A gas generator, especially for an airbag of a vehicle having a cylindrical outer tube, open end faces of which are closed by cover elements, comprising an inner tube of smaller diameter which is arranged coaxially inside the outer tube and which has outflow openings, an ignitable gas-generating material inside the inner tube, filter elements in an annular space arranged between the inner tube and the outer tube, and an igniter unit for igniting the gas-generating material. In order to improve the damming and sealing of the outflow openings, there is arranged in the inner tube a rolled-up, self overlapping damming strip adjoining the wall at least partially. Also, the outflow openings are covered on the outside of the inner tube by a sealing strip having at least two mutually overlapping portions of differing widths.
