Claims

[Scope of utility model registration request]

A clutch group having a first clutch that operates during forward gear shifting and a second clutch that operates during reverse gear shifting, a planetary gear group that includes a sun gear, a planetary gear, and a planetary carrier and ring gear that supports the planetary gear, and an input shaft. a first transmission shaft that is connected to the input shaft via a torque converter and transmits power to the planetary gear group via a clutch group; and a second transmission shaft that is directly connected to the input shaft via a lock-up clutch and directly drives the planetary gear group. A transmission shaft, a brake having a piston that fixes the carrier of the planetary gear group to a stationary member, and a one-way clutch that prevents rotation of the planetary carrier in one direction, and the brake and the one-way clutch are connected to the planetary gear group. The piston of the brake is disposed on the outer periphery of a boss portion which is disposed radially outward of the group in parallel with the inner surface of the transmission case and receives a bearing of an output shaft connected to the ring gear. automatic transmission.
