。[Scope of Claim for Utility Model Registration] 1. At the snow inlet of a snow drifting ditch installed in a snowy area, an electric heating wire is installed between the side of the metal cover pedestal and the outer concrete body. A freezing-prevention type snow inlet for a drifting snow groove characterized by being installed inside the lid in close contact with the receiving base to heat the lid receiving base. 2. When the electric heating wire is brought into close contact with the lid holder pedestal, restraining plates made of corrugated steel are attached at several locations along the periphery of the lid holder pedestal to hold down the electric heating wire from the outside. An antifreeze type snow inlet for a snow drifting groove as set forth in claim 1 of the patent registration claim.
