PURPOSE: An automatic transmission is provided to suppress the wear of a sealing unit by installing a balancer to components which rotates for transmitting power during driving in order to maintain the rotation balance of the components. CONSTITUTION: A piston(70) pressurize a clutch plate in order to transmit power. A balancer(80) is installed to the piston and maintains the balance of the piston based on the center of a driving shaft. The balancer includes a running path(82) and a rotary body(84). The running path is formed to the circumferential direction of the driving shaft. The rotary body is contained in the running path. |
