An exhaust muffler disposed in proximity to a cylinder of a general-purpose engine is provided, in which an exhaust muffler (M) for a general-purpose engine is formed from a muffler main body (15) connected to a cylinder (3) of a general-purpose engine (E) via an exhaust pipe (10) and disposed adjacent to the cylinder (3), a partition member (19) that divides the interior of the muffler main body (15) into a first muffler chamber (16) communicating with the exhaust pipe (10) and a second muffler chamber (17) communicating with an exhaust outlet (35) of the muffler main body (15), and an exhaust cooling pipe (31) exposed outside the muffler main body (15) while providing communication between the first muffler chamber (16) and the second muffler chamber (17). This enables exhaust gas to be cooled effectively by passing though the exhaust cooling pipe (31) when moving from the first muffler chamber (16) to the second muffler chamber (17), thus enhancing the muffling effect due to a reduction in the pressure of the exhaust gas. |
