等張力化駆動装置。 An equal tension drive in which the rotation of the driving vehicle is transmitted to the driven vehicle by a power transmission member that is connected to the output shaft of a four-cylinder internal combustion engine and is extended between the driving vehicle and the driven vehicle, where rotational fluctuations occur periodically. In the apparatus, the outer peripheral edge shape of the driving wheel is formed into an elliptical shape having a major axis/minor axis ratio according to the tension fluctuation of the power transmission member due to the periodic rotational fluctuation, and the tension fluctuation is in an opposite phase to the tension fluctuation. An equal tension drive device, characterized in that the drive wheel is arranged to apply force to the power transmission member.
