It is also possible to function as.

Further, by mounting each of the bail support members 40 and 41 on the inner peripheral side of the rotor arms 31 and 32, the radius of rotation of the fishing line guide mechanism 45 is reduced, so that it is difficult for the fishing rod to reach the hands of the fishing rod. Therefore, the spool 4 and the fishing rod can be brought closer by shortening the rod mounting portion 12, and the overall size can be reduced.

The reference numerals 0 and 41 are arranged such that their swing surfaces are orthogonal to the swing axis M.

[Structure of fishing line guide mechanism] Next, FIGS.
The fishing line guide mechanism 42 will be described in more detail with reference to FIG. The fishing line guide mechanism 42 includes a fixed shaft 43 having one end fixed to the first bail support member 40, a fixed shaft cover 44 formed integrally with the fixed shaft 43, a substantially cylindrical line roller 45, and a veil 46. have. The both ends of the bail 46 are fixed to the second bail support member 41 and the fixed shaft cover 44, and the bail 46 is disposed so as to be curved outward in the circumferential direction of the spool 4.
The fishing line is guided to the line roller 45 via the fixed shaft cover 44. Here, the fishing line guide side contact portion 4 of the fixed shaft cover 44 and the line roller side portion 46a of the bail 46 (FIG. 2).
The fixed shaft cover and the bail 46 are configured such that a distance R between the fishing line contact portion 6b (FIG. 1) and the fishing line contact portion on the spool 4 becomes shorter from the bail 46 toward the line roller 45.

As shown in FIG. 5, the fixed shaft 43 is a member formed integrally with the fixed shaft cover 44 by cutting. The fixed shaft 43 has a base end extending from the fixed shaft cover 44 and a front end fixed to a fishing line guiding member 47 formed at a front end of the first bail support member 40 by a fixing screw 56. The fishing line guiding member 47 is a first bail support member 4.
At the tip of 0, it protrudes in the shape of a cylindrical disk and is integrally formed. Further, the fixed shaft 45 is positioned in the rotation direction such that the vertex of the fixed shaft cover 44 faces a predetermined direction, and is fitted into the fishing line guiding member 47.

The fixed shaft cover 44 has a substantially conical shape with its apex deviated from the center, and the apex 44a faces rearward of the reel with respect to the axis of the fixed shaft 43 and radially outward of the spool 4. ing. A bale 46 is smoothly joined to the ridge 44b at the ridge 44b near the vertex 44a of the cone. The joint between the bail 46 and the fixed shaft cover 44 is deviated from the vertex 44a of the cone toward the fishing line guide side. A recess 44d is formed in the ridge 44c of the fixed shaft cover 44 on the side opposite to the yarn guide. Further, the decreasing rate of the distance R (FIG. 2) between the vicinity of the joint between the bail 46 and the fixed shaft cover 44 and the line roller 45 to the fishing line contact portion of the spool 4 is greater than the decreasing rate up to that point.

The line roller 45 has a fixed shaft 43 and a bearing 4.
8 so as to be rotatable. The bearing 48 holds the fixed shaft 4 between the fishing line guiding member 47 and the fixed shaft cover 44.
3 is fitted. One end of the inner ring 48a of the bearing 48 is
The other end comes into contact with the fishing line guiding member 47 and the fixed shaft cover 4
4 is in contact with a spacer 49 disposed between the first and second spacers 4. Thus, the inner ring 48a is positioned in the axial direction.

The line roller 45 is fitted into the outer ring 48b of the rolling bearing 48 so as not to move in the direction of the fixed shaft cover, and has a circumferential groove 45a which is a guide portion for guiding the fishing line to the spool 4 is formed on the outer peripheral surface. . Line roller 45
Has a locking portion 45b on the inner peripheral surface that protrudes inward so as to lock on the end surface of the outer race 48b of the bearing 48 on the fishing line guiding member 47 side. As a result, the line roller 45 cannot be moved in the direction of the fixed shaft cover 44, and a slight gap is always formed between the line roller 45 and the fixed shaft cover 44.

A thrust receiving ring 50 made of a synthetic resin such as Duracon is disposed between the fishing line guiding member 47 and the end surface of the line roller 45 on the fishing line guiding member 47 side. The thrust receiving ring 50 prevents the line roller 45 from directly contacting the fishing line guiding member 47. [Structure of Spool] The spool 4 is disposed between the first rotor arm 31 and the second rotor arm 32 of the rotor 3 and is fixed to the tip of the spool shaft 20. The spool 4 has a tapered cylindrical bobbin trunk 4a around which a fishing line is wound around the outer periphery, a rear flange 4b integrally formed with a larger diameter at the rear of the bobbin trunk 4a, and a front of the bobbin trunk 4a. And a large-diameter front flange portion 4c fixed to the portion. These parts are made of a lightweight metal such as an aluminum alloy and have a small thickness of about 1.2 to 1.5 mm.

A disk-shaped front wall 51 is integrally formed at the tip of the bobbin trunk 4a, and a boss 52 fixed to the spool shaft 20 by a pin 53 is formed at the center thereof. I have. The bobbin trunk 4a extends to the outer peripheral side of the cylindrical portion 30 of the rotor 3, and has a trunk length longer than that of a normal spinning reel. The flange height of both flange portions 4b and 4c is lower than that of a normal spinning reel. As a result, the resistance at the time of releasing the line is reduced, so that even when a thin fishing line is wound around the bobbin trunk 4a, the fishing line is hardly twisted.

A ring-shaped groove 54 is formed in the inner peripheral portion of the rear flange 4b. A damping ring 55 is fitted into the groove 54. The vibration damping ring 55 is a ring made of synthetic resin having elasticity such as a Duracon and the like.
As shown in the figure, the shape of the arc is partially cut out.
The outer diameter D1 (FIG. 6) of the vibration damping ring 55 is larger than the inner diameter D2 (FIG. 4) of the groove 54. For this reason, when fitting the vibration damping ring 55 into the groove 54, both ends of the notch of the vibration damping ring 55 are gripped with a slight force and the diameter is reduced to be smaller than the inner diameter D3 of the edge of the groove 54. And fit it.
As a result, the vibration damping ring 55 is attached to the groove 54 using the elasticity of the synthetic resin.

When such a vibration damping ring 55 made of synthetic resin is mounted on the thin spool 4, even if the fishing line hits the spool 4 when the fishing line is wound up, vibration caused by contact is suppressed by the vibration damping ring 55, and Is less likely to vibrate. Therefore, even when the fishing line comes into contact with the spool 4 when the fishing line is wound on the metal spool 4, noise such as a bell sound is less likely to be generated.

Further, since the vibration damping ring 55 is mounted on the inner peripheral surface of the spool 4, the vibration damping ring 55 does not hinder the winding of the yarn, and the size of the entire spool can be suppressed. Since the vibration damping ring 55 is made of synthetic resin,
Vibration of the metal spool 4 can be further suppressed by the synthetic resin that does not easily vibrate, and an increase in weight due to the addition of the vibration damping ring 55 can be suppressed.

Further, since the synthetic resin has elasticity and the vibration damping ring 55 is mounted on the spool 4 by utilizing the elasticity of the synthetic resin, an attaching member for attaching the vibration damping ring 55 becomes unnecessary, and the vibration damping ring 55 becomes unnecessary. The attachment of the vibration ring 55 is facilitated, and the vibration can be more positively suppressed by urging the spool 4 by elasticity. In addition, vibration damping ring 5
5 is formed integrally with the bobbin trunk portion 4a, and is mounted on the inner peripheral surface of the rear flange portion 4b having a larger diameter and a large free space therein, so that the spool 4 is mounted even when the vibration damping ring 55 is mounted. Does not increase in size.

[Operation and Operation of Reel] In this spinning reel, during casting, the bail 46 is tilted from the yarn winding side to the yarn releasing side. Accordingly, the first and second bail support members 40 and 41 rotate in the same direction about the swing axis M. At this time, the first and second bail support members 4
The first and second bail support members 40 and 40 are disposed on the inner peripheral side of the first and second rotor arms 31 and 32, and the swing shaft M is inclined rearward with respect to the spool shaft 20. The line roller 45 at the tip moves further inward than the position in the yarn winding posture. For this reason, the fishing line fed during casting is less likely to become entangled with the first bail support member 40 and the line roller 45.

At the time of winding the fishing line, the bail 43 is lowered to the line winding posture. This is automatically performed by the action of a cam and a spring (not shown) when the handle 1 is rotated in the line winding direction. When the handle 1 is rotated in the line winding direction, this rotational force is transmitted to the pinion gear 14 via the handle shaft 12 and the master gear 13. The torque transmitted to the pinion gear 14 is transmitted to the rotor 3 via the front portion of the pinion gear 14, and the rotor 3 rotates in the line winding direction.

When the bale 43 falls down to the line winding position and the rotor 3 rotates, the fishing line in contact with the rear portion (the contact portion on the fishing line guide side) of the bail 46 is guided to the fixed shaft cover 44 by the bail 46. The fishing line guided by the fixed shaft cover 44 is guided by a line roller 45, the direction of the fishing line is changed by the line roller 45, and the fishing line is wound around the outer periphery of the spool 4.

The distance R between the fishing line guide side contact portion of the fixed roller cover 44 and the line roller side portion 46a of the bail 46 and the fishing line contact portion on the spool 4 becomes shorter as going from the bail 46 to the line roller 45. Since the bail 46 and the fixed shaft cover 44 are configured, the distance from the spool 4 does not increase or decrease, and the fishing line is less likely to be caught. Therefore, the fishing line can be smoothly guided from the bail 46 to the line roller 45.

The fixed shaft cover 44 has a conical shape, and one end of the bail 46 is smoothly joined to the ridge 44b near the vertex 44a of the cone, so that the convex vertex 44a on which the fishing line is easily caught is formed. Can be concealed by the veil 46 to avoid it. Therefore, the fishing line is guided to the line roller 45 more smoothly. In addition, since the vertex 44a of the cone faces rearward of the reel and radially outward of the spool 4 with respect to the axis of the fixed shaft 43,
In the fixed shaft cover 44, a configuration for shortening the distance from the spool 4 can be easily realized.

Since the joint between the bail 46 and the fixed shaft cover 44 is biased toward the fishing line guide side from the apex 44a of the cone, the apex 44a does not protrude toward the line guide side, so that the fishing line is smoother. Will be guided to. Further, since the recessed portion 44d is formed in the ridge portion 44c of the fixed shaft cover 44 on the side opposite to the yarn guide portion side, the missing portion 44d is formed.
Therefore, it is possible to reduce the weight and to maintain the balance of the rotor 3 optimally by the size of the missing portion 44d.

The rate of decrease in the distance R from the vicinity of the joint between the bail 46 and the fixed shaft cover 44 to the line roller 45 and the spool 4 is greater than the rate of decrease of the bale up to that point. Even if there is a delicate step at the joint with the fixed shaft cover 44, the reduction rate increases there, and the fishing line jumps over the joint with force and is guided smoothly to the line roller 45.

Further, since the fixed shaft cover 44 and the fixed shaft 43 are integrally manufactured by cutting, the number of assembling steps and the number of processing steps of parts are reduced, and the manufacturing cost can be reduced.
On the other hand, the screw shaft 21 is rotated by the intermediate gear 23 meshing with the pinion gear 14, and the slider 22 meshing with the spiral groove 21a of the screw shaft 21 is guided by the guide shafts 24a and 24b to move in the front-back direction. Therefore, the spool shaft 20 and the spool 4 reciprocate in the front-rear direction, and the fishing line guided to the spool 4 by the fishing line guide mechanism 42 is wound substantially uniformly in the front-rear direction on the outer peripheral surface of the bobbin trunk 4a of the spool 4. Can be

In the above operation, the fishing line that has entered the circumferential groove 45a of the line roller 45 is urged toward the fixed shaft cover 44, and the line roller 45 is urged toward the fixed shaft cover 44 by the reaction. However, since the inner peripheral surface of the line roller 45 cannot be moved in the direction of the fixed shaft cover 44 by the locking portion 45b, even if the line roller 45 is urged to the fixed shaft cover 44 side, the fixed shaft cover 44 The line roller 45 is hard to contact.

[Other Embodiments] (a) The type of the spinning reel is not limited to the above embodiment, and the present invention can be applied to a type having a drag mechanism or a type having a rotor braking mechanism. (B) The shape of the damping member is not limited to the ring shape, but may be any shape provided that it is provided on the spool body. Further, the mounting site is not limited to the inner peripheral portion of the spool body.

(C) The damping member may be formed integrally with the spool body.

[0041]

According to the present invention, even if the fishing line is wound around the outer periphery and makes contact, the vibration caused by the contact is suppressed by the vibration damping member. For this reason, noise is less likely to be generated even when the fishing line comes into contact with the metal spool when it is wound.

4 and the nut 34 is connected to the pinion gear 1.
4 is screwed into the threaded portion. A bearing 35 for rotatably supporting the nut 34 with respect to the spool shaft 20 is disposed on an inner peripheral portion of the nut 34.

A mechanism 37 for preventing reverse rotation of the rotor 3 is disposed inside the cylindrical portion 30. Reverse rotation prevention mechanism 37
Has a roller type one-way clutch (not shown) and an operation mechanism 38 for switching the one-way clutch between an operating state and a non-operating state. In the one-way clutch, an outer ring is fixed to the housing 10, and an inner ring is fixed to the pinion gear 14.

And is prevented from entering through the gap between the spool shaft 20 and the shaft shaft 20. As shown in FIGS. 1 to 3, first and second bail support members 40 and 41 are swingably mounted on the inner peripheral sides of the distal ends of the first and second rotor arms 31 and 32, respectively. First veil support member 40
Is rotatably supported by the first rotor arm 31 by two bearings 40a. First and second bail support members 4
A fishing line guide mechanism 42 for guiding the fishing line to the spool 4 is mounted at the tip of 0,41. Here, the second bail support member 41 is made of, for example, a material having a higher specific gravity than other portions, and a balancer for eliminating imbalance during rotation caused by the first bale support member 40 and the fishing line guide mechanism 42. It is also possible to function as.

Further, by mounting each of the bail support members 40 and 41 on the inner peripheral side of the rotor arms 31 and 32, the radius of rotation of the fishing line guide mechanism 45 is reduced, so that it is difficult for the fishing rod to reach the hands of the fishing rod. Therefore, the spool 4 and the fishing rod can be brought closer by shortening the rod mounting portion 12, and the overall size can be reduced. Here, the bail support members 40 and 41 are swingable about one swing axis M. The point at which the pivot axis M intersects with the first bail support member mounting surface of the first rotor arm 31 is defined as the pivot center C1, and the pivot axis M and the second bail support member mounting surface of the second rotor arm 32 are set.

[Structure of fishing line guide mechanism] Next, FIGS.
The fishing line guide mechanism 42 will be described in more detail with reference to FIG. The fishing line guide mechanism 42 includes a fixed shaft 43 having one end fixed to the first bail support member 40, a fixed shaft cover 44 formed integrally with the fixed shaft 43, a substantially cylindrical line roller 45, and a veil 46. have. The both ends of the bail 46 are fixed to the second bail support member 41 and the fixed shaft cover 44, and the bail 46 is disposed so as to be curved outward in the circumferential direction of the spool 4.
The fishing line is guided to the line roller 45 via the fixed shaft cover 44. Here, the fishing line guide side contact portion 4 of the fixed shaft cover 44 and the line roller side portion 46a of the bail 46 (FIG. 2).
The fixed shaft cover and the bail 46 are configured such that a distance R between the fishing line contact portion 6b (FIG. 1) and the fishing line contact portion on the spool 4 becomes shorter from the bail 46 toward the line roller 45.

As shown in FIG. 5, the fixed shaft 43 is a member formed integrally with the fixed shaft cover 44 by cutting. The fixed shaft 43 has a base end extending from the fixed shaft cover 44 and a front end fixed to a fishing line guiding member 47 formed at a front end of the first bail support member 40 by a fixing screw 56. The fishing line guiding member 47 is a first bail support member 4.
At the tip of 0, it protrudes in the shape of a cylindrical disk and is integrally formed. Further, the fixed shaft 45 is positioned in the rotation direction such that the vertex of the fixed shaft cover 44 faces a predetermined direction, and is fitted into the fishing line guiding member 47.

The fixed shaft cover 44 has a substantially conical shape with its apex deviated from the center, and the apex 44a faces rearward of the reel with respect to the axis of the fixed shaft 43 and radially outward of the spool 4. ing. A bale 46 is smoothly joined to the ridge 44b at the ridge 44b near the vertex 44a of the cone. The joint between the bail 46 and the fixed shaft cover 44 is deviated from the vertex 44a of the cone toward the fishing line guide side. A recess 44d is formed in the ridge 44c of the fixed shaft cover 44 on the side opposite to the yarn guide. Further, the decreasing rate of the distance R (FIG. 2) between the vicinity of the joint between the bail 46 and the fixed shaft cover 44 and the line roller 45 to the fishing line contact portion of the spool 4 is greater than the decreasing rate up to that point.

The line roller 45 has a fixed shaft 43 and a bearing 4.
8 so as to be rotatable. The bearing 48 holds the fixed shaft 4 between the fishing line guiding member 47 and the fixed shaft cover 44.
3 is fitted. One end of the inner ring 48a of the bearing 48 is
The other end comes into contact with the fishing line guiding member 47 and the fixed shaft cover 4
4 is in contact with a spacer 49 disposed between the first and second spacers 4. Thus, the inner ring 48a is positioned in the axial direction.

The line roller 45 is fitted into the outer ring 48b of the rolling bearing 48 so as not to move in the direction of the fixed shaft cover, and has a circumferential groove 45a which is a guide portion for guiding the fishing line to the spool 4 is formed on the outer peripheral surface. . Line roller 45
Has a locking portion 45b on the inner peripheral surface that protrudes inward so as to lock on the end surface of the outer race 48b of the bearing 48 on the fishing line guiding member 47 side. As a result, the line roller 45 cannot be moved in the direction of the fixed shaft cover 44, and a slight gap is always formed between the line roller 45 and the fixed shaft cover 44.

A thrust receiving ring 50 made of a synthetic resin such as Duracon is disposed between the fishing line guiding member 47 and the end surface of the line roller 45 on the fishing line guiding member 47 side. The thrust receiving ring 50 prevents the line roller 45 from directly contacting the fishing line guiding member 47. [Structure of Spool] The spool 4 is disposed between the first rotor arm 31 and the second rotor arm 32 of the rotor 3 and is fixed to the tip of the spool shaft 20. The spool 4 has a tapered cylindrical bobbin trunk 4a around which a fishing line is wound around the outer periphery, a rear flange 4b integrally formed with a larger diameter at the rear of the bobbin trunk 4a, and a front of the bobbin trunk 4a. And a large-diameter front flange portion 4c fixed to the portion. These parts are made of a lightweight metal such as an aluminum alloy and have a small thickness of about 1.2 to 1.5 mm.

A disk-shaped front wall 51 is integrally formed at the tip of the bobbin trunk 4a, and a boss 52 fixed to the spool shaft 20 by a pin 53 is formed at the center thereof. I have. The bobbin trunk 4a extends to the outer peripheral side of the cylindrical portion 30 of the rotor 3, and has a trunk length longer than that of a normal spinning reel. The flange height of both flange portions 4b and 4c is lower than that of a normal spinning reel. As a result, the resistance at the time of releasing the line is reduced, so that even when a thin fishing line is wound around the bobbin trunk 4a, the fishing line is hardly twisted.

A ring-shaped groove 54 is formed in the inner peripheral portion of the rear flange 4b. A damping ring 55 is fitted into the groove 54. The vibration damping ring 55 is a ring made of synthetic resin having elasticity such as a Duracon and the like.
As shown in the figure, the shape of the arc is partially cut out.
The outer diameter D1 (FIG. 6) of the vibration damping ring 55 is larger than the inner diameter D2 (FIG. 4) of the groove 54. For this reason, when fitting the vibration damping ring 55 into the groove 54, both ends of the notch of the vibration damping ring 55 are gripped with a slight force and the diameter is reduced to be smaller than the inner diameter D3 of the edge of the groove 54. And fit it.
As a result, the vibration damping ring 55 is attached to the groove 54 using the elasticity of the synthetic resin.

When such a vibration damping ring 55 made of synthetic resin is mounted on the thin spool 4, even if the fishing line hits the spool 4 when the fishing line is wound up, vibration caused by contact is suppressed by the vibration damping ring 55, and Is less likely to vibrate. Therefore, even when the fishing line comes into contact with the spool 4 when the fishing line is wound on the metal spool 4, noise such as a bell sound is less likely to be generated.

Further, since the vibration damping ring 55 is mounted on the inner peripheral surface of the spool 4, the vibration damping ring 55 does not hinder the winding of the yarn, and the size of the entire spool can be suppressed. Since the vibration damping ring 55 is made of synthetic resin,
Vibration of the metal spool 4 can be further suppressed by the synthetic resin that does not easily vibrate, and an increase in weight due to the addition of the vibration damping ring 55 can be suppressed.

Further, since the synthetic resin has elasticity and the vibration damping ring 55 is mounted on the spool 4 by utilizing the elasticity of the synthetic resin, an attaching member for attaching the vibration damping ring 55 becomes unnecessary, and the vibration damping ring 55 becomes unnecessary. The attachment of the vibration ring 55 is facilitated, and the vibration can be more positively suppressed by urging the spool 4 by elasticity. In addition, vibration damping ring 5
5 is formed integrally with the bobbin trunk portion 4a, and is mounted on the inner peripheral surface of the rear flange portion 4b having a larger diameter and a large free space therein, so that the spool 4 is mounted even when the vibration damping ring 55 is mounted. Does not increase in size.

[Operation and Operation of Reel] In this spinning reel, during casting, the bail 46 is tilted from the yarn winding side to the yarn releasing side. Accordingly, the first and second bail support members 40 and 41 rotate in the same direction about the swing axis M. At this time, the first and second bail support members 4
The first and second bail support members 40 and 40 are disposed on the inner peripheral side of the first and second rotor arms 31 and 32, and the swing shaft M is inclined rearward with respect to the spool shaft 20. The line roller 45 at the tip moves further inward than the position in the yarn winding posture. For this reason, the fishing line fed during casting is less likely to become entangled with the first bail support member 40 and the line roller 45.

At the time of winding the fishing line, the bail 43 is lowered to the line winding posture. This is automatically performed by the action of a cam and a spring (not shown) when the handle 1 is rotated in the line winding direction. When the handle 1 is rotated in the line winding direction, this rotational force is transmitted to the pinion gear 14 via the handle shaft 12 and the master gear 13. The torque transmitted to the pinion gear 14 is transmitted to the rotor 3 via the front portion of the pinion gear 14, and the rotor 3 rotates in the line winding direction.

When the bale 43 falls down to the line winding position and the rotor 3 rotates, the fishing line in contact with the rear portion (the contact portion on the fishing line guide side) of the bail 46 is guided to the fixed shaft cover 44 by the bail 46. The fishing line guided by the fixed shaft cover 44 is guided by a line roller 45, the direction of the fishing line is changed by the line roller 45, and the fishing line is wound around the outer periphery of the spool 4.

The distance R between the fishing line guide side contact portion of the fixed roller cover 44 and the line roller side portion 46a of the bail 46 and the fishing line contact portion on the spool 4 becomes shorter as going from the bail 46 to the line roller 45. Since the bail 46 and the fixed shaft cover 44 are configured, the distance from the spool 4 does not increase or decrease, and the fishing line is less likely to be caught. Therefore, the fishing line can be smoothly guided from the bail 46 to the line roller 45.

The fixed shaft cover 44 has a conical shape, and one end of the bail 46 is smoothly joined to the ridge 44b near the vertex 44a of the cone, so that the convex vertex 44a on which the fishing line is easily caught is formed. Can be concealed by the veil 46 to avoid it. Therefore, the fishing line is guided to the line roller 45 more smoothly. In addition, since the vertex 44a of the cone faces rearward of the reel and radially outward of the spool 4 with respect to the axis of the fixed shaft 43,
In the fixed shaft cover 44, a configuration for shortening the distance from the spool 4 can be easily realized.

Since the joint between the bail 46 and the fixed shaft cover 44 is biased toward the fishing line guide side from the apex 44a of the cone, the apex 44a does not protrude toward the line guide side, so that the fishing line is smoother. Will be guided to. Further, since the recessed portion 44d is formed in the ridge portion 44c of the fixed shaft cover 44 on the side opposite to the yarn guide portion side, the missing portion 44d is formed.
Therefore, it is possible to reduce the weight and to maintain the balance of the rotor 3 optimally by the size of the missing portion 44d.

The rate of decrease in the distance R from the vicinity of the joint between the bail 46 and the fixed shaft cover 44 to the line roller 45 and the spool 4 is greater than the rate of decrease of the bale up to that point. Even if there is a delicate step at the joint with the fixed shaft cover 44, the reduction rate increases there, and the fishing line jumps over the joint with force and is guided smoothly to the line roller 45.

Further, since the fixed shaft cover 44 and the fixed shaft 43 are integrally manufactured by cutting, the number of assembling steps and the number of processing steps of parts are reduced, and the manufacturing cost can be reduced.
On the other hand, the screw shaft 21 is rotated by the intermediate gear 23 meshing with the pinion gear 14, and the slider 22 meshing with the spiral groove 21a of the screw shaft 21 is guided by the guide shafts 24a and 24b to move in the front-back direction. Therefore, the spool shaft 20 and the spool 4 reciprocate in the front-rear direction, and the fishing line guided to the spool 4 by the fishing line guide mechanism 42 is wound substantially uniformly in the front-rear direction on the outer peripheral surface of the bobbin trunk 4a of the spool 4. Can be

In the above operation, the fishing line that has entered the circumferential groove 45a of the line roller 45 is urged toward the fixed shaft cover 44, and the line roller 45 is urged toward the fixed shaft cover 44 by the reaction. However, since the inner peripheral surface of the line roller 45 cannot be moved in the direction of the fixed shaft cover 44 by the locking portion 45b, even if the line roller 45 is urged to the fixed shaft cover 44 side, the fixed shaft cover 44 The line roller 45 is hard to contact.

[Other Embodiments] (a) The type of the spinning reel is not limited to the above embodiment, and the present invention can be applied to a type having a drag mechanism or a type having a rotor braking mechanism. (B) The shape of the damping member is not limited to the ring shape, but may be any shape provided that it is provided on the spool body. Further, the mounting site is not limited to the inner peripheral portion of the spool body.

(C) The damping member may be formed integrally with the spool body.

[0041]

According to the present invention, even if the fishing line is wound around the outer periphery and makes contact, the vibration caused by the contact is suppressed by the vibration damping member. For this reason, noise is less likely to be generated even when the fishing line comes into contact with the metal spool when it is wound.
