The present invention relates to an automatic line winding device for an electronic device. According to the present invention, when an earphone line is pulled, the earphone line is extended by the desired length, and when the earphone line is slightly pulled, the earphone line is rewound again. The automatic line reeling device for an electronic device comprises an upper bracket, an intermediate bracket and a lower bracket. A winding wheel for winding the earphone line is formed in an internal space between the upper bracket and the intermediate bracket. A ball track for guiding balls is directly formed on an upper surface of the winding wheel. An elastic member is installed on a lower part of the winding wheel. Accordingly, the structure is simple, and the number of components is reduced. Also, the winding wheel and the elastic member can be smoothly rotated. COPYRIGHT KIPO 2017 ...
