form. The boss 41 has a female screw hole 10 formed at the upper end of the drive shaft 9 protruding into the ice cutting case.
A male screw 43 to be screwed into is buried so as to protrude downward. A cylindrical hopper 45 that is slightly narrowed at the top is attached to the annular connecting piece 44.

The cover is shaped to cover the upper part of the ice shaving case and hopper 45, and is provided with a locking piece 51 which hooks onto the aforementioned hook 25 from below, and a key-shaped piece 52 which hooks onto the key 27 of lock piece 26. On the top surface, there is provided an opening 53 which matches the upper opening of hopper 45, and a lid plate 54 which is pivotally supported on one side by opening 53 and can be opened and closed freely.

(Function) The assembly procedure of the present invention is as shown in FIG. After placing the ice-shaving case on the frame along the inclined surface 15 of No. 14, the ice-shaving case is rotated counterclockwise while lightly pressing the case (FIG. 5). Then, the engagement piece 32 on the inner periphery of the skirt portion 30 is moved to the locking piece 3 of the mounting seat 11.
1, and the lower left end of the side wall 21 abuts the left non-inclined surface of the ruler plate 14, thereby fixing the two. In order to incorporate the rotary blade into the ice-shaving case, a drive shaft 9 protruding into the case is used.
A screw 43 embedded in the boss 41 of the wing is screwed into the screw hole 10 at the upper end. Ruler plate 14 is unique to the present invention.

Next, to put the cover on the ice shaver case,
