Abstract: PURPOSE:To easily vary a gap between an ice lump-throwing case and a crushing body, by a method wherein after the ice lump-throwing case is, a little, pulled up above a vessel, the ice lump-throwing case is turned, corresponding to the length of the fit projections thereof, following which the ice lump-throwing case is inserted into the vessel. CONSTITUTION:An ice lump-throwing case 45 can be fitted to a vessel 32 by positioning fit projections 48 therefor between positioning means 55. The ice lump-throwing case 45 can be fitted to the vessel 32 by positioning each of the fit projections 48 between a pair of first projections 56 for each of the positioning means 55. Since both end of the fit projection 48 in longitudinal direction and first projections 56 are closely opposed with each other, these first projections 56 act as a stopper, and the ice lump- throwing case 45 is prevented from turning. First, the ice lump-throwing case 45 is, a little, pulled up above the vessel 32, following which the ice lump-throwing case 45 is turned, corresponding to the length M of the fit projection 48, and finally, the ice lump-throwing case 45 is inserted into the vessel 32. A depth in which the ice lump-throwing case 45 is inserted into the vessel 32, is restricted by the fact that a flange part 46 of the case 45 is placed to a top end opening rim 32a of the vessel 32. For that reason, ice-flakes small in corresponding to this gap 'g' can be made.
