An automatic reel for earphone

PURPOSE: An automatic cord winder for an earphone is provided to prevent disconnection or tangles of an earphone cord by adopting a method in which an earphone cord is reeled based on an earphone terminal fixed to a terminal fixing part. CONSTITUTION: A terminal groove for inserting an earphone terminal is formed on one side of a terminal fixing part(20). A rotating part(30) is formed inside a case. The terminal fixing part is movably combined with one side of the rotating part. A first elastic member(40) provides rotational elastic force to the rotating part. A winding part(50) rotates with the rotating part while being an upper end portion of the rotating part. An earphone terminal fixed to the terminal fixing part is inserted into the case with movement of the terminal fixing part. The rotating part is rotated by a first elastic member. The earphone cord connected to the earphone terminal is reeled in the winding part.
