Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To appropriately control an exhaust valve at low cost by providing an exhaust valve body on the upper wall of the exhaust passage of an engine in a snow vehicle provided with a continuously variable transmission, and interlocking with the exhaust valve body by the variable operation of pulley diameter of the continuously variable transmission via a wire. SOLUTION: When engine speed increases, a movable side half body 7a of a pulley 7 of a continuously variable transmission moves in the arrow mark A direction to approach a fixed side half body 7b. As a result of this, a slide body 13 provided on a support body 9 integrated with the movable side half body 7a slides in the same direction as against a fixed member 17, and a wire 12 is pulled. Consequently, an exhaust valve interlocking with the other end of the wire 12 is opened. When the engine speed is decreased, the movable side half body 7a moves in the direction opposie to that of the arrow mark A, and the exhaust valve is moved in the closing direction. In this way, by interlocking the exhaust valve 1 with operation of the continuously variable transmission, the valve 1 can be made to appropriately open or close according to the engine speed.
