Title: Retarding mechanism for a grinding machine

Abstract: A retarding mechanism for a grinding machine which is an improvement on a prior patent application, and comprises a body and a grinding member. Wherein, the body is fixedly provided with an annular plane plate encircling an output axle thereof, the grinding member is fixedly provided with a fixing seat on the rear surface thereof, the retarding mechanism is characterized by that: the fixing seat is provided with a plurality of peripheral abrasive members which are arciform raised portions to render the abrasive members more solid and resistive to grinding and contactable with the plane plate in larger area. Therefore, during rotation of the grinding member, the abrasive members can provide a better structure to get larger friction force with the plane plate to endue the grinding member with a desired retarding effect.
