Abstract:
1. A headphone having a band through which a twin-cord wiring connecting a pair of headphone units is inserted, the pair of headphone units being attached to both ends of the headphone, and at least one of the pair of headphone units being made slidable relative to the band, comprising: a hollow slider that supports the slidable headphone unit, accommodates an extension part of the twin-cord wiring for connecting wiring positioned at the end of the band with the slidable headphone unit, and includes an engaged part for regulating a sliding range of the headphone unit in the longitudinal direction of the band; a slider guide fixed to an end part of the band and inserted through the slider, for guiding a sliding motion of the slider when the headphone unit is sliding relative to the band, wherein the sliding motion is regulated by friction and is stepless; and an engaging part having approximately the same width as the width of the engaged part in a direction orthogonal to the longitudinal axis of the slider, attached to the end part of the band, and engaged with the engaged part so as to be locked to the end part of the engaged part when the headphone unit is sliding relative to the band.
