Abstract
The present invention provides a center crank eccentrically oscillating speed reducer enabled to increase the available cross-sectional area of a hollow hole, while the generation of large noises is suppressed, as compared with the conventional center crank eccentrically oscillating speed reducer. An eccentrically oscillating speed reducer (100) includes a case (110) configured to have internal teeth (111), a hollow crankshaft 120 configured to have an external gear 123, external gears 131 and (131) have external teeth 131a and 132a a carrier 140, and a transmission gear (160) configured to mesh with an input gear (150) and the external gear (123) and to transmit power transmitted from the input gear (150) to the external gear (123).
