PURPOSE:To improve the mass-producing property of a transmission and diminish the cost thereof, by using a secured shaft to support the sun gear of a planet gear device through Oldham's coupling. CONSTITUTION:The sun gear 19 of a planet gear device 7 is supported by a secured shaft 21 through Oldham's coupling 22 so that the input torque acting to the planet gear device is equally distributed to plural planet gears 16 even if the tooth form accuracy and gyration center position accuracy of each gear are not made very high. As a result, the accuracy of processing and that of assembly are allowed to be lowered. The mass-producting property of a transmission is thus improved to diminish the cost thereof. |
