Claims

[Scope of Claim for Utility Model Registration] (1) In a microhardness tester equipped with an indenter and a loading device that applies a test load to the indenter, a lever is supported so as to be able to rotate up and down by a fulcrum provided on the machine body. Attach a holder to hold the indenter to the tip of the
The load of the loading device is applied to the holder from above through a vertically movable load transmission shaft, and the level of the force application point, which is the contact position between the load transmission shaft and the indenter holder, is set to the level of the fulcrum of the lever. A microhardness meter characterized by being located nearby. (2) The lower part of the load transmission shaft branches into a pair of columns that pass through both sides of the holder, and the lower ends of the columns abut against a pair of horizontal arms protruding from the bottom of the indenter holder. A microhardness meter according to claim 1 of the utility model registration claim.
