Abstract
A gas exhaust structure of a battery includes a rupture valve formed in a battery body, and a pipe unit composed by integrating a coupling pipe and an exhaust pipe with each other. A one-side opening of the coupling pipe is coupled to the rupture valve. The exhaust pipe is coupled to an other-side opening of the coupling pipe, guides gas that spouts out from an inside of the battery body through the rupture valve and the one-side opening of the coupling pipe, and exhausts the gas to an outside. The exhaust pipe is arranged to be offset with respect to the rupture valve without allowing an extended line that passes through a center of the rupture valve and a centerline of the exhaust pipe to be perpendicular to each other.
