PURPOSE:To enable the heating of handle grips and their vicinities on a snowmobile with an engine forcedly cooled by air, by conducting warm air from the exhaust port of an air shroud through a duct and ejecting the air to the grips of a steering handle. CONSTITUTION:When an exhaust pipe 21e is closed, air warmed by heat exchange with a cylinder 12 in an air shroud 13 is conducted into the side portions 22b of a cover 22 through an air duct 21 and ramified pipes 21c to heat handle grips 14c and their vicinities. The hands on the grips 14c are thus heated without using a special heat source. |
