ABSTRACT:
A snowmobile construction comprising a body frame having a slide rail suspended from the body frame through front and rear suspensions, and an endless track which runs under tension upon a drive pulley rotatably borne on the body frame. The driven pulley is rotatably borne on the slide rail, with the slide rail, the front rear suspensions connecting the body frame and the slide rail through link mechanisms, respectively. Compression coil springs and shock absorbers are held between links adapted to shift in directions opposite to each other. As a result, the present invention has the effect that vehicle safety and riding comfortability of the driver is ensured for a changing, wide range of undulations of a snow surface.
