Abstract
A fatigue testing device 1 comprises a fixing member 4 constituted by a lower jig 2 and an upper jig 3. The lower jig 2 and the upper jig 3 are fixed with a bolt 5, and a sheet or plate-shaped metal plate 6 is fixed in a cantilever state such that it is interposed between the lower jig 2 and the upper jig 3. The lower jig 2 has a fixing surface 2a to which the metal sheet or plate 6 is fixed, and the fixing surface 2a has a curved shape such that the space between the fixing surface 2a and the metal sheet or plate 6 increases with increasing distance from the location where the metal sheet or plate 6 is fixed to the fixing surface 2a. The upper jig 3 also has a fixing surface 3a to which the metal sheet or plate 6 is fixed, and the fixing surface 3a has a curved shape such that the space between the fixing surface 3a and the metal sheet or plate 6 increases with increasing distance from the location where the metal sheet or plate 6 is fixed to the fixing surface 3a.
