Description

  The present invention relates to a top guide used for a swing bar, a swing bar provided with the top guide, and a guide frame of the top guide.

  There are various types of so-called outer guide type fishing rods in which a fishing line guide for guiding the fishing line is mounted on the outside of the fishing rod. A large force acts on the fishing line guide from the fishing line. Therefore, the fishing line guide is required to have a strength that can withstand the force from the fishing line. On the other hand, since the weight of the fishing line guide greatly affects the weight of the entire fishing rod, weight reduction is also required. In particular, the top guide that is most worn on the tip has a great influence on the sensitivity and tone of the tip, and thus is required to be light while ensuring the necessary strength.

  In order to ensure the strength, it is advantageous to use a metal guide frame for holding the guide ring. For example, a conventional metal top guide includes a guide ring and a metal frame for holding the guide ring. Furthermore, a metal pipe separate from the frame is provided. The pipe is for attaching to the housing, and the housing is inserted and fixed inside. The frame is formed by punching a thin metal plate into a predetermined shape and then bending it. From the ring-shaped ring holding portion that holds the guide ring and the lower end that is the portion of the ring holding portion close to the casing A connecting piece portion extending and a bridge portion extending rearward from the ring holding portion are provided. And the front-end | tip part of the connection piece part of a flame | frame is inserted in the front-end opening part of a pipe, it joins by brazing, and the rear-end part of a bridge | bridging part is brazed to the outer peripheral surface of a pipe.

  However, in such a conventional top guide, the joint portion between the bridge portion of the frame and the pipe and the joint portion portion between the frame and the pipe are easily corroded, and the strength is likely to decrease due to secular change. There is a problem. In addition, there is a problem that fishing lines are likely to be entangled with these joint portions. Furthermore, since the frame is formed from a metal plate and is brazed to a separate pipe, it is difficult to reduce the weight without reducing the strength.

  Then, this inventor tried to form a guide frame integrally by forging. That is, the cylindrical attachment part for attaching to the housing and the ring holding part for holding the guide ring are integrally formed, and the guide frame is formed by forging as one member. By making the guide frame a forged product, the entire guide frame could be made extremely thin and light. In addition, because the thickness can be easily changed, the parts that require strength are relatively thick, while the other parts can be relatively thin. We were able to secure. Further, because of forging, the brazed portion can be eliminated, and corrosion at the brazed portion and yarn entanglement that tends to occur at that portion are prevented.

  However, since the mounting portion of the guide frame is extremely thin and has a small diameter, in the swing type fishing rod, i.e., in the configuration in which the moving guide is provided as the second guide behind the top guide, When housed inside the second bowl (hochi-mochi), there is a possibility that the rear portion of the top guide mounting portion may enter the bag insertion hole of the moving guide. If the rear part of the top guide mounting part enters the heel insertion hole of the moving guide, the top guide and the moving guide are stuck to each other, and the moving guide may be difficult to separate from the top guide. .

JP-A-9-131149

  Therefore, an object of the present invention is to prevent biting between the top guide and the moving guide used for the tip of the swinging ridge.

  The present invention has been made to solve the above-mentioned problems, and the top guide according to the present invention is a top guide that is attached to and fixed to the tip end portion of the tip of the swinging rod, and guides the fishing line. A guide frame which is a forged product for holding the guide ring, and the guide frame has a cylindrical mounting portion having a rod insertion hole into which the housing is inserted, and a diameter from the front end portion of the mounting portion. An annular ring holding portion having a ring mounting hole that is integrally extended outward in the direction and into which the guide ring is inserted and fixed, and the distance from the center line of the flange insertion hole on the outer peripheral surface of the rear portion of the mounting portion is It is characterized by a change in direction. The tip side is the front side and the buttock side is the rear side.

  In the top guide having such a configuration, the distance from the center line of the flange insertion hole on the outer peripheral surface of the rear portion of the attachment portion changes in the circumferential direction. Generally, when the distance from the center line of the flange insertion hole on the outer peripheral surface of the rear portion of the attachment portion changes in the circumferential direction, the cross-sectional shape of the rear portion of the attachment portion is not circular but noncircular. Further, when the distance from the center line of the flange insertion hole on the outer peripheral surface of the rear portion of the attachment portion changes in the circumferential direction, the thickness of the rear portion of the attachment portion also changes in the circumferential direction accordingly. A portion having a relatively large distance from the center line of the flange insertion hole and a portion having a relatively small distance are formed on the outer peripheral surface of the rear portion of the attachment portion. The thickness is relatively thick at the portion where the distance from the center line of the 竿 insertion hole is relatively large, and the thickness is relative at the portion where the distance from the center line of the 竿 insertion hole is relatively small. The thin part becomes thin. As described above, since the distance from the center line of the flange insertion hole on the outer peripheral surface of the rear portion of the mounting portion changes in the circumferential direction, even when the top guide approaches the moving guide from the front side when storing the rod, The thick part of the rear part contacts the moving guide. For this reason, the rear portion of the top guide mounting portion cannot enter the eaves insertion hole of the moving guide. In addition, even if the rear part of the mounting portion of the top guide can slightly enter the scissor insertion hole of the moving guide, it can be easily separated.

  In particular, it is preferable that the D-cut surface portion is formed on a part of the entire outer periphery of the rear portion of the attachment portion. The portion where the D-cut surface portion is formed is thinner than other portions. The D-cut surface portion may be a curved surface portion having a smaller curvature in the circumferential direction than the other peripheral surface portions of the attachment portion, or may be a flat surface portion having a curvature of zero. That is, the small curvature includes the case where the curvature is zero. Further, the curved surface portion may be a convex curved surface portion curved in a convex shape in the circumferential direction like the other peripheral surface portions of the outer peripheral surface, or conversely a concave curved surface portion curved in a concave shape in the circumferential direction. There may be. In any case, when the D-cut surface portion is formed on the outer peripheral surface of the rear portion of the attachment portion, the rear portion of the attachment portion becomes noncircular in cross-sectional view between the D-cut surface portion and the other peripheral surface portions, and from the center line of the flange insertion hole Can be easily changed. In the D-cut surface portion, the distance from the center line of the heel insertion hole is relatively small, and in the peripheral surface portion other than the D-cut surface portion, the distance from the center line of the heel insertion hole is relatively large. Therefore, the peripheral surface portion other than the D-cut surface portion comes into contact with the movement guide. Moreover, since the D-cut surface portion is partially thinned, the mounting portion can be reduced in weight.

  Furthermore, it is preferable that the D-cut surface portion is formed on a portion of the mounting portion on the side opposite to the ring. Of the entire circumference of the mounting portion, the side on which the guide ring is mounted, that is, the ring holding portion side is defined as the ring side, and the opposite side is defined as the opposite ring side. More specifically, out of the entire circumference of the outer peripheral surface of the mounting portion, when the position of the center line of the guide ring is 0 °, the 0 ° position is the ring side and the 180 ° position is the anti-ring side. It is. A ring holding portion is integrally formed on the ring side of the mounting portion, while there is no ring holding portion on the opposite ring side of the mounting portion. Therefore, the D-cut surface portion can be easily formed by forging on the side opposite to the ring as compared with the ring side. Further, when the D-cut surface portion is formed on the side opposite to the ring, for example, the position of the top guide on the side opposite to the ring compared to the case where the D-cut surface portion is formed at a position shifted by 90 degrees from the side opposite to the ring. Can be easily grasped. In many cases, for example, the winding end portion of the prepreg is present as a streak portion in the case, and the case is not uniform over the entire circumference, and directivity directed in a specific direction in the entire circumference is not provided. I often have it. In this way, when the housing has directivity, when mounting the top guide on the tip of the housing, the orientation and the orientation of the top guide are taken into consideration when considering the directivity and orientation of the housing. It is also done to align. For example, the prepreg winding end portion may be mounted with the orientation aligned such that the top guide is positioned on the ring side, which is the 0 degree position of the top guide, or on the counter ring side, which is the 180 degree position. Thus, when aligning the circumferential direction of the housing and the top guide, if the D-cut surface portion is formed on the side opposite to the ring of the mounting portion of the top guide, the 0-degree position of the top guide using the D-cut surface portion as a mark The streak-like portion of the housing can be easily adjusted to the 180 degree position. Further, when the top guide is set on the jig, the circumferential direction of the top guide can be easily performed by using the D-cut surface portion.

  Furthermore, it is preferable that the D-cut surface portions are formed so as to face each other on the portion on the opposite ring side and the portion on the ring side of the attachment portion. By forming the D-cut surface portions at two locations facing each other by 180 degrees, it is possible to further prevent the top guide and the moving guide from being fixed, and further reduce the weight. In addition, since the D-cut surface portion is also formed on the ring-side portion, it is even easier to align the circumferential direction of the housing and the top guide. It is even easier to perform positioning.

  Furthermore, the D-cut surface portion on the side opposite to the ring has a shape extending linearly long in the axial direction of the mounting portion, and the length in the axial direction of the D-cut surface portion on the opposite ring side is the D-cut surface portion on the ring side. It is preferable that the length is longer than the length in the axial direction. According to this structure, when aligning the orientation of the housing and the top guide by visual observation, the direction can be easily aligned with the D-cut surface portion on the opposite ring side as the main mark and the D-cut surface portion on the ring side as the sub-mark. it can. Moreover, it becomes even easier when positioning the top guide in the circumferential direction using a jig.

  Further, in the swing bar according to the present invention, the top guide as described above is attached and fixed to the tip of the tip hook, and the tip hook is provided with a moving guide behind the top guide. The rear portion of the mounting portion of the top guide is configured so as not to enter the insertion hole.

  The guide frame of the top guide for a swinging rod according to the present invention is a guide frame of a top guide that is attached and fixed to the tip of the tip rod of the swinging rod, and has a flange insertion hole into which the housing is inserted. A forged product comprising a cylindrical mounting portion and an annular ring holding portion integrally extending radially outward from the front end portion of the mounting portion and having a ring mounting hole into which a guide ring is inserted and fixed The distance from the center line of the flange insertion hole on the outer peripheral surface of the rear portion of the attachment portion changes in the circumferential direction.

  As described above, the distance from the center line of the flange insertion hole on the outer peripheral surface of the rear part of the mounting part of the guide frame, which is a forged product, changes in the circumferential direction, preventing the top guide and the moving guide from biting. can do.

The perspective view of the guide frame. The top view which looked at the same guide frame from the ring side. The bottom view which looked at the same guide frame from the non-ring side. BB sectional drawing of FIG. CC expanded end view of FIG. The principal part sectional view seen from the plane side showing the use state of the top guide. The end view corresponding to FIG. 7 which shows the use condition of the top guide.

  Hereinafter, a top guide according to an embodiment of the present invention will be described with reference to FIGS. The top guide in this embodiment is used by being attached to the tip of the tip of the swinging rod, and a guide ring 2 for directly guiding the fishing line and a guide for holding the guide ring 2 And a frame 3. The guide ring 2 is indicated by a two-dot chain line in FIG. 1, and the guide ring 2 is indicated by a solid line in FIG.

  The top guide is attached to the front end of the body 4 of the tip. The axial direction of the housing 4 is referred to as the front-rear direction, the heel side is the front side, and the buttock side is the rear side. Moreover, let the direction orthogonal to the axial direction of the housing | casing 4 be the left-right direction in the planar view seen from the ring side like FIG. The axial direction (front-rear direction) of the housing 4 is the direction of the center line of the housing 4 and is the direction of the center line 51 of the rod insertion hole 13 described later.

  The guide ring 2 is, for example, a circular ring as shown by a two-dot chain line in FIG. However, the shape of the guide ring 2 is arbitrary, and may be an ellipse or an oval, and in any case is a ring shape (annular). In the present embodiment, the case where the guide ring 2 is circular will be described. The guide ring 2 is made of a hard material having excellent wear resistance such as ceramic represented by SiC (silicon carbide), for example, and has a thread insertion hole through which a fishing line is inserted, and the fishing line slides on the inner peripheral surface. The fishing line is guided directly by moving.

  The guide frame 3 has a ring mounting hole 10 for mounting the guide ring 2. The guide ring 2 is inserted into the ring mounting hole 10 and fixed to the wall surface of the ring mounting hole 10 by adhesion. A plurality of convex portions 10a are formed on the wall surface of the ring mounting hole 10 in order to improve the holding force of the guide ring 2 and to secure the adhesive pool of the adhesive. The convex portion 10a is preferably formed at a constant angle. By forming a plurality of convex portions 10a on the wall surface of the ring mounting hole 10 at intervals in the circumferential direction, the outer peripheral surface of the guide ring 2 can be reliably held by the plurality of convex portions 10a. Further, by providing the convex portion 10a, the wall surface of the ring mounting hole 10 has an uneven shape in the circumferential direction, and a gap between the convex portions 10a can be used as an adhesion pool. Therefore, the guide ring 2 can be securely bonded to the guide frame 3.

  The guide frame 3 includes a cylindrical attachment portion 11 for attachment to the housing 4 and an annular ring holding portion 12 that extends radially outward from the front end portion of the attachment portion 11 and has a ring attachment hole 10. I have. The guide frame 3 is made of metal and integrally formed by forging, and is composed of one member. The attachment portion 11 and the ring holding portion 12 are not formed separately, but are integrally formed by forging and configured as one member. The material of the guide frame 3 may be various metals, and examples thereof include stainless steel and titanium (pure titanium or titanium alloy). In particular, titanium is advantageous for weight reduction and is suitable for a top guide.

  The attachment part 11 is cylindrical and the housing 4 is inserted inside thereof. That is, the attachment portion 11 has a collar insertion hole 13 into which the chassis 4 is inserted. The scissors insertion hole 13 may be any opening as long as the rear end is open, but in the present embodiment, the front end is also open. That is, the scissors insertion hole 13 may be a through hole or a non-through hole with a closed front end. Further, the flange insertion hole 13 has a long axial length with respect to its diameter. The front end of the casing 4 is inserted into the flange insertion hole 13 from the rear side and fixed by adhesion. Therefore, the center line 51 of the collar insertion hole 13 coincides with the center line of the chassis 4.

  The front end surface 11a of the attachment portion 11 may be a surface orthogonal to the center line 51 of the flange insertion hole 13, but in this embodiment, it is cut obliquely rearward from the upper side to the lower side as shown in FIG. The inclined surface is made. That is, as for the front end surface 11a of the attaching part 11, the part by the side opposite to a ring inclines back diagonally. The rear end surface 11 b of the attachment portion 11 is a vertical surface orthogonal to the center line 51 of the flange insertion hole 13. A chamfered portion such as an arc is formed at the rear end of the outer peripheral surface of the mounting portion 11.

  It should be noted that the rivet insertion hole 13 is also formed simultaneously by forging. However, after forming by forging, it is preferable that the wall surface of the heel insertion hole 13 is subjected to reamer processing as post-processing to increase the accuracy. That is, the wall surface of the eaves insertion hole 13 may be a forged surface or a cut surface. When the eaves insertion hole 13 is a through-hole as in this embodiment, it is easy to post-process the wall surface of the eaves insertion hole 13 and the dimensional accuracy can be increased. It is particularly suitable when the material is titanium. However, post-processing of the scissors insertion hole 13 is optional, and even if the forging is still in a forged state, the scissors insertion hole 13 is a through hole, so that the accuracy of forging is improved and the strength is ensured by forging. Can be thinned.

  Although the attachment part 11 is cylindrical, the rear part is not circular but is non-circular when viewed in cross section. In addition, a cross section is a cross section when it cut | disconnects in the direction orthogonal to the axial direction of the collar insertion hole 13 of the attaching part 11. FIG. D cut surface portions 20 and 21 are formed so as to be opposed to each other at two locations on the outer peripheral surface of the attachment portion 11, the position on the opposite ring side and the position on the ring side. As shown in FIG. 7, the D-cut surface portions 20 and 21 are formed at two locations out of the entire outer peripheral surface of the rear portion of the attachment portion 11, so that the D-cut surface portions 20 and 21 have other peripheral surface portions 22. It becomes thin compared with. That is, by forming the D-cut surface portions 20 and 21 on the outer peripheral surface of the rear portion of the attachment portion 11, the cross-sectional shape of the rear portion of the attachment portion 11 is not circular, but the rear portion is relatively thick. Thus, the thick portion and the thin portion that is relatively thin are provided. Further, the outer peripheral surface of the rear portion of the attachment portion 11 changes in the circumferential direction from the center line 51 of the heel insertion hole 13, and the center line 51 of the heel insertion hole 13 is changed in the D-cut surface portions 20 and 21. The distance from the center line 51 of the scissors insertion hole 13 is relatively large in the peripheral surface portion 22.

  Specifically, in the D-cut surface portion 20 on the opposite ring side, the distance from the center line 51 of the flange insertion hole 13 is the smallest in the circumferential center portion 20b (width direction center portion), and from there The distance gradually increases as the distance increases, and the distance becomes the largest at both ends 20c in the circumferential direction. Correspondingly, the D-cut surface portion 20 on the side opposite to the ring is the thinnest in the central portion 20b in the circumferential direction, and the thickness gradually increases as the distance from the circumferential portion increases. The portion 20c is thickest. Note that both end portions 20c in the circumferential direction of the D-cut surface portion 20 on the counter-ring side are boundary portions between the D-cut surface portion 20 and the peripheral surface portion 22 on the counter-ring side.

  Similarly, in the ring-side D-cut surface portion 21, the distance from the center line 51 of the collar insertion hole 13 is the smallest in the circumferential center portion 21 b (widthwise center portion), and from there in the circumferential direction. The distance gradually increases as the distance increases, and the distance becomes the largest at both ends 21c in the circumferential direction. The change in the circumferential direction of the wall thickness is the same as that on the non-ring side, and in the D-cut surface portion 21 on the ring side, the central portion 21b in the circumferential direction is the thinnest, and the wall thickness increases as the distance from the circumferential direction increases. The thickness gradually increases, and both end portions 21c in the circumferential direction are thickest. Note that both end portions 21 c in the circumferential direction of the ring-side D-cut surface portion 21 are boundary portions between the ring-side D-cut surface portion 21 and the peripheral surface portion 22.

  In addition, the distance from the center line 51 of the collar insertion hole 13 is the same in the center part 20b in the circumferential direction of the D-cut surface part 20 on the opposite ring side and the center part 21b in the circumferential direction of the D-cut surface part 21 on the ring side. . Accordingly, the thickness D1 at the center portion 20a in the circumferential direction of the D-cut surface portion 20 on the opposite ring side is the same as the thickness D1 at the center portion 21a in the circumferential direction of the D-cut surface portion 21 on the ring side.

  In the peripheral surface portion 22, the distance from the center line 51 of the flange insertion hole 13 may be constant, but in this embodiment, the ring side is slightly larger than the anti-ring side, The distance gradually increases from the ring toward the ring. That is, the distance from the center line 51 of the scissors insertion hole 13 gradually increases from the circumferential end portions 20c of the anti-ring side D-cut surface portion 20 toward the circumferential end portions 21c of the ring-side D cut surface portion 21. Of the entire circumference, the maximum value having the greatest distance is obtained at both end portions 21c in the circumferential direction of the D-cut surface portion 21 on the ring side. Although the wall thickness in the peripheral surface part 22 may be constant, the ring side is slightly thicker than the counter ring side.

  The anti-ring side D-cut surface portion 20 is formed over substantially the entire length of the anti-ring side portion of the mounting portion 11 as shown in FIGS. 3 and 5. In FIG. 3 and the like, a large number of dots are attached to the D-cut surface portions 20 and 21. The D-cut surface portion 20 on the side opposite to the ring is narrow, has a shape that is long along the axial direction of the mounting portion 11, and extends linearly along the axial direction of the mounting portion 11. Therefore, the D-cut surface portion 20 on the side opposite to the ring has a rectangular shape that is long in the axial direction of the mounting portion 11 when viewed from the front as shown in FIG. The D-cut surface portion 20 on the side opposite to the ring extends to the rear end portion of the attachment portion 11. Further, the D-cut surface portion 20 on the side opposite to the ring is a surface parallel to the axial direction of the mounting portion 11 as shown in FIG. 2 and is substantially flat as shown in FIG. 7, but slightly along the circumferential direction. Thus, a convex curved surface portion curved outward is formed. However, the curvature in the circumferential direction is smaller than the curvature of the other peripheral surface portion 22 of the outer peripheral surface of the mounting portion 11, and the absolute value of the curvature is very small. It has become.

  On the other hand, as shown in FIG. 4, the ring-side D-cut surface portion 21 is formed only at the rear portion of the attachment portion 11 and extends to the rear end portion of the attachment portion 11. The ring-side D-cut surface portion 21 has a long shape along the axial direction of the attachment portion 11, but the length along the axial direction of the attachment portion 11 is smaller than the D-cut surface portion 20 on the opposite ring side. short. Accordingly, the ring-side D-cut surface portion 21 has a rectangular shape that is slightly longer in the axial direction of the mounting portion 11 when viewed from the front as shown in FIG. In addition, the width which is the dimension in the left-right direction of the D-cut surface portion 21 on the ring side is wider than the width of the D-cut surface portion 20 on the opposite ring side. The anti-ring-side D-cut surface portion 20 and the ring-side D-cut surface portion 21 both extend from the rear end portion of the attachment portion 11 toward the front side, but the length from the rear end portion of the attachment portion 11 is The D-cut surface portion 20 on the side opposite to the ring is longer, and the D-cut surface portion 21 on the ring side is shorter. Further, the ring-side D-cut surface portion 21 is also a surface parallel to the axial direction of the mounting portion 11 in the same manner as the anti-ring-side D-cut surface portion 20, but as shown in FIG. 7, it is recessed inward along the circumferential direction. It is a concave curved surface portion that is curved.

  2 is a cross-sectional view taken along the line AA of FIG. 1, and the cross section is a cross section cut along a plane passing through the center line 50 of the ring mounting hole 10 and the center line 51 of the collar insertion hole 13. In FIG. 2, the formation region in the axial direction of the D-cut surface portion 20 on the opposite ring side is indicated by reference numeral 20a, and the formation region in the axial direction of the D-cut surface portion 21 on the ring side is indicated by reference numeral 21a. The thickness of the attachment portion 11 is thin as a whole. The thickness of the ring side portion of the entire circumference of the attachment portion 11 is the thickest at the front end portion (D3) and decreases toward the rear as a whole. Since the ring-side D-cut surface portion 21 is formed at the rear portion of the attachment portion 11, the length region 21a in which the ring-side D-cut surface portion 21 is formed is one step thinner than the front-side region. (D1). On the other hand, the thickness of the portion on the side opposite to the ring of the entire circumference of the mounting portion 11 is substantially constant (D1) over the entire length and is the same as the thickness of the portion on the ring side at the rear portion. This is thinner than the thickness D3 of the ring side portion.

  The ring holding portion 12 is formed so as to rise from the front end portion of the attachment portion 11 toward the radially outer side. The ring holding portion 12 rises at a right angle to the mounting portion 11, and accordingly, the center line of the guide ring 2, the center line 50 of the ring mounting hole 10, the center line of the housing 4, and the center of the rod insertion hole 13. The lines 51 are parallel to each other. The ring holding portion 12 is annular, and extends so as to circulate radially outward with the front end portion of the attachment portion 11 as a part of the entire circumference. Accordingly, a part of the entire circumference of the ring holding part 12 constitutes the front end part of the attachment part 11, and conversely, the front end part of the attachment part 11 constitutes a part of the whole circumference of the ring holding part 12. ing.

  A thick portion 14 that is thicker than the attachment portion 11 is provided at a boundary portion between the ring holding portion 12 and the attachment portion 11. As shown in FIG. 6, on the left and right sides of the base end portion on the mounting portion 11 side of the ring holding portion 12, the thickness in the radial direction is larger than the other portions (for example, the top portion, the thickness D 2) of the ring holding portion 12. A thick-walled portion 14 is formed.

  Further, a pair of left and right plate-shaped reinforcing wall portions 15 are formed so as to connect the rear surface of the ring holding portion 12 and the outer peripheral surface of the attachment portion 11 by a surface. Specifically, reinforcing wall portions 15 are formed between the left and right side portions of the rear surface of the ring holding portion 12 and the outer peripheral surface of the attachment portion 11. The reinforcing wall portion 15 is formed over the entire circumference of the ring holding portion 12 over an angular range from a location above the center line 50 of the ring mounting hole 10 to the attachment portion 11. The reinforcing wall portion 15 extends rearward from the rear surface of the ring holding portion 12, and the upper edge 15 a of the reinforcing wall portion 15 extends obliquely downward from the rear surface of the ring holding portion 12 toward the mounting portion 11. ing. The upper edge 15a of the reinforcing wall portion 15 is preferably rearward and downwardly inclined, and may be linear, but in this embodiment, it extends while drawing a curved line so as to draw a downward convex arc. Further, the reinforcing wall portion 15 is obtained by partially extending a region on the attachment portion 11 side of the annular ring holding portion 12 to the rear. In this way, the thick wall portion 14 and the reinforcing wall portion 15 are integrated to reinforce the boundary portion between the ring holding portion 12 and the mounting portion 11.

  The top guide provided with the guide frame 3 configured as described above is attached to the distal end portion of the rod body 4 of the tip. D-cut surface portions 20 and 21 are formed at two positions on the outer peripheral surface of the rear portion of the attachment portion 11 on the ring side and the counter-ring side so as to face each other by 180 degrees, and the attachment portion is formed by the two D-cut surface portions 20 and 21. 11 has a non-circular cross-sectional shape. Therefore, when the spikelet is stored inside the second basket when storing the basket, the rear part of the top guide mounting part 11 as shown in FIGS. Comes into contact with the moving guide 60 and stops. That is, the rear portion of the top guide attachment portion 11 does not enter the flange insertion hole 61 of the moving guide 60. More specifically, the portion of the peripheral surface portion 22 in the rear portion of the attachment portion 11 serves as a stopper and comes into contact with the movement guide 60, thereby preventing the top guide movement guide 60 from entering the flange insertion hole 61. Become. Therefore, when pulling out the tip rod from the second rod to use the swing rod next time, the moving guide 60 moves away smoothly from the top guide, and the moving guide 60 is moved quickly and smoothly to the rear side and fixed in place. can do. By forming the D-cut surface portions 20 and 21 in this way, it is possible to reliably prevent the top guide and the moving guide 60 from biting, and to prevent the adhesion between the top guide and the moving guide 60 and the occurrence of saltiness. it can. Further, although the attachment portion 11 is thin and light as a whole, the attachment portion 11 can be further reduced in weight by the D-cut surface portions 20 and 21.

  Moreover, since the D cut surface parts 20 and 21 are formed in two places in the outer peripheral surface of the rear part of the attachment part 11, it can further reduce in weight compared with the structure which is one place. Furthermore, the rear portion of the attachment portion 11 is not thickened over the entire circumference, but the D-cut surface portions 20 and 21 are formed at two locations on the ring side and the opposite ring side. The level difference between the end portion and the housing 4 can be reduced at the two locations, and the occurrence of yarn entanglement at the rear end portion of the attachment portion 11 can be prevented.

  Further, since the D-cut surface portion 20 is formed on the side opposite to the mounting portion 11, the center position of the top guide on the side opposite to the ring can be easily grasped. Therefore, when the top guide is attached to the tip of the housing 4, the orientation of the housing 4 and the top guide can be easily aligned by visual observation. Further, since the D-cut surface portion 21 is also formed on the ring side of the attachment portion 11, the phase alignment in the circumferential direction between the top guide and the casing 4 by visual observation becomes even easier. Furthermore, when the top guide is set on the jig, the circumferential positioning of the top guide can be easily performed by using the two D-cut surface portions 20 and 21.

  Particularly, since the D-cut surface portion 20 on the side opposite to the ring is narrow and extends linearly along the axial direction of the mounting portion 11, the orientation of the housing 4 and the top guide can be easily aligned by visual observation. Further, since the D-cut surface portion 20 on the opposite ring side can be used as a main mark and the D-cut surface portion 21 on the ring side can be used as a sub mark, the circumferential positions of the top guide and the housing 4 can be easily aligned. be able to.
