Abstract
A lock-up device is disposed between a front cover and a turbine in a torque converter to mechanically connect the front cover and the turbine. The lock-up device includes a clutch part and a release part. The clutch part is disposed in a power transmission path from the front cover to the turbine and is configured to be in a clutch-on state of transmitting a power from the front cover to the turbine in a set posture. The release part is configured to be actuated by a hydraulic pressure being increased in a space on a turbine-side of the piston to turn the clutch part from the clutch-on state to a clutch-off state and to block transmission of the power from the front cover to the turbine.
