The muffler includes an outer wall defining an internal space of the muffler. A second end portion of the exhaust pipe is located within the internal space of the muffler. A secondary air induction pipe supplies air to the exhaust pipe and is connected to a portion of the exhaust pipe that is within the internal space of the muffler. The secondary air induction pipe extends to the outside of the muffler via a through hole that has an edge, at least a portion of which is defined by each of a first member and a second member of the muffler.
