Abstract

A heat shield for an internal combustion engine exhaust system for supporting a first heat shield plate and a second heat shield plate on a U-shaped exhaust pipe extending from an exhaust port of an engine, via a support member such as band members, and heat shield plate attachment fixtures. The first heat shield plate covers all around a curved section of the U-shaped exhaust pipe in the vicinity of the exhaust port. The second heat shield plate covers an upper part of a straight section of the U-shaped exhaust pipe and extends rearwardly from the curved section. Further, since the exhaust pipe is formed as one piece, the first heat shield plate may be formed as a simple two-part structure using the band members. With this configuration, an effective heat shielding effect can be exhibited, and cost can be reduced.
