PROBLEM TO BE SOLVED: To provide a blade member of an impeller for conveying paper sheets, capable of suppressing plastic deformation to enhance bending durability and recoverability.SOLUTION: A blade member 20 of a paper sheet conveying impeller 1 contacts and conveys a paper sheet. At least one blade member 20 of the paper sheet conveying impeller 1 is disposed so as to protrude from an outer peripheral surface of a rotatable cylindrical member 10. The blade member 20 of the paper sheet conveying impeller 1 includes a blade member main body 21 and a core wire 25. The blade member main body 21 is made of a thermosetting polyurethane elastomer. The core wire 25 is made of polyester fibers. At least a part of the core wire 25 is embedded in the blade member main body 21. A plurality of core wires 25 are arranged side by side in an axial direction G of a rotating shaft 11.SELECTED DRAWING: Figure 1 【課題】塑性変形を抑制して屈曲耐久性および復元性を高めた紙葉類搬送用羽根車の羽根部材を提供する。【解決手段】紙葉類搬送用羽根車１の羽根部材２０は、紙葉類に接触して搬送する。紙葉類搬送用羽根車１の羽根部材２０は、回転可能な筒部材１０の外周面から突出するように少なくとも１つ配置される。紙葉類搬送用羽根車１の羽根部材２０は、羽根部材本体２１と芯線２５とを備える。羽根部材本体２１は、熱硬化性ポリウレタンエラストマーからなる。芯線２５は、ポリエステル繊維からなる。芯線２５は、少なくとも一部が羽根部材本体２１の内部に埋設される。芯線２５は、回転軸１１の軸方向Ｇに並んで複数配列される。【選択図】図１
