Abstract
PURPOSE:To enable to perform a highly precise measurement of an elongation amount of a test piece, by a method wherein a stylus free-moving elongation gauge and a member for holding a stylus are placed in combination. CONSTITUTION:A test piece 6, which is erected in a tension tester for very low temperature, whose upper side is fastened to a tension retainer rod 2 and whose lower side is secured, is pulled downward to measure the tensile strength of a test piece material. Holding members 22 are attached to the upper and the lower side of the test piece 6 and styluses 26 and 27, engaging the members, are attached to lower parts of double tube bodies 23 which are vertically movably and pivotally attached to the side wall of the tension tester. The styluses 26 and 27 engage the holding members 22A and 22B of the test piece 6, and an elongation measuring part, by which a displacement amount of a distance between the two holding members at the time when the members are caused to follow in a displacement direction is detected (37) as a displacement amount of two tube bodies 24 and 25, is mounted outside the tension tester.
