  In the conventional configuration, since the cam gear portion is disposed below and behind the drive gear, the center of gravity of the entire reel is disposed at a position entirely away from the fishing rod. For this reason, the sensation weight felt at the time of casting becomes heavy. In addition, the thickness of the lower part of the reel body is increased, making it difficult to realize a compact reel body.

  SUMMARY OF THE INVENTION An object of the present invention is to reduce the bodily sensation weight and reduce the thickness of the lower portion of the reel body in a reduction gear type oscillating mechanism.

The spinning reel oscillating mechanism according to the first aspect of the present invention is configured so that a spool on which a fishing line is wound by a rotor rotatably mounted on a spinning reel mounted on a fishing rod is moved back and forth in conjunction with the rotation of a handle via a spool shaft. This is a mechanism for moving, and includes a drive gear, a cam gear portion, a slider portion, and a guide portion. The drive gear is a gear provided at a distance from the master gear on a master gear shaft on which a master gear for rotating the rotor in conjunction with the rotation of the handle is mounted. The cam gear portion has a cam portion on the side surface, is disposed on the fishing rod mounting side from the master gear shaft, and is mounted on the reel body so as to be rotatable about a first shaft substantially parallel to the master gear shaft and interlocked with the drive gear. The gear rotates. The slider portion has a cam receiving portion that engages with the cam portion of the cam gear portion, and is attached to the rear end portion of the spool shaft so as not to move forward and backward. The guide portion is provided on the reel body and guides the slider portion so as to be movable back and forth. The cam receiving portion is disposed on the fishing rod mounting side from the spool shaft and is superimposed on the spool shaft in the master gear shaft direction.

  In this oscillating mechanism, when the handle rotates, the drive gear rotates and the cam gear portion rotates in conjunction therewith. When the cam gear portion rotates, the slider portion reciprocates back and forth due to the engagement between the cam portion and the cam receiving portion, and the spool reciprocates back and forth via the spool shaft. Here, since the cam gear portion is arranged on the fishing rod mounting side from the master gear shaft provided with the drive gear, the position of the cam gear portion approaches the fishing rod. For this reason, the center of gravity moves to the fishing rod mounting side, and the bodily sensation load is reduced. In addition, since the cam gear portion is disposed on the fishing rod mounting side, it is possible to reduce the thickness of the opposite side, that is, the lower portion of the reel body.

  The spinning reel oscillating mechanism according to a second aspect of the present invention is the mechanism according to the first aspect, wherein the first gear meshes with the drive gear and has a larger number of teeth than the drive gear, and is arranged concentrically with the first gear, and the teeth from the cam gear portion. There is a second gear that is small in number and meshes with the cam gear portion, and further includes an intermediate gear portion that is mounted on the reel body so as to be rotatable about a second axis substantially parallel to the master gear shaft. In this case, since the speed can be reduced between the drive gear, the first gear, the second gear, and the cam gear portion, the forward / backward movement speed of the spool can be reduced with respect to the rotation of the rotor, and the speed reduction gear type The fishing line can be tightly wound around the spool in the rating mechanism.

  The spinning reel oscillating mechanism according to a third aspect of the present invention is the reel according to the second aspect, wherein the second shaft is disposed closer to the fishing rod mounting side than the first shaft. In this case, since the stepped gear portion is arranged closer to the fishing rod mounting side than the cam gear portion, the bodily sensation load does not increase so much even if the stepped gear portion is provided, and the thickness of the lower portion of the reel body can be reduced.

  The spinning reel oscillating mechanism according to a fourth aspect is the mechanism according to the second or third aspect, wherein the drive gear and the first gear are circular gears, and the second gear and the cam gear portion are non-circular gears. In this case, by using the non-circular gear, the constant speed rotation of the second gear can be converted into the non-constant speed rotation of the cam gear portion, and the slider portion can be brought close to a constant speed linear motion.

  The spinning reel oscillating mechanism according to a fifth aspect of the present invention is the mechanism according to any one of the first to fourth aspects, wherein the cam receiving portion is disposed closer to the fishing rod mounting side than the spool shaft. In this case, since the cam receiving portion is disposed above the spool shaft, the slider portion can be disposed between the master gear and the drive gear, and the thickness of the entire reel can be reduced.

  A spinning reel oscillating mechanism according to a sixth aspect of the present invention is the mechanism according to any one of the first to fifth aspects, wherein the cam receiving portion is disposed closer to the master gear than the spool shaft. In this case, since the cam receiving portion is disposed on the master gear side with respect to the spool shaft, the slider portion can be disposed between the spool shaft and the master gear, and the thickness of the entire reel can be reduced. .

  The spinning reel oscillating mechanism according to a seventh aspect of the present invention is the mechanism according to any one of the first to sixth aspects, wherein the guide portion is disposed substantially parallel to the spool shaft, and the fishing rod mounting side of the slider portion and the opposite side thereof. And two guide shafts for guiding the slider portion. In this case, the stroke can be increased as compared with the case where the cam groove is linearly formed in the vertical direction. In this case, since the slider portion is guided by the two guide shafts, the slider portion can be smoothly moved back and forth. .

  An oscillating mechanism for a spinning reel according to an eighth aspect of the present invention is the mechanism according to any of the first to seventh aspects, wherein the cam portion has a cam pin protruding toward the slider portion, and the cam receiving portion is associated with the cam pin. In addition, the first end portion on the fishing rod mounting side has a cam groove formed linearly and obliquely located in front of the second end portion on the opposite side. In this case, when the slider portion moves forward and approaches the master gear shaft, the master gear shaft can be easily displaced, so that the entire length of the reel can be shortened, and the stroke of the slider portion can be changed to the cam pin. It can be larger than the diameter of rotation.

  The spinning reel oscillating mechanism according to a ninth aspect is the mechanism according to any one of the first to seventh aspects, wherein the cam portion has a cam pin protruding toward the slider portion, and the cam receiving portion is engaged with the cam pin. The first end portion on the fishing rod mounting side is located in front of the second end portion on the opposite side, and is curved forward and convex from the first end portion, and is directed rearward from the curved portion. And a cam groove including a first straight portion that is linearly inclined and a second straight portion that extends linearly from the first straight portion toward the second end portion. In this case, when the slider moves forward and approaches the master gear shaft, the master gear shaft can be easily swept away, so that the length of the entire reel can be shortened, and the curved portion can be used to advance or retract the spool. The constant speed rotation of the driving gear at the time can be changed to an inconstant speed rotation of the cam gear portion, and the slider portion can be brought close to the constant speed rotation.

  According to the present invention, since the cam gear portion is arranged on the fishing rod mounting side from the master gear shaft provided with the drive gear, the position of the cam gear portion approaches the fishing rod. For this reason, the center of gravity moves to the fishing rod mounting side from the conventional one, and the bodily sensation load is reduced. In addition, since the cam gear portion is disposed on the fishing rod mounting side, it is possible to reduce the thickness of the opposite side, that is, the lower portion of the reel body.

And a leg portion 2b for connecting the reel body 2a. The reel body 2a has a mechanism mounting space inside, and its side is open. This opening is covered with a lid member 2d.

  Inside the reel body 2a, a rotor driving mechanism 5 for rotating the rotor 3 and an oscillating mechanism 6 for reciprocating the spool 4 back and forth in conjunction with the rotation of the handle 1 are provided.

  The rotor 3 is made of, for example, synthetic resin or metal, and is rotatably supported by the reel body 2. The rotor 3 includes a cylindrical portion 3a and a first arm portion 3b and a second arm portion 3c provided on the side of the cylindrical portion 3a so as to face each other. A boss 3f having a through hole 3e is formed at the center of the front wall 3d of the cylindrical portion 3a. The spool shaft 8 and the pinion gear 12 (described later) pass through the through hole 3e. A bail arm 9 is provided at the tip of the first arm portion 3b and the tip of the second arm portion 3c so as to be swingable between a yarn winding posture and a yarn releasing posture. The fishing line is guided to the spool 4 by the bail arm 9.

  The bail arm 9 includes first and second bail support members 41 and 42 and a bail 43 that connects them. The first and second bail support members 41 and 42 are swingably attached to the tips of the first and second arm portions 3b and 3c, respectively.

  The bail arm 9 returns from the yarn releasing posture to the yarn winding posture in conjunction with the rotation of the rotor in the yarn winding direction by the bale reversing mechanism 7 attached to the first arm portion 3b. The bale reversing mechanism 7 is disposed in the storage space 48 of the first arm portion 3b. The bale reversing mechanism 7 is provided to return the bail arm 9 from the yarn releasing posture to the yarn winding posture in conjunction with the rotation of the rotor 3 and to maintain the state in both postures. The bale reversing mechanism 7 also has a function of braking the rotation of the rotor 3 when the bail arm 9 is disposed in the yarn releasing posture.

  As shown in FIGS. 2 to 4, the bale reversing mechanism 7 includes a toggle spring mechanism 50 that is swingably mounted on the first arm portion 3 b in the storage space 48, and is substantially movable back and forth in the storage space 48. The mounted moving member 51, a switching member 52 (FIG. 3) that is detachably mounted on the front end surface of the reel body 2 a so as to be in contact with the moving member 51, and a braking member 65 for braking the rotor 3 are provided. is doing.

  The toggle spring mechanism 50 urges the bail arm 9 to be distributed between a yarn winding posture and a yarn releasing posture. The moving member 51 is a rod-like member whose front end is locked to the first bail support member 41 and whose rear end is disposed to face the front portion of the reel body 2a. Move to. Specifically, when the bail arm 9 is in the yarn winding posture, the moving member 51 is disposed at a forward position where the rear end portion cannot contact the switching member 52 and cannot contact the braking member 65, and is in the yarn releasing posture. At this time, the rear end portion is arranged so as to be in contact with the switching member 52 and in contact with the braking member 65. When the moving member 51 contacts the switching member 52 and moves from the retracted position to the advanced position, the bail arm 9 returns from the yarn releasing posture to the yarn winding posture.

  The switching member 52 is a member made of a synthetic resin such as a polyamide-based synthetic resin or polyacetal, for example. As shown in FIGS. 3 and 4, the switching member 52 is detachably screwed to a mounting boss 2h formed at the front portion of the reel body 2a. It has been stopped. The switching member 52 includes a mountain-shaped cam portion 60 having two inclined surfaces 60a and 60b, an arch portion 61 extending from the cam portion 60 toward the center, and a cylindrical mounting portion 62 screwed to the mounting boss 2h. Have. The inclined surface 60a is an inclined surface in which the downstream side in the yarn winding rotation direction of the rotor 3 indicated by an arrow in FIG. 4 protrudes forward toward the rotor 3 from the upstream side. The inclined surface 60b is an inclined surface in which the protruding amount decreases from the protruding portion of the inclined surface 60a toward the downstream side in the yarn winding rotation direction. The amount of protrusion of the projecting ends most projecting of the inclined surfaces 60a and 60b is determined by the death of the toggle spring mechanism 50 when the moving member 51 whose rear end is in contact with the inclined surface 60a presses the bail arm 9 toward the yarn winding posture. It is set to exceed the point. In addition, the bottom surface of the cam portion 60 that comes into contact with the reel body 2a is formed with a recess that fits a positioning projection 2i that is formed to protrude from the front surface of the reel body 2a. And is configured to be prevented from rotating.

  The arch portion 61 has a shape in which the braking member 65 is cut out so as to pass between the arch portion 61 and the front surface of the reel body 2a. The attachment portion 62 is a cylindrical member, and is fixed to the mounting boss 2h of the reel body 2a with a screw.

  The braking member 65 is provided to brake the rotation of the rotor 3 when the bail arm 9 is in the yarn releasing posture. The braking member 65 is an elastic ring-shaped member made of synthetic rubber. On the outer peripheral surface of the braking member 65, a braking surface 65 a configured by a flat circumferential surface is formed except for a portion that avoids the switching member 52. The braking member 65 is attached to the front portion of the reel body 2a having a D-shaped cross section. Therefore, the braking member 65 is mounted in a D shape when viewed from the front. As shown in FIG. 4, the straight portion of the braking member 65 bypasses the rear portion of the arch portion 61 of the switching member 52 while curving backward. As described above, the braking member 65 can be arranged using the limited space effectively by making the braking member 65 bend to the inner peripheral side behind the switching member 52 while curving the braking member 65.

  An introduction surface 65b is formed at the leading end edge of the braking surface 65a of the braking member 65 so as to be continuous with the braking surface 65a. The introduction surface 65b is formed so that the upstream side in the moving direction of the moving member 51 interlocked with the swinging to the yarn releasing posture is further away from the downstream side. In the present embodiment, the introduction surface 65b is continuously rounded with the braking surface 65a. It is formed with a rounded surface. When the introduction surface 65b that is continuously inclined to the braking surface 65a is formed in this way, when the moving member 51 contacts the braking member 65, the rounded rear end portion of the moving member 51 is the introduction surface 65b of the braking member 65. And smoothly contacts the braking surface 65a. For this reason, the posture of the bail arm 9 can be switched smoothly.

  As shown in FIG. 2, the spool 4 is a member made of, for example, metal or synthetic resin, and is disposed between the first arm portion 3 b and the second arm portion 3 c of the rotor 3. The spool 4 is rotatably mounted via a drag mechanism 53 on the tip of a spool shaft 8 that is disposed forward and backward along the axis X. The spool 4 is formed integrally with a cylindrical bobbin trunk 4a around which a fishing line is wound, a large-diameter cylindrical skirt 4b formed integrally with the rear end of the bobbin trunk 4a, and a front end of the bobbin trunk 4a. And a large-diameter front flange portion 4c.

  The rotor drive mechanism 5 includes a master gear 11 having a master gear shaft 11 a that rotates together with a handle shaft 10 to which the handle 1 is fixed, and a pinion gear 12 that meshes with the master gear 11. The master gear shaft 11a is rotatably supported by the reel body 2. The pinion gear 12 is formed in a cylindrical shape, and the spool shaft 8 passes through the center. The front portion of the pinion gear 12 extends through the through hole 3e of the rotor 3 to the spool 4 side. At the front portion 12a, the rotor 3 is fixed to the pinion gear 12 by a nut 13 so as not to rotate. The pinion gear 12 is rotatably supported on the reel body 2 by bearings 14a and 14b at the front portion and the intermediate portion. The nut 13 is prevented from loosening by a retainer 36. The retainer 36 is fixed by screws screwed into screw holes formed in the front wall 3d.

[Configuration of Oscillating Mechanism]
As shown in FIG. 2, the oscillating mechanism 6 is a mechanism for moving the spool 4 fixed in the center of the spool 4 in the front-rear direction and moving the spool 4 in the same direction. The oscillating mechanism 6 includes a drive gear 15 provided on the master gear shaft 11a, an intermediate gear portion 16 that meshes with the drive gear 15, and a cam gear portion 17 that rotates in conjunction with the drive gear 15 via the intermediate gear portion 16. The slider 18 is engaged with the cam gear 17 and fixed to the rear end of the spool shaft 8 so as not to rotate and move, and engages with the cam gear 17 to move back and forth. The slider 18 is provided on the reel body 2a. And a guide part 19 that guides the front and rear in a freely movable manner.

  As shown in FIGS. 5 and 6, the drive gear 15 is a circular gear such as a spur gear having 14 teeth or a helical gear, and is integrated with the master gear 11 at a distance from the master gear 11a. Is provided. The drive gear 15 may be provided separately from the master gear shaft 11a.

  The intermediate gear portion 16 is a disk-shaped member and is rotatably mounted on the reel body 2a around an axis parallel to the master gear shaft 11a. Specifically, as shown in FIG. 6, the reel body 2a is rotatably mounted on a mounting shaft 2f formed on the inner wall of the rear portion of the reel body 2a so as to protrude in parallel with the master gear shaft 11a. As shown in FIG. 5, the mounting shaft 2 f is disposed rearward (rightward in FIG. 5) and closer to the mounting portion 2 c (upward in FIG. 5) than the master gear shaft 11 a. The intermediate gear portion 16 includes a first gear 16a that meshes with the drive gear 15, and a second gear 16b that is disposed concentrically with the first gear 16a. The first gear 16 a is a circular gear such as a spur gear or a helical gear having more teeth than the drive gear 15, for example, 22 teeth. The second gear 16b is a non-circular gear such as a two-leaf elliptical gear having 12 teeth. The first gear 16a and the second gear 16b may be integrally formed or may be formed separately. Moreover, it may be arranged at intervals or may be in close contact. In FIG. 5, two marks 16 c drawn on the side surface of the second gear 16 b indicate the position of the maximum tip diameter.

  The cam gear portion 17 is a disk-shaped member, and is rotatably mounted on the reel body 2 a around an axis parallel to the intermediate gear portion 16. Specifically, as shown in FIG. 6, the reel body 2a is rotatably mounted on a mounting shaft 2g formed on the rear inner wall surface of the reel body 2a so as to protrude in parallel with the master gear shaft 11a. As shown in FIG. 5, the mounting shaft 2g is located behind the mounting shaft 2f, away from the mounting shaft 2f from the mounting portion 2c, and closer to the mounting portion 2c than the master gear shaft 11a (upward in FIG. 5). Has been placed. As a result, in the vertical positional relationship, the mounting shaft 2g is disposed between the master gear shaft 11a and the mounting shaft 2f. Further, in the positional relationship in the front-rear direction, the mounting shaft 2f is disposed between the master gear shaft 11a and the mounting shaft 2g.

  The cam gear portion 17 includes a gear portion 17a formed on the outer peripheral portion and a cylindrical cam pin 17b provided so as to protrude in an axial direction parallel to the master gear shaft 11a. The gear portion 17a is a four-leaf non-circular gear having more teeth than the second gear 16b, for example, having 24 teeth. The gear portion 17a is disposed so that the teeth having the maximum tip circle diameter mesh with the teeth having the minimum tip circle diameter of the second gear 16b. In FIG. 5, the four marks 17 c drawn on the side surface of the cam gear portion 17 indicate the position of the minimum tip circle diameter. Therefore, if the two gears 16b and 17a are engaged with each other so that the two marks 16c and 17c are fitted, normal engagement is ensured and the assembly work is facilitated.

  The slider portion 18 has a cam receiving portion 18a that is formed in a through-groove shape that engages with the cam pin 17b and engages with the cam pin 17b, and is supported by the reel body 2a so as to be reciprocally movable in the spool axis direction. The cam receiving portion 18 a is disposed on the side closer to the mounting portion 2 c than the spool shaft 8 and on the side closer to the master gear 11. A rear end portion 8 a of the spool shaft 8 is mounted on the slider portion 18 so as not to rotate and to move back and forth by a countersunk screw 21 screwed into the lower portion of the slider portion 18. The rear end portion 8a fixed to the slider portion 18 of the spool shaft 8 is formed with a smaller diameter than other portions. For this reason, the spool shaft 8 mounting portion of the slider portion 18 can be reduced in size, and interference with the reel body 2a can be minimized when the slider portion 18 is positioned at the retracted end. Accordingly, the degree of freedom of the design shape of the rear end portion of the reel body 2a can be increased.

  As shown in FIG. 5, the cam receiving portion 18a engages with the cam pin 17b, the first end portion Q1 on the fishing rod mounting side is positioned in front of the second end portion Q2 on the opposite side, and the first end portion Q1. A curved portion 18b that is convexly curved forward from the first straight portion 18c that is formed linearly and obliquely rearward from the curved portion 18b, and a second end portion Q2 from the first linear portion 18c. And a second linear portion 18d extending linearly toward the cam groove.

  The guide portion 19 is guided in the front-rear direction along the spool shaft by two guide shafts 19a and 19b disposed in parallel to the reel body 2a with a space in the vertical direction.

Here, since the cam gear portion 17 is arranged on the fishing rod mounting side from the master gear shaft 11a provided with the drive gear 15, the position of the cam gear portion 17 approaches the fishing rod. For this reason, the center of gravity moves to the fishing rod mounting side from the conventional one, and the bodily sensation load is reduced. Moreover, since the cam gear part 17 is arrange | positioned at the fishing rod mounting | wearing side, thickness reduction of the reverse side, ie, the lower part of the reel main body 2, can be achieved.
[Reel operation and operation]
At the time of casting, casting is performed by tilting the bail arm 9 to the line releasing posture side with the fishing line hooked with the index finger.

  At the time of fishing line winding, the bail arm 9 is tilted to the line winding posture side. When the handle 1 is rotated in the yarn winding direction in this state, the rotational force is transmitted to the pinion gear 12 via the handle shaft 10 and the master gear 11. The rotational force transmitted to the pinion gear 12 is transmitted to the rotor 3 via the front portion 12a of the pinion gear 12.

  On the other hand, with the rotation of the master gear 11, the intermediate gear portion 16 is rotated by the first gear 16a engaged with the drive gear 15, and the cam gear portion 17 is rotated by the engagement of the second gear 16b and the gear portion 17a. 17b is transmitted to the slider portion 18. As a result, the slider portion 18 reciprocates back and forth along the axis X of the spool shaft 8.

  At this time, the speed is reduced between the drive gear 15 and the first gear 16a, and the speed is also reduced between the second gear 16b and the gear portion 17a, the rotation of the handle 1 is greatly reduced, and the rotation of the cam gear portion 17 is reduced. Slower than conventional. For this reason, the reciprocating speed of the spool 4 becomes slow, and the fishing line can be tightly wound around the spool 4. Further, since the second gear 16b and the gear portion 17a are non-circular gears, it is possible to convert the constant velocity circular motion to the non-uniform velocity motion. For this reason, disturbance of the pincushion shape due to fluctuations in the forward / backward moving speed of the spool 4 can be suppressed as compared with the case where a circular gear is used.

  In FIG. 7, the oscillating mechanism 106 includes a drive gear 15 provided on the master gear shaft 11 a, a cam gear portion 117, a slider portion 118, and a guide portion 19. The drive gear 15 is directly meshed with the gear portion 117a of the cam gear portion 117. The cam gear portion 117 is disposed behind the master gear shaft 11a and on the fishing rod mounting side. In addition, the cam receiving portion 118a of the slider portion 118 has a cam groove formed in a linearly slanted right downward direction in which the first end portion Q1 on the mounting portion 2c side is positioned in front of the second end portion Q2 on the opposite side. is doing. Further, both the drive gear 15 and the gear portion 117a use circular gears instead of non-circular gears. Since other configurations are the same as those of the above-described embodiment, description thereof is omitted.
