It is an object of the invention to provide a power transmission apparatus appropriately controlled in a creep state. A control device is provided, which controls to gradually increase a clutch torque until the vehicle speed reaches the predetermined speed, and controls the internal combustion engine to gradually increase a magnitude of an output torque from an output shaft following increase of a clutch torque, at a vehicle speed of not more than a predetermined speed, if a creep state continues for more than predetermined time after an operation of brake pedal BP, which instructs deceleration of a vehicle based on a magnitude of a driver's operation, is stopped.
