[Structure] A test specimen 6 is formed so as to be rotatable about a shaft that supports the base, and is detachably held by a test specimen holding claw 4 provided at the tip of the impact arm 2. The arm 2 has its base pivotally supported on a support plate attached to a standing wall W, and is connected via a link mechanism 5 to the lower ends of a plurality of coil springs 1 arranged in parallel. The tension arm 3 is rotatably supported by a support device attached to the vertical wall W, and its base is connected to the upper end of the spring 1. The test is carried out by lowering the tension arm 3, swinging up the impact arm 2, and suddenly loosening the tensioned spring 1, causing the test object 6 to collide with the test object 7 on the floor F at high speed.
