The frame main body portion includes an annular ring holding portion 3 that is located around the entire circumference of the ring mounting hole 4 and holds the guide ring. In the present embodiment, the frame main body portion includes the support leg portion 2 that is located between the ring holding portion 3 and the mounting leg portion 1 and that connects the ring holding portion 3 and the mounting leg portion 1. In the following description, the direction of the center line of the fishing rod is the front-rear direction, the rod tip side is the front side, and the rod butt side is the rear side. Further, the mounting leg 1 side is the lower side, and the frame main body side is the upper side. That is, the direction close to the center line of the rod body of the fishing rod is the lower side, and the direction away from the rod body radially outward is the upper side. Further, the circumferential direction of the rod body may be referred to as the width direction together with the left-right direction. 3 to 5, the left-right direction, the front-back direction, and the up-down direction are indicated by arrows X, Y, and Z, respectively. The guide frame may be composed of a plurality of members, but in the present embodiment, it is composed of one member. Therefore, the mounting leg portion 1 and the frame main body portion are made of one member and are integrally formed. The material of the guide frame is arbitrary and is made of metal or synthetic resin. In particular, a sintered body is preferable, and a sintered alloy is preferable.

<Mounting leg 1>
The mounting leg portion 1 extends in the front-rear direction. In the present embodiment, the mounting leg portion 1 has a one-leg structure extending only to the rear side with respect to the frame body portion, but may have a two-leg structure extending to both front and rear sides. The lower surface of the mounting leg portion 1 is curved in a concave shape toward the upper side along the left-right direction so as to easily follow the outer peripheral surface of the rod body. The upper surface of the mounting leg portion 1 is gradually lowered toward the rear side, and the vertical dimension of the mounting leg portion 1 is determined by lowering the upper surface toward the rear side in this way. Is gradually getting smaller toward. The width, which is the lateral dimension of the mounting leg 1, is gradually narrowed toward the rear side. The mounting leg portion 1 is wound around and fixed to the outer peripheral surface of the rod body by, for example, a winding thread.

<Ring holder 3 and support leg 2>
The frame main body portion extends upward from the front end portion of the mounting leg portion 1. The frame body portion extends upward while curving from the front end portion of the mounting leg portion 1. The frame main body may stand up at a substantially right angle to the mounting leg 1, but in the present embodiment, it stands up while inclining to the front side. Therefore, the frame body is inclined to the front side.

The lower end of the support leg 2 is connected to the front end of the mounting leg 1. The support leg 2 may have a one-leg structure, but in the present embodiment, it has a two-leg structure arranged side by side. The pair of left and right support legs 2 are symmetrical to each other. The left and right support leg portions 2 extend toward the upper side while gradually opening to the left and right. The separation distance between the two support leg portions 2 gradually increases toward the upper side, and the left and right support leg portions 2 are substantially V-shaped as a whole. The left and right support legs 2 are connected to the front ends of the mounting legs 1, respectively. The left and right support legs 2 are separated from each other at their lower ends in the left and right directions and independently extend upward. However, the left and right support leg portions 2 may be integrated at the lower end portion thereof without being separated left and right. The upper ends of the left and right support legs 2 are connected to the left and right sides of the ring holder 3, respectively. The left and right support leg portions 2 extend linearly from the mounting leg portion 1 toward the ring holding portion 3 when viewed along the front-rear direction as shown in FIG. 5, and the left and right support leg portions 2 are It extends in the tangential direction of the ring holding portion 3 from the front end portion of the mounting leg portion 1 toward the ring holding portion 3. A through hole 5 surrounded by the ring holding portion 3, the left and right support leg portions 2 and the mounting leg portion 1 is formed, and the through hole 5 penetrates back and forth.

The ring holding part 3 is endless and annular. In this embodiment, since the circular guide ring is held, the ring mounting hole 4 is circular and the ring holding portion 3 is also circular. The ring holding portion 3 is located around the entire circumference of the ring mounting hole 4. The wall surface of the ring mounting hole 4 is an inner peripheral surface of the ring holding portion 3 and a holding surface for holding the outer peripheral surface of the guide ring. The wall surface of the ring mounting hole 4 is continuous over the entire circumference and has no discontinuous portion. It should be noted that the wall surface of the ring mounting hole 4 may be formed with irregularities, for example, a concave portion for accumulating adhesive may be formed. The cross-sectional shape of the outer peripheral surface of the ring holding portion 3 may be substantially constant, but in the present embodiment, as shown in FIG. 6, the cross-sectional shape of the outer peripheral surface at the uppermost portion and the outer peripheral surface at the lowermost portion of the ring holding portion 3. The cross-sectional shape of is different. At the uppermost part of the ring holding part 3, the rear part of the outer peripheral surface is largely curved along the front-rear direction, while at the lowermost part of the ring holding part 3, the front part of the outer peripheral surface is largely curved along the front-rear direction. doing. As described above, the cross-sectional shape of the ring holding portion 3 is different between the uppermost portion and the lowermost portion.

The cross-sectional shape when the ring holding portion 3 is cut in the direction orthogonal to its circumferential direction, that is, the radial direction of the ring mounting hole 4, and the cross-sectional shape when the support leg 2 is cut in the horizontal plane are different from each other. , All are non-circular. The cross-sectional shape of the mounting leg 1 when cut in the direction orthogonal to the front-rear direction is different from the cross-sectional shape of the ring holding portion 3 and the support leg 2.

As described above, the entire guide frame is composed of one member, and therefore the mounting leg portion 1 and the frame body portion are integrally formed. Then, in the present embodiment, the entire guide frame is hollow, and the entire guide frame is a hollow portion. The hollow portion includes a hollow hole that is an internal space and an outer wall portion that surrounds the hollow hole. The number of hollow holes in the guide frame is one as a whole, and constitutes one space that communicates from the ring holding portion 3 to the mounting leg portion 1. That is, the entire ring holding portion 3, the entire left and right support leg portions 2, and the entire mounting leg portion 1 are hollow portions, and the cavity hole 13 in the ring holding portion 3 and the left and right support leg portions are formed. The hollow hole 12 in 2 and the hollow hole 11 in the mounting leg 1 communicate with each other to form one internal space as a whole. The hollow hole continues from the ring holding portion 3 through the support leg portion 2 to the mounting leg portion 1. The hollow hole of the guide frame is a space sealed by the outer wall portion.

In detail, the number of the hollow holes 11 of the mounting leg portion 1 is one as a whole, and it gradually expands from the rear end portion to the front end portion in two directions of the left-right direction and the vertical direction. The hollow holes 11 of the mounting leg portion 1 are connected to the respective hollow holes 12 of the left and right support leg portions 2 at the front end portion of the mounting leg portion 1. Therefore, the hollow hole 11 of the mounting leg portion 1 branches left and right at the front end portion of the mounting leg portion 1 and communicates with the hollow hole 12 of each support leg portion 2. In other words, the hollow holes 12 of the left and right support legs 2 join the hollow holes 11 of one mounting leg 1 at the front end of the mounting leg 1. That is, the front end portion of the mounting leg portion 1 is the confluence portion S, and at the confluence portion S, the cavity holes 12 of the left and right support leg portions 2 confluence and become the cavity hole 11 of the mounting leg portion 1. ing. Then, as shown in FIGS. 11 and 12, the cross-sectional shape greatly changes from the front end portion of the mounting leg portion 1 to the left and right support leg portions 2, and the hollow ratio also greatly changes. The hollow ratio is the area ratio of the hollow portion in the entire cross section, and is the ratio of the area of the cross section of the hollow hole to the area of the entire cross section in the cross sectional shape.

The upper ends of the left and right support legs 2 are connected to the left and right sides of the ring holder 3, respectively. The ring holding part 3 is a hollow part as a whole, and the hollow hole 13 of the ring holding part 3 is continuous over the entire circumference of the ring mounting hole 4. The hollow hole 13 of the ring holding portion 3 and the hollow holes 12 of the left and right support leg portions 2 communicate with each other. That is, the cavity hole 12 of the left support leg portion 2 communicates with the cavity hole 13 of the ring holding portion 3 at the upper end portion of the left support leg portion 2, and the cavity hole 12 of the right support leg portion 2 is The upper end portion of the right support leg portion 2 communicates with the hollow hole 13 of the ring holding portion 3. The lower part of the ring holding part 3 connects the upper end parts of the left and right support leg parts 2 to the left and right below the ring mounting hole 4, and the upper part of the ring holding part 3 is the upper end part of the left and right support leg parts 2. The parts are connected to the left and right above the ring mounting hole 4. Therefore, at the upper ends of the left and right support legs 2, the cavity hole 12 of the support leg 2, the cavity hole 13 at the upper part of the ring holding part 3 and the cavity hole 13 at the lower part of the ring holding part 3 merge, respectively. .. That is, the upper end portions of the left and right support leg portions 2 are the merging portions S, and at each merging portion S, the cavity hole 12 of the support leg portion 2 and the cavity hole 13 of the ring holding portion 3 merge and are integrated. Has become. In other words, the cavity hole 13 in the upper part of the ring holding part 3 is the cavity hole 12 in the left and right support leg parts 2 and the cavity hole 13 in the lower part of the ring holding part 3 at the upper ends of the left and right support leg parts 2, respectively. Has branched to. Then, as shown in FIG. 8, the cross-sectional shape changes greatly at the upper end portions of the left and right support leg portions 2, and the hollow ratio also changes greatly.

As described above, in the present embodiment, there are a total of three merging portions S, that is, the front end portion of the mounting leg portion 1 and the upper end portions of the left and right support leg portions 2, and at each merging portion S, the thickness of the outer wall portion is almost the same. The cross-sectional shape changes without change and the hollow ratio changes. As a result, it is possible to suppress an increase in weight at the merging portion S, and it is possible to reduce the weight while ensuring the strength of the guide frame. Further, since the entire ring holding portion 3 is a hollow portion and the wall surface of the ring mounting hole 4 is continuous over the entire circumference, the ring holding portion 3 can firmly hold the guide ring.

Furthermore, since the cross-sectional shape is expanded and the hollow ratio is expanded in the connecting portion between the ring holding portion 3 and the left and right supporting leg portions 2, it is possible to easily secure the strength of the connecting portion while suppressing an increase in weight. it can. In addition, as shown in FIGS. 9 to 11, the supporting leg portion 2 has an enlarged cross-sectional shape at the lower end portion and an enlarged hollow ratio, so that the supporting leg portion 2 and the mounting leg portion 2 and the mounting leg portion are prevented from increasing in weight. Sufficient strength can be secured in the connection portion with the portion 1. The mounting leg 1 has a flat shape that is wide in the left-right direction with respect to the up-down direction, but has a hollow shape with a single hollow hole and a substantially constant wall thickness, which is sufficient while suppressing an increase in weight. It is possible to secure sufficient strength and a large mounting surface for the rod body.

Next, a guide frame according to the second embodiment of the present invention will be described with reference to FIGS. 14 to 25. However, detailed description of the same configuration as the first embodiment will be omitted. In FIGS. 15 to 17, arrows X, Y, and Z indicate the left-right direction, the front-rear direction, and the up-down direction, respectively. The guide frame according to the present embodiment has a configuration that does not substantially include the support leg portions 2, and the frame body portion substantially includes only the ring holding portion 3. The lowermost part of the ring holding part 3 is connected to the mounting leg part 1.

The mounting leg portion 1 extends in the front-rear direction with respect to the ring holding portion 3 and has a two-leg structure. Although the front and rear directions of the guide frame are arbitrary and can be used in any of the directions, one mounting leg portion 20 will be described as the front side and the other mounting leg portion 21 will be described as the rear side. Unlike the first embodiment, the center line of the ring mounting hole 4 is not tilted forward but along the front-rear direction. Therefore, the ring holding portion 3 stands up at a substantially right angle to the mounting leg portion 1 as a whole. However, as shown in FIGS. 14 and 18, the lowermost front surface of the ring holding portion 3 rises while smoothly curving from the upper surface of the front mounting leg portion 20, and the lowermost portion of the ring holding portion 3 is The rear surface stands up at a substantially right angle without being curved with respect to the upper surface of the rear mounting leg portion 21.

A pair of left and right guard walls 22 are formed from the rear surface of the ring holding portion 3 to the upper surface of the rear mounting leg portion 21. The pair of left and right guard walls 22 extends rearward from both sides of the lower portion of the rear surface of the ring holding portion 3. The pair of left and right guard walls 22 are formed in a substantially V shape with the distance between them gradually increasing toward the upper side when viewed from the rear side as shown in FIG. 16. The upper surface of the guard wall 22 is gradually lowered toward the rear side as shown in FIG.

The guide frame of the present embodiment is also composed of one member, and the mounting leg portion 1 and the ring holding portion 3 are integrally formed as one member. Further, the entire guide frame is a hollow portion. The number of the hollow holes is one as a whole, and constitutes one internal space which communicates from the ring holding portion 3 to the mounting leg portion 1. Specifically, as shown in FIGS. 18 and 24, the number of the cavity holes 30 and 31 of the front and rear mounting leg portions 20 and 21 is one as a whole, and they extend in the front-rear direction. The hollow hole 13 of the ring holding portion 3 is annular and surrounds the ring mounting hole 4 and is continuous over the entire circumference of the ring mounting hole 4. The hollow holes 30 and 31 of the mounting leg portions 20 and 21 are connected to the hollow holes 13 of the ring holding portion 3 at the front and rear central portions of the mounting leg portions 20 and 21. Therefore, at the lowermost part of the ring holding portion 3, the cavity hole 30 of the front mounting leg portion 20, the cavity hole 31 of the rear mounting leg portion 21, and the cavity hole 13 of the ring holding portion 3 merge to form a single hole. It is the confluence part S that joins.

Further, as shown in FIGS. 19 to 24, the pair of left and right guard walls 22 are also hollow portions. The cavity holes 32 of the pair of left and right guard walls 22 are connected to the cavity holes 13 of the ring holding portion 3 at their front end portions. The front end portions of the pair of left and right guard walls 22 are merging portions S where the cavity hole 32 of the guard wall 22 and the cavity hole 13 of the ring holding portion 3 merge. Further, as shown in FIG. 23, the cavity holes 32 of the pair of left and right guard walls 22 are connected to the cavity holes 30 and 31 of the mounting leg portions 20 and 21 at their lower end portions. Therefore, the lower end portions of the pair of left and right guard walls 22 are a merging portion S where the hollow holes 32 of the left and right guard walls 22 and the hollow holes 30 and 31 of the mounting leg portions 20 and 21 merge. The cross-sectional shape when the guard wall 22 is cut along a horizontal plane along the front-rear, left-right direction changes from the upper side to the lower side as shown in FIGS. 19 to 24, and the cross-sectional shape of the cavity 32 also changes. ing.

The guide frame in the present embodiment also has the confluence S, and in the confluence S, the cross-sectional shape changes with the wall thickness of the outer wall hardly changing, and the hollow ratio changes. Therefore, it is possible to suppress an increase in weight at the merging portion S, and it is possible to reduce the weight while ensuring the strength of the guide frame.

<Manufacturing method>
