A side airbag device for restraining an occupant at an early stage by changing a thickness of a chamber includes a cushion formed in a bag shape by combining an outer panel located at an outer side in a vehicle width direction and an inner panel located at an inner side in the vehicle width direction. A baffle spans between the outer panel and the inner panel in an inside of the cushion and partitions the inside of the cushion into a front chamber located at a vehicle front side and a rear chamber located at a vehicle rear side. An inflator is disposed in the rear chamber, and a first tether and a second tether extend from the baffle toward a vehicle rear. The tethers respectively extend from the baffle via both sides of the inflator in the vehicle width direction so as to be connected with a rear end of the cushion.
