Abstract: An exhaust device for an engine, interposed between an engine body, and a supercharger to be driven by a pressure of exhaust gas to be discharged from the engine body, includes a first exhaust passage and a second exhaust passage which introduce exhaust gas to the supercharger; a partition wall disposed between the first exhaust passage and the second exhaust passage, and configured to partition the first exhaust passage and the second exhaust passage from each other; and a valve disposed within the second exhaust passage, and configured to adjust the flow rate of exhaust gas flowing through the second exhaust passage. The partition wall includes a communication portion for communicating between the first exhaust passage and the second exhaust passage.
