Description of the Related Art Conventionally, as a fatigue test method for a golf shaft, there are a bending tester which repeatedly applies an external force only in the bending direction to an object to be tested and a torsion tester which repeatedly applies an external force only to the object to be tested in a torsional direction. Used alone, each test was conducted separately. However, when a golf club is actually used, the load in the bending direction and the load in the twisting direction act on the golf shaft at the same time. For example, the bending test and the twisting test are performed independently to evaluate the durability of the golf shaft. Was not enough. Therefore, conventionally, a test for applying a composite load similar to the actual load to the golf shaft has also been performed by using a trial hitting robot or the like.
