PROBLEM TO BE SOLVED: To provide a shift gear device with components including an output shaft having a higher degree of freedom in design without impairing compactness. SOLUTION: The Coriolis motion shift gear device as a means for solving the problem comprises a first gear A1 of a tooth number n1 fixed to a housing 1, a fourth gear A4 of a tooth number n4 mounted to an output shaft 2 and an input shaft 1 arranged with their axial centers corresponding to one another, and a rotor 3 having a second gear A2 of a tooth number n2 and a third gear A3 of a tooth number n3 integrated with each other and journaled to the input shaft 1 at its inclined portion 1a so that the second gear A2 meshes with the first gear A1 and the third gear A3 meshes with the fourth gear A4. The input shaft formed as a hollow shaft has an eccentric portion on the inner peripheral face where the rotor is rotatably borne via a bearing member. COPYRIGHT: (C)2006,JPO&NCIPI
