region.
