Abstract

The invention provides a dual-bearing reel capable of smoothly moving a pinion gear. A dual-bearing reel (100) is provided with a reel body (2), a spool (3), a spool shaft (4), a handle (5), a pinion gear (15), a clutch control mechanism (22), and bearings (16a, 16b). The pinion gear (15) moves between a transmission position at which the rotational force of the handle (5) is transmitted to the spool shaft (4) and a blocking position at which the transmission of the rotational force of the handle (5) to the spool shaft (4) is blocked. The bearings (16a, 16b) support the pinion gear (15) so that the pinion gear (15) can rotate with respect to the reel body (2). When the pinion gear (15) moves between the transmission position and the blocking position, the bearings (16a, 16b) move together with the pinion gear (15).

[0005] Patent document 1: Japanese Patent No. 7257488. Summary of the Invention

[0006] The problem that the invention aims to solve

[0007] In conventional dual-bearing cable reels, the pinion is supported by a bearing in a rotatable manner. In this case, the outer ring of the bearing is mounted on the cable reel body. In this state, if the clutch control mechanism is engaged, the pinion moves relative to the inner ring of the bearing between a transmission position and a blocking position.

[0008] In this structure, if electrolyzed water, such as brine, seeps between the inner ring of the bearing and the outer circumferential surface of the pinion, both the inner ring and the outer circumferential surface of the pinion may oxidize due to electrolysis. In this case, with oxidation of both surfaces, the outer circumferential surface of the pinion and the inner ring of the bearing may become firmly bonded together. Under these circumstances, it becomes difficult for the pinion to move smoothly axially relative to the inner ring of the bearing.

[0009] The purpose of this invention is to provide a double-bearing cable reel that enables smooth movement of the pinion.

[0010] means for solving problems

[0011] Regarding a first aspect of the invention, a dual-bearing cable reel includes a cable reel body, a handle, a reel shaft, a drum, a pinion, a clutch control mechanism, and bearings. The handle is rotatably supported on the cable reel body. The reel shaft is rotatably supported on the cable reel body. The drum and the reel shaft rotate integrally.

[0012] The pinion gear can move between a position that transmits rotational force to the spool shaft and a position that blocks the transmission of rotational force to the spool shaft. A clutch control mechanism moves the pinion gear between these two positions. A bearing supports the pinion gear in a manner that allows it to rotate relative to the winding reel body. The bearing moves along with the pinion gear as it moves between these positions.

[0013] In the first aspect of the dual-bearing reel, when the pinion moves between the transmission position and the blocking position, the bearing moves together with the pinion, thus eliminating the need for a gap between the inner ring of the bearing and the outer circumferential surface of the pinion. Therefore, it is possible to prevent electrolyzed water from seeping between the inner ring of the bearing and the outer circumferential surface of the pinion. That is, in this invention, it is possible to prevent the outer circumferential surface of the pinion from becoming stuck to the inner ring of the bearing. This allows the pinion to move smoothly.

[0014] The dual-bearing cable reel according to a second aspect of the first aspect of the present invention further includes a sliding portion. The sliding portion is disposed between the cable reel body and the bearing.

[0015] In the second aspect of the double-bearing reel, the sliding part is disposed between the reel body and the bearing, thus enabling the bearing and the pinion to move smoothly together.

[0016] The dual-bearing reel according to the first, second, or third aspect of the present invention further includes a force-applying part. When the bearing moves together with the pinion, the force-applying part applies force to the bearing.

[0017] In the third aspect of the double-bearing reel, the force-applying part applies force to the bearing, thus enabling the bearing and pinion to move more smoothly together.

[0018] The double-bearing cable reel according to any one of the first to third aspects of the present invention further comprises a waterproof portion. The waterproof portion is provided on the pinion to prevent water from seeping into the bearing.

[0019] In the fourth aspect of the double-bearing reel, a waterproof section prevents water from seeping into the bearing. This ensures smooth bearing rotation.

[0020] The double-bearing cable reel according to any one of the first to fourth aspects of the present invention is configured as follows: The bearing has an inner ring, an outer ring, and rolling elements. The inner ring is supported by a pinion. When the pinion moves between a transmission position and a stop position, the outer ring is supported on the cable reel body in a manner that allows it to slide relative to the cable reel body. The rolling elements are disposed between the inner and outer rings. The rolling elements support the inner and outer rings in a manner that allows them to rotate relative to each other.

[0021] The double-bearing cable reel according to the fifth and sixth aspects of the present invention further includes a sliding portion. The sliding portion is disposed between the cable reel body and the outer ring of the bearing.

[0022] In the sixth aspect of the double-bearing reel, the sliding part is disposed between the reel body and the outer ring of the bearing, thus enabling the bearing and the pinion to move smoothly together.

[0023] The seventh aspect of the double-bearing cable reel according to any one of the first to sixth aspects of the invention further includes a force-applying part. When the bearing moves together with the pinion, the force-applying part applies force to the outer ring of the bearing in a direction from the blocking position toward the transmission position.

[0024] In the seventh aspect of the double-bearing winding machine, the force-applying part applies force to the outer ring of the bearing in the aforementioned direction, thereby enabling the bearing and the pinion to move more smoothly together.

[0025] The double-bearing reel according to the eighth aspect of any one of the first to seventh aspects of the invention is configured as follows: The pinion has a gear portion and a transmission portion. When in the transmission position, the rotational force of the handle is transmitted to the gear portion. When in the transmission position, the transmission portion transmits the rotation of the pinion to the reel shaft. The bearing includes a first bearing disposed at a first end of the pinion on the gear portion side.

[0026] In the double-bearing winding mechanism of the eighth aspect, the following effect is achieved: Normally, when the clutch is engaged, an external force from the main gear acts on the gear section of the pinion. Therefore, the smaller the axial distance between the gear section of the pinion and the first bearing, the more stably the pinion can rotate.

[0027] However, in the prior art, when the pinion is in the transmission position, the gear portion of the pinion is axially away from the first bearing, so the rotational stability of the pinion may be reduced.

[0028] In contrast, in this dual-bearing reel, the first bearing is located at the first end of the pinion on the gear section side. Therefore, the first bearing moves axially together with the pinion in a state adjacent to the gear section. As a result, the pinion can rotate stably when it is in the transmission position.

[0029] The double-bearing reel according to the ninth aspect of any one of the first to eighth aspects of the present invention is configured as follows: The pinion has a gear portion and a transmission portion. When in the transmission position, the rotational force of the handle is transmitted to the gear portion. When in the transmission position, the transmission portion transmits the rotation of the pinion to the reel shaft. The bearing includes a second bearing disposed at a second end of the pinion on the transmission portion side.

[0030] In the ninth aspect of the double-bearing winding device, the second bearing is provided at the second end of the pinion on the transmission section side, so that the pinion can be rotated stably by means of the first bearing and the second bearing. Attached Figure Description

[0038] like Figure 1 and Figure 2 As shown, a dual-bearing cable reel 100 according to one embodiment of the present invention includes a cable reel body 2, a drum 3, a drum shaft 4, a handle 5, a rotation transmission mechanism 10, a clutch mechanism 20, and a clutch control mechanism 22. It should be noted that... Figure 1 This is a side view of the reel body 2 as seen from the handle 5 side.

[0039] It should be noted that in the following description, the direction in which the fishing line is wound out during fishing is defined as forward, and the opposite direction is defined as backward. Left and right directions are the left and right directions when viewing the dual-bearing reel 100 from the rear. Furthermore, the extension direction of the reel shaft 4 is defined as axial. The direction orthogonal to the extension direction of the reel shaft 4 is defined as radial. The direction around the reel shaft 4 is defined as circumferential.

[0040] like Figure 2 As shown, the cable reel body 2 has a frame 6, a first side cover 7, and a second side cover 8. The frame 6 has a first side plate 6a, a second side plate 6b, and a plurality of connecting portions 6c. The first side plate 6a is disposed on the right side of the frame 6. The first side plate 6a has a first protrusion portion 6d.

[0041] The second side plate 6b is axially spaced from the first side plate 6a on the left side of the frame 6. A plurality of connecting portions 6c extend axially and connect the first side plate 6a and the second side plate 6b. A first side cover 7 covers the right side of the first side plate 6a of the frame 6. The first side cover 7 has a second protrusion 7a. The second protrusion 7a protrudes axially from the outer surface of the first side cover 7. A second side cover 8 covers the left side of the second side plate 6b of the frame 6.

[0042] like Figure 2 As shown, the drum 3 is disposed between the first side plate 6a and the second side plate 6b. The drum 3 is connected to the drum shaft 4 in a manner that allows it to rotate integrally with the drum shaft 4. The drum 3 is supported on the winding machine body 2 via the drum shaft 4 in a manner that allows it to rotate relative to the winding machine body 2. The drum shaft 4 extends axially inside the winding machine body 2. The drum shaft 4 is supported on the winding machine body 2 in a rotatable manner by bearings 11a, 11b, and 11c provided on the winding machine body 2.

[0043] like Figure 3 As shown, the drum shaft 4 has a first shaft portion 4a, a second shaft portion 4b, and a third shaft portion 4c. The first shaft portion 4a extends axially within the first side outer cover 7 (see reference). Figure 2 The diameter of the second shaft portion 4b is larger than the outer diameter of the first shaft portion 4a, and it is formed adjacent to the first shaft portion 4a. The diameter of the third shaft portion 4c is larger than the outer diameter of the second shaft portion 4b, and it is formed adjacent to the second shaft portion 4b.

[0044] A locking pin 4d is fixed to the third shaft portion 4c. The locking pin 4d passes radially through the third shaft portion 4c. Both ends of the third shaft portion 4c protrude radially from the outer circumferential surface of the drum shaft 4. The locking pin 4d constitutes the structure of the clutch mechanism 20.

[0045] like Figure 1 As shown, the handle 5 is rotatable relative to the cable reel body 2 and is rotatably supported on the cable reel body 2. The rotation of the handle 5 is transmitted to the drive gear 14 via the drive shaft 13. Figure 2 As shown, the rotary transmission mechanism 10 transmits the rotation of the handle 5 to the drum 3. The rotary transmission mechanism 10 has a drive shaft 13, a drive gear 14, and a pinion 15.

[0046] like Figure 2 As shown, the drive shaft 13 is connected to the handle 5 in a manner that allows it to rotate integrally with the handle 5. The drive shaft 13 rotates only in the winding direction via a one-way clutch (not shown) disposed on the outer periphery of the drive shaft 13. The drive gear 14 is mounted on the drive shaft 13. The rotation of the handle 5 is transmitted to the drive gear 14 via a drag mechanism (not shown) disposed within the first side cover 7.

[0047] like Figure 4A and Figure 4B As shown, the pinion 15 can transmit the rotational force of the handle 5 to the drum shaft 4 at the position (refer to...) Figure 4A ) and the blocking position for blocking the transmission of rotational force from handle 5 to drum shaft 4 (refer to Figure 4B Move between ).

[0048] Figure 4A The diagram shows the pinion 15 in the transmission position. In the transmission position, the pinion 15 is connected to the drum shaft 4 in a manner that allows it to rotate integrally with the drum shaft 4. This state is the transmission state in which the rotational force of the handle 5 is transmitted to the drum 3. The transmission state is the state in which the clutch mechanism 20, described later, is engaged.

[0049] Figure 4B This diagram shows the pinion 15 in the blocked position. In the blocked position, the connection between the pinion 15 and the drum shaft 4 is disengaged. This state is the blocked state, where the rotational force of the handle 5 is not transmitted to the drum 3. The blocked state is the state where the clutch mechanism 20 is disengaged.

[0050] like Figure 2 As shown, pinion 15 meshes with drive gear 14. The rotation axis X of pinion 15 is concentric with the rotation axis of drum shaft 4. Figure 3 As shown, the pinion 15 has a cylindrical main body 15a, a gear part 15b, and a transmission part 15c.

[0051] The main body 15a is cylindrical, and a roller shaft 4 is disposed on the inner circumference of the main body 15a. A through hole 15a1 is formed on the inner circumferential surface of the main body 15a. The through hole 15a1 is a hole that extends through along the axial direction.

[0052] like Figure 3 As shown, the through hole 15a1 has a large-diameter hole portion 15a2 and a small-diameter hole portion 15a3. The inner diameter of the large-diameter hole portion 15a2 is larger than the outer diameter of the third shaft portion 4c of the drum shaft 4. When the pinion 15 is in the transmission position, the end of the third shaft portion 4c is positioned in the large-diameter hole portion 15a2.

[0053] The small-diameter bore 15a3 is disposed adjacent to the large-diameter bore 15a2. The inner diameter of the small-diameter bore 15a3 is smaller than the outer diameter of the third shaft portion 4c of the drum shaft 4. In addition, the inner diameter of the small-diameter bore 15a3 is larger than the outer diameter of the first shaft portion 4a and the second shaft portion 4b of the drum shaft 4. When the pinion 15 is in the transmission position, the first shaft portion 4a and the second shaft portion 4b of the drum shaft 4 are disposed in the small-diameter bore 15a3.

[0054] When pinion 15 is in the transmission position, the rotational force of handle 5 is transmitted to... Figure 3 The gear section 15b is shown. In detail, as... Figure 2As shown, when the pinion 15 is in the transmission position, the gear part 15b meshes with the drive gear 14, transmitting the rotational force of the handle 5 to the gear part 15b.

[0055] like Figure 3 As shown, the gear portion 15b is disposed on the outer periphery of the main body portion 15a. The gear portion 15b is disposed between the first end portion 15d and the second end portion 15e of the main body portion 15a. The first end portion 15d is the portion that protrudes axially from the gear portion 15b toward the handle 5 side (an example of the first end portion on the gear portion side). The second end portion 15e is the end portion opposite to the first end portion 15d (an example of the second end portion on the transmission portion side).

[0056] like Figure 3 As shown, when the pinion 15 is in the transmission position, the transmission part 15c transmits the rotation of the pinion 15 to the drum shaft 4. The transmission part 15c is axially spaced from the gear part 15b, forming the second end portion 15e of the main body part 15a. The transmission part 15c has an engaging recess 15f. In this embodiment, the engaging recess 15f includes a pair of engaging recesses 15f.

[0057] like Figure 3 As shown, a pair of engaging recesses 15f are provided on the end face of the second end 15e, for example, on the end face of the transmission part 15c. The pair of engaging recesses 15f are each arranged radially opposite to each other, formed in a manner that recesses axially from the end face of the transmission part 15c. When the pinion 15 is in the transmission position, the pair of engaging recesses 15f engage with the engaging pin 4d. The pair of engaging recesses 15f are part of the structure of the clutch mechanism 20. Figure 2 The clutch control mechanism 22 shown engages with the recess 15g located between the gear section 15b and the transmission section 15c.

[0058] like Figure 3 As shown, the pinion 15 is rotatably supported by a first bearing 16a and a second bearing 16b. The first bearing 16a and the second bearing 16b support the pinion 15 in a manner that allows the pinion 15 to rotate relative to the cable reel body 2. Figure 4A and Figure 4B As shown, when the pinion 15 moves between the transmission position and the blocking position, the first bearing 16a and the second bearing 16b move together with the pinion 15.

[0059] like Figure 3 As shown, a first bearing 16a is disposed at the first end 15d of the pinion 15. Specifically, the first bearing 16a is axially adjacent to the gear portion 15b. The first bearing 16a is disposed on the outer peripheral surface of the first end 15d in a manner that allows it to move axially integrally with the pinion 15.

[0060] like Figure 4A and Figure 4B As shown, the first bearing 16a is radially disposed between the first end 15d of the pinion 15 and the winding reel body 2. More specifically, the first bearing 16a is radially disposed between the first end 15d of the pinion 15 and the second protrusion 7a of the first side cover 7.

[0061] like Figure 3 As shown, the first bearing 16a has a first inner ring 16a1, a first outer ring 16a2, and a first rolling element 16a3. The first inner ring 16a1 is supported on the pinion 15. Specifically, the first inner ring 16a1 is disposed on the outer peripheral surface of the first end 15d of the pinion 15. The first inner ring 16a1 is axially adjacent to the gear portion 15b. A positioning member 17 is disposed axially between the first inner ring 16a1 and the gear portion 15b.

[0062] like Figure 3 As shown, the first inner ring 16a1 is prevented from disengaging by an anti-disengagement component 18. In this embodiment, the anti-disengagement component 18 is a C-shaped retaining ring. The anti-disengagement component 18 is disposed on an annular recess 15d1 provided on the outer peripheral surface of the first end 15d of the pinion 15. This structure restricts the first bearing 16a from disengaging from the first end 15d of the pinion 15.

[0063] like Figure 4A and Figure 4B As shown, the first outer ring 16a2 is positioned radially inward from the inner circumferential surface of the second protrusion 7a of the first side cover 7. When the pinion 15 moves between the transmission position and the blocking position, the first outer ring 16a2 is supported on the cable reel body 2 in a manner that allows it to slide relative to the cable reel body 2. In this embodiment, the first outer ring 16a2 is supported on the cable reel body 2 in a manner that allows it to slide relative to the cable reel body 2 via the first sliding portion 23 described later.

[0064] like Figure 3 As shown, a first rolling element 16a3 is disposed between a first inner ring 16a1 and a first outer ring 16a2. The first rolling element 16a3 supports the inner ring 16a1 and the first outer ring 16a2 in a manner that allows the first inner ring 16a1 and the first outer ring 16a2 to rotate relative to each other.

[0065] like Figure 3 As shown, the second bearing 16b is disposed at the second end 15e of the pinion 15. The second bearing 16b is disposed on the outer peripheral surface of the second end 15e in such a way that it can move axially integrally with the pinion 15.

[0066] like Figure 4A and Figure 4BAs shown, the second bearing 16b is radially disposed between the second end 15e of the pinion 15 and the winding reel body 2. More specifically, the second bearing 16b is radially disposed between the second end 15e of the pinion 15 and the first boss portion 6d of the first side plate 6a.

[0067] like Figure 3 As shown, the second bearing 16b has a second inner ring 16b1, a second outer ring 16b2, and a second rolling element 16b3. The second inner ring 16b1 is supported on the pinion 15. Specifically, the second inner ring 16b1 is pressed into and fixed to the outer circumferential surface of the second end 15e of the pinion 15. The fixing configuration of the second inner ring 16b1 can also be other configurations.

[0068] like Figure 4A and Figure 4B As shown, the second outer ring 16b2 is positioned radially inward from the inner circumferential surface of the first protrusion 6d of the first side plate 6a. When the pinion 15 moves between the transmission position and the blocking position, the second outer ring 16b2 is supported on the cable reel body 2 in a manner that allows it to slide relative to the cable reel body 2. In this embodiment, the second outer ring 16b2 is supported on the cable reel body 2 in a manner that allows it to slide relative to the cable reel body 2 via the second sliding portion 24 described later.

[0069] like Figure 3 As shown, the second rolling element 16b3 is disposed between the second inner ring 16b1 and the second outer ring 16b2. The second rolling element 16b3 supports the second inner ring 16b1 and the second outer ring 16b2 in a manner that allows the second inner ring 16b1 and the second outer ring 16b2 to rotate relative to each other.

[0070] like Figure 4A and Figure 4B As shown, a first sliding portion 23 is disposed between the first bearing 16a and the winding reel body 2. The first sliding portion 23 is formed in a cylindrical shape. The first sliding portion 23 is preferably a resin-made collar component. The first sliding portion 23 is radially disposed between the first outer ring 16a2 of the first bearing 16a and the winding reel body 2.

[0071] In detail, the first sliding portion 23 is radially disposed between the first outer ring 16a2 of the first bearing 16a and the inner peripheral surface of the second protrusion 7a of the first side cover 7. The first sliding portion 23 is fixed to the inner peripheral surface of the second protrusion 7a of the first side cover 7 by elastic engagement. The fixing configuration of the first sliding portion 23 can also be other fixing configurations. The inner peripheral surface of the first sliding portion 23 is in contact with the outer peripheral surface of the first outer ring 16a2 of the first bearing 16a.

[0072] like Figure 4A and Figure 4BAs shown, a second sliding portion 24 is disposed between the second bearing 16b and the winding reel body. The second sliding portion 24 is formed in a cylindrical shape. The second sliding portion 24 is preferably a resin-made collar component. The second sliding portion 24 is radially disposed between the second outer ring 16b2 of the second bearing 16b and the winding reel body 2.

[0073] In detail, the second sliding portion 24 is radially disposed between the second outer ring 16b2 of the second bearing 16b and the inner peripheral surface of the first boss portion 6d of the first side plate 6a. The second sliding portion 24 is pressed into and fixed to the inner peripheral surface of the first boss portion 6d of the first side plate 6a. The fixing configuration of the second sliding portion 24 can also be other fixing configurations. The outer peripheral surface of the second outer ring 16b2 of the second bearing 16b contacts the inner peripheral surface of the second sliding portion 24.

[0074] Figure 2 The clutch mechanism 20 shown is a mechanism for transmitting and blocking the rotational force of the drum 3 and the handle 5. For example... Figure 4A and Figure 4B As shown, the clutch mechanism 20 includes an engagement pin 4d and a pair of engagement recesses 15f.

[0075] like Figure 4A As shown, when the pinion 15 is in the transmission position, the engaging pin 4d engages with the engaging recess 15f, transmitting the rotational force of the handle 5 to the drum 3. On the other hand, as... Figure 4B As shown, when the pinion 15 is in the blocking position, the engaging pin 4d disengages from the engaging recess 15f, preventing the rotational force of the handle 5 from being transmitted to the drum 3.

[0076] The engagement of the locking pin 4d and the locking recess 15f is disengaged. Figure 2 The clutch operating component 21 and clutch control mechanism 22 shown are used. Figure 2 As shown, the clutch operating component 21 is located at the rear of the winding body 2.

[0077] like Figure 2 As shown, the clutch control mechanism 22 is disposed between the clutch operating member 21 and the pinion 15. Additionally, the clutch control mechanism 22 is disposed between the handle 5 and the pinion 15.

[0078] The clutch control mechanism 22 moves the pinion 15 between a transmission position and a disengagement position. In other words, the clutch control mechanism 22 engages with the recess 15g of the pinion 15 (see reference). Figure 4A and Figure 4B This causes the pinion 15 to move axially. It should be noted that the structure of the clutch control mechanism 22 is the same as that in the prior art, therefore, a description is omitted here.

[0079] The following describes the operating mode of the pinion 15. When the rotational force of the handle 5 is transmitted to the drum 3, as follows... Figure 4A As shown, pinion 15 is in the transmission position. In this transmission state, if the angler pushes the clutch operating component 21, the clutch control mechanism 22 causes pinion 15 to move from the transmission position (see reference 22). Figure 4A Orientation towards the blocking position (reference) Figure 4B It moves axially. At this time, the first bearing 16a and the second bearing 16b slide relative to the first sliding part 23 and the second sliding part 24 respectively, and move together with the pinion 15 toward the blocking position.

[0080] When the rotational force of handle 5 is not transmitted to the drum 3 in the blocking state, such as Figure 4B As shown, the pinion 15 is in the blocking position. In this blocking state, if the angler rotates the handle 5, the pinion 15 moves axially from the blocking position toward the transmission position via the clutch control mechanism 22. At this time, the first bearing 16a and the second bearing 16b slide relative to the first sliding part 23 and the second sliding part 24 respectively, and move toward the transmission position together with the pinion 15 (see reference). Figure 4A )move.

[0081] In the dual-bearing reel 100 with the above-described structure, when the pinion 15 moves between the transmission position and the blocking position, the first bearing 16a and the second bearing 16b move together with the pinion 15. Therefore, it is not necessary to provide gaps between the first inner ring 16a1 of the first bearing 16a and the outer peripheral surface of the pinion 15, or between the second inner ring 16b1 of the second bearing 16b and the outer peripheral surface of the pinion 15.

[0082] Therefore, it is possible to prevent electrolyzed water such as salt water from seeping into the space between the first inner ring 16a1 of the first bearing 16a and the outer peripheral surface of the pinion 15, and between the second inner ring 16b1 of the second bearing 16b and the outer peripheral surface of the pinion 15. That is, in the dual-bearing winding reel 100, it is possible to prevent the outer peripheral surface of the pinion 15 from becoming firmly attached to the first inner ring 16a1 of the first bearing 16a, and to prevent the outer peripheral surface of the pinion 15 from becoming firmly attached to the second inner ring 16b1 of the second bearing 16b. This allows the pinion 15 to move smoothly.

[0083] In the dual-bearing cable reel 100, a first sliding portion 23 is disposed between the cable reel body 2 and the first outer ring 16a2 of the first bearing 16a. A second sliding portion 24 is disposed between the cable reel body 2 and the second outer ring 16b2 of the second bearing 16b. This structure allows the first bearing 16a and the second bearing 16b to move smoothly together with the pinion 15.

[0084] In the dual-bearing reel 100, the first bearing 16a is disposed at the first end 15d on the gear portion 15b side of the pinion 15. Therefore, the first bearing 16a moves axially together with the pinion 15 while adjacent to the gear portion 15b of the pinion 15. As a result, the pinion 15 can rotate stably when it is in the transmission position.

[0085] In the dual-bearing reel 100, the second bearing 16b is provided at the second end 15e on the transmission part 15c side of the pinion 15, so that the pinion 15 can be rotated stably by the first bearing 16a and the second bearing 16b.

[0086] <Variation Example>

[0087] The present invention has been described above as one embodiment, but the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the invention. Furthermore, the following variations can be combined arbitrarily as needed.

[0088] (A) such as Figure 5 As shown, the dual-bearing cable reel 100 may also include a force-applying section 25. Figure 5 This diagram shows the pinion 15 in the transmission position. In this modified example, when the first bearing 16a moves together with the pinion 15, the force-applying part 25 applies force to the first bearing 16a. In this modified example, the anti-disengagement component 18 of the above embodiment is omitted. Because the force-applying part 25 applies force to the first bearing 16a, even if the anti-disengagement component 18 is omitted, the first bearing 16a can still move together with the pinion 15.

[0089] The force-applying part 25 is in the axial direction from the blocking position toward the transmission position. Figure 5 In the left direction, a force is applied to the first outer ring 16a2 of the first bearing 16a. More specifically, when the pinion 15 moves from the blocking position to the transmitting position, the force-applying part 25 applies a force to the first bearing 16a so that the first bearing 16a follows the movement of the pinion 15. In this embodiment, the force-applying part 25 is a helical spring.

[0090] With the pinion 15 in the transmission position, the helical spring 25 is compressed and positioned axially between the outer ring 11a1 of the bearing 11a and the first outer ring 16a2 of the first bearing 16a. Therefore, when the pinion 15 moves from the blocking position to the transmission position, the outer ring 16a2 of the first bearing 16a is forced by the helical spring 25 in the direction of movement of the pinion 15. This allows the first bearing 16a and the pinion 15 to move more smoothly together in the dual-bearing cable reel 100.

[0091] (B) such as Figure 6 As shown, the dual-bearing cable reel 100 may have a waterproof section 28. Figure 6 This diagram shows the pinion 15 in the transmission position. A waterproof section 28 prevents water from seeping into the first bearing 16a. The waterproof section 28 is provided on the outer peripheral surface of the pinion 15. Specifically, the waterproof section 28 is provided on the outer peripheral surface of the first end 15d of the pinion 15. The waterproof section 28 is axially positioned between the first bearing 16a and the gear portion 15b.

[0092] In detail, the waterproof portion 28 is formed in a ring shape. The inner periphery of the waterproof portion 28 is axially positioned between the first inner ring 16a1 of the first bearing 16a and the gear portion 15b. The outer periphery of the waterproof portion 28 is axially positioned between the first outer ring 16a2 of the first bearing 16a and the gear portion 15b. The outer periphery of the waterproof portion 28 is radially positioned further inward than the first sliding portion 23. Therefore, in the dual-bearing cable reel 100, water can be prevented from seeping into the interior of the first bearing 16a, thereby allowing the first bearing 16a to rotate smoothly.
