PROBLEM TO BE SOLVED: To provide an epoch-making snow dump remarkably easily manufacturable compared with a conventional product by constituting a body frame and an erection frame to be fittingly fixable without being fixed by welding. SOLUTION: This snow dump is constituted by providing the erection frame 2 between the intermediate parts of both free end parts 1A of the body frame 1 presenting approximately U-shape from the top view, and reinforcing the proximal end edge of a bucket 3 by fitting it to the erection frame 2 while fixing the left and right edges of the bucket 3 to both free end parts 1A of the body frame 1 on the tip side from the erection frame 2. The erection frame 2 reinforcing the proximal end edge of the bucket 3 is not fixed by welding to the intermediate parts of both free end parts 1A of the body frame 1 but fittingly fixed to the intermediate parts of both free end parts 1A of the body frame 1.
