<P>PROBLEM TO BE SOLVED: To reduce the influence of deformation of external teeth constituting an external gear. <P>SOLUTION: In a flexible meshing-type type gear device 100 including an excitation body 104, an external gear 120, a speed-reducing internal gear 130A, and an output internal gear 130B, the external gear 120 includes first and second external teeth 124A, 124B which are engaged with internal teeth 128A, 128B of the speed-reducing internal gear 130A and the output internal gear 130B, respectively, and are adjacently provided in mutual tooth trace directions Y. First and second external teeth 124A, 124B have an inner end IE facing an external tooth neighboring in a tooth trace direction Y and a center part C other than the inner end IE, respectively. Tooth height h1 of the inner end IE is smaller than tooth height h2 of the center part C. <P>COPYRIGHT: (C)2013,JPO&INPIT |
