  Such fishing spinning reels are often used in harsh environments, especially when used on sandy beaches such as tossed fishing. It is very difficult to prevent sand and foreign matter from entering the reel body and adhering to the wall surfaces of these rotors located inside and the peripheral surface of the reel body. In particular, since the front part of the reel body is covered with the cylinder part of the rotor, it is impossible to check the adhesion of foreign matter such as sand that has entered the rotor, and the cleaning timing after fishing is missed. There is a risk that the front drive may be hindered.

  In addition, sand and foreign matter that enter the rotor often contain seawater depending on the fishing ground conditions. Corrosion is induced by covering the foreign matter containing seawater with the cylinder of the rotor. Or it is accelerated | stimulated and operation | movement performances, such as rotation of a rotor and a back-and-forth movement of a spool axis, and durability will be reduced.

  The present invention has been made based on such circumstances, and it is an object of the present invention to provide a fishing spinning reel that allows easy visual recognition of the inside of a rotor and enables easy operation.

The portion has a radial opening that allows the front portion of the reel body to be exposed in a peripheral wall portion surrounding the front portion of the reel body.

  According to such a spinning reel for fishing, the inside of the rotor and the front portion of the reel body can be easily visually recognized through the radial opening formed in the peripheral wall portion of the rotor. Improves ventilation and circulation of the rotor through the opening, so that even when sand or foreign matter enters the inside, it can be easily removed and cleaned without missing the time required for cleaning. Can be maintained. Furthermore, the radial opening not only reduces the weight of the rotor, but also locks the fishing line via its edge, so that the fishing line that has fallen from the rear of the spool enters the inside of the spool and the front part of the rotor and the spool. It is possible to prevent the fishing line from being entangled and thereby to easily perform the discharge and winding operation of the fishing line.

Furthermore , an annular space that communicates the recess with the outside is formed on the rear opening end side of the cylindrical portion of the rotor between the cylindrical portion and the front portion of the reel body, so that even a simple washing means such as a shower can be used. , Sand, dust, dirt, etc. that have entered and adhered to the inside can be easily washed off through the radial opening and the rear opening end, further improve the ventilation in the recess, suppress internal retention, and No flange is required, and the weight is reduced by the opening formed in the peripheral portion of the rotor, and the fishing operability can be improved.

  As shown in FIGS. 1 and 2, a fishing spinning reel 10 includes a reel body 12 in which a side opening 14a of a reel body 12a formed of, for example, metal in a rigid structure is closed with a lid 12b. The internal space S can be exposed to the outside by removing the fixing screw 16 of the body 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 the spool shaft 26, which is fitted with the 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.

  In the short shaft portion 56, an insertion hole having a cross-sectional shape corresponding to the cross-sectional non-circular portion 26a penetrates in the axial direction. The short shaft portion 56 is attached to the spool shaft 26 in a state where the short shaft portion 56 is prevented from rotating on the non-circular portion 26a, and the tightening screw 48b is fastened to the screw portion 26b, whereby the spool 50 is stopped via the short shaft portion 56. Tightened and fixed to.

  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 cylindrical portion 60A having a recess 62 opened rearward. The cylindrical portion 60A is formed by a peripheral wall portion 64 and a front wall portion 66, and the front wall It is integrally connected to the distal end portion of the hollow drive shaft 22 via a thick sleeve-like drive portion 68 protruding from the portion 66 into the recess 62. A pair of arm portions 70, 70 that form the rotor 60 together with the cylindrical portion 60 </ b> A at the rear opening end, that is, the portion facing the handle shaft 34 side in the radial direction is formed on the peripheral wall portion 64 surrounding the drive portion 68. Projected to These arm portions 70 and 70 extend in a tapered manner along the axial direction of the spool shaft 26 from the rear opening end of the cylindrical portion 60 </ b> A toward the front, and the body portion 52 of the spool 50 is interposed between the peripheral wall portion 64 and the arm portion 70. Create a receiving gap.

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 driving portion 68. For example, the outer peripheral portion of the front wall portion 66 has, for example, a spool 50. A thin-walled cylindrical guard member 76 that prevents the fishing line that has fallen inward from the rear from being wound around the spool shaft is attached and fixed by means of screwing, bonding, or the like in a state of protruding forward. A locking piece 76a for preventing the fishing line from dropping off toward the spool shaft 26 is provided on the outer peripheral portion on the front end side. Further, the peripheral wall portion 64 that forms the cylindrical portion 66A together with the front wall portion 66 on the front end side is directed radially outward at a larger angle on the rear side than on the front side, with the bent portion 64a of the intermediate portion in the axial direction interposed therebetween. To expand the diameter. 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 member 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. As shown in FIG. 3, for example, a large number of blade members 77 may be arranged radially around the periphery, and openings 75 may be provided between these adjacent blade members. A locking piece 76 a for locking the fishing line can be provided at the tip of these blade members 77. Further, the guard member 76 can be integrated with the rotor 60.

  As best shown in FIG. 3, the rotor 60 of the present embodiment is formed such that four radial openings 63 are opposed to each other in the radial direction at a portion adjacent to the rear opening end of the peripheral wall 64. A radial opening 71 corresponding to the radial opening 63 of the peripheral wall 64 is also formed in the arm 70. 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 80 of the reel body 12 disposed inside each of the radial openings 63 and 71 is largely exposed to the outside, and the lid body 12b is externally provided via the radial openings 63 and 71, for example. The fixing screw 16 can be tightened or removed.

  On the other hand, the two radial openings 63 formed between the arm portions 70 of the peripheral wall portion 64 are provided with an arc-shaped connecting piece 67 at the rear end portion. At the rear opening end of the cylindrical portion 60 </ b> A in which these connecting pieces 67 extend in the circumferential direction between the pair of arm portions 70, an annular space A that communicates the concave portion 62 with the outside is accommodated in the peripheral wall portion 64 and the concave portion 62. It is formed between the front part F of the reel body 12. Thereby, for example, even with simple water washing means such as a shower, it is possible to directly apply this shower to the foreign matter adhered to the outer surface of the front portion F of the reel body 12, and the sand that has entered the concave portion 62 and adhered thereto, Dust, dirt and the like can be easily washed off through the openings 63 and 71 and the annular space A at the rear opening end. Furthermore, the ventilation in the recessed part 62 is also favorable and the inconvenience by an internal residence can also be eliminated. Further, the conventional flange is not required, and the weights are reduced by the openings 63 and 71 formed in the peripheral portion of the rotor 60, that is, the peripheral wall portion 64 and the arm portion 70, and the fishing operability can be improved.

  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. Reference numeral 69 denotes a nut member that fastens and fixes the drive unit 68 to the operating unit 22b. By tightening the nut member 69 on the outer periphery of the operating unit 22b, a hollow drive is performed via an inner ring member 86 and a bearing 46b, which will be described later. It is fastened and fixed to a step formed on the outer periphery of the shaft 22.

  FIG. 4 shows a support portion 80 that is formed in the cylindrical front portion F and supports the hollow drive shaft 22.

  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 type one-way clutch 82 is accommodated and supported in the front stepped portion 78b. The one-way clutch 82 is formed between an inner ring member 84 that is prevented from rotating by the operating portion 22b of the hollow drive shaft 22 and an outer ring member 86 that is fitted in the front stepped portion 78b through a protective cap 92. A plurality of roller-shaped rolling members 88 held by the retainer 88a are arranged in the roller 88a, and the rolling member 88 can be moved between the free rotation region and the rotation restricting region by the retainer 88a. The outer ring member 86 is prevented from rotating in the support portion 80 by the rotation preventing member 90.

  An operating arm (not shown) protrudes radially outward from the retainer 88a, and the operating arm (not shown) extending forward and backward in the reel body 12 is connected to the rear end of the reel body 12 through the operating arm. The arranged operation lever L (see FIG. 1) is connected. By switching the operation lever L, the retainer 88a is moved between the free rotation region and the rotation restriction region, and the reverse rotation prevention that prevents the hollow drive shaft 22, that is, the rotor 60 from rotating in the fishing line feeding direction is prevented. It is possible to freely switch between a state and a restriction release state that allows forward rotation and reverse rotation.

  The protective cap 92 disposed between the rolling one-way clutch 82 and the inner peripheral surface of the front stepped portion 78b is a reel body in which an outer ring member 82 made of, for example, stainless steel is formed of, for example, a magnesium alloy or an aluminum alloy. Direct contact with 12a to 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 with respect to 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 92a is bent outwardly in the radial direction, and is fixed to the support 80 via a protrusion 94 described later, so that it can be easily positioned and held at the required position.

  In this way, the support portion 80 on which the rolling one-way clutch 82 is arranged has an opening peripheral portion 96 at the tip which is recessed in the tip of the reel body 12 surrounding the one-way clutch 82 and opens outward in the axial direction. It is. The opening peripheral portion 96 is disposed in a plane perpendicular to the hollow drive shaft 22, the outer peripheral side is surrounded by the peripheral wall portion 98, 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.

  Within the opening peripheral portion 96 surrounded by the peripheral wall portion 98, the operating arm of the retainer 88 is connected to the operating mechanism operated by the operation lever L, and the rotation preventing member 90 that prevents the rotation of the outer ring member 86 is accommodated. The And in the ear | edge part 80a which opposes to radial direction, the protrusion 94 protrudes in an axial direction. The protrusion 94 has a cylindrical shape in which a screw hole 94 a is formed along the axial direction, and protrudes forward of the reel body 12 beyond the peripheral wall portion 98.

  The anti-rotation member 90 has a pair of mounting holes 90a that fit into the protrusions 94, and the anti-rotation member 90 is prevented from being directly rotated by the reel body 12 by fitting the mounting holes 90a into the protrusions 94. Therefore, the rotation-preventing member 90 can be positioned with high accuracy and stability, and the performance of the rolling one-way clutch 82 can be prevented over a long period of time, and the assembly work can be stabilized and the workability can be improved. Can do. Further, the rotation preventing member 90 is accommodated in the opening peripheral edge portion 96 that opens in the axial direction in the ear portion 80a of the support portion 80, so that it is possible to reduce the size particularly in the axial direction and maintain stable strength. it can.

  The one-way clutch 82 in which the outer ring member 86 is prevented from rotating with high precision by the rotation preventing member 90 is secured by a fixing member 102 that is fixed by a fixing screw 100 that is screwed into the screw hole 94a of the protrusion 94. At the same time, the movement in the axial direction is prevented and the supporting portion 80 can be prevented from coming off.

  The fixing member 102 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 is formed at the front end portion of the support portion 80 including the ear portion 80a. The peripheral edge portion is disposed so as to overlap the peripheral wall portion 98. A mounting hole 102a that is fitted to the outer peripheral surface of the protrusion 94 is formed in a portion that overlaps the ear 80a of the support portion 80, and the fixing screw 100 is screwed into the screw hole 94a of the protrusion 94. Thus, it is possible to prevent the head of the fixing screw 100 from coming out of the protrusion 94.

  Further, the fixing member 102 has a seal edge portion 104a inclined forward and radially inward from the inner peripheral side of the central opening formed slightly smaller than the inner diameter of the front step portion 78b. The protruding seal member 104 is mounted on the opening peripheral edge 96 side. The seal edge portion 104 a gradually decreases in thickness toward the tip, that is, the inner peripheral side, and the inner peripheral edge portion is rounded to form a seal lip portion for the drive unit 68. As a result, regardless of the position of the seal edge 104a, the inner circumference is slightly expanded and elastically engaged with the seal without elastically damaging the outer circumference of the drive section 68 of the other rotor 60. Thereby, the inside of the front part F is sealed.

  The seal member 104 is formed with a thick portion 104c on the inner peripheral side of the flange portion 104b whose outer shape overlaps the outer shape of the fixing member 102, and from the outer surface side of the thick portion 104c, that is, the side away from the opening peripheral portion 96. The seal edge portion 104a extends, and a flange portion 104b that overlaps the fixing member 102 extends from the inner surface side. A groove 104d into which the inner peripheral edge of the fixing member 102 is fitted is formed on the outer peripheral portion of the thick portion 104c.

  A mounting hole corresponding to the mounting hole 102a of the fixing member 102 is formed in the flange portion 104b of the sealing member 104. When the sealing member 104 is mounted on the fixing member 102 and the outer shapes of both are aligned, The respective mounting holes are aligned on the same axis and can be fitted into the protrusion 94. The seal member 104 can elastically deform the groove 104 d to remove the peripheral portion of the central opening of the fixing member 102, and the sealing member 104 can be attached to and detached from the fixing member 102.

  When the fixing member 102 having the seal member 104 mounted thereon is placed on the peripheral edge portion 96 of the opening and the fixing screw 100 is screwed into the screw hole 94a of the protrusion 94 and tightened, the head of the fixing screw 100 is fixed. The flange portion 104 b of the seal member 104, the anti-rotation member 90, and the ear portion 92 a of the protective cap 92 are pressed against the opening peripheral portion 96 through the member 102. The flange portion 104b of the seal member 104 acts as a base portion of the seal member 104 that comes into contact with the opening peripheral edge portion 96 to seal the reel body 12 side, and due to its elasticity, the anti-rotation member 90 and the fixing member 102 are made of a hard material such as metal. Even when formed of a material, it can be securely tightened.

  Thus, the fixing member 102 that prevents the one-way clutch 82 from moving in the axial direction is attached to the protruding portion 94 from the outside of the anti-rotation member 90 and is screwed into the screw hole 94a formed in the protruding portion 94. The fixing member 102 and the rotation preventing member 90 are prevented from coming off from the support portion 80 with a certain fixing screw 100, so that the rolling one-way clutch 82 can be 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 of the fixing member 102 is prevented from moving in the axial direction through the outer ring member 86 of the rolling one-way clutch 82 together with the thick portion 104 c of the seal member 104.

  By attaching the fixing member 102 to the opening peripheral edge 96 of the support portion 80, the front opening of the support portion 80 is closed by the seal member 104, and the seal edge 104a seals the outer periphery of the hollow drive shaft 22. 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 104a without deteriorating the rotational performance of the hollow drive shaft 22.

Further, when the seal member 104 is provided integrally with the fixing member 102, the seal member 104 and the fixing member 102 can be handled as an integral member, and the efficiency of the assembling work can be extremely increased. When assembling the rotor 60 to 80, a drive portion 68 protruding into the recess 62 of the rotor 60 is attached to the tip of the operating portion 22 b of the hollow drive shaft 22 protruding from the support portion 80. The seal edge 104a of the seal member 104 is engaged with the seal member 104, and a tightening nut 69 (see FIG. 2) is screwed into a screw portion (not shown) formed at the tip of the operating portion 22b. By tightening the tightening nut 69, the front end surface of the inner ring member 84 of the one-way clutch 82 that functions as a spacer is pressed on the rear end surface of the drive unit 68, and the rotor 60 and the hollow drive shaft 22 are integrally coupled. . When the guard member 76 is formed separately from the rotor 60, the guard member 76 is attached to the outer peripheral portion of the front wall portion 66 by screwing or the like.

  Thereafter, the stopper 48a is attached to the non-circular portion of the cross section of the spool shaft 26, and the spool 50 receives the guard member 76 and the cylindrical portion 60A of the rotor 60 from the rear end side opening portion, and the peripheral wall portion 64 and the arm portion 70. The body portion 52 is inserted into the gap between the short shaft portion 56, the short shaft portion 56 is brought into contact with the stopper 48a, the tightening screw 48b is fastened to the screw portion 26b, and the spool is fixed to the spool shaft 26. Assembling of the spinning reel 10 is completed.

  As a result, the drive unit 68 disposed in the recess 62 opened to the rear of the rotor 60 is integrally connected to the hollow drive shaft 22 driven by the drive mechanism 24 in the reel body 12. A seal member 104 disposed between the periphery and the support portion 80 of the front portion F that accommodates a support portion that rotatably supports the hollow drive shaft 22 seals the inside of the front portion 80 of the reel body 12. 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 104 is surrounded by the peripheral wall portion 64, the seal member 104 is reliably protected even when the spool 50 moves most forward.

  Therefore, according to the spinning reel 10 for fishing of the present embodiment, the state of the inside of the rotor 60 and the front portion F of the reel body 12 can be easily achieved through the radial opening 63 formed in the peripheral wall portion 64 of the rotor 60. Furthermore, sand and foreign matter have entered the inside of the rotor 60 through the radial opening 63, for example, by improving the ventilation and circulation of the rotor 60 without missing the time required for cleaning. Even in this case, it is difficult to be fixed, can be easily removed, and a clean state can be maintained. Further, in addition to reducing the weight of the rotor 60, the radial opening 63 locks the fishing line via the edge thereof, and the fishing line that has fallen from the rear of the spool 50 enters the inside of the spool 50 and enters the rotor 60. It is possible to prevent the fishing line from being entangled with the front portion and the spool shaft 26, thereby enabling the fishing line to be released and wound up easily.

  An annular space A is formed at the rear opening end of the concave portion 62 of the rotor 60, and it is not necessary to provide a conventional flange portion for closing the annular space A in the reel body 12, and each of the rotor 60 and the spool 50 is provided. By forming the through holes 65 and 55 in the front wall portions 66 and 54, the air that has entered the recess 62 in the cylindrical portion 60 </ b> A of the rotor 60 flows out through the through holes 65 and 55. Therefore, the fishing reel 10 can have a low air resistance and can be reduced in weight and size. Further, due to the flangeless structure of the reel main body 12, the bearing cap 44 protruding from the reel main body 12 and the stand member 42 connected to the handle shaft 34 can be arranged without being restricted by the conventional shape. Accordingly, for example, the front portion F of the reel body 12 can be inserted into the concave portion 62 of the rotor 60 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 reduced. It can be shortened as much as possible.

  In particular, in a throw-only reel that competes for a flight distance in which a fishing line discharge operation is performed while swinging down together with a fishing rod, it is easy to receive air resistance from the rear side of the reel body 12 to the front side. The resistance is a factor that slightly lowers the fishing line discharge operability. In addition to the flangeless structure of the front portion F of the reel body 12 as described above, the resistance is caused by the rotor 60 and the through holes 65 and 55 of the spool. The reduction in air resistance and downsizing can 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.

  Further, foreign matter such as seawater, sand, and dust that has entered the recess 62 of the rotor 60 is washed from the outside with, for example, a shower or the like, and is passed through the annular space A, the radial openings 63 and 71, and the through holes 55 and 65. While being able to wash away easily, air permeability becomes good, and a stay of a water | moisture content, a foreign material, etc. also lose | eliminates inside, and it can prevent the induction | guidance | derivation of a corrosion and the malfunction of a functional member.

  Further, when the cylindrical portion 60A of the rotor 60 receives the front portion F of the reel body 12, the rotational position of the circumferential wall portion 64 and the radial openings 63 and 71 of the arm portion 70 can be freely set only by rotating the rotor 60. Since it can move, water that has flowed into the inside can be easily discharged to the outside, and foreign substances such as sand and dust that have accumulated inside the recess 62 can be directly discharged through the radial openings 63 and 71. Can be washed away.

  An annular space A that communicates the recessed portion 62 to the outside at the circumferential wall portion 64 where the recessed portion 62 of the rotor 60 opens, that is, the rear opening end of the cylindrical portion, is between the circumferential wall portion 64 and the front portion 80 of the reel body 12. With this, even with simple water washing means such as a shower, it is possible to directly apply this shower to the foreign matter adhering to the outer surface of the front portion 80 of the reel body 12, and the inside of the recess 62 is invaded. Adhering sand, dust, dirt and the like can be easily washed off through the openings 63 and 71 and the rear opening end. Furthermore, the ventilation in the recessed part 62 is also favorable and the inconvenience by an internal residence can also be eliminated. Further, the conventional flange is not required, and the weights are reduced by the openings 63 and 71 formed in the peripheral portion of the rotor 60, that is, the peripheral wall portion 64 and the arm portion 70, and the fishing operability can be improved.
