2. Description of the Related Art As a simple ice shaving device for general household use, for example, Japanese Utility Model Publication No. 1-180283 and Japanese Utility Model Publication No. 2-200.
The one disclosed in Japanese Patent Publication No. 69 etc. is known. These ice shaving machines form a slit facing the cutting blade on the bottom of the dish-shaped shaving machine body fixed on a support stand, and a spiral-type presser foot that is rotatably mounted inside the shaving machine body. A bottom is formed, and an ice block introduction port is provided between the high end and the low end of the holding bottom.

In the above-described gear mechanism for ice shaving of an ice shaving device, a drive gear having a handle attached thereto is arranged in a vertical plane, and an annular driven gear meshing with the drive gear is fitted horizontally around the hopper. The structure is such that they are locked together.

When the drive gear is rotated by operating the above handle, the driven gear and the hopper rotate integrally, and the ice block in the hopper is introduced from the ice block introduction port to the lower surface of the spiral pressing bottom. The introduced ice block is cut in contact with the cutting blade and falls downward from the slit.

[0005]

In the hopper described above, a cylindrical boss portion provided at the center of the hopper is rotatably fitted to a fixed shaft provided at the center of the bottom of the scraper main body, and the boss of the fixed shaft is removed. The collar of the cap screw screwed on the upper end is engaged with the upper end surface of the boss portion to prevent the hopper from coming off. For this reason, when a reaction force during cutting of ice blocks acts on the hopper, the hopper may float from the bottom surface of the scraper main body due to the fitting clearance and the bending of the material. When the hopper floats, the contact between the ice and the cutting blade becomes unstable, resulting in a decrease in the cutting amount.

[0006] Therefore, an object of the present invention is to prevent the hopper from floating during cutting and to make sure that the cutting blade is brought into contact with ice.
