Abstract
This invention relates to a gas generator for a seat belt retracting power generating device to supply power to an emergency retracting device of a seat belt retractor, and aims to reliably ignite an ignition agent and a driving agent by concentrating flames into a small-diameter passage when a primer is ignited, quickly supplying heat to a gas generating agent chamber, and preventing the ignition agent and driving agent within the gas generating agent chamber from being damped. This invention comprises a cylindrical casing with its one end open, a cylindrical holder chamber disposed at one end of the casing, a gas generating agent chamber which is communicated with the holder chamber via a shoulder formed on the inner wall of the casing and has a diameter smaller than the inner wall of the holder chamber, an ignition agent and a driving agent housed in the gas generating agent chamber, a primer holder which is housed in the holder chamber and has a primer chamber open toward one end of the casing, a caulking part which is formed at one end of the casing to hold the primer holder, a primer held within the primer chamber, and a small-diameter passage which is formed in the primer ho…
