ABSTRACT:
A chain of a driving device for a snowmobile can be adjusted by a simple operation. A gear case is provided with lever portions. One lever portion is mounted on a gear case pivot. The other lever portion is fastened with a bracket provided on an upper frame through a chain adjuster. The chain adjuster has a cam surface and has a rotational shaft held in a slit of the bracket. The chain adjuster is loosened and rotated through a predetermined angle. Then, the gear case rotates around the gear case pivot and the idle shaft moves whereby stretching of the chain can be finely adjusted.
