An airbag for a front passenger's seat of a vehicle, the airbag comprising: A folded-up bag body adapted to be mounted on an instrument panel located in front of a front passenger's seat for rearward deployment, the bag body being inflatable generally into a square cone whose top is at a front end of the bag body and including: a passenger side-wall deployable at a rear end of the bag body generally vertically and toward the front passenger seat; a circumferential wall extending toward the front end of the bag body from a peripheral edge of the passenger side wall while tapering; a gas inlet port located proximate the front end of the bag body as inflated for introducing an inflation gas; and a recessed area that is sunken forward and extends vertically generally at the center in a left and right direction of the passenger side wall; an upper horizontal tether that is located inside the bag body and connects a left side wall and a right side wall of the circumferential wall which oppose each other in a left and right direction, the upper horizontal tether being deployable generally along a left and right direction in order to limit a clearance between the left side wall and right side wall at airbag deployment; and a lower horizontal tether that is located inside the bag body and connects the left side wall and the right side wall of the circumferential wall, the lower horizontal tether being deployable generally along a left and right direction in order to limit the clearance between the left side wall and right side wall at airbag deployment, wherein the upper and lower horizontal tethers are fabricated of a flexible sheet material and formed generally into a band; the upper horizontal tether is so slanted off a front and rear direction as viewed from a side that a rear end of the upper horizontal tether is located above a front end of the upper horizontal tether at airbag deployment; and the lower horizontal tether is so slanted off a front and rear direction as viewed from the side that a rear end of the lower horizontal tether is located below a front end of the lower horizontal tether at airbag deployment.
