A headband portion for headphones comprising: a headband spring having a plate-spring shape, and being bent in a substantially semicircular arc shape so as to be expandable in a longitudinal direction orthogonal to a plate width direction of the headband spring so that a central portion of the headband spring is disposed in a vicinity of a head top portion of a wearer and each of both end portions of the headband spring is arranged on each of both side head portions of the wearer, respectively, in response to the headphones being placed on the wearer's head, the headband spring comprising a plurality of oval punched portions along the longitudinal direction of the headband spring and bridge portions formed between the adjacent punched portions ; a pair of holding members having rigidity to restrict elastic deformation of the headband spring in a plate thickness direction of the headband spring , wherein the pair of holding members comprises a pair of pressing plate portions configured to hold both edge portions of the pair of both end portions in the plate thickness direction by inserting the pair of both end portions into the pair of holding members , the pair of pressing plate portions being arranged in parallel to each other, and the both edge portions being arranged in the plate width direction; a pair of stepped screws that passes through the bridge portions of both end side portions of the headband spring in the plate thickness direction and is screwed to the pair of holding members , and that holds the headband spring movably in an axial direction of the pair of stepped screws with gaps between flange portions of the pair of stepped screws and the pair of holding members , the gaps being larger than a plate thickness of the headband spring , and the both end side portions of the headband spring being arranged in the plate width direction. a headband spring having a plate-spring shape, and being bent in a substantially semicircular arc shape so as to be expandable in a longitudinal direction orthogonal to a plate width direction of the headband spring so that a central portion of the headband spring is disposed in a vicinity of a head top portion of a wearer and each of both end portions of the headband spring is arranged on each of both side head portions of the wearer, respectively, in response to the headphones being placed on the wearer's head, the headband spring comprising a plurality of oval punched portions along the longitudinal direction of the headband spring and bridge portions formed between the adjacent punched portions ; a pair of holding members having rigidity to restrict elastic deformation of the headband spring in a plate thickness direction of the headband spring , wherein the pair of holding members comprises a pair of pressing plate portions configured to hold both edge portions of the pair of both end portions in the plate thickness direction by inserting the pair of both end portions into the pair of holding members , the pair of pressing plate portions being arranged in parallel to each other, and the both edge portions being arranged in the plate width direction; a pair of stepped screws that passes through the bridge portions of both end side portions of the headband spring in the plate thickness direction and is screwed to the pair of holding members , and that holds the headband spring movably in an axial direction of the pair of stepped screws with gaps between flange portions of the pair of stepped screws and the pair of holding members , the gaps being larger than a plate thickness of the headband spring , and the both end side portions of the headband spring being arranged in the plate width direction. <EOS>
