PROBLEM TO BE SOLVED: To provide a Mckibben-type artificial muscle capable of preventing an elastic tube from rupturing, without making a braided tube lean to one side, even when a contraction operation is repeated.SOLUTION: A Mckibben-type artificial muscle, which is expanded/contracted by fluid pressure, includes an elastic tube 10 and a braided tube 20. The elastic tube 10 is made of an elastic body that is formed in a hollow cylindrical shape. The braided tube 20 is put into a braid-over-braid state by intertwisting a strand 21, containing deposited yarn 22, in such a manner that it can freely move onto an exterior wall of the elastic tube 10, and a crossed part 25 of the strand 21 is deposited.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】収縮動作を繰り返しても編組チューブが偏ることなく弾性チューブの破裂を防止可能なマッキベン人工筋を提供する。【解決手段】流体圧により伸縮するマッキベン人工筋は、弾性チューブ10と、編組チューブ20とからなる。弾性チューブ10は、中空の筒状に形成される弾性体からなる。編組チューブ20は、溶着糸22を含む糸状体21を弾性チューブ10の外壁の上に移動自在に縒り合わせて袋編みされると共に、糸状体21の交差部分25が溶着されてなる。【選択図】図1
