<P>PROBLEM TO BE SOLVED: To provide a flexible meshing-type gear device requiring the deformation of an external toothed gear having a cylindrical shape, the device having increased service life. Ž<P>SOLUTION: The flexible meshing-type gear device 100 comprises external gears 120A, 120B arranged at the outer periphery of an exciter 104, first and second internal gears 130A, 130B with which the external gears 120A, 120B are internally meshed, exciter bearings (bearings) 110A, 110B arranged between the exciter 104 and the external gears 120A, 120B. The exciter bearings (bearings) 110A, 110B comprise rolling elements 116A, 116B having a cylindrical shape. The rolling elements 116A, 116B are divided into the first rolling element 116A corresponding to the portion of an external tooth 124A of the external gear 120A meshing with the first internal gear 130A, and the second rolling element 116B corresponding to the portion of an external tooth 124B of the external gear 120B meshing with the second internal gear 130B in the axial direction O.
