A multi-stage gas generator with which a plurality of sites (chest, waist, knees, etc.) on the body of a passenger can be protected together using a single gas generator is provided. A first gas discharge port 21 is connected to a chest-protecting air bag, a second gas discharge port 22 is connected to a waist-protecting air bag, and a third gas discharge port 23 is connected to a knee-protecting air bag. Gas generated in a first gas generating chamber 13 and a second gas generating chamber 14 is discharged from each discharging port to inflate and deploy the air bags for chest, waist and knee, and thus the body of the passenger is protected.
