PURPOSE: To make it possible to use the machine even in a freezing season, by arranging layers on which ice is hard to be formed on the peripheral side of the weight measuring table and the surface of a fixed part facing said peripheral side, providing a tapered shape in the gap between said arranged layers, and dropping the ice when some loads are applied on the weight measuring table.

CONSTITUTION: An angle member as the fixing ]art 4 is fixed to the inner surface of a pit 2 formed by digging a hole in the ground 3. The weight measuring table 1 of the weight measuring machine such as truck scale is provided on receiving frames 8 which are fixed to the bottom of the cockpit 2. The layers 5 and 6 comprising the material, on which the ice is hard to be formed, such as polytetrafluoroethylene are bonded to the peripheral side of said weight measuring table 1 and the surface of the fixed part facing said peripheral side by a bonding agent, respectively. The lower part of the gap 7 formed by the facing layers 5 and 6 is expanded so as to form the tapered shape. Therefore, even though the ice is formed on the layers 5 and 6 in the cold season, the ice is slipped and simply separated from the layers 5 and 6 when the loads are applied on the weight measuring table 1 and dropped downward out of the gap 7.
