PURPOSE:To perform fixation of high yield strength with limited compression force, by a method wherein a wedge bar is pressed into a tapered space surrounded by each of inner fillers and a tension material made of fiber- reinforced synthetic resin is held and fixed by the foregoing inner fillers and outer fillers. CONSTITUTION:End parts of plurality of FRP tension materials 1 are inserted into a sleeve 2 under a parallel state through a through hole 4 provided on the circumference of end plate 3 of the sleeve 2. Outer filler 5 is arranged between the each FRP tension material 1 and sleeve 2 and an inner filler 6 is arranged on a center side in the each FRP tension material 1. Then the FRP tension material 1 is held and fixed by the inner and outer fillers 6, 5 by pressing a wedge bar 7 into a tapered space surrounded by the inner filler 6. With this construction, the plurality of FRP tension materials 1 can be fixed at the same time and easily. In addition, as slopes of the tapered space and wedge bar 7 are made so as to fall within a range of 1/25-1/50, natural coming- off of the wedge bar 7 at the time when the wedge bar 7 has been pressed in is prevented and strong clamping force can be displayed.
