The present invention provides a vehicle air bag device with which gas leakage prevention can be secured by an operation to mount a bracket on an inflator. The vehicle air bag device includes: an air bag that is formed integrally with an inflator insertion portion 4 into which an inflator 5 for discharging a gas is inserted, and that is inflated and deployed when the gas flows therein from the inflator insertion portion; a bracket that is formed to attach the inflator to a vehicle body side, and that includes an inflator side mounting portion 8 mounted onto an outer side of the inflator insertion portion so as to cover the inflator insertion portion partially; a strip-form body 10 that surrounds and integrates the inflator side mounting portion and the inflator inserted in the inflator insertion portion; and a seal portion 11 that is formed on the inflator side mounting portion in alignment with the strip-form body to seal a gap s formed between the strip-form body and an inflator insertion portion front surface 4b by a step h located between an inflator side mounting portion front surface 8a and the inflator insertion portion front surface.
