PROBLEM TO BE SOLVED: To provide a practical blowing-away snow fence for making aspect good, by performing prevention of a snowdrift and relief of visibility obstacle in a normal wind time, preventing generation of the snowdrift and preventing a fall of a fence without receiving wind pressure in a normal time and an adverse wind time, and enhancing visibility outside of a road in a fine weather time and a windless time. SOLUTION: This snow fence is provided by arranging a plurality of snow protection plates between both side columns. The respective snow protection plates have a support shaft rotatably received by a support part arranged in the columns in both end parts, and are formed by fixing an adjusting weight to an edge part in the width direction on the side near the road, and are held at a blowing-away angle of inclining downward to the road side in the windless time and the normal wind time, and are supported by the columns so as to be supported on the anti-road side by automatically falling in a substantially horizontal shape in the adverse wind time.
