A gear ratio-controlled stepless transmission is provided to generate a gear ratio higher than a gear ratio of a power plate and a differential gear without use of a transmission gear. A stepless transmission includes a power transmission bar(3), a power connecting bar(4), and a power driving bar(5). A power plate is directly connected to a crank shaft. A slide rail is prepared in the power plate. The power transmission bar is connected to the slide rail, and is vertically operated about a central axis of the power plate. The slide rail is prepared in the power transmission bar. The power connecting bar is connected to the slide rail, and is operated according to the slide rail of the power transmission bar.
