<p>An engine (E) is received vertically in an engine room (36) covered by an engine cover (4), and a generator (62) is arranged in a position above a front end of a crankcase (7) of the engine (E) and facing an opening (101) formed at a front of covers (10, 11). An air flowing from an air intake port (41) formed at a rear, upper portion of the engine cover (4), toward an intake opening (791) of an intake silencer (76) provided at a front, lower end of the engine room (36) cools a generator (62) disposed in a path of flow. A part of air in the engine room (36) is introduced into an interior of belt covers (10, 11) through the opening (101) to be discharged outside from a ventilating opening (751), and at that time the generator (62) is cooled by the air which passes through the opening (101).</p> |
