PROBLEM TO BE SOLVED: To reduce a loss of a bearing by preventing skew.SOLUTION: A flexible meshing type gear device 100 has an external tooth gear 120 supported on an outer periphery of an excitation body 104 via an excitation body bearing 110. The excitation body bearing 110 comprises an inner ring 112, outer rings 118A, 118B, rollers 116A, 116B arranged between the inner ring 112 and the outer rings 118A, 118B, and retainers 114A, 114B holding the rollers 116A, 116B. The retainer 114A, 114B have extension parts 114AD, 114BD extending in a radial direction R of the excitation body bearing 110 from an end in an axial direction O. The extension parts 114AD, 114BD are opposed to the inner ring 112 in the axial direction O. |
