<P>PROBLEM TO BE SOLVED: To provide a gravity rotary driving device rotating rotors utilizing the gravity of a weight and a principle of lever. <P>SOLUTION: The gravity rotary driving device includes a pair of rotors 2A, 2B fixed at a desired interval and provided on a rotary shaft 1; first even number of four or more weight body operation holes formed in a long hole shape and positioned at a nearly equal interval on the outer peripheral part side facing both rotors; first weight bodies having the center part connected by a connection shaft 40, and supported by both rotors movably between one end to the other end of the facing operation holes; second weight body supports provided facing each other rotatably in the set direction making the connection shaft as a fulcrum; and second weight bodies arranged between the facing both supports. Each support is provided with a support wall part 51 for guiding and sliding the weight body formed in a nearly elliptical shape. The second weight body is provided by engaging the shaft parts at both ends with the facing support wall part, and by being supported movably between one end to the other end of the support wall part. <P>COPYRIGHT: (C)2013,JPO&INPIT |
