In the snow-blower, preferably, the handles ( 11, 12 ) provided on the frame ( 10 ) include upper and lower handle sections. In the snow-blower of this invention, preferably, a snow-throwing device ( 50 ) is fixed on an auger cover, and provided on a tilt-adjusting stand which can be tilted with respect to the frame by means of a link mechanism.
