Summary of the Invention

Problems to be Solved by the Invention

[0005] As described above, the line roller can be subjected to a large load from the fishing line while guiding it. When a large load is applied to the line roller, a gap may form between the arm lever and the support shaft. This gap can cause looseness in the line roller and potentially loosen the screw.

[0006] The present invention aims to provide a spinning reel for fishing equipped with a fishing line guide device that stably supports the line roller. [Means for solving the problem]

[0007] The spinning reel for fishing according to the present invention comprises a spool around which fishing line is wound, a rotor equipped with a pair of support arms that rotate around the spool, arm levers rotatably supported on the tip sides of the pair of support arms, and a fishing line guide device provided between one arm lever and a line slider on which one end of a bail for picking up fishing line is provided, for guiding the fishing line onto the spool. The fishing line guide device comprises a support shaft fixed between the arm lever and the line slider, and a line roller rotatably supported via a ball bearing positioned and fixed to the support shaft. The support shaft has a flange formed on the arm lever side that is larger in diameter than the inner ring of the ball bearing, and the arm lever is fixed in contact with the flange.

[0008] In the fishing line guide device of the spinning reel with the above configuration, even if a large load is applied to the line roller from the fishing line, the force acting on the ball bearing supporting the line roller, especially the force acting in the axial direction, is absorbed by the flange portion. As a result, the arm lever and This reduces the likelihood of gaps forming between the support shaft and the line roller, preventing the line roller from becoming loose and causing the screw member that secures the support shaft to loosen. [Effects of the Invention]

[0009] According to the present invention, a spinning reel for fishing can be obtained that is equipped with a fishing line guide device in which the line roller is stably supported. [Brief explanation of the drawing]

[Figure 3] Cross-sectional view along line AA in Figure 2. [Figure 4] A diagram showing the internal configuration of the second embodiment of the fishing line guide device. [Figure 5] A diagram showing the internal configuration of the third embodiment of the fishing line guide device. [Modes for carrying out the invention]

[0011] Hereinafter, one embodiment of the spinning reel for fishing according to the present invention will be specifically described with reference to Figures 1 to 3.

[0012] The reel body 2 of the spinning reel 1 for fishing has a leg portion 2A formed thereon that is attached to a fishing rod. Inside the reel body 2, a handle shaft for winding the handle 3 is rotatably supported via a bearing. A known drive force transmission mechanism is also connected to the handle shaft, and as the handle 3 is rotated, it rotates the rotor 10 and, via a known oscillating mechanism, reciprocates the spool 5 on which the fishing line is wound.

[0013] The spool 5 is made of a lightweight metal such as aluminum, aluminum alloy, or magnesium alloy, or a synthetic resin material, and has a fishing line winding section 5a around which the fishing line is wound, and a front flange section 5b and a rear flange section (skirt section) 5c that define the amount of line wound on the fishing line winding section 5a in the front-rear direction.

[0014] The rotor 10 is provided with a pair of support arms 11 (only one shown) that extend axially forward and face each other at approximately 180° intervals. The spool 5 is located between the pair of support arms and is driven to reciprocate back and forth via a known oscillating mechanism. Arm levers (only one shown) 15 are supported at the tips of both support arms so as to be rotatable between a fishing line winding position and a fishing line release position. The base end of a semi-annular bail 17 for picking up the fishing line is attached to each bail support member, and the bail 17 is rotatable together with the arm levers 15.

[0015] The tip of one of the arm levers 15 is provided with a fishing line guide device 20 for guiding the fishing line onto the spool 5. This fishing line guide device 20 includes a line slider 22 to which one end of the bail 17 is attached, and a rotatable line roller 28 positioned between the arm lever 15 and the line slider 22 for guiding the fishing line.

[0016] In the configuration described above, when the handle 3 is turned in the winding rotation operation, the rotor 10 is rotated via the drive force transmission mechanism, and the spool 5 is moved back and forth via the oscillating mechanism. As a result, the fishing line is wound evenly onto the spool 5 without shifting, while sliding against the line roller 28 of the fishing line guide device 20.

[0017] Next, the fishing line guide device 20 of this embodiment will be described. As shown in Figure 2, the fishing line guide device 20 of this embodiment includes a support shaft 23 fixed between the arm lever 15 and the line slider 22, and a ball bearing positioned and fixed to the support shaft 23. The system includes rings (bearings) 25A and 25B, and the line roller 28 which is rotatably supported on the support shaft 23 via these ball bearings 25A and 25B. Although the ball bearings shown in the figure are arranged in multiples (2) at regular intervals along the axial direction, there may be only one.

[0018] The line slider 22 is formed to guide the fishing line from the proximal end of the veil 17 to the line roller 28. The line slider 22 of the present embodiment is formed separately from the support shaft 23 and is configured to be able to insert the support shaft 23 from the arm lever 15 side. That is, if the support shaft 23 is integrally formed with the line slider 22, when trying to form a flange on the support shaft as described later, the ball bearing cannot be installed. However, by forming the line slider 22 and the support shaft 23 separately, the ball bearing can be installed even if a flange is formed on the support shaft 23. The support shaft 23 is configured as a socket screw that extends in the axial direction with an opening on the line slider side, and an internal thread portion 23a is formed on the inner surface of the opening.

[0019] An annular protrusion 28a protruding radially inward is formed in the middle portion of the line roller 28, and the side surfaces of the outer rings 27 of the ball bearings 25A and 25B are respectively applied and positioned on both sides of the annular protrusion 28a.

[0020] Magnetic seal mechanisms 30A and 30B are disposed on the support shaft 23 adjacent to the ball bearings 25A and 25B. The magnetic seal mechanisms 30A and 30B of the present embodiment include a ring-shaped magnet 32 fixed thereto and a pole plate 31 made of a magnetic material supported on the support shaft 23 so as to face the outer surface of each ball bearing. A magnetic circuit is formed between the outer surface of each bearing and the pole plate 31, and the ball bearings 25A and 25B are sealed by holding a magnetic fluid 33 in the gap between the magnet and the outer surface of the bearing. Further, the magnetic seal mechanisms 30A and 30B are applied to the inner rings 26 of the ball bearings 25A and 25B with an O-ring (washer) interposed therebetween, and also have a function of restricting the ball bearings.

[0021] The support shaft 23 has a flange 23b formed on the side facing the arm lever 15, which is larger in diameter than the inner rings 26 of the ball bearings 25A and 25B. That is, a flange 23b is formed that is larger in diameter than the inner ring 26 (projecting radially from the surface of the support shaft 23). The arm lever 15 is fixed against the side surface (restricting wall) 23b' of the flange 23b, and the arm lever 15 is also fixed overlapping the radial circumferential surface 23b'' of the flange 23b. Furthermore, on the outer circumferential surface of the support shaft 23 in this embodiment, a stepped portion 23c is formed continuously with the flange 23b, decreasing in diameter in a stepped manner axially outward. The arm lever 15 is fixed against the side surface (restricting wall) 23c' of the stepped portion 23c, similar to the side surface (restricting wall) 23b' of the flange 23b, and the arm lever 15 is also fixed overlapping the radial circumferential surface 23c'' of the stepped portion 23c.

[0022] The arm lever 15 and the line slider 22 have openings 15A and 22A, respectively. The support shaft 23 is inserted from the side of opening 15A, and a screw member 35 for fixing the support shaft 23 and the line slider 22 is inserted from the line slider side through the opening 22A.

[0023] The support shaft 23 is fixed by screwing in a threaded member 35 that is inserted through the opening 22A of the line slider 22. That is, the support shaft 23 is fixed by screwing the male threaded portion 35a of the threaded member 35 into the female threaded portion 23a formed on the inner surface of the support shaft 23 and tightening it. The threaded member 35 may also be inserted and screwed in from the arm lever side.

[0024] In this case, the end of the support shaft 23 on the arm lever 15 side has a length that protrudes from the opening 15A. The arm lever 15 and the support shaft 23 are integrated by crimping the portion 23d that protrudes from the arm lever 15. In other words, by fixing the protruding side of the support shaft 23 with crimping, the engagement length of the two parts can be minimized, thereby making the arm lever 15 thinner and more compact, and suppressing an increase in inertia. In addition, the compact size of the arm lever 15 makes it less likely for the fishing line to get tangled, thus preventing line troubles.

[0025] Furthermore, by riveting, the support shaft 23 and the arm lever 15 are integrated, which allows for a larger seating surface in accordance with the configuration of the stepped portion 23c, thereby stabilizing the fixing portion of both. As a result, even if high tension is applied to the support shaft 23, the receiving surface of the arm lever 15 is less likely to buckle, preventing the intrusion of foreign matter and thus preventing corrosion.

[0026] Furthermore, by crimping the support shaft 23 on the arm lever 15 side, the screw member 35 and the support shaft 23 can be inserted from the line slider 22 side, allowing the screw member 35 and the line slider 22 to be brought closer to the center compared to conventional reels. In addition, since the weighted head 35b of the screw member 35 faces inward when the rotor rotates, it is possible to reduce inertia. Moreover, the support shaft 23 in this embodiment is formed with a bottom on the arm lever 15 side, and the screw member is not screwed in from the arm lever side, so the head of the screw member is not exposed, improving the appearance.

[0027] While the aforementioned crimping can be performed by press working or high-spin machining, in this embodiment, the arm lever 15 and the support shaft 23 are fixed by high-spin crimping to ensure accurate crimping without misalignment. Furthermore, when performing such crimping, it is preferable to use metal (aluminum for the arm lever, SUS for the support shaft and screw members, etc.) to prevent cracking or damage during the processing.

[0028] Preferably, the screw member 35 is configured to be screwed onto the support shaft 23 along the entire axial length of the line roller 28. With this configuration, when tension from the fishing line acts on the line roller 28, it can be supported by the screw member 35, which is longer than the axial length of the line roller 28, thus making it less likely for looseness or other issues to occur.

[0029] Furthermore, in the configuration of this embodiment, the inner rings 26 of the ball bearings 25A and 25B are in contact with the outer circumferential surface of the support shaft 23, and the contact surfaces between the arm lever 15 and the support shaft 23 (side surface 23b' and circumferential surface 23b'' of the flange 23b, and side surface 23c' and circumferential surface 23c'' of the stepped portion 23c) are located axially outward from the line roller 28. This makes it possible to distribute the force acting from the fishing line, and effectively suppresses looseness and other issues. In particular, as described above, these contact portions are stepped and in close contact with the support shaft 23, so the contact surface is increased, and the axial force acting on the ball bearings 25A and 25B supporting the line roller 28 can be effectively absorbed by the flange portion. As a result, gaps are less likely to occur between the arm lever 15 and the support shaft 23, and the line roller portion is prevented from loosening, which would cause the screw member 35 that fixes the support shaft 23 to loosen.

[0030] Furthermore, since the contact surface (contact surface) between the arm lever 15 and the support shaft 23 is located axially outward from the line roller 28, there is no joint inside the inner ring 26 of the ball bearings 25A and 25B. Therefore, even if a large load is applied to the line roller 28 and a large impact is applied through the ball bearings 25A and 25B, no looseness will occur.

[0031] As shown in Figure 3, it is preferable to form a non-circular cross-section portion on the support shaft 23 and to prevent the arm lever 15 from rotating by fitting it with the non-circular cross-section portion. By forming a split section 23f and creating an oval cross-sectional shape, the support shaft 23 can be prevented from rotating, thereby preventing the arm lever 15 from wobbling relative to the support shaft.

[0032] Figure 4 shows the internal configuration of the second embodiment of the fishing line guide device. In the embodiments described below, components identical to those in the first embodiment shown in Figure 2 are denoted by the same reference numerals, and detailed descriptions are omitted.

[0033] In this embodiment, a protrusion 15B, which is formed to protrude toward the line slider side, is attached to the side surface (regulating wall) 23b' of the flange 23b formed on the support shaft 23, in the central region of the arm lever 15. This protrusion 15B has a stepped portion that gradually decreases in diameter toward the axial outward side, and the inner surface of the protrusion 15B is fixed to the side surface (regulating wall) 23c' of the stepped portion 23c which is continuously formed with the flange 23b, and to the radial circumferential surface 23c'' of the stepped portion 23c.

[0034] In this way, by forming a protrusion 15B in the central region of the arm lever 15 and applying the support shaft 23 to this portion, the contact area can be increased, allowing it to stably receive forces acting in the axial direction and effectively suppressing looseness.

[0035] Figure 5 shows the internal configuration of the third embodiment of the fishing line guide device. In this embodiment, the portion of the support shaft 23 into which the screw member 35 of the second embodiment is screwed is open and penetrates on the arm lever side (an opening is formed). Furthermore, the portion 23d that protrudes from the arm lever 15 is fixed to the arm lever 15 by crimping using high-spin machining.

[0036] This configuration makes it easier to thread the screw member 35, thereby reducing manufacturing costs.

[0037] Although embodiments of the present invention have been described above, the present invention is not limited to the embodiments described above and can be implemented in various modified forms.

[0038] For example, the flange 23b formed on the support shaft 23 can be appropriately modified in terms of the flange, the shape of the continuously formed stepped portion, and the joining method of the arm lever, as long as a large contact area can be formed between it and the arm lever 15. Furthermore, the magnetic seal mechanisms 30A and 30B in the above-described embodiment can be appropriately modified in terms of the arrangement position, shape, size, etc., of the magnets and electrode plates. Moreover, the components shown in the above-described drawings can be appropriately combined and implemented. [Explanation of Symbols]
