Abstract
An inflator is formed of a cylindrical casing, and a partition situated in the casing to be offset from a middle in a longitudinal direction of the casing to one end side of the casing. Thus, the casing has a first chamber on the one end side and a second chamber on the other end side. A gas generant is filled in the first and second chambers for generating gases. First holes are formed in the casing only near the partition to communicate with the first chamber. When the gas generant in the first chamber is ignited, a gas is ejected through the first holes near the partition to inflate the airbag as equal as possible in the longitudinal direction. Second holes are formed in the casing only at the middle in the longitudinal direction of the casing to communicate with the second chamber. When the gas generant in the second chamber is ignited, a gas is ejected through the second holes at the middle of the casing to equally inflate the airbag in the longitudinal direction.
