PROBLEM TO BE SOLVED: To provide an endurance performance testing apparatus performing both an endurance test and a performance test of a mechanical component, or the like. SOLUTION: The durability performance testing apparatus includes: a movable part (spindle 30) moved relative to a trestle 9; a movable jig 50 connecting a test piece 2 to the movable part (spindle 30); resistance force measurement means (component force sensor 51, torque sensor 52) measuring the resistance force of the movable part (spindle 30) and the test piece 2; a locking member 53, regulating relative displacement between the movable jig 50 and the movable part (spindle 30); and a lock-switching mechanism 55 for switching and holding the lock member 53 between a regulation position in which the relative displacement between the movable jig 50 and the movable part (spindle 30) is regulated and a release position, in which the relative displacement between the movable jig 50 and the movable part (spindle 30) is not regulated.
