The present invention provides a side air bag apparatus including an air bag unit. The air bag unit contains a side air bag and an inflator in its upper and lower portions, respectively. The air bag unit is attached to an inner panel of a side door through upper attaching portions and lower attaching portions. The air bag unit is configured to move in parallel toward a vehicle occupant compartment during a side impact collision by way of a difference in distance between a side impact input position corresponding to a impact bar and each attaching portion. This enables the side air bag unit to avoid damage during the collision. Further, the side air bag can reliably be expanded between an occupant and the side door. A structure for attaching the air bag unit to the side door can also be simplified.
