Abstract
A first helical gear (40) is supported by a first rotation shaft (4), and a second helical gear (13) is supported by a second rotation shaft (14). A rotation body (6, 7) comprising a third helical gear (7) which meshes with the first helical gear (40), and a fourth helical gear (6) which meshes with the second helical gear (13), is supported by an intermediate shaft (5). The rotation body (6, 7) is further supported by a thrust bearing (10, 11) in a direction along the intermediate shaft (5). The average radius R of the thrust bearing (10, 11) is determined according to the direction of the thrust load acting on the third helical gear (7), the direction of the thrust load acting on the fourth helical gear (6), and an angle &thgr;2 subtended by the application point of these thrust loads.
