Tensile strength tester

摘要

A tensile strength tester feasible of the present invention is feasible for automation and includes a rotating member and a pulling member connected to each other. A torque is transferred from the rotating member to the pulling member with a counterforce being absorbed at the position where the two members are connected. Such a connecting portion is prevented from becoming loose. The tester is capable of measuring a tensile strength when a screw member fitted in a base material is pulled out of the base material.
