Abstract
The inside of a muffler main body formed from an outer plate into the shape of a cylinder is divided into an upstream-side expansion chamber and downstream-side expansion chambers by partition walls. A catalyst is contained in the upstream-side expansion chamber having a larger volume, and a cylinder-shaped reinforcement member is attached to an inner surface of the outer plate of the upstream-side expansion chamber.
