For example, if power is not supplied to the rotation device 1 other than the rotation device 1 at the start end, the rotation speed of the rotation shaft 2 in the rotation device 1 at the start end and the rotation of the housing 3 or the rotation shaft 2 in the rotation device 1 at the end end. The generator is capable of outputting electric power due to a rotational difference from the number (generated when the load body W is connected to the terminal rotating device 1), and electric power is generated between the starting rotating device 1 and the load body W, which is an electric motor. Therefore, improvement in convenience and efficiency can be expected. [Selection] Figure 1
