A slide rail structure for a snow vehicle includes a main slide rail disposed at the middle of a crawler belt with respect to the width of the crawler belt. A pair of side slide rails are disposed near the opposite side ends, respectively, of the crawler belt. The guide wheels are disposed between the main slide rail and the side slide rails. An appropriate contact load is maintained between the snow vehicle and the snow to thereby enhance the turning ability of the snow vehicle. One or more edges can be provided on a lower surface of the body cover of the snow vehicle. These edges can dig into the snow to compensate for a reduction in the contact force of the affront ski of the snow vehicle with the snow during turning. The front ski of the snow vehicle can be mounted using an elastic, biasing member. This member helps improve timing and responsiveness for turning of the snow vehicle.

A snow vehicle comprising: a slide rail structure; a plurality of pairs of guide wheels supported on the slide rail structure; and a crawler belt supported and guided on a lower surface thereof by said guide wheels; wherein the slide rail structure includes a main slide rail supporting a longitudinal center portion of said crawler belt, and a pair of side slide rails being disposed respectively along opposed longitudinal side portions of said crawler belt, wherein said guide wheels are laterally disposed between said side slide rails, wherein a clearance is provided between said crawler belt and each side slide rail, and wherein said crawler belt selectively engages at least one of said side slide rails when the corresponding clearance is closed between said crawler belt and the at least one side slide rail by deflection of said crawler belt.
