Abstract: A tension-torsion strap and a hub device having the same are provided to reduce the time required for the assembly and construction of the hub device with minimizing the reconstruction of the tension-torsion strap through a simple construction. A hub device(100) having a tension-torsion strap(600) includes a hub flexure(300), and a pitch cage(400). The pitch cage is connected to a blade(500). The hub flexure is fixed at a rotor shaft and has a hollow space inside thereof. The tension-torsion strap is inserted in the hub flexure. The hub flexure is coupled with the tension-torsion strap by a hub flexure connecting pin(310). The pitch cage is mounted on an opposite side of the tension-torsion strap inserted in the hub flexure. The pitch cage fixes the blade and the tension-torsion strap by the pitch cage pin.
