PROBLEM TO BE SOLVED: To constitute a flanger without being divided, by always positioning the flanger in a specific place. SOLUTION: In left sled snowplowing, a left support blade rotates so that the flanger for a front left support blade is positioned on the center line in the longitudinal direction of a snowplow, and a right support blade is positioned in parallel to the center line. In V snowplowing, the left support blade rotates so that the flanger is positioned on the center line in the longitudinal direction of the snowplow, and a left tip blade rotates to the advancing directional side, and the right support blade rotates a little to the left tip blade side. In right sled snowplowing, the right support blade rotates so that the flanger is positioned on the center line in the longitudinal direction of the snowplow, and the left support blade is positioned in parallel to the center line. The flanger is lowered when positioned on the center line in the longitudinal direction of the snowplow in the left sled snowplowing, the V snowplowing and the right sled snowplowing, and is raised in the other case.
