In this report, the construction and the capacity of a newly designed torsional fatigue testing machine for wire is stated. This testing machine has the following characteristics:
(1) This machine can automatically record the development of torsional deformation.
(2) Mean stress can be given to the wire specimen.
(3) A slender wire can be used as a specimen so that data obtained in this experiment may be applied to the coiled spring.
