The eccentric oscillating gear device (1) is provided with: eccentric sections (10a); an oscillating gear (14) having insertion holes into which the eccentric sections (10a) are inserted as well as external teeth (14a); an outer tube (2); and a carrier (4). The outer tube (2) is configured from a material with a linear expansion coefficient larger than that of the material of the oscillating gear (14). The carrier (4) is disposed inside the outer tube (2) in the radial direction holding the oscillating gear (14). The outer tube (2) and the carrier (4) are capable of rotating concentrically relative to each other as a result of the oscillation of the oscillating gear (14) associated with the rotation of the eccentric sections (10a). |
