Abstract
This specification relates to a snowmobile. Each of the right suspension and the left suspension includes a damper capable of expanding and contracting according to the vertical movement of the lower arm and a spring that exerts spring force in the expansion/contraction direction of the damper. The cylinder of the right damper and the cylinder of the left damper are connected to each other through a hydraulic fluid channel so that the hydraulic fluid flows between the cylinder of the right damper and the cylinder of the left damper. This snowmobile can reduce the difference in contact pressure on snow surface between the left ski and the right ski, when the vehicle turns.
