Summary:PURPOSE: A measuring device for compression stress relaxation is provided to increase precision of measurement by preventing a measured value from being changed by external environment. CONSTITUTION: A housing(20) forms a space with fixed size in an inside. A test piece(M) is placed inside the housing. A press plate(30) presses the test piece and is equipped inside the housing. A holder(40) makes the press plate press the test piece and is equipped inside the housing. A space block(50) limits the extent in which the press plate presses the test piece and is separately installed in the outer side of the test piece. A load cell(60) measures the stress applied to the test piece and is separately installed with the test piece. A transmission member(70) delivers the stress applied to the test piece to the load cell and is equipped between the load cell and the test piece. An insulating member(80) blocks the thermal transmission and is equipped between the load cell and the housing.
