PURPOSE: An earphone cable winding device is provided to reduce manufacturing costs by including a through-hole in a main body. CONSTITUTION: A main body(10) comprises two lead holes(11,12) in the outer circumference of a cylinder structure. A drive wheel(30) is accepted in the main body to be possible to rotate. The drive wheel comprises a tooth form(32) and a torsion spring(36). A winding reel(40) is installed in order to be interlocked with the drive wheel. A cover is combined in an opening surface of the main body. A concave grove which is interlocked with the drive wheel is formed in an internal plate. |
