Abstract: There is disclosed an apparatus for winding a cord, and more particularly, an apparatus for winding a cord, in which a winding operation and a wind stopping operation are performed by pulling the cord of an ear-microphone of a portable cordless telephone. The cord winding and the wind stopping operations can be performed by a cord pulling operation without a separate operation of a release button, thereby providing convenience to the user. Further, while the ball is moved along the guide grooves, the winding and stopping operations are performed. Therefore, the ball functions as a moving bearing upon a rotation operation of the bobbin so that the bobbin is facilely rotated, thereby preventing an erroneous operation of the apparatus.
