A retracting/extending device of a headset is provided to stably fix a headset to an external ear of a user by protruding a retracting/extending member in an outer part of a main body housing in using the headset. A retracting/extending device(100) of a headset comprises a main body housing(110), a ear piece(120), and a retracting/extending member(150). The retracting/extending member is formed between the main body housing and the ear piece, and is retracted and extended from the main body housing according to a rotation of the ear piece. The ear piece moves closer to or away from the main body housing. A mounting groove(111) is formed on the main body housing. The retracting/extending member is mounted on the mounting groove, and includes a moving member(130) and a twist cam part(140). The moving member is rotated in the mounting groove.
