<p>A reduction gear (1) has an externally toothed gear (20) that swings in a manner eccentric to an input shaft (10), an internally toothed gear (30) that has teeth slightly different in number from those of the externally toothed gear (20) and with which the externally toothed gear (20) meshes, a disc (50) for taking out only the component of rotation of the externally toothed gear (20), gear sections (41, 51) that transmit the component of the rotation of the externally toothed gear (20) from a disc (50) to an output shaft (40), and a reduction mechanism (300) that includes the output shaft (40). The disc (50), the gear sections (41, 51), and the output shaft (40) are arranged perpendicular to the axis of the input shaft (10).</p> |
