PURPOSE: To evenly press down a grader blade on a snow face and increase the snow-clearing work efficiency, by detecting the lateral acceleration at the time of turning travel by an acceleration sensor and stretching a hydraulic cylinder inside the turning direction, on clearing away snow.

CONSTITUTION: A hydraulic cylinder 50 is arranged at both right and left sides of the center line in the front and rear direction of a car body and connected to a grader blade 30 which is moved up and down against a snow face by the extension and contraction of respective hydraulic cylinders. When the vehicle 10 turns, the generated lateral acceleration is detected by an acceleration sensor 76 and the output signal is transmitted to a controller 70. The controller 70 actuates a hydraulic control valve 78 to stretch the hydraulic cylinder 50 at the turning side and press down the turning direction side of the blade 30. In this way, snow can be removed efficiently even when turning to the right or to the left in a mountain path with many curved roads or at a crossing and a low cost snow-clearing vehicle 10 with a simple structure can be obtained.
