Claim Text:
1. A vehicle side-airbag device comprising: an inflator that is provided at a vehicle seat and is operated to generate gas in cases in which a side face collision of the vehicle is detected or predicted; a side-airbag that is provided at a side portion of a seatback of the vehicle seat, that inflates and deploys between a seated occupant and a vehicle body side portion due to gas generated by the inflator being supplied inside the side-airbag, and that is partitioned in an inflated and deployed state, into a shoulder bag section extending from a side of a shoulder of the seated occupant toward a vehicle front and a main bag section positioned at a side of a chest and abdomen of the seated occupant, the main bag section being further partitioned into a front bag section and a rear bag section aligned in a row along a vehicle front-rear direction; and an inner tube provided at the side-airbag so as to be positioned at a vehicle rear side of the rear bag section in the inflated and deployed state, with the inflator provided inside the inner tube that is in communication with the shoulder bag section interior and the rear bag section interior, wherein a vehicle width direction dimension of the shoulder bag section is set smaller than that of the main bag section in the inflated and deployed state, such that a vehicle width direction inner side face at an upper end side of the main bag section forms an upper arm-push-up face that is sloped or curved so as to rise on progression toward a vehicle width direction outer side.
