PROBLEM TO BE SOLVED: To use gravity for providing torque in a technology of using a rotary body possessing a rotary shaft. SOLUTION: Horizontally fixed two rotary shafts 2 are connected by inversely rotating two gears. Eight rotary bodies 4 possessing a slidable gravity center moving body 5 are rotated in the clockwise direction by being fixed at an equal interval to one rotary shaft. Eight pulling-up bodies 6 are rotated in the counterclockwise direction by being fixed at an equal interval to the other. The length of the rotary bodies and the pulling-up bodies is set to two times an interval distance of the two rotary shafts. The length of a moving body is set to a half of the length of the rotary bodies. A shape and the number of a pulling-up body contact part of the moving body are adjusted so that moving body pulling-up work is completed in less than 45 degrees of a turning angle after exceeding -22.5 degrees of a vertical lower part of the rotary bodies. The moving body is fixed to the rotary bodies when reaching the uppermost part after completing the pulling-up work. The moving body is slidingly pulled up and moved by releasing a fixation of its position when starting the pulling-up work by rotating the rotary bodies. Torque of the rotary bodies is generated in response to a distance from the rotary shaft of the center of gravity of the moving body. Torque of the whole device provides torque of 30% of weight of one moving body. COPYRIGHT: (C)2007,JPO&INPIT
