Description

  The present invention relates to a fishing reel having a reel body provided with a one-way clutch.

In general, some fishing reels control the rotation state of a rotary drive shaft that is interlocked with a handle operation by a rolling one-way clutch disposed on a support portion of the reel body. In order to prevent the outer ring of such a rolling one-way clutch from rotating around the support portion of the reel body, a notch recess is provided in the edge of the outer ring on the opening end side, and the recess is fixed to the reel body with a screw. The outer ring of the one-way clutch is prevented from rotating on the reel body by engaging the rotation preventing member (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 11-18638

  However, such an anti-rotation member is positioned and fixed to the support portion via the screw by screwing the screw into the opening end of the recess that accommodates the rolling one-way clutch. For this reason, the mounting position of the anti-rotation member is easily influenced by the tightening force and dimensional accuracy of the screw, and it is difficult to maintain the concentricity with respect to the rotary drive shaft connected to the one-way clutch with high accuracy. As described above, when the concentricity of the one-way clutch with respect to the rotational drive shaft cannot be maintained with high accuracy, the reverse-rotation preventing function of the one-way clutch due to the wedge action of the rolling member between the inner ring member and the outer ring member is adversely affected. For example, inconveniences such as failure to prevent reverse rotation, uneven rotation, generation of abnormal noise, and the like, and further decrease in clutch performance and durability occur.

  In addition, since the rotation prevention member is positioned and prevented from coming off with respect to the reel body by using a common screw, the attachment state is not stable, and the workability becomes inconvenient.

  Furthermore, since the one-way clutch is prevented from coming off from the reel body by the rotation-preventing member that prevents the outer ring member of the one-way clutch from being used, it is sufficient to more reliably perform the retaining function. It is difficult to obtain strength.

  The present invention has been made based on such circumstances, and an object of the present invention is to provide a fishing reel with good workability capable of stably positioning a rotation preventing member with high accuracy. .

  The fishing reel of the present invention that achieves the above object is provided with a rolling one-way clutch that allows one-way rotational movement by a handle and prevents rotation in the other direction on a support portion of the reel body, and this one-way clutch. A fishing reel that fixes a rotation preventing member that engages with a peripheral edge of the outer ring member of the outer ring member to the support portion, and fixes the outer ring member of the one-way clutch to the support portion via the rotation prevention member. A projecting portion protruding in the axial direction from the support portion is formed on the outer peripheral side of the one-way clutch, and a mounting hole formed in the anti-rotation member is fitted into the projecting portion, and the support portion of the reel body The anti-rotation member is supported by being prevented from rotating.

  The support portion has an opening peripheral portion that is recessed in an end portion of the reel body surrounding the one-way clutch and opens outward in the axial direction, and a tongue piece portion in which the mounting hole is formed is in the opening peripheral portion. It is preferable to be accommodated in

  Further, a fixing member that prevents the axial movement of the one-way clutch is disposed outside the rotation prevention member, and a mounting hole formed in the fixing member is fitted into the protrusion, and a screw formed in the protrusion With the screw member screwed into the hole, the fixing member can be secured to the protrusion and fixed, and the one-way clutch and the rotation preventing member can be prevented from coming off from the support.

  A fishing reel having such a feature has a protrusion protruding from a support portion that accommodates a rolling one-way clutch, and the rotation preventing member is mounted on the reel by fitting a mounting hole of the rotation preventing member into the protruding portion. It is directly prevented by the main body and positioning of the anti-rotation member can be performed with high accuracy and stability, and the performance of the rolling one-way clutch can be prevented, and the assembly work is stabilized and the workability is improved. be able to.

  When the tongue piece portion of the rotation preventing member is accommodated in the opening peripheral portion formed in the support portion and opening in the axial direction, it is possible to reduce the size particularly in the axial direction and maintain stable strength.

  In addition, a fixing member that prevents the one-way clutch from moving in the axial direction is attached to the protrusion from the outside of the anti-rotation member, and the fixing member and the retaining member are screwed by a screw member that is screwed into a screw hole formed in the protrusion. In the case where the member is prevented from coming off from the support portion, the one-way clutch can be securely and stably held on the support portion of the reel body.

  1 to 8 schematically show a fishing reel according to a preferred embodiment of the present invention.

  As shown in FIGS. 1 and 2, the fishing reel of this embodiment is formed as a spinning reel, and this fishing spinning reel 10 has a side opening 14a of a rigid reel body 12a as a lid. The reel body 12 closed by 12b is provided, and the internal space S can be exposed to the outside by removing the fixing screw 16 of the lid 12b. Further, a notch 14b is formed on the rear end side of the reel body 12a, and the notch 14b is closed by a rear cap 18. By removing the fixing screw 20 of the rear cap 18, the notch 14b is also internally formed on the rear end side. The space S can be opened and closed. The reel body 12 is attached to a fishing rod (not shown) via a rod attachment portion 12d formed at an end portion of a leg portion 12c extending upward from the reel body 12a.

  In the reel body 12, a drive mechanism 24 for rotationally driving a hollow drive shaft 22 for driving a rotor, which will be described later, and a spool shaft 26 inserted into the hollow drive shaft 22 are provided in the same manner as a normal spinning reel. A known oscillating mechanism 28 that reciprocates in the front-rear direction with a constant stroke along the axial direction is accommodated, and a slider 28 a of the oscillating mechanism 28 is attached to the rear end portion of the spool shaft 26 by a set screw 30. It is fixed. The drive mechanism 24 and the oscillating mechanism 28 are operated in synchronization with each other by a handle shaft 34 having a handle 32 connected to one end.

  The handle shaft 34 of the present embodiment has a hollow structure and is rotatably supported by the reel body 12 via bearings 36a and 36b provided on the reel body 12a and the lid body 12b, respectively. The handle shaft 34 is integrally formed with a drive gear 34a described later. A female screw is formed at both ends of the handle shaft 34, and a distal end portion of a screw member 40 pivotally attached to the handle 32 with a pivot pin 38 is screwed into one end portion. It is installed by. Therefore, the handle shaft 34 forms a handle mounting portion together with the bearings 36a and 36b.

  The screw member 40 for mounting the handle 32 is inserted into the stand member 42. When the screw member 40 is tightened into the handle shaft 34 via the handle 32, the inner peripheral protrusion 42 a of the stand member 42 is moved to the handle shaft 34. The handle 32 and the stand member 42 are firmly fixed to the handle shaft 34 by the tightening force of the screw member 40. The stand member 42 separates the handle 32 from the reel body 12, and can freely rotate while preventing interference with the rotor described later. Further, the outer peripheral ridge 42b disposed on the outer peripheral side of the inner peripheral ridge 42a surrounds the annular protrusion 13a protruding from the reel body 12 with a slight gap, and foreign matter is contained in the internal space S of the reel body 12. Prevent intrusion.

  When the screw member 40 is loosened and a gap is formed between the stand member 42 and the handle 32, the handle 32 can be rotated around the pivot pin 38 to be in a folded state convenient for carrying or storage. By tightening the screw member 40 into the handle shaft 34 via the handle 32 from this folded state, it is possible to easily return to the fishing line winding state.

  In addition, a bearing cap 44 surrounding the annular protrusion 13b formed on the lid 12b is attached to the opposite side of the handle shaft 34 to prevent foreign matter from entering. By removing the bearing cap 44 and attaching the handle 32 and the stand member 42, the handle 32 can be freely changed from one side of the reel body 12 to the other side. In any case, by tightening the screw member 40 in the fishing line winding direction, the handle 32 and the handle shaft 34 can be integrated, and the fishing line can be wound up.

  In the internal space S of the reel body 12, a pinion 22 a that forms a drive mechanism 24 together with a drive gear 34 a that is formed integrally with the handle shaft 34 extends from the hollow drive shaft 22 that extends in a direction perpendicular to the handle shaft 34. The pinion 22a is formed on the outer peripheral portion, and is arranged in a state where it always meshes with the drive gear 34a. The hollow drive shaft 22 formed with the pinion 22a extends forward in the front portion F protruding forward from the handle mounting portion where the bearings 36a and 36b of the handle shaft 34 are arranged, and the rear end side close to the handle shaft 34 is located on the rear end side. It is supported by the reel body 12 via a bearing 46 a, and the front part is supported by a bearing 46 b disposed in the front portion F of the reel body 12, and the front end side protrudes from the front portion F, and is opposed to the reel body 12. It can rotate freely. The hollow drive shaft 22 guides a spool shaft 26, which is fitted with a spool 50 at the tip, in an axially penetrating inner hole so as to be slidable in the front-rear direction.

  The spool shaft 26 is formed with a non-circular section 26a and a threaded portion 26b in this order at the distal end protruding from the distal end side of the hollow drive shaft 22, and is attached to the non-circular section 26a via a stopper 48a. The formed spool 50 is detachably attached to the tip end portion of the spool shaft 26 by a tightening screw 48b formed in a cap nut shape.

  In the present embodiment, the stopper 48a is formed in a plate shape having an insertion hole corresponding to the non-circular portion 26a in the cross section, and is locked in a state in which the stopper 48a is prevented from rotating at the rear end portion of the non-circular portion 26a. That is, the movement to the reel body 12 side is prevented. The spool 50 is formed with flange portions 52a and 52b projecting radially outward on the front and rear of the barrel portion 52 having a cylindrical or tapered peripheral surface, and the front wall closing the front end side of the barrel portion 52. A short shaft portion 56 projects from the central portion of the portion 54 toward the rear opening side.

  An insertion hole having a cross-sectional shape corresponding to the cross-sectional non-circular part 26a passes through the short shaft part 56 in the axial direction, and is attached to the spool shaft 26 while being prevented from rotating on the cross-sectional non-circular part 26a. Then, the tightening screw 48b is fastened to the screw portion 26b, thereby being fastened and fixed to the stopper 48a.

  In addition, a large number of axial through holes 55 are formed at equal intervals in the front wall portion 54 where the short shaft portion 56 is disposed so as to surround the short shaft portion 56. These through-holes 55 are formed in a structure that reduces the weight of the spool 50 and reduces air resistance during fishing operations, and prevents the fishing line from entering the rear end side that opens outward. A skirt or inner flange 58 is formed. In addition, you may form many recessed grooves along the circumferential direction in the trunk | drum 52, and it can prevent that the fishing line wound around the spool 50 moves and loosens in this case.

  The tightening screw 48b for attaching the spool 50 to the spool shaft 26 minimizes the amount of protrusion from the front wall portion 54 in order to prevent the fishing line from being caught, and its peripheral portion is as smooth as possible. It is preferable to form by.

  The rotor 60 for winding the fishing line around the spool 50 has a peripheral wall portion 64 with a recess 62 opened rearward, and is connected to the hollow drive shaft 22 via a cylindrical drive portion 68 provided on the front wall portion 66. Is done. A pair of arm portions 70 project from the peripheral wall portion 64 surrounding the driving portion 68 radially outward at a rear opening end, that is, a portion facing the handle shaft 34 side in the radial direction. These arm portions 70, taper out along the axial direction of the spool shaft 26 from the rear opening end of the rotor 60 toward the front, and receive the body portion 52 of the spool 50 between the peripheral wall portion 64. Create a gap.

  The bail 72 attached to the tip of these arm portions 70 and 70 can be freely reversed between a fishing line winding position shown in FIG. 1 and a fishing line discharge position (not shown). One end of the bail 72 is attached to the arm part 70 via a support leg 73 fitted with a fishing line guide part 72a, and a fishing line winding position is provided by a distribution spring mechanism 74 schematically shown in part in FIG. 1 and the fishing line discharge position, and after the handle 32 is inverted in the direction of winding the fishing line, the bale 72 is manually returned to the fishing line winding position, or the fishing line winding shown in FIG. It automatically returns to the picking position. .

  In the front wall portion 66 of the rotor 60, axial through holes 65 are formed at equal intervals along the peripheral portion of the drive portion 68 (FIG. 2), and the outer peripheral portion of the front wall portion 66 includes, for example, The tubular guard ring 76 having a thin-walled structure that prevents the fishing line that has fallen inward from the rear of the spool 50 from entering the spool shaft is fixedly attached by means such as screwing or bonding in a state of protruding forward. . Further, the peripheral wall portion 64 surrounding the driving portion 68 is formed as a cylindrical portion whose front end side is closed by the front wall portion 66, and on the rear side from the front side with the bent portion 64 a at the intermediate portion in the axial direction interposed therebetween. The diameter is increased radially outward at a larger angle. An opening 63 that penetrates the peripheral wall 64 in the radial direction is formed at a portion adjacent to the rear opening of the peripheral wall 64, and the opening 63 is bent from the rear opening end of the peripheral wall 64. It extends along the axial direction while narrowing the opening width to the position on the front wall portion 66 side beyond 64a.

  The guard ring 76 is formed in an appropriate shape as long as it does not obstruct or block the air flow through the through holes 65 and 55 formed in the front wall portions 66 and 54 of the rotor 60 and the spool 50, respectively. It is possible to provide an opening around the periphery. Further, it can be integrated with the rotor 60.

  In the rotor 60 of the present embodiment, four radial openings 63 are formed to face each other in the radial direction at a portion adjacent to the rear opening end of the peripheral wall 64, and each arm 70 also has the peripheral wall 64. A radial opening 71 corresponding to the radial opening 63 is formed. The radial opening 71 of the arm 70 is arranged at a position aligned with the radial opening 63 of the peripheral wall 64 in the radial direction, and opens rearward. Therefore, the radial opening 71 formed in the arm 70 forms an opening continuous with the corresponding radial opening 63 of the peripheral wall 64. As a result, the front opening F of the reel body 12 disposed inside each of the radial openings 63 and 71 is largely exposed to the outside, and the lid 12b is externally exposed through the radial openings 63 and 71, for example. The fixing screw 16 can be tightened or removed.

  On the other hand, one of the two radial openings 63 formed between the arm portions 70 of the peripheral wall portion 64 is provided with an arc-shaped connecting piece 67 at the rear end thereof, and is integrally formed with the peripheral wall portion 64. Depending on the portion to be provided, the unbalanced members such as the bail 72 and the fishing line guide portion 72a can be balanced, and the rotor 60 can be smoothly rotated. Since the flange portion is not formed on the front portion F of the reel body 12, the bearing cap 44 protruding from the reel body 12 and the stand member 42 connected to the handle shaft 34 are reduced in shape, as in the prior art. The front portion F of the reel body 12 can be inserted into the concave portion 62 of the rotor 60 up to a position close to the rear end portion of the rotor 60, and the axial dimension of the fishing spinning reel 10 can be scaled. Can be shortened.

  The front portion F of the reel body 12 inserted into the concave portion 62 of the rotor 60 formed in this manner gradually decreases in the vertical direction from the leg portion 12c toward the front. In this specification, the front portion F of the reel body 12 is located at the front portion on the rotor 60 side of the handle mounting portion, that is, the portion where the bearings 36a and 36b for supporting the handle shaft 34 are arranged, unless otherwise specified. It refers to the portions of the reel body 12a and the lid 12b that are disposed. Accordingly, the leg portion 12c, the handle shaft 34, the stand member 42, and the bearing cap 44 that are disposed at positions substantially aligned with the bearings 36a and 36b in the vertical direction are not included in the front portion F.

  As shown in FIG. 2, in the front part F of the reel body 12, the front part of the hollow drive shaft 22 has a non-circular outer surface shape with respect to the pinion 22 a and prevents the drive part 68 of the rotor 60 from rotating. It forms as the operation | movement part 22b to fit, and the ball bearing which is the front side bearing 46b is mounted | worn with the rear-end part of this operation | movement part 22b. The inner ring of the bearing 46b is supported by the rear end of the operating portion 22b, and the outer ring is accommodated in an annular step 78a formed on the reel body 12a of the reel body 12, and is prevented from moving backward.

  3 to 6 show a support portion 80 which is formed in the cylindrical front portion F and arranges the rolling one-way clutch 82 in front of the bearing 46b.

  The support portion 80 of the present embodiment has a front stepped portion 78b formed at an inner diameter larger than the annular stepped portion 78a at the front end portion located in front of the annular stepped portion 78a that houses the front bearing 46b. A rolling one-way clutch 82 is accommodated in the front stepped portion 78b. The one-way clutch 82 includes an inner ring member 84 that is fixed to the operating portion 22b of the hollow drive shaft 22 and an outer ring member 86 that is fitted into the front stepped portion 78b via a protective cap 92 described later. A plurality of roller-shaped rolling members 88 held by the cage 88a are disposed between the rolling members 88, and the rolling members 88 can be moved between the free rotation region and the rotation regulating region by the cage 88a.

  As shown in FIG. 5, the retainer 88a has an operation arm 88b having an integral structure extending outward, and a switching cam 90 is connected to the operation arm 88b. The switching cam 90 is connected to an operating lever L (see FIG. 1) disposed at the rear end of the reel body 12 via an operating mechanism (not shown) extending in the front and rear directions in the reel body 12. , The retainer 88a is moved between the free rotation region and the rotation restricting region, and the reverse rotation preventing state for preventing the reverse rotation of the hollow drive shaft 22, that is, the rotor 60 in the fishing line feeding direction, It is possible to freely switch to a restriction release state that allows rotation and reverse rotation.

  The protective cap 92 disposed between the rolling one-way clutch 82 and the front stepped portion 78b is such that, for example, a stainless steel outer ring member 82 directly contacts the reel body 12a formed of, for example, a magnesium alloy or an aluminum alloy. And prevent corrosion due to electrochemical action. In particular, when the reel body 12a is made of a magnesium alloy, the protective cap 92 can be made of a material having a small potential difference from the magnesium alloy, for example, an aluminum material. By forming with a material, it is possible to reliably prevent the occurrence of electrolytic corrosion. In either case, the ear portion 92a is bent outward in the radial direction, and is fixed to the support portion 80 via a projection 98 described later, so that it can be easily positioned and held at a required position.

  Thus, the support part 80 which arrange | positions the rolling-type one-way clutch 82 protrudes radially outward between a pair of ear | edge parts 80a which protrude in a peripheral part from the site | part which opposes to radial direction, and these ear | edge parts 80a. An opening peripheral portion 94 having a cam housing portion 80b and recessed in the front end portion of the reel body 12 surrounding the one-way clutch 82 and opening outward in the axial direction is formed at the front end. The opening peripheral portion 94 is disposed in a plane perpendicular to the hollow drive shaft 22, the outer peripheral side is surrounded by the peripheral wall portion 96, and the inner peripheral side is a front step portion 78 b that houses the one-way clutch 82. And a step is formed between the opening end of the front step 78b.

  The opening peripheral portion 94 is connected to the switching cam 90 by the operating arm 88b of the retainer 88 in the cam housing portion 80b, and the operating mechanism for operating the switching cam 90 is an axial hole that opens to the opening peripheral portion 94. It extends rearward through 89 (FIG. 6). And in the ear | edge part 80a which opposes to radial direction, the protrusion 98 protrudes in an axial direction. The protrusion 98 has a cylindrical shape in which a screw hole 98a (FIG. 6) is formed along the axial direction, and protrudes forward of the reel body 12 beyond the peripheral wall portion 96 (see FIG. 3).

  As shown in FIGS. 3 and 5, in order to prevent the outer ring member 86 of the one-way clutch 82 from rotating with high accuracy, the engagement part 86 a formed on the peripheral edge of the outer ring member 86 of the one-way clutch 82 and the detent engagement. An anti-rotation member 100 is attached to the protrusion 98. Reference numeral 86b denotes a notch formed in the peripheral edge portion of the outer ring member 86, and the cam arm 80b does not interfere with the operating arm 88b integral with the retainer 88a via the notch 86b. Protrusively inside. When the anti-rotation member 100 is formed of metal, it is preferable to insert an ear portion 92a of the protective cap 92 between the opening peripheral portion 94 and prevent electrolytic corrosion.

  The anti-rotation member 100 includes a ring-shaped portion 102 having an outer diameter smaller than the inner diameter of the outer ring member 86, and a tongue piece portion 104 that protrudes from a portion facing the radial direction of the ring-shaped portion 102. A mounting hole 104a that fits into the portion 98 is formed. In this embodiment, a portion of the tongue piece 104 adjacent to the ring-shaped portion 102 is formed to be narrow and engaged in a state of being closely fitted to the engaging portion 86a of the outer ring member 86. As long as the movement of the member 86 can be prevented, such a narrow portion may not be used.

  In this way, the protrusion 98 protrudes from the opening peripheral edge portion 94 of the support portion 80 that accommodates the rolling one-way clutch 82, and the mounting hole 104 a of the rotation stopper member 100 is fitted into the protrusion 98, thereby preventing rotation. The member 100 is prevented from being directly rotated by the reel body 12, the positioning of the rotation preventing member 100 can be stably performed with high accuracy, and the deterioration of the performance of the rolling one-way clutch 82 can be prevented over a long period of time. It is stable and workability can be improved.

  In addition, the tongue piece 104 of the detent member 100 is accommodated in the opening peripheral edge portion 94 that opens in the axial direction in the ear portion 80a of the support portion 80, thereby achieving compactness in the axial direction and stable strength. Can be maintained.

  As shown in FIGS. 3 and 4, the one-way clutch 82 in which the outer ring member 86 is prevented from rotating with high precision by the rotation preventing member 100 is fixed by a fixing screw 106 that is screwed into the screw hole 98 a of the protrusion 98. The fixing member 108 is prevented from moving in the axial direction together with the anti-rotation member 100, and can be prevented from coming off from the support portion 80.

  The fixing member 108 of the present embodiment has an outer shape corresponding to the outer shape of the support portion 80, for example, is formed in a plate-like structure made of metal or hard resin, and includes a support portion including an ear portion 80a and a cam housing portion 80b. The peripheral edge portion of the front end portion of 80 is disposed so as to overlap the peripheral wall portion 96. A mounting hole 108a that is fitted to the outer peripheral surface of the protrusion 98 is formed in a portion of the support 80 that overlaps the ear 80a, and the fixing screw 106 is inserted into the screw hole 98a (FIG. 6) of the protrusion 98. By screwing, it is possible to prevent the fixing screw 106 from coming out of the protrusion 98 at the head.

  Further, the fixing member 108 has a central opening 110 formed to have a diameter slightly smaller than the inner diameter of the front stepped portion 78b. From the inner peripheral side of the central opening 110, it faces forward and radially inward. A seal member 114 with the lip 112 protruding in an inclined state is mounted on the opening peripheral edge 94 side. The lip portion 112 gradually decreases in thickness toward the tip, that is, the inner peripheral side, and the inner peripheral edge is rounded. As a result, regardless of the position of the lip portion 112, the inner periphery is slightly expanded and deformed and elastically engaged with the seal without causing damage to the outer periphery of the drive unit 68 of the counterpart rotor 60. Thereby, the inside of the front part F is sealed.

  The seal member 114 is formed with a thick portion 118 on the inner peripheral side of the flange portion 116 whose outer shape overlaps the outer shape of the fixing member 108, and from the outer surface side of the thick portion 118, that is, the side away from the opening peripheral edge portion 94. The lip portion 112 extends, and the flange portion 16 extends from the inner surface side. Further, the outer peripheral portion of the thick portion 118 is formed with a groove 120 into which the inner peripheral portion of the fixing member 108, that is, the peripheral portion of the central opening 110 is fitted.

  In the flange portion 116 of the seal member 114, a mounting hole 116a corresponding to the mounting hole 108a of the fixing member 108 is formed in the flange portion 116. The sealing member 114 is attached to the fixing member 108, and the outer shapes of both are aligned. When this is done, the mounting holes 108a and 116a are aligned on the same axis. FIG. 7 shows a state in which the seal member 114 is attached to the fixing member 108 as described above.

  When the fixing member 108 having the seal member 114 mounted thereon is placed on the peripheral edge portion 94 of the opening, the fixing screw 106 is screwed into the screw hole 98a of the protrusion 98 and tightened, the head of the fixing screw 106 is fixed. The flange portion 116 of the seal member 114, the tongue piece portion 104 of the anti-rotation member 100, and the ear portion 92 a of the protective cap 92 are pressed against the opening peripheral portion 94 through the member 108. Even when the anti-rotation member 100 and the fixing member 108 are formed of a hard material such as metal, the elastic force of the flange portion 116 of the seal member 114 can be securely tightened.

  As described above, the fixing member 108 that prevents the one-way clutch 82 from moving in the axial direction is attached to the projecting portion 98 from the outside of the anti-rotation member 100 and is screwed into a screw hole 98 a formed in the projecting portion 98. The fixing member 108 and the retaining member 100 are prevented from being detached from the support portion 80 by a certain fixing screw 106, so that the rolling one-way clutch 82 is securely and stably detached from the support portion 80 of the reel body 12. Can be stopped and held.

  Further, the peripheral edge portion of the central opening 110 of the fixing member 108 prevents axial movement through the outer ring member 88 of the rolling one-way clutch 82 together with the thick portion 118 of the seal member 114.

  By mounting the fixing member 108 on the opening peripheral edge portion 94 of the support portion 80, the front opening of the support portion 80 is closed by the seal member 114, and the seal by the seal edge portion 112 with respect to the outer peripheral side of the hollow drive shaft 22 is performed. It becomes possible, and the waterproofing in the support portion 80 of the reel body 12 can be reliably and easily performed by the elastic contact by the seal edge portion 112 without deteriorating the rotational performance of the hollow drive shaft 22.

Further, when the sealing member 114 is provided integrally with the fixing member 108, the sealing member 114 and the fixing member 108 can be handled as an integral member, and the efficiency of the assembling work can be greatly increased. According to the reel 10, the drive unit 68 disposed in the recess 62 that opens to the rear of the rotor 60 is integrally connected to the hollow drive shaft 22 that is driven by the drive mechanism 24 in the reel body 12. The seal member 114 disposed between the periphery of the portion 68 and the support portion 80 of the front portion F that accommodates the support portion that rotatably supports the hollow drive shaft 22 is held by the fixing member 108. By sealing the inside of the front portion F, there is no gap for foreign matter to enter, and the front portion F of the reel body 12 is reliably waterproofed and dust-proof. Further, since the seal member 114 is surrounded by the peripheral wall portion 64, the seal member 114 is reliably protected even when the spool 50 moves most forward.

  As a result, it is not necessary to provide a conventional flange portion in the reel body 12 for closing the rear opening end of the recess 62 of the rotor 60, and the front wall portions 66 and 54 of the rotor 60 and the spool 50 are penetrated. Since the holes 65 and 55 are formed, the air that has entered the recess 62 from the rear opening end of the rotor 60 can flow out to the outside through the through holes 65 and 55, and the air resistance is low. The fishing reel 10 can be reduced in weight and size.

  In particular, in a throw-only reel that competes for the flight distance to perform the fishing line release operation while swinging down with the fishing rod, it is easy to receive air resistance from the rear side of the reel body to the front side, and particularly the wind resistance during this fishing line release operation However, in addition to the flangeless structure of the front portion F of the reel body 12 as described above, the air generated by the rotor 60 and the through holes 65 and 55 of the spool is a factor that slightly decreases the fishing line discharge operability. The reduction in resistance makes it possible to improve the fishing line discharge operability, and can be used very suitably for a throw-only reel.

  In addition to the flangeless structure of the front portion F of the reel body 12, the peripheral wall portion 64 of the rotor 60 is further enlarged on the rear opening end side, so that the front portion F of the reel body 12 is close to the handle shaft 34. Even in the case where it is disposed in the recess 62 up to the position where it is positioned, the outer peripheral portion of the bearing cap 44 that protrudes from the side of the reel body 12, for example, attached to the lid 12 b, does not interfere with the rotor 60. The dimension in the axial direction can be shortened. Further, radial openings 63 and 71 are formed in the peripheral wall portion 64 and the arm portion 70 of the rotor 60, and the through-hole 65 is formed in the front wall portion 66, thereby reducing the weight of the rotor 60, It can rotate efficiently even with a small force. Further, the through hole 55 formed in the front wall portion 54 of the spool 50 also promotes weight reduction.

  Furthermore, foreign matters such as seawater, sand, and dust that have entered the recess 62 of the rotor 60 are washed from the outside with, for example, a shower, and easily washed away through the radial openings 63 and 71 and the through holes 55 and 65. In addition, the air permeability is improved, and moisture and foreign matters are not retained in the interior, thereby preventing corrosion and malfunction of the functional member.

  FIG. 9 shows a modification of the fixing member 108 and the seal member 114. In this modified example, the seal member 114 is integrated with the fixing member 108 by fixing means such as caulking, adhesion, and welding.

  The fixing member 108 may be fixed to the front surface, or a plurality of locations may be fixed as indicated by reference numeral 122. In this case, a protrusion 122 may be formed on the fixing member 108, and a small hole formed in the flange portion 116 of the seal member 114 may be fitted and fixed to the protrusion 122.

  Although the above-described embodiment or modification relates to a fishing spinning reel in which the flange portion of the reel body 12 is omitted, it is apparent that the present invention can be applied to other types of fishing reels.
