Description

This invention relates to a fishing reel, and more particularly to a double-bearing reel.

The double-bearing reel described in Patent Document 1 comprises a reel body, a spool rotatably supported by the reel body and on which fishing line is wound, a spool shaft that rotates integrally with the spool, and a braking structure that brakes the rotation of the spool to adjust the release speed when the fishing line is released. The reel body has a boss portion. The braking force applied to the rotation of the spool is adjusted by adjusting a cap member rotatably attached to the boss portion.

Specifically, in the case of the double-bearing reel described in Patent Document 1, the spool shaft, which rotates integrally with the spool, is rotatably positioned relative to the boss portion via a bearing. The braking structure comprises a cap member and a friction member, and is rotatably mounted relative to the boss portion. The friction member is positioned between the cap member and the tip of the spool shaft. By rotating the cap member, the frictional force between the spool shaft and the friction member is adjusted, thereby providing a braking force to the rotation of the spool, which rotates integrally with the spool shaft.

Japanese Patent Publication No. 2011-15653

In conventional fishing reels, the rotation of the spool is braked by pressing the end of the rotating shaft (in this case, the spool shaft) against a friction member. However, this method has the problem that sufficient braking force cannot be obtained because the contact surface between the rotating shaft and the friction member is small. For example, in baitcasting reels for large fish, especially large electric reels, heavy tackle is used, which presents the problem of insufficient braking force.
Furthermore, even if sufficient braking force can be obtained, if the rotating shaft rotates when the spool rotates in the direction of winding the fishing line, the braking force will act on the rotating shaft. In particular, when the spool is driven to rotate in the direction of winding the fishing line by the motor, if the braking force acts on the rotating shaft, it puts a load on the motor. This load on the motor can cause problems such as motor failure or increased motor power consumption.
Furthermore, when the cap member, which acts as an adjustment component, rotates in the loosening direction, the screw connection between the adjustment component and the boss portion may come undone, causing the adjustment component to fall off or be lost.

The object of this invention is to provide a fishing reel that, when the spool rotates in the line winding direction, particularly when the spool is rotated in the line winding direction by a motor, can apply sufficient braking force to the spool when releasing the fishing line without influencing the motor with the braking force of the braking structure. Furthermore, the invention aims to provide a fishing reel that prevents the adjustment member from falling off and being lost if the adjustment member is loosened too much.

Regarding a first aspect of the present invention, the fishing reel comprises a reel body, a rotating shaft, and a braking structure. The reel body has a main body portion and a boss portion protruding from the main body portion. The rotating shaft is rotatably supported by the main body portion. At least a portion of the rotating shaft is located inside the boss portion. The braking structure brakes the rotation of the rotating shaft relative to the main body portion.

The braking structure comprises a cylindrical portion, a first friction member, a second friction member, a pressing member, and an adjustment member. The cylindrical portion is positioned inside the boss portion so as to be non-rotatable relative to the boss portion. The first friction member is provided so as to be non-rotatable relative to the cylindrical portion. The second friction member is provided so as to be non-rotatable relative to the rotation axis. The second friction member contacts the first friction member.

The pressing member presses either the first friction member or the second friction member toward the other of the first and second friction members. The adjustment member is provided on the boss portion. The adjustment member adjusts the pressing force of the pressing member.

In the fishing reel relating to the first side, the adjustment member adjusts the pressing force of the first friction member, which is immobile relative to the cylindrical part, and the second friction member, which is immobile relative to the rotating shaft. When the rotating shaft rotates in this state, the first and second friction members slide against each other, generating frictional force. By using this frictional force as a braking force, the rotation of the rotating shaft can be braked with sufficient force. That is, sufficient braking force can be applied to the spool when releasing the fishing line.

Furthermore, the above-mentioned fishing reel can be used with a configuration that prevents the braking force of the braking structure from affecting the motor when the motor rotates the spool in the line winding direction.

Regarding a second aspect of the present invention, in the fishing reel according to the first aspect, the braking structure further comprises a contact friction material. The contact friction material is positioned between a first friction member and a second friction member. The first friction member and the second friction member are in contact via the contact friction material.

In the fishing reel relating to the second aspect, the first friction member and the second friction member are in contact via a contact friction material, thereby enabling the generation of a suitable frictional force between the first and second friction members. This frictional force provides sufficient braking force to the spool when releasing the fishing line.

Regarding a third aspect of the present invention, in the fishing reel according to the second aspect, the contact friction material is integrally provided on at least one of the first friction member and the second friction member.

In the third aspect of the fishing reel, frictional force can be more effectively generated between the first and second frictional members. This frictional force provides sufficient braking force to the spool when releasing the fishing line.

Regarding a fourth aspect of the present invention, a fishing reel according to any one of the first to third aspects further comprises a fixing structure. The fixing structure is used to fix the cylindrical portion to the boss portion. The fixing structure includes a hole provided in the boss portion, a projection provided in the cylindrical portion and inserted through the hole, and a retaining member that restricts the projection from coming out of the hole.

In the fourth aspect of the fishing reel, the fixing structure allows the cylindrical portion to be suitably and non-rotatably fixed inside the boss portion.

Regarding a fifth aspect of the present invention, in a fishing reel relating to any one of the first to fourth aspects, the cylindrical portion has a first engaging portion. The first friction member has a second engaging portion that engages with the first engaging portion in a non-rotatable manner.

In the fishing reel relating to the fifth aspect, the first friction member can be easily mounted in a non-rotatable manner relative to the cylindrical portion by engaging the second engaging portion of the first friction member with the first engaging portion of the cylindrical portion.

Regarding the sixth aspect of the present invention, in a fishing reel relating to any one of the first to fifth aspects, the rotating shaft has a third engaging portion. The second friction member has a fourth engaging portion that engages with the third engaging portion in a non-rotatable manner.

In the fishing reel relating to the sixth aspect, the second friction member can be easily mounted in a non-rotatable manner relative to the rotating shaft by engaging the fourth engaging portion of the second friction member with the third engaging portion of the rotating shaft.

Regarding the seventh aspect of the present invention, in a fishing reel according to any one of the first to sixth aspects, an adjustment member is provided so as to be movable back and forth relative to the boss portion. The adjustment member has an adjustment projection. The adjustment projection adjusts the pressing force applied by a pressing member to either the first friction member or the second friction member toward the other of the first friction member or the second friction member.

In the seventh aspect of the fishing reel, the above-mentioned pressing force can be easily adjusted by the adjustment projection.

Regarding the eighth aspect of the present invention, in a fishing reel relating to any one of the first to seventh aspects, the adjustment member has a first restricting portion. The first restricting portion restricts the movement of the adjustment member relative to the cylindrical portion in the axial direction of the rotation shaft.

In the fishing reel with respect to the eighth side, the first restricting portion of the adjustment member can prevent the adjustment member from coming out of the cylindrical portion. This prevents the adjustment member from falling out and being lost if it is loosened too much.

Regarding the ninth aspect of the present invention, in a fishing reel relating to any one of the first to seventh aspects, the cylindrical portion has a second restricting portion. The second restricting portion restricts the movement of the adjustment member in the axial direction of the rotation shaft.

In the fishing reel with respect to the ninth side, the second restricting portion of the cylindrical section easily prevents the adjustment member from coming out of the cylindrical section. This prevents the adjustment member from falling out and being lost if it is loosened too much.

Regarding the tenth aspect of the present invention, in a fishing reel according to any one of the first to ninth aspects, a plurality of first friction members, spaced apart from each other in the axial direction of the rotating shaft, are configured as a first friction member set. A plurality of second friction members, each individually in contact with the plurality of first friction members, are configured as a second friction member set.

In the fishing reel relating to the tenth aspect, frictional force can be more effectively generated between the first friction member assembly and the second friction member assembly. This frictional force provides sufficient braking force to the spool when releasing the fishing line.

Regarding the eleventh aspect of the present invention, in a fishing reel according to the tenth aspect, the first friction member set includes a pair of first friction members arranged at a distance from each other in the axial direction of the rotation axis. The second friction member set is provided between the pair of first friction members. The second friction member set includes a pair of second friction members that individually contact the pair of first friction members. A pressing member is provided between the pair of second friction members. The pressing member presses the pair of second friction members toward the pair of first friction members.

In the fishing reel relating to the eleventh aspect, frictional force can be more effectively generated between the first friction member assembly and the second friction member assembly.

According to this invention, a fishing reel can be provided with sufficient braking force to the spool when releasing the fishing line. Furthermore, in a fishing reel, if the adjustment member is loosened too much, it is possible to prevent the adjustment member from falling off or being lost.

Hereinafter, an embodiment of an electric reel as a double-bearing reel will be described with reference to the drawings, as an example of a fishing reel according to the present invention. As shown in Figure 1, the electric reel 1 comprises a reel body 3, a handle 5, and a spool 7. As shown in Figure 2, the electric reel 1 further comprises a spool shaft 9 that rotatably supports the spool 7, a first rotation transmission mechanism 11, a second rotation transmission mechanism 12, and a clutch mechanism 13. The electric reel 1 further comprises a braking structure 15 that applies braking force to the rotation of the rotating shaft 10, and a fixing structure 17.

In the following explanation, the axial direction refers to the direction in which the axis X1 of the spool shaft 9 extends, and the direction in which the axis X2 of the rotation shaft 10 extends. The radial direction refers to the radial direction away from the axis X1 of the spool shaft 9, and the radial direction away from the axis X2 of the rotation shaft 10.

The circumferential direction refers to the circumferential direction around the axis X1 of the spool shaft 9 and the circumferential direction around the axis X2 of the rotation shaft 10. The circumferential direction includes the rotational direction of the spool shaft 9 and the rotational direction of the axis X2 of the rotation shaft 10.

As shown in Figure 2, the reel body 3 comprises a first reel body portion 19, a second reel body portion 21, and a connecting portion 23. The first reel body portion 19 and the second reel body portion 21 are spaced apart from each other in the axial direction. The first reel body portion 19 and the second reel body portion 21 are connected to each other via the connecting portion 23.

The first reel body 19 comprises a first side plate 19a and a first cover 19b. The first cover 19b comprises a side cover 19b1 and a boss cover 19b2. The side cover 19b1 covers the first side plate 19a. The side cover 19b1 is attached to the first side plate 19a.

A mechanism housing space S is formed between the side cover 19b1 and the first cover 19b. The boss cover 19b2 is mounted on the side cover 19b1. For example, the boss cover 19b2 is mounted on the outer surface of the side cover 19b1.

The second reel body 21 includes a second side plate 21a, a second cover 21b, and a shaft holding portion 21c. The second side plate 21a is positioned at a distance from the first side plate 19a in the axial direction. The second side plate 21a is connected to the first side plate 19a via a connecting portion 23.

The first side plate 19a, the second side plate 21a, and the connecting portion 23 are integrally formed and constitute the frame of the reel body 3. The second cover 21b covers the second side plate 21a. The second cover 21b is attached to the second side plate 21a.

The shaft holder 21c is positioned axially between the spool 7 and the second cover 21b. The shaft holder 21c is mounted on the second side plate 21a. The shaft holder 21c supports the spool shaft 9 via the bearing 61a.

As shown in Figure 2, the handle 5 is positioned outside the first reel body 19 in the axial direction. The handle 5 is rotatably supported by the reel body 3. For example, the handle 5 is rotatably supported by the first reel body 19. By rotating the handle 5, the spool 7 rotates.

The spool 7 is rotatably mounted on the reel body 3. The spool 7 is positioned axially between the first reel body portion 19 and the second reel body portion 21. The spool 7 is rotatably supported on the spool shaft 9. For example, the spool 7 is attached to the spool shaft 9 via a bearing 61b.

As shown in Figure 2, the spool shaft 9 has an axis X1. The spool shaft 9 is rotatably mounted on the reel body 3. A sun gear 36 of the planetary gear mechanism 33 (described later) is attached to one end of the spool shaft 9. The other end of the spool shaft 9 is rotatably supported by the shaft holder 21c via a bearing 61a.

The rotating shaft 10 has an axis X2. The rotating shaft 10 is positioned adjacent to the spool shaft 9 in the axial direction. The rotating shaft 10 is rotatably supported relative to the reel body 3. In this embodiment, the rotating shaft 10 is rotatably supported relative to the reel body 3 such that its axis X2 is concentric with the axis X1 of the spool shaft 9.

One end of the rotating shaft 10 is positioned inside the boss portion 41, which will be described later. The other end of the rotating shaft 10 is connected to the carrier 37 of the planetary gear mechanism 33, which will be described later, so that it rotates integrally with the carrier 37.

As shown in Figure 2, the first rotation transmission mechanism 11 transmits the rotation of the motor 25 to the spool 7. The first rotation transmission mechanism 11 includes a plurality of gears (not shown). The first rotation transmission mechanism 11 is positioned between the spool 7 and the second cover 21b.

The first rotation transmission mechanism 11 transmits the rotation of the motor 25 to the spool shaft 9 via a plurality of gears (not shown). The rotation of the spool shaft 9 is transmitted from the sun gear 36, located at one end of the spool shaft 9, to the ring gear 34 via a plurality of planetary gears 35 of the planetary gear mechanism 33 (described later). The rotation of the ring gear 34 is transmitted to the spool 7, which rotates integrally with the ring gear 34.

.
Furthermore, when the motor 25 rotates the spool 7 in the winding direction of the fishing line via the first rotation transmission mechanism 11, the spool shaft 9, and the planetary gear mechanism 33, the carrier 37 does not rotate. In other words, the braking structure 15 does not operate. Therefore, the motor 25 can rotate the spool 7 in the winding direction without being affected by the braking force of the braking structure 15.

Motor 25 is used to rotate the spool 7. Motor 25 is positioned in front of the spool 7. It is located between the first cover 19b and the second cover 21b. Motor 25 is connected to the first rotation transmission mechanism 11. The rotation of motor 25 is transmitted to the spool 7 via the first rotation transmission mechanism 11.

As shown in Figure 3, the second rotation transmission mechanism 12 is housed in the mechanism housing space S. The second rotation transmission mechanism 12 transmits the rotation of the handle 5 to the spool 7. For example, the second rotation transmission mechanism 12 includes a drive shaft 27 that rotates integrally with the handle 5, a drive gear 29 that rotates in conjunction with the rotation of the drive shaft 27, a pinion gear 31, and a planetary gear mechanism 33.

As shown in Figure 3, the drive gear 29 is rotatably supported relative to the first reel body 19. For example, the drive gear 29 is rotatably supported relative to the first side plate 19a and the first cover 19b. The drive gear 29 meshes with the pinion gear 31. The rotation of the drive gear 29 is transmitted to the pinion gear 31.

The pinion gear 31 is positioned between the spool 7 and the first cover 19b. For example, the pinion gear 31 is positioned between the planetary gear mechanism 33 and the first cover 19b. The pinion gear 31 is positioned radially outward from the rotating shaft 10. The pinion gear 31 is movable on the outer circumferential surface of the rotating shaft 10 in the axial direction from which the axis X2 of the rotating shaft 10 extends. The pinion gear 31 engages with the carrier 37 of the planetary gear mechanism 33, which will be described later.

As shown in Figure 3, the planetary gear mechanism 33 is positioned between the pinion gear 31 and the spool 7. For example, the planetary gear mechanism 33 is positioned between the flange 7a of the spool 7 and the spool cover 7b in the axial direction. The spool cover 7b is fixed to the outer circumference of the flange 7a of the spool 7.

The spool cover 7b is rotatably supported on the first side plate 19a via a bearing 61c. The spool cover 7b is also rotatably supported on the carrier 37 of the planetary gear mechanism 33 via a bearing 61d.

The planetary gear mechanism 33 is positioned radially outward from one end of the spool shaft 9. The planetary gear mechanism 33 includes a ring gear 34, a plurality of planetary gears 35, a sun gear 36, and a carrier 37. The ring gear 34 is fixed to the outer circumference of the flange 7a of the spool 7. Each of the plurality of planetary gears 35, for example, each of three planetary gears 35, is positioned radially between the ring gear 34 and the sun gear 36. The sun gear 36 is mounted integrally rotatably with respect to the spool shaft 9. The carrier 37 is connected to the spool shaft 9 so as to be rotatable relative to the spool shaft 9. The carrier 37 is connected to the rotating shaft 10 so as to be rotatable integrally with respect to the rotating shaft 10.

The clutch mechanism 13 shown in Figure 3 switches between either the clutch-on state or the clutch-off state, and the other state. The clutch-on state is when the rotation of the handle 5 is transmitted to the spool 7. The clutch-off state is when the rotation of the handle 5 is not transmitted to the spool 7, allowing the spool to rotate freely, for example, when the fishing rig is falling.

In the clutch-engaged state, the pinion gear 31 and the carrier 37 engage, and they rotate integrally with each other. In the clutch-engaged state, the rotation of the pinion gear 31 and the carrier 37 is transmitted to the ring gear 34 and the spool 7 via the three planetary gears 35.

When the pinion gear 31 moves axially away from the spool 7 while the clutch is engaged, the engagement between the pinion gear 31 and the carrier 37 is released. As a result, the rotation of the pinion gear 31 is no longer transmitted to the spool 7 via the planetary gear mechanism 33. This state is the clutch-off state.

The clutch-on and clutch-off states are switched by operating the clutch operating member 38 shown in Figure 1. For example, operating the clutch operating member 38 activates the clutch control mechanism 14 shown in Figure 3, switching between the clutch-on and clutch-off states. Since the configuration of the clutch control mechanism 14 is practically the same as that of the prior art, a detailed explanation is omitted here.

In the electric reel 1 having the above configuration, as shown in Figure 2, the reel body 3 further has a boss portion 41. More specifically, the reel body 3 has a first reel body portion 19, a second reel body portion 21, a connecting portion 23, and a boss portion 41. The first reel body portion 19, the second reel body portion 21, and the connecting portion 23 are examples of body portions.

The boss portion 41 is provided on the first reel body portion 19. For example, the boss portion 41 is provided on the first cover 19b. More specifically, the boss portion 41 protrudes from the side cover 19b1. The boss portion 41 is formed integrally with the side cover 19b1. The boss portion 41 passes through the hole 19b3 of the boss cover 19b2 and is positioned axially outward from the outer surface of the boss cover 19b2.

As shown in Figures 4, 5A, and 5B, at least a portion of the rotating shaft 10 is positioned on the boss portion 41. For example, the other end of the rotating shaft 10 is positioned on the boss portion 41. The boss portion 41 has a boss body 41a, a male threaded portion 41b, a bottom wall 41c as shown in Figure 5A, and a pair of through holes 41d as shown in Figure 5A.

As shown in Figures 5A and 5B, the male screw portion 41b is formed on the outer circumferential surface of the boss body 41a. The bottom wall 41c is provided for arranging the braking structure 15. The bottom wall 41c is formed to face the adjustment member 53, which will be described later, in the axial direction.

The bottom wall 41c is formed on the inner circumferential surface of the boss body 41a. A hole 41e for inserting the rotating shaft 10 is formed in the bottom wall 41c. The rotating shaft 10 is supported on the inner circumferential surface of the hole 41e via a bearing member 42. A pair of through holes 41d are provided in the bottom wall 41c. As shown in Figure 5A, the pair of through holes 41d penetrate the bottom wall 41c. The pair of through holes 41d constitute the fixing structure 17.

The braking structure 15 shown in Figure 4 brakes the rotation of the rotating shaft 10 relative to the reel body 3. For example, the braking structure 15 brakes the rotation of the rotating shaft 10 relative to the boss portion 41.

As shown in Figures 4, 5A, and 5B, the braking structure 15 comprises a cylindrical portion 43, a first friction member assembly 45, a second friction member assembly 47, contact friction materials 49a and 49b, a pressing member 51, and an adjustment member 53.

As shown in Figure 5A, the cylindrical portion 43 is positioned inside the boss portion 41 so as to be non-rotatable relative to the boss portion 41. The cylindrical portion 43 has a bottomed cylindrical portion 43a, a pair of slits 43b, a flange portion 43c, a retaining projection 43d, and a protruding portion 43e.

As shown in Figures 5A and 5B, the bottomed cylindrical portion 43a is formed in a bottomed cylindrical shape. A hole for inserting the rotating shaft is formed in the bottomed cylindrical portion 43a. As shown in Figure 5A, a pair of slits 43b are provided in the bottomed cylindrical portion 43a. The pair of slits 43b extend axially in the wall portion of the bottomed cylindrical portion 43a. The pair of slits 43b is an example of a first engaging portion.

As shown in Figures 5A and 5B, the flange portion 43c protrudes radially outward from the wall of the closed-bottom cylindrical portion 43a on the opening side of the closed-bottom cylindrical portion 43a. The flange portion 43c abuts against the tip of the boss portion 41. An O-ring 48 is positioned radially between the flange portion 43c and the adjustment member 53.

The retaining projection 43d restricts the axial movement of the adjustment member 53. The retaining projection 43d is provided on the inner circumferential surface of the closed-end cylindrical portion 43a. On the opening side of the closed-end cylindrical portion 43a, the retaining projection 43d protrudes radially inward from the inner circumferential surface of the closed-end cylindrical portion 43a. The retaining projection 43d is an example of a second restricting portion.

The projection 43e includes a pair of projections 43e. The pair of projections 43e are provided on the bottomed cylindrical portion 43a. For example, the pair of projections 43e project axially from the bottom of the bottomed cylindrical portion 43a. The pair of projections 43e are inserted into a pair of through holes 41d. This ensures that the cylindrical portion 43 is non-rotatable relative to the boss portion 41. The pair of projections 43e constitute the fixing structure 17.

As shown in Figure 4, the first friction member assembly 45 includes a plurality of first friction members 45a and 45b. In this embodiment, the first friction member assembly 45 includes a pair of first friction members 45a and 45b. As shown in Figure 5A, the pair of first friction members 45a and 45b are mounted non-rotatably on the cylindrical portion 43. The pair of first friction members 45a and 45b are spaced apart from each other in the axial direction.

As shown in Figures 5A and 5B, each of the pair of first friction members 45a and 45b has a first body 45c1, a pair of engaging protrusions 45c2, and a first hole 45c3. The first body 45c1 is formed in a circular plate shape.

As shown in Figures 4 and 5A, a pair of engaging projections 45c2 protrude radially outward from the outer circumference of the first body 45c1. As shown in Figure 5A, the pair of engaging projections 45c2 engage non-rotatably with a pair of slits 43b. The pair of engaging projections 45c2 is an example of a second engaging portion. As shown in Figures 5A and 5B, the first hole 45c3 penetrates the first body 45c1. The rotating shaft 10 is inserted through the first hole 45c3.

As shown in Figure 4, the second friction member assembly 47 includes a plurality of second friction members 47a and 47b. In this embodiment, the second friction member assembly 47 includes a pair of second friction members 47a and 47b. As shown in Figures 5A and 5B, the pair of second friction members 47a and 47b are mounted so as to be non-rotatable with respect to the rotation axis 10. The pair of second friction members 47a and 47b are spaced apart from each other in the axial direction.

As shown in Figures 5A and 5B, a pair of second friction members 47a and 47b are positioned between a pair of first friction members 45a and 45b. Each of the second friction members 47a and 47b contacts the first friction members 45a and 45b individually. More specifically, each of the second friction members 47a and 47b contacts each of the first friction members 45a and 45b via contact friction materials 49a and 49b.

As shown in Figures 5A and 5B, each of the pair of second friction members 47a and 47b has a second body 47c1 and a second hole 47c2. The second body 47c1 is formed in a circular plate shape. The second hole 47c2 penetrates the second body 47c1. The inner circumferential surface of the second hole 47c2 is formed in a non-circular shape.

The rotating shaft 10 is inserted through the second hole 47c2. The second hole 47c2 engages with the engaging portion 10a of the rotating shaft 10 in a non-rotatable manner. The engaging portion 10a has a non-circular outer surface. The second hole 47c2 is an example of a fourth engaging portion. The engaging portion 10a is an example of a third engaging portion.

As shown in Figures 4, 5A, and 5B, the contact friction materials 49a and 49b are positioned between the first friction members 45a and 45b and the second friction members 47a and 47b. The contact friction materials 49a and 49b are integrally provided on at least one of the first friction members 45a and 45b and the second friction members 47a and 47b.

In this embodiment, the contact friction materials 49a and 49b are provided on each of the pair of first friction members 45a and 45b. More specifically, the contact friction materials 49a and 49b are attached to each of the pair of first friction members 45a and 45b. The contact friction materials 49a and 49b may also be attached to each of the pair of second friction members 47a and 47b. The contact friction materials 49a and 49b are preferably friction materials such as carbon and felt.

In this embodiment, an example is shown in which the contact friction materials 49a and 49b are arranged between the first friction members 45a and 45b and the second friction members 47a and 47b. In this case, the first friction members 45a and 45b and the second friction members 47a and 47b are in contact via the contact friction materials 49a and 49b. Alternatively, the first friction members 45a and 45b and the second friction members 47a and 47b may be brought into direct contact without using the contact friction materials 49a and 49b.

The tip of the rotating shaft 10 is fitted with a first friction member assembly 45, a second friction member assembly 47, contact friction materials 49a and 49b, and a C-ring 53f for preventing the pressing member 51 from coming off.

As shown in Figure 4, the pressing member 51 includes a pair of pressing members 51a and 51b. The pair of pressing members 51a and 51b press either one of the first friction members 45a and 45b, or the second friction members 47a and 47b, toward the other of the first friction members 45a and 45b, or the second friction members 47a and 47b.

In this embodiment, as shown in Figures 5A and 5B, the pressing member 51 presses the second friction members 47a and 47b toward the first friction members 45a and 45b. A pair of pressing members 51a and 51b are provided between the pair of second friction members 47a and 47b on the radially outer side of the rotation axis 10. For example, each of the pair of pressing members 51a and 51b is a disc spring.

A washer 51c is placed between a pair of pressing members 51a and 51b. Each of the pressing members 51a and 51b is positioned in a compressed state between the washer 51c and the pair of second friction members 47a and 47b. As a result, the pair of second friction members 47a and 47b are individually pressed by the pair of pressing members 51a and 51b towards the pair of first friction members 45a and 45b.

The adjustment member 53 shown in Figure 4 is used to adjust the pressing force of the pressing member 51. As shown in Figures 5A and 5B, the adjustment member 53 is provided on the boss portion 41. The adjustment member 53 is provided so as to be able to move back and forth relative to the boss portion 41.

As shown in Figures 5A and 5B, the adjustment member 53 has a knob portion 53a, a female threaded portion 53b, an adjustment projection 53c, and a retaining ring 53d. The knob portion 53a is formed in a bottomed cylindrical shape. The female threaded portion 53b is formed on the inner circumferential surface of the knob portion 53a. The female threaded portion 53b is screwed into the male threaded portion 41b of the boss portion 41.

The adjustment projection 53c adjusts the pressing force applied by the pressing member 51 to either the first friction members 45a, 45b or the second friction members 47a, 47b toward the other of the first friction members 45a, 45b or the second friction members 47a, 47b. In this embodiment, the adjustment projection 53c adjusts the pressing force applied by the pressing member 51 to the second friction members 47a, 47b toward the first friction members 45a, 45b.

The adjustment projection 53c protrudes from the bottom of the knob portion 53a. The adjustment projection 53c is formed in a cylindrical shape. The adjustment projection 53c presses against the first friction member 45a. More specifically, the adjustment projection 53c presses against the first friction member 45a via a washer 53e. A cylindrical portion 43 is positioned radially between the adjustment projection 53c and the boss portion 41.

As shown in Figures 5A and 5B, the retaining ring 53d restricts the axial movement of the adjustment member 53 relative to the cylindrical portion 43. The retaining ring 53d is mounted on the tip of the adjustment projection 53c. More specifically, the retaining ring 53d is mounted on the tip of the adjustment projection 53c such that it protrudes radially outward from the outer circumferential surface of the adjustment projection 53c.

As shown in Figure 5B, when the adjustment member 53 moves away from the spool, the retaining ring 53d abuts against the anti-dislodgement projection 43d of the cylindrical portion 43, thereby preventing the adjustment member 53 from coming off the cylindrical portion 43. The retaining ring 53d is an example of the first regulating portion.

The fixing structure 17 shown in Figure 5A is used to fix the cylindrical portion 43 to the boss portion 41. The fixing structure 17 has a pair of protrusions 43e, a pair of through holes 41d, and a pair of retaining members 55. The pair of protrusions 43e are provided on the cylindrical portion 43 as described above. The pair of through holes 41d are provided on the boss portion 41 as described above.

As shown in Figure 5A, the pair of retaining members 55 individually restrict the dislodgement of the pair of protrusions 43e from the pair of through holes 41d. For example, the pair of retaining members 55 are push nuts. When the pair of protrusions 43e are inserted through the pair of through holes 41d, the pair of retaining members 55 are individually attached to the tips of the pair of protrusions 43e.

The braking structure 15 having the above configuration operates as follows: The angler adjusts the pressing force of the braking structure 15 by rotating the adjustment member 53. When the angler sets the clutch mechanism 13 to the clutch-off state and the fishing line is released, the spool 7 rotates. The rotation of the spool 7 is transmitted to the carrier 37 via the ring gear 34 and the multiple planetary gears 35. The rotating shaft 10 rotates together with the carrier 37.

The pair of second friction members 47a and 47b rotate together with the rotating shaft 10 and slide against the contact friction materials 49a and 49b of the pair of first friction members 45a and 45b. This brakes the rotation of the rotating shaft 10.

In the electric reel 1 according to this embodiment, the adjustment member 53 adjusts the pressing force between the first friction members 45a and 45b, which are immobile relative to the cylindrical portion 43, and the second friction members 47a and 47b, which are immobile relative to the rotating shaft 10. When the rotating shaft 10 rotates in this state, the first friction members 45a and 45b and the second friction members 47a and 47b slide against each other, generating frictional force. By using this frictional force as a braking force, the rotation of the rotating shaft 10 can be braked with sufficient force. That is, sufficient braking force can be applied to the spool 7 when releasing the fishing line.

In the electric reel 1, when the motor 25 rotates the spool 7 in the winding direction, the rotation of the motor 25 is transmitted to the spool 7 via the first rotation transmission mechanism 11, the spool shaft 9, and the planetary gear mechanism 33. In this case, the carrier 37 of the planetary gear mechanism 33 does not rotate. Therefore, the motor 25 can rotate the spool 7 in the winding direction without being affected by the braking force of the braking structure 15.

In the electric reel 1, the first friction members 45a, 45b and the second friction members 47a, 47b are in contact via the contact friction material 49a, 49b. Therefore, frictional force can be more effectively generated between the first friction members 45a, 45b and the second friction members 47a, 47b. This frictional force provides sufficient braking force to the spool 7 when releasing the fishing line.

In the electric reel 1, contact friction materials 49a and 49b are integrally provided on at least one of the first friction members 45a and 45b and the second friction members 47a and 47b. Specifically, the contact friction materials 49a and 49b are integrally provided on the first friction members 45a and 45b. This allows for a more favorable generation of frictional force between the first friction members 45a and 45b and the second friction members 47a and 47b. This frictional force provides sufficient braking force to the spool 7 when releasing the fishing line.

In the electric reel 1, the fixing structure 17 allows the cylindrical portion 43 to be suitably fixed inside the boss portion 41 in a way that prevents rotation.

In the electric reel 1, the engaging projections 45c2 of the first friction members 45a and 45b can be engaged with the slit 43b of the cylindrical portion 43, thereby easily preventing rotation of the first friction members 45a and 45b relative to the cylindrical portion 43.

In the electric reel 1, the second friction members 47a and 47b can be easily mounted in a non-rotatable manner relative to the rotating shaft 10 by engaging the second holes 47c2 of the second friction members 47a and 47b with the engaging portion 10a of the rotating shaft 10.

In the electric reel 1, by providing an adjustment projection 53c on the knob portion 53a of the adjustment member 53, the pressing force applied by the second friction members 47a and 47b against the first friction members 45a and 45b can be easily adjusted.

In the electric reel 1, the retaining ring 53d of the adjustment member 53 and the anti-dislodgement projection 43d of the cylindrical portion 43 easily restrict the adjustment member 53 from coming out of the cylindrical portion 43. This prevents the adjustment member 53 from falling out or being lost if it is loosened too much.

In the electric reel 1, the friction force can be more effectively generated by the first friction member set 45, which includes multiple first friction members 45a and 45b, and the second friction member set 47, which includes multiple second friction members 47a and 47b. This friction force provides sufficient braking force to the spool 7 when releasing the fishing line.

(Variation 1)
In the above embodiment, as shown in Figure 5B, the retaining ring 53d of the adjustment member 53 and the anti-dislodgement projection 43d of the cylindrical portion 43 prevent the adjustment member 53 from coming out of the cylindrical portion 43.

As shown in Figure 6, the disengagement of the adjustment member 53 from the cylindrical portion 43 can also be achieved by the following configuration. The adjustment member 53 has a knob portion 53a, a female screw portion 53b, an adjustment projection 53c, and a flange portion 53g. The configurations of the knob portion 53a, the female screw portion 53b, and the adjustment projection 53c are the same as in the above embodiment.

The flange portion 53g is integrally formed with the tip of the adjustment projection 53c. More specifically, the flange portion 53g is integrally formed with the tip of the adjustment projection 53c so as to protrude radially outward from the outer circumferential surface of the adjustment projection 53c. The flange portion 53g is an example of a first restricting portion. In this way, even if the retaining ring 53d of the above embodiment is changed to the flange portion 53g, it is possible to restrict the adjustment member 53 from coming out of the cylindrical portion 43.
(Variation 2)
In the above embodiment, as shown in Figure 5A, the cylindrical portion 43 is positioned inside the boss portion 41 so as to be non-rotatable relative to the boss portion 41. In contrast, the cylindrical portion 43 may be integrally formed on the inner circumferential surface of the boss portion 41.
