Abstract
A band comprising many beam portions and arcuate hinge portions formed integrally so as to be alternately arranged, a fitting force being obtained at least due to the returning force of the hinge portion so that the band can be expanded even with a small force and, in spite of the repeated use over a long period, the fitting force and winding action will not deteriorate and the band will not crack. The bands are connected symmetrically to both ends of a top band and are utilized as head bands for headphones.
