An air bag apparatus for a vehicle seat, comprising:

• a side bracket disposed in an outer portion of a seat back in a widthwise direction of the vehicle and secured to a seat back frame;
• and
• an air bag module attached to the side bracket, wherein
• the seat back has a side pad portion in the outer portion in the widthwise direction of the vehicle,
• the air bag module has an inflator for generating gas and an air bag body arranged to be unfolded forwardly by gas generated by the inflator,
• the air bag module is structured to allow deformation of the side pad portion when depressed by a person on the seat,
• the side bracket has a side panel disposed rearwardly of the side pad portion and extending in a lengthwise direction of the vehicle and a rear panel disposed inwardly of the side panel in the widthwise direction of the vehicle and structured to extend in the width direction of the vehicle, and
• the inflator is disposed adjacent to the rear panel of the side bracket.
