Abstract: With the automatic transmission 10-1 for vehicle according to the present embodiment, since multistage transmission of eight forward gear stages can be obtained by means of four sets of planetary gear sets 12, 16, 18 and 20, four clutches C1 through C4 and three brakes B1 through B3, the transmission can be fabricated to be light in weight and made compact, wherein the mountability thereof in a vehicle can be improved. Further, as has been made clear in FIG. 1(b), since speed change in the respective gear stages can be carried out only by a shifting action of any two of the clutches C1 through C4 and brakes B1 through B3, the speed change control can be facilitated and it is possible to prevent a shock to the transmission from occurring.

Abstract: In a hydraulic servo for a clutch, a cancel plate is disposed on a second clutch drum that undergoes the same rotation as a second clutch drum provided with a cylinder portion, in such a fashion that the cancel plate is restricted from moving to a side opposite from a return spring in an axial direction. The first clutch drum is disposed, as a separate member, on the second clutch drum. A step portion of the second clutch drum prevents the first clutch drum from moving to a side opposite from the cancel plate. Due to the spring force of the return spring, the oil pressure in the cancel oil chamber and the oil pressure in the operating oil chamber, the force that presses the first clutch drum to the step portion is always greater than the force that presses the first clutch drum to the cancel plate side.
