PURPOSE:To enable a centrifugal oil pressure to be canceled by compact construction, by providing a partition, for forming a centrifugal oil pressure canceling pressure oil chamber in one clutch, and forming a cylinder part in the both clutch in the partition. CONSTITUTION:A power transmission gear has the first actuator, which operates the first clutch 5 connecting an input shaft 34 with the second retainer 3, while the second actuator, which operates the second clutch 13 connecting the input shaft 34 with the third retainer 4, and each actuator comprises pistons 8, 16, cylinders 9, 17, operating pressure oil chambers 10, 18 and centrifugal pressure oil chambers 12, 20. And the power transmission gear forms the second cylinder 17, for constituting the second operating pressure oil chamber 18 of the second actuator, in the external surface side of a partition 11 for the first centrifugal pressure oil chamber 12 of the first actuator. |
