  "textContent": "A power transmission device includes an input shaft, an output shaft, a differential device including a first rotation element connected to the input shaft, a second rotation element connected to the output shaft, and a third rotation element, and a continuously variable transmission unit including a conversion unit configured to convert rotational power of the third rotation element into another power and a reconversion unit configured to reconvert the converted other power into the rotational power and supply the reconverted rotational power to the output shaft. A control device of the power transmission device generates a control signal of the continuously variable transmission unit such that the other power generated by the conversion unit exceeds the other power input to the reconversion unit.",
