PURPOSE: An earphone storage device is provided to enable a user to easily adjust the length of an earphone to a desired length and to conveniently store the earphone. CONSTITUTION: An earphone storage device includes a winding part (120), a spiral spring (130), a pole component, and a cover component (150). The winding part forms a ratchet wheel for the winding of an earphone cord at the central part; is combined with a boss component to enable the ratchet wheel to be rotated in a case; and is equipped with a plug fixing component. The plug fixing component fixes the plug portion of an earphone. The spiral spring is inserted into the ratchet wheel in a way that one end is fixed to the case and the other end is fixed to the winding part, and elastically supports the winding part. The pole component is prepared at the case and caught in the teeth of the ratchet wheel, and selectively releases the rotational constraint of the ratchet wheel and therefore enables the ratchet wheel to be rotated in only one direction. The cover component is combined with the case and exposes the plug portion of the earphone, which is fixed to the winding part, to the outside by forming a through-hole at the central part. |
