An object of the present invention is to provide a side airbag device capable of quickly and appropriately restraining occupants in the initial stage of airbag deployment, and a occupant protection device having the same. The airbag employed in the present invention includes a first chamber (C1) accommodating the inflator and deployed from the outside in the vehicle width direction of the frame side wall portion, and a second chamber (C2) deployed inside the frame side wall portion in the vehicle width direction, , a gas guide 100 arranged to surround the inflator in the first chamber. In addition, the first chamber C1 is developed such that at least a part thereof overlaps the frame-side wall portion when viewed from the vehicle side. A first inner vent is formed at a boundary portion between the gas guide and the first chamber, and gas is introduced into the first chamber from the gas guide through the first inner vent. In addition, a second inner vent is formed at a boundary portion between the gas guide and the second chamber, and gas is introduced into the second chamber from the gas guide through the second inner vent. |
