ABSTRACT:
An object of the present invention is to provide a fall impact apparatus, namely a fall impact apparatus, which is capable of fixing the attitudinal angle of a test subject during a drop test until the moment at which the test subject collides with a dropping subject surface.The fall impact apparatus includes a test subject fixing member for fixing a test subject which is to be tested for impact strength at a desired attitudinal angle, a hoisting and dropping member for raising and dropping the test subject fixing member to which the test subject is fixed along the falling direction of the test subject, and a dropping subject surface structured so as to collide only with the test subject at the terminal end of the falling direction without interfering with the hoisting and dropping member when the hoisting and dropping member is dropped together with the test subject fixing member. The test subject fixing member is supported by the hoisting and dropping member without being affixed thereto such that when the test subject collides with the dropping subject surface, the fixing member separates freely from the hoisting and dropping member.
