<P>PROBLEM TO BE SOLVED: To provide a load fluctuation mechanism capable of fluctuating a load to be added to an analyte by simple structure and a grindstone coupling degree testing device using the same. <P>SOLUTION: The load fluctuation mechanism includes: a weight support 10 which can be lifted; a plurality of weights 22 to 29 in which movement to the vertical lower direction is restricted, respectively to be supported by the weight support. The weight support 10 drops toward an analyte 101 which is arranged at a lower part of the weights, the weight 22 which is located at the lowermost position directly or indirectly contacts the analyte 101 to add a load of the weight 22 which is located at the lowermost position to the analyte 101, the weight support 10 further drops, the separated weights 22 to 29 contact each other in order from the bottom, and the load to be added to the analyte 101 becomes large. <P>COPYRIGHT: (C)2012,JPO&INPIT |
