Abstract
A gas generator for an air bag has gas discharge ports closed by a seal tape and has two different opening areas. When a pressure inside the gas generator increases due to combustion of a gas generating agent, a gas discharge port having a larger area is first opened to decrease the internal pressure. Subsequently, as the pressure further increases a gas discharging port having a smaller area is opened to decrease the internal pressure.
