A side airbag, a rear bag portion in which an inflator is provided is inflated and deployed earlier than a front bag portion so the internal pressure in the rear bag portion is higher than that in the front bag portion. Thus, while a shoulder and rear portions of a chest and abdomen, which have a relatively high load tolerance, are restrained by the rear bag portion early, the front portions of the chest and abdomen, which have a relatively low load tolerance, are softly restrained by the front bag portion. In addition, a waist having load tolerance higher than that of the shoulder, the chest, and the abdomen of the seated occupant is restrained by a lower bag portion. When the internal pressure in the lower bag portion is increased, gas from the lower bag portion to the rear bag portion is restricted by a check valve.
