The horizontal portions 4 and 4 ′ facing each other and the horizontal portions
It has a substantially I-shaped cross section consisting of a vertical portion 5 connecting the respective central portions of 4, 4 ', and the connecting portion between the horizontal portion 4, 4'and the vertical portion 5 forms a three-sided portion 6, 6'. I am configuring. And the vertical part 5
Has a width varying in the length direction of the reinforcing member 3.

形成されている。To describe the shape of the reinforcing member 3 in more detail, one horizontal portion 4 extends straight in the longitudinal direction of the reinforcing member 3, and the other horizontal portion 4'partially extends in the longitudinal direction. It is inclined with respect to it. The warp yarn 7 extending in the length direction and the weft yarn 8 orthogonal to the warp yarn 7 are woven. Thus, the vertical portion 5 has a wide portion 9, a narrow portion 10, and the wide portion 9
An inclined portion 11 is formed by gradually changing the width between the narrow portion 10 and the narrow portion 10.

部４の最初の半分を織成する。The weaving sequence of the reinforcing member 3 will be described with reference to FIG. 3. The weft yarn 8 is first driven into the warp yarn 7 in the forward direction to weave half of the horizontal portion 4, half of the vertical portion 5 and half of the horizontal portion 4 '. Then, it is driven in the opposite direction to weave said half of the horizontal portion 4 '. Next, the weft thread 8 is folded back at the three-sided portion 6'and is driven again in the forward direction, weaving the other half of the horizontal portion 4 ', and further driven in the opposite direction,
The remaining half of the horizontal section 4 ', the vertical section 5 and the other half of the horizontal section 4 are woven. The weft threads 8 are then driven in again in the forward direction, weaving the remaining half of the horizontal section 4,
Further, it is folded back at the three-sided portion 6 and is driven in the opposite direction to form the first half of the horizontal portion 4.
以下これを繰返すことにより、中央部が一重で両縁部

の間たて糸７の密度は一定で変化することがない。Thus, in the reinforcing member 3 of the present invention, as shown in FIG. 3, in the wide portion 9, the weft threads 8 are woven over the entire group of the warp threads 7 and are folded back at the warp threads 7 at both edges. In the inclined portion 11, the weft thread 8 is folded back at the edge warp thread 7 at the upper edge in the figure, but is not woven into the edge warp thread 7 at the lower edge, and is more inward than that. Turns back at 7. Then, the folded position gradually shifts to the inner warp yarn 7, whereby the weaving width of the entire reinforcing member 3 is gradually reduced. Since the widths of the horizontal portions 4 and 4'are made constant, the reduction of the weaving width appears as the reduction of the width of the vertical portion 5, and the inclined portion 11 is formed. Further, in the narrow width portion 10, the warp yarn 7 at a position corresponding to the weaving width of the narrow width portion 10 is woven back to form the narrow width portion 10 having a predetermined width. During this time, the density of the warp yarn 7 is constant and does not change.
強化部材３を織成した後、傾斜部11及び細幅部10にお

おいて必要に応じて切除すれば良い。After weaving the reinforcing member 3, the warp yarns 7 not woven into the weft yarns 8 in the inclined portion 11 and the narrow width portion 10 may be cut off as necessary in a later step.

の強化部材となる。Further, since the reinforcing member 3 of the present invention is integrally formed as a whole and is not sewn, it is excellent in strength, and the composite material is partially inferior in strength and is not broken by an external force. Further, the warp yarn 7 woven into the vertical portion 5 in the wide width portion 9 does not partially constitute the vertical portion 5 in the inclined portion 11 and the narrow width portion 10, but the warp yarn 7 continues continuously as it is. Since the horizontal portion 4 is formed via the three-sided portion 6, the vertical portion 5 and the horizontal portion 4 are continuous regardless of the change in the number of warp yarns in the vertical portion 5, and become an integral reinforcing member as a whole.

比率で幅を変化させることができる。Further, the reinforcing member 3 of the present invention includes a vertical portion 5 having a variable width.
Since the density of the warp yarn 7 and the weft yarn 8 does not change at all and the thickness does not change, the width can be changed at an extremely large ratio.
