Summary of the Invention

Problems to be Solved by the Invention

[0004] In the conventional oscillating mechanism, since the cam gear meshes with the sliding gear, strength and rigidity are required. Therefore, generally, the cam gear is formed of metal. For example, the cam gear is formed of one metal member. Therefore, when the spinning reel has an oscillating mechanism, the weight of the spinning reel may increase. Furthermore, in the prior art described in Patent Document 1, the gear body of the cam gear is made up of a gear portion and a main body portion provided on the inner circumference side of the gear portion to support the gear portion, thereby reducing weight. Here, the boss portion is configured to protrude from the main body portion. Since the boss portion moves along the engagement groove, the main body portion requires strength. For this reason, there was a limit to how much the weight of the main body portion could be reduced. In other words, if a spinning reel has an oscillating mechanism, the weight of the spinning reel may increase.

[0005] The objective of the present invention is to provide an oscillating mechanism that can reduce the weight of a spinning reel. [Means for solving the problem]

[0006] The oscillating mechanism of a spinning reel according to the first aspect of the present invention moves the spool shaft in the spool axial direction in conjunction with the rotation of the handle shaft. The oscillating mechanism comprises a sliding gear, a cam gear, and a slider. The sliding gear rotates in conjunction with the rotation of the handle shaft.

[0007] The cam gear has a metal gear section and a resin support section. The metal gear section includes a gear body that meshes with the sliding gear and a boss section that protrudes from the gear body. The resin support section supports the radially inner portion of the gear section and rotates integrally with the gear section.

[0008] The slider is mounted on the spool shaft. The slider includes an engagement groove into which a boss portion engages. As the boss portion moves along the engagement groove, the slider moves the spool shaft in the spool axis direction.

[0009] In this oscillating mechanism, the gear portion of the cam gear, such as the gear body and boss portion, is made of metal, thus ensuring the strength and rigidity required for meshing with the sliding gear. Furthermore, since the support portion of the cam gear is made of resin, the oscillating mechanism can be made lighter. In other words, by using this oscillating mechanism, the spinning reel can be made lighter.

[0010] In an oscillating mechanism for a spinning reel according to a second aspect of the first aspect of the present invention, preferably, the gear portion includes a first engaging portion that protrudes radially inward from the gear body. The support portion includes a first recess that opens radially outward and into which the first engaging portion engages.

[0011] In this oscillating mechanism, the gear section and the support section can be rotated integrally with a simple configuration by engaging the first engaging section of the gear section with the first recess of the support section.

[0012] In the oscillating mechanism of a spinning reel according to a third aspect of the second aspect of the present invention, preferably, the boss portion protrudes from the first engagement portion in the direction of the cam gear axis.

[0013] In this oscillating mechanism, the boss portion is made to protrude from the first engagement portion in the axial direction of the cam gear, thereby ensuring that the boss portion is securely engaged with the engagement groove.

[0014] In an oscillating mechanism for a spinning reel according to a fourth aspect of the second or third aspect of the present invention, the support portion preferably includes a main body portion that is positioned radially inward of the gear portion and supports the gear portion, and a flange portion that extends radially outward from the main body portion and is positioned on the axially outer surface of the gear portion. The first recess is provided in the main body portion and the flange portion.

[0015] In this oscillating mechanism, the flange portion of the support portion is positioned on the axially outer surface of the gear portion, allowing the main body portion of the support portion to be easily positioned radially inward of the gear portion in the direction of the cam gear axis. Furthermore, since the first recess is provided in the main body portion and the flange portion, the gear portion and the support portion can be reliably rotated as a single unit.

[0016] In an oscillating mechanism for a spinning reel according to a fifth aspect of any one of the second to fourth aspects of the present invention, preferably, the gear portion includes a second engaging portion that protrudes radially inward from the gear body at a position different from that of the first engaging portion. The support portion includes a second recess that opens radially outward and into which the second engaging portion engages.

[0017] In this oscillating mechanism, the gear section and the support section can be rotated integrally with a simple configuration by engaging the second engaging section of the gear section with the second recess of the support section.

[0018] In the oscillating mechanism for a spinning reel according to the sixth aspect of the fifth aspect of the present invention, preferably, the support portion has a main body portion that is arranged radially inward of the gear portion and supports the gear portion, and a flange portion that extends radially outward from the main body portion and is arranged on the axial outer surface of the gear portion. The second recess is provided in the main body portion.

[0019] In this oscillating mechanism, the flange portion of the support portion is positioned on the axially outer surface of the gear portion, allowing the main body of the support portion to be easily positioned radially inward of the gear portion in the direction of the cam gear axis. Furthermore, since a second recess is provided in the main body, the gear portion and the support portion can be reliably rotated as a single unit.

[0020] In an oscillating mechanism for a spinning reel according to a seventh aspect according to any one of the first to sixth aspects of the present invention, the gear portion preferably contains zinc.

[0021] In this oscillating mechanism, the gear section contains zinc, which ensures the strength and rigidity of the cam gear.

[0022] In the oscillating mechanism of the spinning reel according to the eighth aspect according to any one of the first to seventh aspects of the present invention, preferably, the support portion includes at least one of polyoxymethylene resin and polyacetal resin.

[0023] In this oscillating mechanism, since the support portion includes at least one of polyoxymethylene resin and polyacetal resin, the cam gear can be suitably lightened.

[0024] The spinning reel according to the ninth aspect of the present invention includes a reel body, a spool shaft that is movably attached to the reel body in the front-rear direction, a handle shaft that is rotatably supported with respect to the reel body, and the oscillating mechanism described above.

[0025] In this spinning reel, weight reduction can be achieved by using the oscillating mechanism described above.

Advantages of the Invention

[0026] In the present invention, weight reduction of the oscillating mechanism in the spinning reel can be achieved. In the present invention, weight reduction of the spinning reel can be achieved.

[0028] A spinning reel 1 employing one embodiment of the present invention comprises, as shown in Figure 1, a reel body 3, a handle 5, a rotor 7, a spool 11, a drive unit 13 (see Figure 2), and an oscillating mechanism 30 (see Figure 2).

[0029] As shown in Figure 1, the handle 5 is rotatably supported on the reel body 3. In this embodiment, an example is shown where the handle 5 is located on the left side of the reel body 3. The handle 5 may also be located on the right side of the reel body 3. As shown in Figure 2, an oscillating mechanism 30 for moving the spool 11 in the forward and backward directions is located in the internal space of the reel body 3.

[0030] The rotor 7 shown in Figures 1 and 2 is used to wind fishing line onto the spool 11. The rotor 7 is located at the front of the reel body 3. The rotor 7 is configured to be rotatable relative to the reel body 3. For example, the rotor 7 is connected to the pinion gear 17 so as to rotate integrally with the pinion gear 17. The pinion gear 17 is rotatably supported by the reel body 3.

[0031] A fishing line is wound around the spool 11 shown in Figures 1 and 2. The spool 11 is configured to move integrally with the spool shaft 9. For example, as shown in Figure 2, the spool 11 is attached to the tip of the spool shaft 9.

[0032] The spool shaft 9 shown in Figure 2 is configured to move back and forth within the reel body 3. The spool shaft 9 is supported so as to be movable in the spool axis direction relative to the reel body 3. The spool axis direction is the direction in which the spool axis X1 of the spool shaft 9 extends. The spool axis direction may also be interpreted as the front-to-back direction.

[0033] The spool shaft 9 is inserted through the inner circumference of the cylindrical pinion gear 17. The spool shaft 9 reciprocates in the spool axis direction relative to the reel body 3 by the operation of the oscillating mechanism 30.

[0034] As shown in Figure 2, the drive unit 13 includes a drive shaft 21, a drive gear 23, and a sliding gear 31. The drive shaft 21 rotates in conjunction with the rotation of the handle 5. For example, the handle shaft 6 of the handle 5 is mounted on the drive shaft 21.

[0035] The drive shaft 21 has a drive axis X2. For example, the drive shaft 21 is formed in a cylindrical shape. A handle shaft 6 is detachably mounted on the inner circumference of the drive shaft 21. The handle shaft 6 is rotatably supported by the reel body 3. The axis of the handle shaft 6 is concentric with the drive axis X2. A drive gear 23 is used to rotate the rotor 7. The drive gear 23 is provided on the drive shaft 21. The drive gear 23 meshes with the pinion gear 17.

[0036] The sliding gear 31 is used to move the spool shaft 9. The sliding gear 31 rotates in the first rotational direction R1 in conjunction with the rotation of the handle shaft 6. The sliding gear 31 is mounted on the drive shaft 21 at a distance from the drive gear 23 in the axial direction from which the drive shaft center X2 extends. The spool shaft 9 and the guide shaft 34 (described later) are positioned between the drive gear 23 and the sliding gear 31. The sliding gear 31 meshes with the cam gear 33, which will be described later.

[0037] The drive shaft 21, drive gear 23, and sliding gear 31 are formed as a single unit. The drive shaft 21, drive gear 23, and sliding gear 31 may be formed separately from each other. The drive shaft 21, drive gear 23, and sliding gear 31 rotate in conjunction with the rotation of the handle shaft 6. When the drive gear 23 and sliding gear 31 rotate, the pinion gear 17 and cam gear 33 rotate.

[0038] For example, in this embodiment, the rotational direction in which the handle shaft 6, drive shaft 21, drive gear 23, and sliding gear 31 rotate to wind up the fishing line is defined as the first rotational direction R1. The rotational direction opposite to the first rotational direction R1 is defined as the second rotational direction R2. The first rotational direction R1 and the second rotational direction R2 are defined for the drive shaft X2 and shaft X3, respectively.

[0039] When the handle shaft 6, drive shaft 21, drive gear 23, and sliding gear 31 rotate in the first rotational direction R1 with respect to the drive shaft center X2, the cam gear 33 rotates in the second rotational direction R2 with respect to the shaft center X3.

[0040] The oscillating mechanism 30 shown in Figure 2 moves the spool shaft 9 in the spool axis direction in conjunction with the rotation of the handle shaft 6. As shown in Figure 3, the oscillating mechanism 30 includes a sliding gear 31, a cam gear 33, a guide shaft 34, and a slider 35.

[0041] The sliding gear 31 constitutes the drive unit 13 as described above. In Figure 3, the teeth 31a of the sliding gear 31 are shown in a simplified manner. The teeth 31a include multiple gear teeth. The cam gear 33 is used to move the slider 35 in the spool axis direction. The cam gear 33 is rotatably supported on the reel body 3. For example, the cam gear 33 is positioned between the reel body 3 and the slider 35. The cam gear 33 is rotatably supported on the first boss portion 3b of the reel body 3.

[0042] Here, as shown in Figures 2 and 3, the first boss portion 3b is included in the reel body 3. That is, the reel body 3 has a main body portion 3a, a first boss portion 3b, and a side cover 3e (see Figure 1). The main body portion 3a and the side cover 3e form a space for arranging the oscillating mechanism 30.

[0043] As shown in Figure 4, the cam gear 33 has a metal gear portion 45 and a resin support portion 47. The gear portion 45 is made of metal. The metal contains zinc. Preferably, the metal is a zinc-containing alloy.

[0044] As shown in Figure 5, the gear portion 45 includes a gear body 45a and a second boss portion 45b (an example of a boss portion). The gear portion 45 further includes a first projection 45c, a second projection 45d (an example of a first engaging portion), and a third projection 45e (an example of a second engaging portion).

[0045] The gear body 45a meshes with the sliding gear 31. For example, the gear body 45a is formed in a substantially annular shape. Teeth 45f are provided on the outer circumference of the gear body 45a. Teeth 45f include multiple gear teeth. The teeth 45f of the gear body 45a mesh with the teeth 31a of the sliding gear 31 (see Figure 3).

[0046] As shown in Figure 5, the first projection 45c protrudes from the gear body 45a in the axial direction of the cam gear. For example, the first projection 45c protrudes from the outer surface of the gear body 45a in the axial direction of the cam gear. The first projection 45c is formed integrally with the gear body 45a. The second projection 45d protrudes radially inward from the gear body 45a. For example, the second projection 45d protrudes inward from the inner circumferential surface of the gear body 45a in the radial direction of the cam gear. The second projection 45d is formed integrally with the first projection 45c and the gear body 45a.

[0047] The third projection 45e protrudes radially inward from the gear body 45a at a different position from the second projection 45d. For example, the third projection 45e protrudes inward from the inner circumferential surface of the gear body 45a in the radial direction of the cam gear. The third projection 45e is formed integrally with the gear body 45a.

[0048] As shown in Figure 5, the second boss portion 45b protrudes from the gear body 45a. For example, the second boss portion 45b protrudes from the first projection portion 45c in the cam gear axial direction. More specifically, the second boss portion 45b protrudes from the outer surface of the first projection portion 45c in the cam gear axial direction. The second boss portion 45b is formed integrally with the first projection portion 45c. The second boss portion 45b engages with the engagement groove 37 of the slider 35, which will be described later.

[0049] As shown in Figure 3, the second boss portion 45b is positioned inside the engagement groove 37 and moves along the engagement groove 37 in conjunction with the rotation of the gear body 45a. The second boss portion 45b is formed in a cylindrical shape. In this embodiment, an example is shown in which the second boss portion 45b is formed in a cylindrical shape, but the second boss portion 45b may also be formed in a frustoconical shape.

[0050] The support portion 47 shown in Figures 4 and 7 is formed of resin. The resin contains at least one of polyoxymethylene resin and polyacetal resin. Preferably, the resin is a synthetic resin containing at least one of polyoxymethylene resin and polyacetal resin.

[0051] The support portion 47 is supported on the reel body 3 so as to be rotatable around the axis X3. As shown in Figure 7, the support portion 47 supports the radially inner portion of the gear body 45a. For example, the support portion 47 supports the inner surface of the gear body 45a in the radial direction of the cam gear. The support portion 47 rotates integrally with the gear body 45a.

[0052] As shown in Figure 8, the support portion 47 has a main body portion 47a and a flange portion 47b. The support portion 47 further has a first recess 47c and a second recess 47d. The support portion 47 further has a hole portion 47e.

[0053] As shown in Figures 7 and 8, the main body 47a supports the gear body 45a. The main body 47a is positioned radially inward of the gear body 45a. For example, the main body 47a is positioned inside the gear body 45a in the cam gear radial direction. The main body 47a is formed substantially annularly. The main body 47a is press-fitted into the inner circumferential surface of the gear body 45a.

[0054] As shown in Figure 8, the flange portion 47b extends radially outward from the main body portion 47a. The flange portion 47b is positioned opposite the axially outer surface of the gear body 45a. For example, the flange portion 47b contacts the outer surface of the gear body 45a in the cam gear axial direction. The outer surface of the gear body 45a is the surface on which the second boss portion 45b is formed. The flange portion 47b is formed in a substantially annular shape.

[0055] The first recess 47c is provided in the main body portion 47a and the flange portion 47b. The first recess 47c opens radially outward. The second projection 45d (see Figure 5) engages with the first recess 47c. For example, the first projection 45c (see Figures 4 and 5) and the second projection 45d (see Figure 5) engage with the first recess 47c. The second recess 47d is provided in the main body portion 47a. The second recess 47d opens radially outward. As shown in Figure 7, the third projection 45e engages with the second recess 47d.

[0056] As shown in Figure 8, the first boss portion 3b of the reel body 3 (see Figures 2 and 3) is positioned in the hole 47e. The axis X3 passes through the center of the hole 47e.

[0057] As shown in Figures 2 and 3, the guide shaft 34 is used to guide the slider 35 in the spool axis direction. The guide shaft 34 is positioned above the spool shaft 9. The guide shaft 34 is positioned parallel to the spool shaft 9 (spool axis X1) and is fixed to the reel body 3 (body part 3a).

[0058] As shown in Figure 3, the slider 35 is used to move the spool shaft 9 in the spool axis direction. The slider 35 is mounted on the spool shaft 9. For example, the slider 35 has a slider body 36 and an engagement groove 37. The slider body 36 is fixed to the rear end of the spool shaft 9. A guide shaft 34 is inserted through the slider body 36. The slider body 36 moves in the spool axis direction along the guide shaft 34.

[0059] A second boss portion 45b is positioned in the engagement groove 37. The engagement groove 37 is provided in the slider body 36. For example, when the slider body 36 is mounted on the spool shaft 9 and the guide shaft 34, the engagement groove 37 extends upward from the spool shaft 9.

[0060] As shown in Figure 3, when the engagement groove 37 is viewed from the handle 5 side in the axial direction in which the drive shaft X2 extends, the engagement groove 37 is formed in a curved shape. For example, in this case, the engagement groove 37 is formed in an S-shape. The second boss portion 45b engages with the engagement groove 37. As the second boss portion 45b moves along the engagement groove 37, the slider body 36 moves the spool shaft 9 in the spool axial direction along the guide shaft 34.

[0061] The oscillating mechanism 30 of the spinning reel 1 described above has the following features. In the oscillating mechanism 30, the gear portion 45 of the cam gear 33, for example, the gear body 45a and the second boss portion 45b, are made of metal, so the strength and rigidity required for meshing with the sliding gear 31 can be ensured. In addition, since the support portion 47 of the cam gear 33 is made of resin, the weight of the oscillating mechanism 30 can be reduced. In other words, by using the oscillating mechanism 30, the weight of the spinning reel 1 can be reduced.

[0062] In the oscillating mechanism 30, the gear portion 45 and the support portion 47 can be rotated integrally with a simple configuration by engaging the first protrusion 45c of the gear portion 45 with the first recess 47c of the support portion 47.

[0063] In the oscillating mechanism 30, the second boss portion 45b is made to protrude from the first projection portion 45c in the cam gear axial direction, thereby ensuring that the second boss portion 45b engages with the engagement groove 37.

[0064] In the oscillating mechanism 30, the flange portion 47b of the support portion 47 is positioned on the axially outer surface of the gear portion 45, so that the main body portion 47a of the support portion 47 can be easily positioned radially inward of the gear portion 45 in the direction of the cam gear axis. Furthermore, since the first recess 47c is provided on the main body portion 47a and the flange portion 47b, the gear portion 45 and the support portion 47 can be reliably rotated as a single unit.

[0065] In the oscillating mechanism 30, the gear portion 45 and the support portion 47 can be rotated integrally with a simple configuration by engaging the third protrusion 45e of the gear portion 45 with the second recess 47d of the support portion 47.

[0066] In the oscillating mechanism 30, the flange portion 47b of the support portion 47 is positioned on the axially outer surface of the gear portion 45, so that the main body portion 47a of the support portion 47 can be easily positioned radially inward of the gear portion 45 in the direction of the cam gear axis. Furthermore, since the second recess 47d is provided in the main body portion 47a, the gear portion 45 and the support portion 47 can be reliably rotated as a single unit.

[0067] In the oscillating mechanism 30, the gear portion 45 contains zinc, which ensures the strength and rigidity of the cam gear 33. In the oscillating mechanism 30, the support portion 47 contains at least one of polyoxymethylene resin and polyacetal resin, which allows for a suitable reduction in the weight of the cam gear 33.

[0068] By configuring the oscillating mechanism 30 as described above, the spinning reel 1 can be made suitably lighter. [Industrial applicability]

[0069] The present invention can be used in the oscillating mechanism of a spinning reel, and in the spinning reel itself. [Explanation of Symbols]
