Abstract
A fluid transmission device includes a fluid transmission section capable of transmitting power transmitted to an input member to an output member via a working fluid, a lock-up clutch section capable of transmitting power transmitted to the input member to the output member via a friction engagement section, and a control unit configured to execute a torque ratio variable control that makes a torque ratio which is a ratio between torque output from the output member and torque input to the input member variable by adjusting a friction engagement state of the friction engagement section, when the fluid transmission section is in an operation state that the fluid transmission section amplifies torque input to the input member and outputs torque from the output member.
