Description

Single bearing reel

  The present invention relates to a fishing reel, and more particularly to a single bearing reel that can be mounted on a fishing rod.

  A single bearing reel in which a spool shaft is cantilevered on a reel body includes a reel body, a spool shaft that is cantilevered on the reel body, and a spool that is rotatably mounted on the spool shaft. The reel body has a disk-shaped frame and a hook mounting portion fixed to the frame.

  In such a single-bearing reel, in order to facilitate the operation of braking the frame by bringing the hand into contact with the spool, a frame having an outer diameter smaller than the outer diameter of the spool is known (for example, patents). Reference 1).

  In the conventional single bearing reel, the saddle mounting part is fixed to the center of the frame, the arm part extending in the radial direction from the fixed part, and the arm part is bent from the arm part and is mounted radially outside the spool. And a leg portion. The spool includes a bobbin portion having a plurality of rod-like members arranged at intervals in the circumferential direction, and a pair of flange portions arranged at both ends of the bobbin portion. The outer surface of the flange portion is formed in a recessed shape, and the frame enters the recessed portion. Therefore, the outer diameter of the frame is smaller than the outer diameter of the flange portion. Further, the frame is disposed on the inner side in the axial direction from the flange portion, and does not protrude from the flange portion into the recessed portion of the flange portion. Thereby, even if the fishing line wound around the bobbin part falls from the flange part, it does not come into contact with the frame, and it is difficult for the fishing line to enter the gap between the flange part and the frame.

Japanese Utility Model No. 363365

  In the conventional configuration, even if the fishing line falls from the flange portion, it is possible to prevent the thread from being caught in the gap between the frame and the flange portion. However, the fishing line that has fallen from the flange portion moves rapidly to the gap between the arm portion of the rod mounting portion and the frame, and there is a risk that the bite that enters the gap tightly occurs.

  An object of the present invention is to make it difficult for a single-bearing reel having a frame having a smaller diameter than a flange portion to bite between a frame and a rod mounting portion even if a fishing line falls from the flange portion.

  A single bearing reel according to a first aspect of the present invention is a reel that can be mounted on a fishing rod and can feed a fishing line forward, and includes a spool, a spool shaft, and a reel body. The spool includes a bobbin body for bobbin winding, a first flange provided at one end of the bobbin body and having a larger diameter than the bobbin body, and a second provided at the other end of the bobbin body and having a larger diameter than the bobbin body. And a flange portion. The spool shaft rotatably supports the spool. The reel main body includes a circular frame that is arranged to face the first flange portion and supports the spool shaft, and a rod mounting portion that is fixed to the frame and on which a fishing rod can be mounted. The outer diameter of the frame is smaller than the outer diameter of the first flange portion. The circular frame has an outer surface, an outer peripheral surface, and a thread guide surface. The outer side surface is disposed on the outer side in the axial direction of the spool shaft from the first flange portion. At least a part of the outer peripheral surface is disposed on the inner side in the axial direction from the first flange portion. The yarn guide surface gradually decreases in diameter from the outer peripheral surface toward the outer surface.

  In this single bearing reel, the outer diameter of the frame is smaller than the first flange portion of the spool. The frame includes an outer peripheral surface at least a part of which is disposed on the inner side in the axial direction from the first flange portion, an outer surface disposed on the outer side in the axial direction, and a yarn guide surface that gradually decreases in diameter from the outer peripheral surface toward the outer surface. And have. For this reason, when the fishing line wound around the spool falls from the first flange portion, the fishing line comes into contact with the outer peripheral surface or the line guiding surface of the frame, and is further guided to the outer surface while being in contact with the line guiding surface. Here, even if the fishing line falls from the first flange portion, the dropped fishing line is guided to the outer surface while being in contact with the outer peripheral surface of the frame or the yarn guide surface and further in contact with the yarn guide surface. For this reason, the fishing line is decelerated by these contacts and moves between the rod mounting portion and the frame. Therefore, even if the fishing line falls from the first flange portion, it is difficult to bite between the frame and the rod mounting portion.

  A single-bearing reel according to a second aspect of the present invention is the reel according to the first aspect, wherein the first flange portion has at least one first annular protrusion protruding in the axial direction at least on the outer peripheral portion, and the frame is at least on the outer peripheral surface. At least one second annular protrusion is formed to protrude toward the first flange portion so as to overlap the first annular protrusion and the axial direction of the spool shaft.

  In this case, even if the fishing line wound around the spool falls from the first flange portion, the fishing line comes into contact with the second annular protrusion or the thread guide surface of the frame that overlaps the first annular protrusion of the first flange portion in the axial direction. Guided from the surface to the outer surface. For this reason, even if the diameter of the first flange portion is larger than that of the frame, it is difficult for the fishing line to enter the spool through the gap between the frame and the first flange portion. In addition, since the second annular protrusion protruding toward the first flange portion is disposed so as to overlap the first annular protrusion in the axial direction, the fishing line is surely brought into contact with the second annular protrusion or the thread guide surface and is decelerated. For this reason, the biting between the frame and the hook mounting portion can be further reduced.

  The single-bearing reel according to a third aspect of the present invention is the reel according to the second aspect, wherein two first annular protrusions are provided at an interval in the radial direction of the first flange portion with the second annular protrusion interposed therebetween. In this case, the number of axially overlapping portions between the spool and the frame increases, so that it is possible to further prevent the thread from entering the spool.

  A single-bearing reel according to a fourth aspect of the present invention is the reel according to the second or third aspect, wherein the second annular protrusion is continuous with the yarn guide surface on the axially outer side from the first flange portion. In this case, since the second annular protrusion is continuous with the line guide surface on the axially outer side from the first flange part, the possibility that the fishing line falling from the first flange part falls on the second annular protrusion increases, and the line guide The fishing line is surely decelerated before being guided to the surface.

  The single-bearing reel according to a fifth aspect of the present invention is the reel according to the fourth aspect, wherein the outer peripheral surface on which the second annular protrusion is formed is a circumferential surface disposed from the inner side to the outer side in the axial direction of the first annular protrusion, The guide surface is formed from the outer peripheral surface toward the outer surface. In this case, since the outer peripheral surface constituted by the circumferential surface protrudes outward in the axial direction from the first flange portion, there is a high possibility that the fishing line dropped from the first flange portion will fall on the outer peripheral surface where the diameter is not reduced. Further, it is surely decelerated before being guided by the yarn guide surface.

  The single-bearing reel according to a sixth aspect of the present invention is the reel according to any one of the first to fifth aspects, wherein the saddle mounting portion has a fixed portion, an arm portion, and a mounting leg portion. The fixing part is fixed to the frame. The arm portion extends from the fixed portion to the outside of the frame and then bends to be arranged radially outward of the spool. The mounting leg portion is disposed at the front end of the arm portion in the front-rear direction and can be mounted on the fishing rod. The length of the arm portion in the front-rear direction is 5 mm or more and 20 mm or less, and the mounting leg portion is arranged so that a finger of a hand having a fishing rod can be inserted between the arm portion and the frame.

  In this case, since the length of the arm portion in the front-rear direction, that is, the width is narrow, and a finger can be inserted between the frame and the mounting leg portion, the arm portion is, for example, an index finger like a spinning reel. The single-bearing reel can be held by gripping the mounting leg together with the fishing rod by sandwiching it with fingers such as the middle finger.

  A single-bearing reel according to a seventh aspect is the reel according to the sixth aspect, wherein the fixing portion is fixed to the frame such that a gap between the mounting leg portion and the frame can be changed. In this case, the mounting leg can be separated from the frame and a finger can be inserted between the frame to hold the reel, and the mounting leg can be moved closer to the frame to facilitate the brake operation with the finger. it can.

  A single-bearing reel according to an eighth aspect of the present invention is the reel according to the seventh aspect, wherein the frame protrudes in a circular shape centering on a circular frame main body and a position eccentric to the spool shaft from the outer surface of the frame main body. A fixed convex portion provided, and the fixed portion has an inner peripheral surface that is fitted to the outer peripheral surface of the fixed convex portion.

  In this case, by fixing the fixing portion to the frame at any one of a plurality of fixing positions in the circumferential direction of the fixing convex portion that is eccentric with respect to the spool shaft, the distance between the spool shaft and the hook mounting portion can be easily achieved. Can change.

  According to the present invention, even if the fishing line falls from the first flange portion, the dropped fishing line is guided to the outer surface while being in contact with the outer peripheral surface of the frame or the yarn guide surface and further in contact with the yarn guide surface. For this reason, the fishing line is decelerated by these contacts and moves between the rod mounting portion and the frame. Therefore, even if the fishing line falls from the first flange portion, it is difficult to bite between the frame and the rod mounting portion.

<First Embodiment>
1, 2, and 3, the single-bearing reel according to the first embodiment of the present invention includes a reel body 1, a spool shaft 2 that is cantilevered on the reel body 1, and is rotatable with respect to the spool shaft 2. And a spool 3 around which a fishing line is wound.

<Structure of reel body>
The reel body 1 includes a circular frame 10 that supports the spool shaft 2 and a rod mounting portion 12 for mounting a fishing rod RD that is detachably fixed to the frame 10. The frame 10 has a support hole 10a in which the spool shaft 2 is cantilevered. The frame 10 includes, for example, a disk-shaped frame main body 13 made of metal such as an aluminum alloy, and a fixed convex portion 14 made of metal such as aluminum alloy or made of synthetic resin provided on the frame main body 13. ing.

The frame main body 13 is an edged disk-shaped member formed by pressing a thin aluminum alloy plate. The frame body 13 is a circular member having a smaller diameter than the spool 3. The frame body 13 has an outer surface 10d that is disposed on the axially outer side (the right side in FIG. 3) of the spool shaft 2 with respect to a later-described first annular protrusion 36c of the spool 3. As shown in FIG. 4, the outer peripheral portion of the frame body 13 is curved so as to protrude toward the first first flange portion 36 a side of the spool 3. The frame body 13 has a second annular protrusion 10e formed on the outer peripheral surface 10g at the tip so as to protrude toward the first flange portion 36a. The outer peripheral surface 10g on which the second annular protrusion 10e is formed is a circumferential surface disposed from the outer side (right side in FIG. 4) to the inner side (left side in FIG. 4) of the first annular protrusion 36c. That is, in the first embodiment, the base end of the outer peripheral surface 10g, which is a circumferential surface, is disposed on the axially outer side from the front end of the first annular protrusion 36c described later, and the front end of the outer peripheral surface 10g is the first annular protrusion 36c. It is arrange | positioned in the axial direction inner side from the front-end | tip of. The surface that curves toward the outer surface 10d that is connected to the base end of the outer peripheral surface 10g of the frame main body 13 and is arranged outside the first annular protrusion 36c and gradually reduces the diameter of the fishing line that has fallen from the spool 3 A yarn guide surface 10f for guiding to 10d is configured. In the first embodiment, the yarn guide surface 10f is formed of a fillet-shaped curved surface 10h having a circular arc shape in cross section and a tapered surface 10i having a linear shape in cross section. The reduced diameter ratio of the curved surface 10h is gradually increased. Further, the taper surface 10i has the same diameter reduction ratio. The taper surface 10i is in contact with the inner side surface 22a of the arm portion 22 of the saddle mounting portion 12 at substantially the same radial position as the position where the first annular protrusion 36c on the inner peripheral side is formed. The diameter reduction ratio of the yarn guide surface 10f may be gradually decreased, gradually increased, or constant. Moreover, you may combine them.

By forming the yarn guide surface 10f having such a configuration, a finger of a hand having a fishing rod RD can be placed on the yarn guide surface 10f. For this reason, the brake operation by the finger can be performed only by sliding the finger placed on the yarn guide surface 10f on the first flange portion 36a, and the finger slid on the first flange portion 36a is simply returned to the yarn guide surface 10f by the finger. The brake operation can be released. For this reason, a brake operation and a release operation with a finger can be performed quickly and stably. If the outer surface 10d of the frame body 13 is on the inner side in the axial direction of the first annular protrusion 36c and there is no thread guide surface 10f protruding from the first flange portion 36a, there is no place for placing a finger. For this reason, when releasing the brake, the finger must be lifted away from the first flange portion, and it is difficult to perform the brake operation and the release operation with the finger quickly and stably.

  As shown in FIG. 3, a mounting hole 13 a in which the fixed convex portion 14 is mounted is formed in the shaft core C <b> 2 eccentric from the spool shaft core C <b> 1 of the frame body 13. A plurality of (for example, eight) passage holes 13b formed at intervals in the circumferential direction are formed on the outer side in the radial direction of the mounting hole 13a of the frame body 13.

  The fixed convex portion 14 is disposed on the inner side surface 13c of the frame main body 13, and has a mounting portion 14b having a larger diameter than the mounting hole 13a and a circular shape from the outer surface 10d of the frame main body 13 through the mounting hole 13a from the mounting portion 14b. And a protruding portion 14c that protrudes. A boss portion 10 b in which the support hole 10 a described above is formed along the shaft core C <b> 1 located at the center of the frame 10 is formed on the fixed convex portion 14 so as to protrude toward the tip end side of the spool shaft 2. In the first embodiment, the fixed convex portion 14 is formed separately from the frame main body 13, but may be formed integrally with the frame main body 13. A circular opening 14d centering on the axis C2 is formed at the tip of the protrusion 14c. The opening 14d is formed for screwing the fixing bolt 26 and for weight reduction. The opening 14d is closed by a name plate (not shown).

  As shown in FIGS. 2 and 3, the mounting portion 14 b of the fixed convex portion 14 has a plurality of female screw portions 18 that are arranged at intervals in the circumferential direction outward in the radial direction of the protruding portion 14 c. The female screw portion 18 is a screw hole into which a bolt member 16 for fixing the heel mounting portion 12 to the frame 10 is screwed. The female screw portion 18 is formed along the axial direction. The bolt member 16 is, for example, a countersunk head bolt. In the first embodiment, the saddle mounting portion 12 is fixed by four bolt members 16. The bolt member 16 fixes the heel mounting portion 12 to the frame 10 and also fixes the frame body 13 sandwiched between the heel mounting portion 12 and the mounting portion 14 b to the fixed convex portion 14.

  The eaves mounting portion 12 is a member made of a metal such as an aluminum alloy or a synthetic resin such as a polyamide resin impregnated with short glass fibers. The scissors mounting portion 12 has a fixing portion 20 that can be fixed to the frame 10 at any of a plurality of fixing positions at different distances from the spool shaft 2, an arm portion 22, and a mounting leg portion 24. The fixed portion 20 has a ring shape having an inner peripheral surface 20 b that fits with the outer peripheral surface 14 a of the fixed convex portion 14. The fixing part 20 has a plurality of fixing holes 20a arranged at intervals in the circumferential direction. The fixing hole 20 a is formed along the axial direction of the spool shaft 2 so as to be able to face the female screw portion 18.

  It is preferable that the number of the internal thread portions 18 is larger than the number of the fixing holes 20a. This is because when the number of female screw portions is reduced and the number of fixing holes is increased, fixing holes that are not used for fixing are exposed on the surface of the fixing portion. In the first embodiment, the number of the female screw portions 18 is eight, and the number of the fixing holes 20a is four. As described above, when the female screw portion 18 is larger than the fixing hole 20a, the unused female screw portion 18 is covered with the fixing portion 20 and is not exposed to the outside. In the first embodiment, as shown in FIG. 5, the hook mounting portion 12 can be fixed to the frame 10 at any one of eight circumferential fixing positions F <b> 1-F <b> 8 using four bolt members 16.

  As shown in FIGS. 2 and 3, the arm portion 22 is integrally formed with the fixed portion 20. The arm portion 22 extends from the fixed portion 20 to the outer side in the radial direction of the frame 10, and then bends to be arranged at the outer side in the radial direction of the spool 3. The length L of the arm part 22 in the front-rear direction (left-right direction in FIG. 2) is 5 mm or more and 20 mm or less, preferably 5 mm or more and 15 mm or less. As described above, when the length (width) L in the front-rear direction of the arm portion 22 is shortened, the single bearing reel can be held with the arm portion 22 sandwiched between two fingers having a fishing rod RD. The arm portion 22 gradually increases in thickness from the connecting portion with the fixed portion 20, and has the maximum thickness on the near side of the curved portion.

  The mounting leg portion 24 is formed integrally with the arm portion 22. The mounting leg portion 24 is disposed at the front end of the arm portion 22 in the front-rear direction and can be mounted on the fishing rod RD. Therefore, the mounting leg 24 has a mounting surface 24a having a circular arc shape in cross section that can contact the fishing rod RD on the upper surface.

  In the reel main body 1 having such a configuration, the hook mounting portion 12 that fits to the outer peripheral surface of the fixed convex portion 14 that protrudes in a circular shape with the center C2 as the position eccentric from the axis C1 of the spool shaft 2 is fixed to the frame 10. doing. For this reason, as shown in FIG. 5, distances D1-D8 between the mounting surface 24a of the saddle mounting portion 12 and the axis C1 of the spool shaft 2 at eight fixed positions F1-F8 in the circumferential direction of the saddle mounting portion 12. Different. Specifically, the distance D1-D5 gradually increases from the fixed position F1 toward the fixed position F5, and the distance D5-D1 decreases gradually from the fixed position F5 toward the fixed position F1. For this reason, by fixing the heel mounting portion 12 to the frame 10 at any one of the eight fixing positions F1-F8, the distance from the heel mounting portion 12 spool shaft 2, that is, the radial position of the heel mounting portion 12 is determined. Can be changed. At the same time, the distances S1-S8 between the axial center C1 of the spool shaft 2 and the center position C3 in the front-rear direction of the rod mounting portion 12 are different at the eight fixed positions F1-F8. Therefore, the front-rear position of the collar mounting portion 12 with respect to the spool shaft can also be changed. The distance S1 and the distance S5 are “0” and are not shown in FIG. Therefore, the heel mounting portion 12 can be fixed to any of the eight fixed positions F1-F8 in which the combination of the front-rear position and the radial position is different.

<Configuration of spool shaft>
As shown in FIG. 3 , the small diameter portion 2 a at the base end of the spool shaft 2 is fitted in a support hole 10 a formed in the fixed convex portion 14 of the frame 10. The spool shaft 2 is fixed to the fixed convex portion 14 of the frame 10 by a fixing bolt 26 screwed into the base end surface. At the tip of the spool shaft 2, a first annular groove 2b and a head 2c having a diameter larger than that of the first annular groove 2b and a tapered tip are formed. A bush mounting portion 2d to which the bush 21 is mounted is formed adjacent to the first annular groove 2b. The proximal end side of the bush mounting portion 2d is formed to have a larger diameter than the bush mounting portion 2d, and a second annular groove 2e is formed there.

<Spool configuration>
As shown in FIG. 3 , the spool 3 can be attached / detached to / from the spool shaft 2 by a one-touch attachment / detachment mechanism 6. The spool 3 includes a bobbin trunk 35 that is rotatably supported by the spool shaft 2, and a first flange portion 36a and a second flange portion 36b, which are integrally formed. These may be constituted separately.

  The bobbin trunk 35 includes a cylindrical bobbin 35a on which an fishing line can be wound around an outer peripheral surface, a support tube 37 that is rotatably supported by the spool shaft 2 on the inner peripheral side of the bobbin 35a, and a bobbin 35a. And a disk-shaped connecting portion 38 that connects the support cylinder portion 37 to each other. The support cylinder portion 37 is a cylindrical member having a through-hole 37 a through which the spool shaft 2 can pass, and the distal end side is closed by a lid member 31 constituting the one-touch attachment / detachment mechanism 6. A first bearing 40 and a second bearing 42 for rotatably supporting the spool 3 on the spool shaft 2 are mounted between the through hole 37a and the spool shaft 2 with an interval in the axial direction. The second bearing 42 is positioned by a retaining member 43 attached to the second annular groove 2e.

  The connecting portion 38 has a disk shape that connects the bobbin portion 35 a and the support tube portion 37. A handle handle 44 for rotating the spool 3 and a balance weight 46 arranged at an interval of 180 degrees in the circumferential direction of the handle handle 44 are attached to the connecting portion 38.

  The first flange portion 36 a is a disc-shaped member formed integrally with the bobbin trunk 35 at one end of the bobbin trunk 35. The first flange portion 36 a is formed to face the frame 10 of the reel body 1. The outer diameter of the first flange portion 36 a is larger than the outer diameter of the frame 10.

  As shown in FIG. 4, two first annular protrusions 36 c are formed on the outer peripheral surface of the first flange portion 36 a so as to protrude outward in the axial direction toward the frame 10 with a gap in the radial direction. ing. The first annular protrusion 36c on the outer peripheral side is disposed radially outward of the second annular protrusion 10e at the outer peripheral portion, and protrudes outward in the axial direction, that is, toward the frame 10 so as to overlap the axial direction of the spool shaft 2. . The first annular protrusion 36c on the inner peripheral side is disposed on the inner peripheral side of the second annular protrusion 10e, and protrudes so as to overlap the second annular protrusion 10e in the axial direction.

  As shown in FIG. 3, the second flange portion 36 b is formed integrally with the other end portion of the bobbin trunk 35 so as to cover the open portion of the reel body 1. In the first embodiment, the second flange portion 36b is formed to have the same diameter as the first flange portion 36a. However, the second flange portion 36b may have a diameter different from that of the first flange portion 36a. For example, the second flange portion 36b may have a smaller diameter than the first flange portion 36a.

<Configuration of one-touch attachment / detachment mechanism>
As shown in FIG. 3 , the one-touch attachment / detachment mechanism 6 includes a spring member 30 made of an elastic wire that is locked in the first annular groove 2 b of the spool shaft 2, and a support cylinder portion 37 for preventing the spring member 30 from coming off. It has a lid member 31 screwed and fixed to the tip, a push button 32 attached to the lid member 31 so as to be axially movable, and a bush 21 for disposing the spring member 30 between the lid member 31. Yes. The bush 21 regulates the circumferential position of the push button 32.

  The spring member 30 is a spring for mounting the spool 3 on the spool shaft 2 so as not to move in the axial direction. The spring member 30 also has a function of urging the push button 32 forward (leftward in FIG. 3). The spring member 30 is formed by bending an elastic wire, and generates a forward biasing force when deformed.

  In the one-touch attaching / detaching mechanism 6 having such a configuration, when the push button 32 is pressed, the spring member 30 is detached from the first annular groove 2b and the spool 3 can be detached from the spool shaft 2. When the spool 3 is mounted on the spool shaft 2, the spring member 30 spreads and then is locked in the first annular groove 2 b and mounted on the spool shaft 2 so as not to come off.

  Next, a method for fixing the heel mounting portion 12 will be described.

  For example, a person with short fingers, such as a woman, attaches the heel mounting part 12 to the frame 10 at the fixed position F1 in FIG. Then, the index finger or middle finger of the hand holding the fishing rod RD is close to the spool 3, and it becomes easy to perform a brake operation with the finger on the spool 3. A person with a long finger uses, for example, one of the fixed positions F2 to F8. At the fixed position F <b> 2-F <b> 4, the shaft center C <b> 1 of the spool shaft 2 moves forward from the center C <b> 3 of the saddle mounting portion 12. Further, at the fixed position F <b> 6-F <b> 8, the shaft core C <b> 1 of the spool shaft 2 moves rearward from the center C <b> 3 of the rod mounting part 12.

  On the other hand, the single-bearing reel can be held with the arm portion 22 of the saddle mounting portion 12 sandwiched like a spinning reel. In this case, it is preferable to use the fixed positions F3-F7. Then, the clearance gap between the mounting leg part 24 and the flame | frame 10 becomes large, and a finger can be passed between them. For this reason, for example, the arm portion 22 is bent between the index finger and the middle finger, and the mounting leg portion 24 can be gripped together with the fishing rod RD. Even in such a case, it becomes easier to perform a brake operation with the finger by changing the fixed position according to the length of the finger.

  If fishing line falls from the 1st flange part 36a to the frame main body 13 side during fishing, the dropped fishing line will contact the outer peripheral surface 10g of the 2nd annular protrusion 10e. As a result, the fishing line decelerates, moves in contact with the line guide surface 10f, and falls between the inner side surface 22a of the arm 22 of the rod mounting portion 12 and the line guide surface 10f. However, since it reaches the outer peripheral surface 10g and the yarn guide surface 10f and decelerates until it reaches, it becomes difficult to bite between the inner side surface 22a and the yarn guide surface 10f.

Second Embodiment
In the second embodiment, although the shape is different from that of the first embodiment, parts having the same function are indicated by adding a reference numeral obtained by adding 100 to the reference numeral of the first embodiment. Further, description of the parts having the same configuration as in the first embodiment is omitted.

  As shown in FIGS. 6 and 7, the single-bearing reel according to the second embodiment is different from the first embodiment in the fixed shape of the flange mounting portion 112 of the frame 110 of the reel body 101. Further, the shapes of the second annular protrusion 110e and the yarn guide surface 110f are different from those of the first embodiment.

  In the second embodiment, the frame body 113 and the fixed projection 114 are integrally formed. Specifically, a plurality of female screw portions 118 are arranged radially on the outer peripheral surface 114a of the fixed convex portion 114 along the radial direction. Therefore, the axial dimension of the fixed convex portion 114 is slightly large. In addition, a plurality of fixing holes 120 a are formed along the radial direction of the fixing portion 120 having an inner peripheral surface 120 b that fits to the outer peripheral surface 114 a of the fixing convex portion 114. In the second embodiment, the fixed portion 120 has a slightly larger axial dimension than the first embodiment, but the radial dimension is smaller than that of the first embodiment. In the second embodiment, as an example, the number of fixing holes 120a is three, and the number of female screw portions 118 is twelve. Therefore, in the second embodiment, the heel mounting portion 112 is fixed to the frame 110 with the three bolt members 116. Further, the number of fixed positions is 12 in the second embodiment.

In this case, to form the female screw portion 118 on the outer peripheral surface 114a of the securing boss 114, since the arranged along the radial direction to the stationary part 12 0 of fixing holes 120a, the axial direction of the fixing protrusion 114 and the fixing portion 120 The dimension of becomes larger. However, an increase in the overall mass can be suppressed by reducing the dimensions in the radial direction.

  As shown in FIG. 8, two second annular protrusions 110e are formed on the radially inner peripheral side by the outer peripheral part and the outer peripheral part of the frame body 113 with the first annular protrusion 36c on the inner peripheral side being sandwiched therebetween. The second annular protrusion 110e on the inner peripheral side protrudes to the same axial position as the second annular protrusion 110e on the outer peripheral side. However, the protruding position only needs to overlap the first annular protrusion 36c on the inner peripheral side in the axial direction, and need not be the same. For example, it may not protrude from the second annular protrusion 110e on the outer peripheral side.

  In addition, the base end of the outer peripheral surface 110g formed on the second annular protrusion 110e on the outer peripheral side is located on the inner side in the axial direction (left side in FIG. 8) from the distal end portion of the first annular protrusion 36c on the outer peripheral side. Accordingly, the yarn guide surface 110f is gradually reduced in diameter from the inner end in the axial direction toward the outer surface 110d from the tip end portion of the first flange portion 36a. In this embodiment, the yarn guide surface 110f is composed of two curved surfaces having a circular arc shape in cross section. The first curved surface 110h is a fillet-shaped curved surface having a circular arc shape in cross section, and is connected to the base end of the outer peripheral surface 110g, and the diameter reduction ratio is gradually increased. The second curved surface 110i is connected to the first curved surface 110h, and the reduced diameter ratio is gradually reduced. The second curved surface 110 i is in contact with the inner side surface 122 a of the arm portion 22 of the heel mounting portion 112.

  As described above, when the base end of the first flange portion 36a is set inward in the axial direction of the line guide surface 110f, the fishing line dropped from the first flange portion 36a always comes into contact with the line guide surface 110f. Accordingly, it is possible to further prevent the thread from entering the spool 3. Further, since the line guiding surface 110f has the second curved surface 110i having a reduced diameter reduction ratio, the fishing line that has fallen from the first flange portion 36a further decelerates, and the inner side surface 122a of the arm portion 122 of the rod mounting portion 112. And the yarn guide surface 110f are more difficult to bite.

<Features>
(A) The single-bearing reel is a reel that is mounted on a fishing rod and can feed out a fishing line forward. The single bearing reel includes a spool 3 for spooling, a spool shaft 2, and a reel body 1 (101). The spool 3 includes a bobbin trunk 35 for bobbin winding, a first flange portion 36 a having a diameter larger than that of the bobbin trunk 35, and a bobbin trunk provided at the other end of the bobbin trunk 35. 35 and a second flange portion 36b having a diameter larger than 35. The spool shaft 2 rotatably supports the spool 3. The reel body 1 (101) has a circular frame 10 (110) that is disposed opposite to the first flange portion 36a and supports the spool shaft 2, and a rod mounting that is fixed to the frame 10 (110) and can be mounted with a fishing rod RD. Part 12 (112). The outer diameter of the frame 10 (110) is smaller than the outer diameter of the first flange portion 36a. The circular frame 10 (110) has an outer surface 10d (110d), an outer peripheral surface 10g (110g), and a yarn guide surface 10f (110f). The outer side surface 10d (110d) is disposed on the outer side in the axial direction of the spool shaft 2 from the first flange portion 36a. At least a part of the outer peripheral surface 10g (110g) is disposed on the inner side in the axial direction from the first flange portion 36a. The yarn guide surface 10f (110f) is gradually reduced in diameter from the outer peripheral surface 10g (110g) toward the outer surface 10d (110d).

  In this single-bearing reel, the outer diameter of the frame 10 (110) is smaller than the first flange portion 36a of the spool 3. The frame 10 (110) includes an outer peripheral surface 10g (110g) at least partly disposed on the inner side in the axial direction from the first flange portion 36a, an outer surface 10d (110d) disposed on the outer side in the axial direction, and an outer peripheral surface 10g. A thread guide surface 10f (110f) that gradually decreases in diameter from (110g) toward the outer surface 10d (110d). Therefore, when the fishing line wound around the spool 3 falls from the first flange portion 36a, the fishing line comes into contact with the outer peripheral surface 10g or the line guide surface 110f of the frame 10 (110), and further contacts the line guide surface 10f (110f). While being guided to the outer surface 10d (110d). Here, even if the fishing line falls from the first flange portion 36a, the dropped fishing line comes into contact with the outer peripheral surface 10g or the yarn guide surface 110f of the frame 10 (110) and further contacts with the yarn guide surface 10f (110f). It is guided to the side surface 10d (110d). Therefore, the fishing line is decelerated by these contacts and moves between the rod mounting portion 12 (112) and the frame 10 (110). Therefore, even if the fishing line falls from the first flange portion 36a, it becomes difficult to bite between the frame 10 (110) and the rod mounting portion 12 (112).

  (B) In the single-bearing reel, the first flange portion 36a has at least one first annular protrusion 36c protruding in the axial direction at least on the outer peripheral portion, and the frame 10 (110) has at least the outer peripheral surface 10g (110g). At least one second annular protrusion 10e (110e) formed to protrude toward the first flange portion 36a so as to overlap the first annular protrusion 36c and the axial direction of the spool shaft 2 is provided.

  In this case, even if the fishing line wound around the spool 3 falls from the first flange portion 36a, the second annular projection 10e (of the frame 10 (110)) that overlaps the first annular projection 36c of the first flange portion 36a in the axial direction. 110e) or the yarn guide surface 10f (110f), and is guided from the yarn guide surface 10f (110f) to the outer surface 11d (110d). For this reason, even if the diameter of the first flange portion 36a is larger than that of the frame 10 (110), it is difficult for the fishing line to enter the spool 3 through the gap between the frame 10 (110) and the first flange portion 36a. . In addition, since the second annular protrusion 10e (110e) protruding toward the first flange portion 36a is disposed so as to overlap the first annular protrusion 36c in the axial direction, the second annular protrusion 10e (110e) or the thread guide surface 10f. The fishing line is reliably brought into contact with (110f) and decelerated. For this reason, the biting between the frame 10 (110) and the heel mounting portion 12 (112) can be further reduced.

  (C) In the single-bearing reel, two first annular protrusions 36c are provided at an interval in the radial direction of the first flange portion 36a with the second annular protrusion 10e (110e) interposed therebetween. In this case, the number of axially overlapping portions between the spool 3 and the frame 10 (110) increases, so that it is possible to further prevent the thread from getting into the spool 3 from entering.

  (D) In the single-bearing reel, the second annular protrusion 10e is continuous with the yarn guide surface 10f on the axially outer side from the first flange portion 36a. In this case, since the second annular protrusion 10e is continuous with the line guide surface 10f on the axially outer side from the first flange part 36a, the fishing line falling from the first flange part 36a may fall on the second annular protrusion 10e. The fishing line is surely decelerated until it becomes higher and guided by the line guide surface 10f.

  (E) In the single-bearing reel, the outer peripheral surface 10g on which the second annular protrusion 10e is formed is a circumferential surface disposed from the inner side to the outer side in the axial direction of the first annular protrusion 36c, and the yarn guide surface 10f is the outer peripheral surface. It is formed from the surface 10g toward the outer surface 10d. In this case, since the base end of the outer peripheral surface 10g formed by the circumferential surface protrudes axially outward from the first flange portion 36a, the outer peripheral surface 10g where the fishing line that has fallen from the first flange portion 36a does not reduce the diameter. And the vehicle is surely decelerated before being guided by the yarn guide surface 10f.

  (F) In the single-bearing reel, the saddle mounting portion 12 (112) has a fixed portion 20 (120), an arm portion 22 (122), and a mounting leg portion 24. The fixing unit 20 (120) is fixed to the frame 10 (110). The arm portion 22 (122) extends from the fixed portion 20 (120) to the outside of the frame 10 (110) and then bends to be arranged radially outward of the spool 3. The mounting leg portion 24 is disposed at the front end of the arm portion 22 (122) in the front-rear direction and can be mounted on the fishing rod RD. The length of the arm portion 22 (122) in the front-rear direction is 5 mm or more and 20 mm or less, and the mounting leg portion 24 is arranged so that a finger of a hand having a fishing rod RD can be inserted between the mounting leg portion 24 and the frame 10 (110). .

  In this case, the length of the arm portion 22 (122) in the front-rear direction, that is, the width is narrow, and a finger can be inserted between the frame 10 (110) and the mounting leg portion 24. In addition, the arm portion 22 (122) can be held between fingers such as an index finger and a middle finger, for example, and the mounting leg portion 24 can be held together with the fishing rod RD to hold the single bearing reel.

  (G) In the single bearing reel, the fixing portion 20 (120) is fixed to the frame 10 (110) so that the gap between the mounting leg portion 24 and the frame 10 (110) can be changed. In this case, the mounting leg 24 can be separated from the frame 10 (110) and a finger can be inserted between the mounting leg 24 and the frame 10 (110) to hold the single-bearing reel, and the mounting leg 24 can be attached to the frame 10 (110). It is also possible to make it easier to perform a brake operation with a finger close to (110).

  (H) In the single-bearing reel, the frame 10 (110) is a position 8 that is eccentric with respect to the spool shaft 2 from the circular frame body 13 (113) and the outer surface 10d (110d) of the frame body 13 (113). (Fixed convex part 14 (114) provided so that it may project circularly centering on (axial core C2), and fixed part 20 (120) is outer peripheral surface 14a (of fixed convex part 14 (114)) 114a) has an inner peripheral surface 20b (120b).

  In this case, by fixing the fixing portion 20 (120) to the frame 10 (110) at any one of a plurality of fixing positions in the circumferential direction of the fixing convex portion 14 (114) eccentric with respect to the spool shaft 2. The distance between the spool shaft 2 and the heel mounting portion 12 can be easily changed.
