A snowmobile comprises a vehicle body, a suspension mechanism connected at a lower portion of the vehicle body and a torsion mechanism for preventing the outward inclination of the vehicle body when the snowmobile is turned. The tension mechanism is provided with a U-shaped tension member which consists of a pair of arms and a base. The arms extend lengthwise of the vehicle body and have their free ends connected to the rear portion of the suspension mechanism. The base has its both ends secured to the other ends of the arms and is made of material of high torsional rigidity and rotatably supported by the vehicle body. When the snowmobile is turned quickly, the torsion mechanism acts to substantially equalize the downward flexture of both lateral side portions of the suspension mechanism, thereby to prevent the vehicle body from being excessively inclined outward of its turning under a centrifugal force exerted thereon.
