Are arranged by arranging the inclined fiber layers 26 so as to intersect the reinforcing fibers. In this case, the inclined fiber layer 26 may be disposed on the outer layer of the axial fiber layer 25 as shown in the figure, or may be distributed between the outer layer and the inner layer of the axial fiber layer 25. If they are distributed to the prepreg, inclined prepregs in which reinforcing fibers are aligned in different directions can be used. The thickness of the inclined fiber layer 26 is made larger than that of the main body layer 20 or the axial length fiber layer of the main body layer 20 in order to prevent the progress of rupture and improve the torsional strength (1.5 to 3.5).
The resin impregnation amount is preferably set to be larger than the axial length fiber layer of the main body layer 20 in order to prevent fiber tension and delamination. Further, the elastic modulus of the reinforcing fiber of the inclined fiber layer is arbitrary, but it is preferable to use a fiber that is higher than the axial length fiber layer of the main body layer 20 in order to compensate for the decrease in rigidity due to the formation of the through hole. However, the thickness, the resin impregnation amount, and the elastic modulus are not limited to the above examples, and can be set arbitrarily.

い。In addition, since the torsional rigidity is extremely reduced in the opening, an inclined fiber layer is inserted to reinforce the torsional rigidity. In this case, the inclined fiber layer may have a thickness of 1 ply or more and a thickness of 0.01 mm or more. Along with this, a circumferential reinforcing layer or an axial length reinforcing layer may be wound. In consideration of the workability at the time of winding, it is better to increase the resin impregnation amount than the main body layer,
If there is no problem in winding, it may be smaller than the main body layer.
The elastic modulus of the reinforcing fiber is preferably 1 ton / mm 2 or more, and more preferably equal to or more than the reinforcing fiber of the main body layer, in order to improve the shear elasticity.

It is configured by continuously arranging the inclined fiber layers 26. In this case, the prepreg constituting the reinforcing layer of the fishing line introduction part and the joint part may be composed of a plurality of sheets or a single prepreg. Therefore, it is preferable to increase the number of windings (thickness) on the fishing line introduction portion 2b side.
