PROBLEM TO BE SOLVED: To provide a swing structure which has a simpler structure and is easy to assemble.SOLUTION: A plurality of short cylinders 11 are inserted into two parallel wires 20 along the longitudinal direction, only the short cylinder at a distal end among the plurality of short cylinders 11 is fixed to the wires 20, a pair of shaft parts 15 to be a turning shaft respectively or a pair of bearing parts 16 for receiving them are formed on respective end faces 13 and 25 of the two adjacent short cylinders, and a fitting structure of fitting the pair of shaft parts and the pair of bearing parts with each other is attained. By drawing one of the two wires 20, delivering the other, and turning the respective two adjacent short cylinders with each other by the turning shafts, the plurality of short cylinders are made to perform a swing operation as a whole.COPYRIGHT: (C)2013,JPO&INPIT【課題】より簡易な構造であり、かつ、組み立てが容易である首振構造体。【解決手段】並列された2本のワイヤ20に、その長手方向に沿って複数個の短筒体11を挿通し、複数個の短筒体11のうち先端にある短筒体のみをワイヤ20に固定し、隣接する2つの短筒体のそれぞれの端面13,25に、それぞれ回動軸となる一対の軸部15又はそれを受ける一対の軸受部16を形成し、それらの一対の軸部と一対の軸受部とを互いに嵌合する嵌合構造とし、2本のワイヤ20の一方を繰り寄せるとともに他方を繰り出して、それぞれの隣接する2つの短筒体を回動軸で互いに回動させることで、複数の短筒体を全体として首振動作させる。【選択図】図7
