1. An in-seat airbag device comprising:
an airbag main body having a front-rear chamber that, due to gas jetted from an inflator that operates due to a collision of a vehicle being detected or predicted, expands past one side of a head of a passenger toward a seat front side and is disposed at the one side of the head of the passenger, a left-right chamber that expands from a seat front side end portion of the front-rear chamber toward a seat width direction inner side and is disposed at a seat front side of a face of the passenger, and a distal end chamber that expands from a seat width direction inner side end portion of the left-right chamber toward a seat rear side and is disposed at another side of the head of the passenger,
wherein the airbag main body is structured such that, in a state in which expansion is completed, the left-right chamber has a curved shape as seen in plan view, and
wherein, as seen in plan view, a supporting point at a seat side that supports the airbag main body is positioned on an imaginary straight line that passes through a center of gravity of the head of the passenger and runs along a seat front-rear direction.
