Summary:To provide a compact exhaust apparatus for allowing exhaust sounds of each cylinder to be heard. A muffler includes a tubular member the inside of which is divided into three independent expansion paths by partition plates. The partition plates extend in an axial direction. Each of the expansion paths is divided into a first expansion chamber, a second expansion chamber and a third expansion chamber by diametrical partitions. The first expansion chamber and the second expansion chamber are in communication with each other by way of a pipe while the second expansion chamber and the third expansion chamber are communicated with each other by way of a second pipe. A tail pipe is connected to each pipe to discharge exhaust gas to the outside.
