    Abstract: A variable-speed speed increaser includes: an electric driving device which is configured to generate a rotational driving force; and a transmission device which is configured to change the speed of the rotational driving force generated by the electric driving device and transmit the changed rotation driving force to a driving target. The transmission device includes: a sun gear which is configured to rotate about an axis; a sun gear shaft which is fixed to the sun gear and extends in an axial direction around the axis; a planetary gear which is configured to mesh with the sun gear, revolve around the axis and rotate about a center line of the planetary gear; an internal gear which includes a plurality of teeth aligned annularly around the axis and is configured to mesh with the planetary gear; a planetary gear carrier; and an internal gear carrier.
