Claim:
1. An airbag device for a front passenger seat adapted to be mounted on an instrument panel disposed in front of the front passenger seat of a vehicle, the airbag device comprising a housing adapted to be disposed on a top plane of the instrument panel and an airbag which is housed in the housing in a folded-up configuration and inflatable with an inflation gas, the airbag comprising: a passenger-side wall deployable generally vertically at a rear region of the airbag in such a manner as to face the front passenger seat; a circumferential wall configured to extend forward from a peripheral edge of the passenger-side wall in a tapering fashion, the circumferential wall including a lower wall that is deployable on a lower region of the circumferential wall; a gas inlet port disposed generally at a center in a left and right direction in a vicinity of a front end of the airbag as deployed for taking in the inflation gas; a bottom pocket that is recessed upward from the lower wall of the circumferential wall in a pouch in such a manner as to be continuous with the lower wall and have an opening at a lower end of the bottom pocket on the lower wall, the bottom pocket being formed by joining outer circumferential edges of a pair of bottom pocket constituent regions that extend from the lower wall at left and right peripheries of the opening of the bottom pocket; and a tether that is disposed generally along a front and rear direction inside the airbag, the tether connecting the passenger-side wall and a vicinity of the gas inlet port for preventing the passenger-side wall from protruding rearward at airbag deployment, the tether being connected to an upper end region, i.e., a bottom region, of the bottom pocket, wherein: the lower wall of the airbag is composed of a pair of lower panel sections each of which is configured to form a left or right half region of the lower wall; and each of the bottom pocket constituent regions extends from each of the lower panel sections, each of the bottom pocket constituent regions is formed to protrude partially from the lower panel sections; the bottom pocket is formed into a pocket by joining together the outer circumferential edges of the pocket constituent regions with a first joint section, and the first joint section is continuous with a second joint section that joins the edges of the lower panel sections.
