The first gravity center position corresponds to a gravity center of a part, which rotationally moves around the first fulcrum, of the subject and the holder in a case where the subject is held. The bending position corresponds to a bending point of the intermediate part. The second gravity center position corresponds to a gravity center of a part, which rotationally moves around the second fulcrum, of the second fulcrum position and balancer.
