Claims

[Scope of Claim for Utility Model Registration] (1) A screw shaft and a screw blade rotatably supported within the freezing casing for scraping and guiding the ice frozen on the inner wall surface of the freezing casing, and the screw shaft. A fixed blade that is fitted to the upper end and has an ice compression passage that receives ice from the screw blade, and a cutter that is attached to the upper end of the screw shaft and that breaks the ice from the ice compression passage. In the auger-type ice maker, a positioning part for positioning the cutter at a predetermined position among a plurality of circumferential positions is provided at the upper end of the screw shaft, and the cutter is attached to the positioning part. a cutter blade support part having a mounting part that can change the circumferential position of the cutter in cooperation with the positioning part; An auger-type ice maker comprising a plurality of cutter blades secured around the cutter blade support at correspondingly different pitches. (2) The auger-type ice maker according to claim (1) of the utility model registration, characterized in that a clearance angle is provided at the lower end of the cutter blade to allow ice to escape upward.
