ABSTRACT:
A retarding device of a grinding machine comprises a casing and a grinding element, wherein the casing is securely installed with a circular flat plate around the periphery of the output shaft installed thereon. A fixing seat is installed on the rear side of the grinding element, and a fixing seat is installed with a plurality of friction elements so that the grinding element is combined with the output shaft, and thus the friction element contacts with the flat plate. Therefore, as the grinding element is rotating, the rotary speed of the grinding element is retarded by the friction forces between the friction elements and the flat plate.
