An electric yo-yo toy has a pair of rotors, a main shaft provided between the centers of the pair of rotors, and a rotary shaft rotatably provided for the main shaft and around which a string member is wound. The rotor is provided with a drive motor, a gear mechanism for transmitting rotation of the drive motor to the rotary shaft, and a detecting device for detecting rotation of the rotor. The other rotor is provided with power supplies. The main shaft is provided with a conducting unit for electrically connecting the drive motor and the detecting device of the rotor and the power supplies of the other rotor. |
