However, in the guide frame for fishing as shown in Patent Documents 1 and 2 described above, for example, when the ribs are provided integrally with the frame body and manufactured as a reinforcing structure, the reinforcing fibers arranged in a predetermined direction in the ribs are sufficiently flowed. There is a risk that it will not be lifted. Therefore, the reinforcing fibers contained in the resin in the ribs become insufficient, and there is a problem that the desired strength cannot be secured in the ribs.

The present invention has been made in consideration of such circumstances, and the object thereof is to improve the strength of the reinforcing rib itself, and to efficiently reinforce the entire guide frame for fishing, a guide frame for fishing, and a guide frame for fishing To provide a manufacturing method.

According to the guide frame for fishing according to the present invention, when the reinforcing rib is protruded and installed on the frame body, a fiber-reinforced resin containing a reinforcing fiber having an irregular direction is used, and the direction at the time of manufacture is changed. The irregularly arranged reinforcing fibers tend to flow into the portion of the reinforcing rib. Therefore, the filling rate of the reinforcing fibers in the reinforcing rib can be increased, and the strength of the reinforcing rib itself can be improved. Therefore, the whole guide frame for fishing can also be reinforced efficiently.

(2) The fiber-reinforced resin preferably contains reinforcing fibers having irregular lengths.

In this case, in the case where the reinforcing ribs are protruded and installed on the frame body, a fiber-reinforced resin containing an irregular length in addition to the direction of the reinforcing fibers is used, and the direction and length are irregularly arranged at the time of manufacture. The reinforcing fibers used become easier to flow into the reinforcing rib part more reliably. Therefore, the filling rate of the reinforcing fibers in the reinforcing rib can be further increased, and the strength of the reinforcing rib itself can be improved.

(3) The reinforcing rib may be provided over the entire circumference of the ring holding portion.

In this case, since the ring holding part of the frame body is reinforced by the reinforcing rib, the holding force of the guide ring by the ring holding part can be increased. It is possible to prevent the ring holding part from being damaged by the load of the fishing line through the guide ring for guiding the fishing line.

(4) The frame body may have a supporting leg extending in a direction away from the outer peripheral surface of the fishing rod to support the ring holding unit, and the reinforcing rib may extend in the long axis direction of the supporting leg unit. do.

By setting it as such a structure, since the support leg part of the frame body is reinforced by the reinforcing rib extending in the major axis direction, it becomes reinforcement with respect to the force received from a guide ring, and the support force of a ring holding part can be raised.

(5) The fiber-reinforced resin may be a plurality of laminated prepreg sheets, and the frame body and the reinforcing ribs may be formed by heating and pressing the prepreg sheet.

In this case, by providing a plurality of layers of prepreg sheets, the reinforcing ribs can be sufficiently filled with reinforcing fibers during production. Further, the connection portion between the frame body and the reinforcing rib can be sufficiently reinforced.

(6) In the method for manufacturing a guide frame for fishing according to the present invention, in the method for manufacturing a guide frame for fishing according to any one of (1) to (5), a convex shape of the reinforcing rib is formed. A first mold having a recess, a step of setting a second mold facing the first mold, and a prepreg sheet on which a plurality of the fiber-reinforced resins are laminated between the first mold and the second mold disposing, heating the prepreg sheet, bringing the first mold and the second mold close to each other and pressing the prepreg sheet against the first mold to press the prepreg sheet into the It is characterized in that it has a step of flowing inward of the concave portion.

According to the manufacturing method of the guide frame for fishing which concerns on this invention, the manufactured guide frame for fishing has the effect similar to Claim 1. That is, at the time of manufacture, since the reinforcement fiber with an irregular direction at least in a prepreg sheet spreads and fills the whole recessed part of a 1st metal mold|die, sufficient intensity|strength for a reinforcement rib can be ensured.

6 to 8, in the guide frame 1 for fishing of the present embodiment, as described above, the frame body 10 and the reinforcing ribs 20 are reinforcing fibers 13 with irregular directions and lengths. It is formed by the fiber-reinforced resin 14 made of the prepreg sheet 15 having As preparation for manufacture, the prepreg sheet 15 is cut into a predetermined shape, and this is superimposed so that it may become a multiple layer. In addition, the structure, such as the number of sheets (number of layers) of the prepreg sheets 15 superimposed, can be set suitably. The number of layers of the prepreg sheet 15 is determined according to conditions, such as the load acting on the guide frame 1 for fishing at the time of use, and the bending characteristic of a fishing rod.

As the prepreg sheet 15 used here, a general reinforced plastic molding material in which a reinforcing fiber 13 such as carbon fiber or glass fiber is uniformly impregnated with a thermosetting resin such as epoxy and heated or dried to a semi-hardened state. is employed
