Abstract

Sound stopping structure for swing unit type internal combustion engine. The object is to provide a soundproofing structure for a rocker unit type internal combustion engine that is less expensive as well as effective in reducing noise without increasing the number of parts. Solution means: In a sound stopping structure for an internal combustion engine 1 of the tilting unit type including an automatic V-belt gear and supported for tilting movement in a vehicle body 2, an air filter 25 it is mounted on an outer periphery of a unit case 20, and an outer side wall 25a of the air filter 25 extends to the outside of the unit case 20 and covers an outer side face of the unit case 20. A soundproofing material 27 is disposed between the portion 25b of the outer side wall 25a of the air filter 25 extending to the outside of the unit case 20 and the outer side face of the unit case 20.
