Abstract
A fatigue testing devicecomprises a fixing memberconstituted by a lower jigand an upper jig. The lower jigand the upper jigare fixed with a bolt, and a sheet or plate-shaped metal plateis fixed in a cantilever state such that it is interposed between the lower jigand the upper jig. The lower jighas a fixing surfaceto which the metal sheet or plateis fixed, and the fixing surfacehas a curved shape such that the space between the fixing surfaceand the metal sheet or plateincreases with increasing distance from the location where the metal sheet or plateis fixed to the fixing surface. The upper jigalso has a fixing surfaceto which the metal sheet or plateis fixed, and the fixing surfacehas a curved shape such that the space between the fixing surfaceand the metal sheet or plateincreases with increasing distance from the location where the metal sheet or plateis fixed to the fixing surface
