Abstract

In an engine including a cooling fan provided at one end of a drive shaft to cool the engine, a muffler is attached such that a longitudinal direction thereof coincide with a direction of gravity, and a muffler accommodating chamber is formed by a muffler cover. A portion of cooling air generated by the cooling fan is introduced into the muffler accommodating chamber so as to cool the muffler. At the muffler accommodating chamber, a cooling air outlet is provided at an upper end of a cooling passage, such that the waste heat of the muffler is discharged from the cooling air outlet to the outside during the stop of the engine. A cooling air inlet is disposed below the cooling air outlet such that the cooling air flows from the lower side to the upper side of the muffler.
