Description

  The present invention relates to a spinning reel for fishing, in which a rotor having a fishing line guide portion is rotationally driven via a handle provided on a reel body, and a fishing line is wound around a spool.

  Usually, a fishing spinning reel rotates a rotor in conjunction with a handle operation, and a spool that moves back and forth in the axial direction in conjunction with the rotation of the rotor via a fishing line guide provided on the rotor. It winds a fishing line. In such spinning reels, the spool has a longer stroke for the purpose of increasing the bobbin winding capacity and improving the fishing line discharge performance.For this reason, the spool is opened in the space part of the spool that opens rearward and in the front part of the rotor. A so-called out-spool type spinning reel, in which the formed cylindrical portion is inserted deeply and the spool is exposed to the outside, is the mainstream.

  And the cylindrical part of the rotor arrange | positioned in such a spool is connected with a rotational drive shaft through a radial direction wall part, and guides a fishing line to the rear cylindrical part of the back side rather than this radial direction wall part. The base part of the pair of arms that arranges the bale and the fishing line guide part at the tip part protrudes in the radial direction, and the front cylindrical part on the front side is formed in a reverse taper shape with the diameter expanded toward the front. The fishing spinning which prevents the fishing line which entered inside from the opening of the rear side of the spool from being caught in the spool shaft which moves back and forth by forming an annular hook portion at the front end portion of the front cylindrical portion A reel has been developed (see, for example, Patent Document 1).

JP 2002-153173 A

  Such a fishing spinning reel has a bottomed cylindrical structure in which the front cylindrical portion of the rotor opens forward and the radial wall portion forms the bottom wall, and the spool opens rearward. By forming the bottom cylindrical structure, when the cylindrical portion of the rotor reciprocates back and forth in the spool, air resistance due to air accumulation or retention between the spool and the cylindrical portion of the rotor, Phenomenon such as abnormal noise occurs. For this reason, comfortable winding operation property falls.

  In addition, if a change in the tension of the fishing line, a thread dandruff, a thread twist, etc. occur during the winding operation, this is induced, and the fishing line enters the inner cylindrical portion from the rear of the spool, and the spool shaft that reciprocates the spool. The thread entanglement phenomenon due to so-called thread dropping easily occurs, and the above-described reverse tapered shape of the front cylindrical part and the annular hook part at the front end part can hook the fishing line at a part of the outer peripheral part of the front cylindrical part. Even in this case, the yarn twist phenomenon occurs, and further, it is not possible to effectively prevent the fishing line from dropping in a direction in which the dropping direction is not constant.

  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 capable of effectively preventing a drop of a fishing line and performing a comfortable winding operation. .

  A fishing spinning reel of the present invention that achieves the above object includes a rotor body that moves in and out of a spool that moves back and forth in the axial direction, an arm portion that extends from the rear end side of the rotor body, and the arm portion. A fish that has a rotor having a fishing line guide provided on the reel and rotates the rotor through a handle provided on the reel body so that the fishing line is wound around the spool via the fishing line guide provided on the arm. A spinning reel for fishing, wherein an uneven outer peripheral portion in which a plurality of concave portions and a plurality of convex portions are arranged along a circumferential direction is formed in a front portion of the rotor body.

  It is preferable to have a projection protruding outward in the radial direction at the front end portion of the convex portion.

  Moreover, it is preferable that the said rotor has a through-hole aligned with the said recessed part to an axial direction in the wall part couple | bonded with a drive shaft.

  Furthermore, the rotor body may have a radial opening on the rear end side.

  According to such a spinning reel for fishing, a plurality of recesses formed on the outer periphery of the concave and convex portions of the rotor allow the air to freely enter and exit from the inside and outside of the spool when the spool moves back and forth. Prevents the occurrence of air resistance and abnormal noise due to the accumulation of air or staying in the inside, and furthermore, the plurality of recesses and projections form a fishing line locking function, thereby preventing line dropping from all directions, Thereby, a spinning reel for fishing is provided that can effectively prevent the line from dropping off and can perform a comfortable winding operation.

  When a protrusion protruding outward in the radial direction is formed at the front end portion of the convex portion, the protrusion locks the fishing line, thereby reliably preventing the thread from dropping.

  In addition, when the rotor body has through holes that are axially aligned with the recesses in the connecting wall portion that is coupled to the drive shaft, foreign matters such as water that have entered the rotor body It can be discharged to the outside through the recess, and corrosion or deterioration of the function of the member arranged in the rotor body can be prevented.

  Furthermore, when the rotor body has a radial opening on the rear end side, suitable air permeability is obtained from the front part to the rear part of the rotor body, and internal retention of moisture and air is reliably prevented, and after fishing Maintenance work such as washing with water can be done easily and easily.

The figure which looked at the rotor body of FIG. 1 from the front. The perspective view of the rotor of the spinning reel for fishing of FIG. The figure similar to FIG. 1 of the spinning reel for fishing by other embodiment.

  1 to 4 schematically show a fishing spinning reel 10 according to a preferred embodiment of the present invention.

  As shown in FIG. 1, a fishing spinning reel 10 includes a reel body 12 in which a side opening 14a of a rigid reel body 12a is closed by a lid 12b, and a fixing screw 16 of the lid 12b is removed. Thus, the internal space S can be exposed to the outside. 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 fishing spinning reel 10 is attached to a fishing rod through legs (not shown) extending upward from the reel body 12a, as usual.

  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 that reciprocates back and forth with a constant stroke along the axial direction is accommodated, and a slider 28 of this oscillating mechanism is fixed to the rear end of the spool shaft 26 with a set screw 30. ing. The drive mechanism 24 and the oscillating mechanism 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 formed integrally with the handle shaft 34 is an outer periphery of the drive shaft 22 that extends in a direction perpendicular to the handle shaft 34. The pinion 22a 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 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 has the bearing 46a. The front part is supported by a bearing 46b arranged in the front part of the reel body 12, and the front end protrudes from the front part and can freely rotate with respect to the reel body 12. it can. 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 that winds the fishing line around the spool 50 has a rotor body 62 that goes in and out of the spool 50 through the rear opening end when the spool 50 moves back and forth along the axial direction. The rotor body 62 has a rear concave portion 62a that opens to the rear and a front concave portion 62b that opens to the front, and is provided on a connecting wall portion 66 that extends in the radial direction at the front end portion of the peripheral wall portion 64 that surrounds the front portion of the reel body 12. It is connected to the hollow drive shaft 22 via a cylindrical drive part 68. Further, the rotor 60 has a pair of arm portions 70 and 70 extending from a rear opening end of the peripheral wall portion 64, that is, from a radially opposed portion on the handle shaft 34 side. 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 peripheral wall portion 64 toward the front, and the body portion 52 of the spool 50 is disposed between the arm portion 70 and the rotor body 62. Create a receiving 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 and a fishing line release are provided by a distribution spring mechanism 74 schematically showing a part thereof. The bail 72 is manually returned to the fishing line winding position, or is automatically returned to the fishing line winding position by a reverse return mechanism (not shown). .

  Further, the peripheral wall portion 64 of the rotor body 62 is closed at the front end side by the connecting wall portion 66, accommodates the drive portion 68 in the rear concave portion 62 a, and sandwiches the bent portion 64 a of the intermediate portion in the axial direction from the rear side. The diameter is increased radially outward at a larger angle. A radial opening 63 (see FIG. 4) that penetrates the peripheral wall 64 in the radial direction is formed in a portion adjacent to the rear opening end of the peripheral wall 64, and the radial opening 63 is a peripheral wall. It extends along the axial direction while narrowing the opening width from the rear opening end of the portion 64 to the position on the connecting wall portion 66 side beyond the bent portion 64a.

  An axial through-hole 65 is formed in the connecting wall portion 66 of the rotor 60 along the peripheral portion of the driving portion 68 (FIG. 3), and the rotor together with the peripheral wall portion 64 is provided on the front side of the connecting wall portion 66. The front cylindrical portion 76 that forms the body 62 is fixed, and prevents, for example, a fishing line that has fallen inward from the rear of the spool 50 from being caught in the spool shaft 26.

  As shown in enlarged views in FIGS. 2 and 3, the front cylindrical portion 76 includes a mounting wall portion 78 placed on the front end surface of the connecting wall portion 66 and a cylindrical wall extending forward from the mounting wall portion 78. 80. The cylindrical wall 80 is closed at the rear end side by the mounting wall portion 78 and opens the front recess 62 forward.

  An insertion hole 78 a through which the spool shaft 26 and the drive shaft 22 are inserted is formed in the mounting wall portion 78 that forms the bottom wall of the front cylindrical portion 76, and is connected by a fixing screw 67 through the mounting wall portion 78. Fixed to the wall 66. The inner peripheral surface of the insertion hole 78a is formed in a polygonal shape, and can prevent rotation of a tightening nut described later. Further, it is preferable that the flange portion 78b protrudes from the inner peripheral surface of the cylindrical wall 80 to prevent foreign matter from entering between the tightening nut and the insertion hole 78a.

  The cylindrical wall 80 of the front cylindrical portion 76 has an inner diameter of the front recess 62b larger than that of the stopper 48a so as not to interfere with the spool 50 or the stopper 48a supporting the spool 50 when the spool 50 moves rearward. A plurality of concave portions 82 and a plurality of convex portions 84 are alternately formed in the outer peripheral portion along the circumferential direction. The concave portion 82 and the convex portion 84 form a concave / convex outer peripheral portion C in the front portion of the rotor body 62, and the plurality of concave portions 82 and the convex portions 84 forming the concave / convex outer peripheral portion C form a fishing line locking function. By doing so, the thread drop from any direction is prevented.

  The convex portion 84 of the present embodiment is formed in a blade shape arranged at substantially equal intervals along the peripheral portion of the cylindrical portion 80, extends in the axial direction and the radial direction, and forms the concave portion 82 therebetween. In the illustrated embodiment, eight blade-like convex portions 84 arranged radially and eight concave portions 82 arranged between these convex portions 84 are formed. As a result, the fishing line that has entered from various directions is likely to be caught on the side surfaces and corners of the convex portion 84, and the slackened fishing line is held in the concave portion 82, so that it enters the inside from the opening on the rear side of the spool 50. It is possible to effectively prevent the yarn entanglement phenomenon caused by the thread dropping inside the fishing line. The number and shape of these convex portions 84 and concave portions 82 can be changed as appropriate.

  Each convex portion 84 has an outer peripheral edge formed in an inversely tapered shape, that is, an inclined surface that is reduced in diameter toward the spool shaft 26 toward the rear, and prevents the fishing line from moving further forward. Further, a projection 86 protruding radially outward is provided at the front end portion of each convex portion 84, and the fishing line can be locked by this projection 86, thereby preventing the line drop more reliably. .

  In FIG. 4, the outer peripheral side edges of the protrusions 84 and the protrusions 86 are formed as flat surfaces for the sake of clarity, but are shown in FIG. 3 in order to prevent the contacted fishing line from being damaged. It is preferable to form with such a curved surface.

  As shown in FIG. 3, the concave portion 82 formed on the outer peripheral side of the front cylindrical portion 76 extends in the axial direction, and a through hole 65 that is aligned with the concave portion 82 in the axial direction is formed in the connecting wall portion 66. Furthermore, the through holes 55 formed in the front wall portion 54 of the spool 50 can also be arranged in alignment with the concave portions 82 and the through holes 65 in the axial direction. These concave portions 82 and through holes 65 and 55 allow the skirt 58 of the spool 50 and the peripheral wall portion of the rotor body 62 to freely enter and exit the inside and outside of the spool 50 when the spool 50 moves back and forth. Even in the case where the clearance between the spool 64 and the spool 64 is small, air resistance or abnormal noise due to air accumulation or retention in the spool 50 is prevented. Further, foreign matters such as water that have entered the front cylindrical portion 76 and the peripheral wall portion 64 of the rotor body 62 can be discharged to the outside through the through holes 65 and 55 and the recess 82. Corrosion or functional deterioration of the disposed seal member or the like, which will be described later, can be prevented.

  As best shown in FIG. 4, the rotor body 62 of the present embodiment is formed with four radial openings 63 opposed in the radial direction at a portion adjacent to the rear opening end of the peripheral wall 64. Each arm 70 is also formed with a radial opening 71 corresponding to the radial opening 63 of the peripheral wall 64. 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 88 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, 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 69 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 88 of the reel body 12 with respect to the bearing cap 44 protruding from the reel body 12 and the stand member 42 connected to the handle shaft 34, the conventional geometrical constraints are reduced. The front portion 88 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.

  As shown in FIG. 1, the front portion 88 of the reel body 12 inserted into the rear recess 62a of the rotor 60 formed in this manner gradually decreases in the vertical direction toward the front. In this specification, the front portion 88 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 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.

  Inside the front portion 88 of the reel body 12, the front portion of the hollow drive shaft 22 has a non-circular cross-sectional outer surface shape and serves as an operation portion 22b that prevents the drive portion 68 of the rotor 60 from rotating. The ball bearing which is the front bearing 46b is attached to the rear end portion of the operating portion 22b.

  Further, in the cylindrical front portion 88, as shown in an enlarged view in FIG. 2, a one-way clutch 92 is attached to the front of the bearing 46b via a spacer 90, and between the presser plate 94 and the retainer 96. A set screw 100 for fixing the inserted seal member 98 to the front end surface of the reel body 12a prevents the seal member 98 from being pulled forward. The bearings 46b and the one-way clutch 92 are stepped portions formed on the inner surface side of the reel body 12a, locking the outer peripheral side rear end portion and being prevented from moving backward. Therefore, the front end portion of the front portion 88, that is, the portion accommodating the bearing 46b and the one-way clutch 92 supports the hollow drive shaft 22 in the front portion 88 so as to be rotatable while preventing axial movement.

  The one-way clutch 92 disposed at the front portion 88 is operated by switching a known operation lever L (not shown) disposed at the rear end portion of the reel body, so that the hollow drive shaft 22 in the fishing line feeding direction is switched. In other words, it is possible to freely switch between a reverse rotation preventing position for preventing reverse rotation of the rotor 60 and a restriction release position for allowing normal rotation and reverse rotation.

  As shown in FIG. 2, the seal member 98 has an annular lip portion 98 b that extends from the inner peripheral side of the annular base portion 98 a pressed by the annular retainer 96 in a state inclined forward and radially inward. It is formed in a plate shape. The lip portion 98b 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 98b, the inner periphery is slightly expanded and elastically engaged with the seal without elastically damaging the outer peripheral surface of the drive unit 68 of the other rotor 60. Thereby, the inside of the front part 88 is sealed.

  The rear portion 68a of the drive portion 68 in which the seal member 98 is slidably engaged with the periphery of the drive portion 68, that is, the outer peripheral surface is curved inward by external pressure to prevent the sealing effect from being lowered. The diameter is smaller than the front portion 68b of the portion 68 through the step portion 68c. The seal member 90 can be formed of an elastic material as long as it has a suitable sealing effect with the outer peripheral surface of the drive unit 68, but may be formed of a rubber material. preferable. In any case, the seal member 98 is disposed on the coupling wall 66 side of the radial opening 63 and is exposed to the outside through the radial opening 63 even when the spool 50 moves forward. Preferably not.

  In the fishing spinning reel 10, the spool 50 and the rotor 60 can be easily separated from the reel body 12, and necessary maintenance can be performed.

  First, the front part 88 of the reel body 12 is covered with the rear concave part 62a of the rotor body 62, and the driving part 68 protruding into the rear concave part 62a is provided on the operating part 22b of the hollow drive shaft 22 protruding from the front end of the front part 88. The lip portion 98b of the seal member 98 is seal-engaged with the outer periphery of the drive portion 68. This operation can be easily performed while visually observing from the outside by forming the radial opening 63 and the through hole 65 in the rotor body 62. Then, the tightening nut 102 is screwed into a threaded portion (not shown) formed at the tip of the operating portion 22b, and the tightening nut 102 is tightened to press the leading end surface of the spacer 90 with the rear end surface of the driving portion 68. The rotor 60 and the hollow drive shaft 22 are integrally coupled.

  After fixing the rotor 60 to the operating portion 22b of the hollow drive shaft 22, the mounting wall portion 78 of the front cylindrical portion 76 of the rotor body 62 is placed on the distal end surface of the connecting wall portion 66, and the inner peripheral surface of the insertion hole 78a. Engage with the corner of the tightening nut 102 and fix with the fixing screw 67. More than, for example, twice as many corners as the corners of the tightening nut 102 are formed on the inner peripheral surface of the insertion hole 78 a, the rotational position of the tightening nud 102 can be easily aligned with the fixing screw 67. be able to.

  Thereafter, the stopper 48a is mounted on the non-circular portion of the cross section of the spool shaft 26, and the spool 50 receives the front cylindrical portion 76 and the peripheral wall portion 64 of the rotor body 62 from the rear end side opening portion, and the rotor body 62 and the arm. The body portion 52 is inserted into the gap between the portion 70, 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. The assembly of the fishing spinning reel 10 is completed.

  According to the fishing spinning reel 10, the drive unit 68 disposed in the rear recess 62 a of the rotor body 62 is integrally connected to the hollow drive shaft 22 driven by the drive mechanism 24 in the reel body 12, A seal member 98 disposed between the periphery of the drive unit 68 and the front end portion of the front portion 88 that rotatably supports the hollow drive shaft 22 seals the inside of the front portion 88 of the reel body 12, thereby allowing foreign matter to be removed. Thus, the front portion 88 of the reel body 12 is reliably waterproofed and dust-proof. Thus, it is not necessary to provide a conventional flange portion for closing the rear opening end of the concave portion 62 of the rotor 60 in the reel body 12, and the front portion 88 of the reel body 12 is formed in a flangeless structure for fishing. The spinning reel can be made lighter and smaller.

  During the fishing operation, when the spool 50 moves back and forth with the spool shaft 26, the plurality of recesses 82 formed on the concave / convex outer peripheral portion C of the rotor body 62 allows air to freely flow inside and outside the spool 50. By entering and exiting, the occurrence of air resistance and abnormal noise due to air accumulation or retention in the spool 50 is prevented, and furthermore, the plurality of concave portions 82 and convex portions 84 form a fishing line locking function, This makes it possible to prevent the line from dropping from the direction, thereby effectively preventing the line from dropping off due to, for example, fluctuations in tension acting on the line, wind, and the like, so that a comfortable winding operation can be performed.

Further, the through-hole 65 formed in the connecting wall portion 66 of the rotor body 62 is aligned with the recess 82 in the axial direction, so that the air flow through the recess 82 is not obstructed, and the rear recess 62a or the radial opening is further prevented. Foreign matter such as water that has entered the peripheral wall portion 64 through the portion 63 can be discharged to the outside through the through-hole 65 and the concave portion 82, and the seal member 98 disposed in the peripheral wall portion 64 is corroded. In addition, it is possible to prevent the function from being deteriorated. Further, the radial opening 63 formed in the peripheral wall portion 64 of the rotor body 62 forms a suitable air permeability from the front portion to the rear portion of the rotor body 63, and allows moisture and air to flow. Prevent internal stagnation and make maintenance work such as washing after fishing easy and easy. For example, foreign matter such as seawater, sand, and dust that has entered the rear concave portion 62a can be washed with a shower or the like from the outside, and can be easily washed away through the radial openings 63 and 71 and the through holes 55 and 65. As a result, air permeability is improved, moisture and foreign matters are not retained in the interior, and corrosion can be induced and malfunction of the functional member can be prevented.

  Further, in addition to the flangeless structure of the front portion 88 of the reel body 12, the peripheral wall portion 64 of the rotor body 63 is enlarged in diameter on the rear opening end side, so that the front portion 88 of the reel body 12 is moved to the handle shaft 34. Even in the case where it is disposed in the rear recess 62 up to a position close to the outer periphery, the outer peripheral portion of the bearing cap 44 protruding from the side portion of the reel body 12 and attached to the lid body 12b does not interfere with the rotor 60. Therefore, the axial dimension 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.

  FIG. 5 shows an embodiment of a fishing spinning reel 10 </ b> A in which a front cylindrical portion 76 and a peripheral wall portion 64 are integrally formed. This fishing spinning reel 10A is different from the above-described embodiment only in that the entire rotor body 63 is formed in an integral structure. Therefore, the same reference numerals are used for the same main parts as in the above-described embodiment. The detailed description is omitted.

  In this embodiment, the rotor body 62 integrally forms the peripheral wall portion 64 and the front cylindrical portion 76, and is fastened and fixed to the operating portion 22 b of the drive shaft 22 by the tightening nut 102.

  Unlike the convex portion 84 formed in the shape of an arrow blade in the above-described embodiment, the convex portion 104 that forms the concave / convex outer peripheral portion C at the front portion of the rotor body 62 is formed in a rectangular plate shape. Between these adjacent convex portions 104, concave portions 84 that allow air to enter and exit and facilitate the discharge of foreign matters such as water are arranged substantially evenly along the circumferential direction.

  Also in the fishing spinning reel 10 </ b> A of this embodiment, the seal member 98 disposed between the periphery of the drive portion 68 of the rotor body 62 and the front portion 88 of the reel body 12 is provided with the front portion 88 of the reel body 12. By sealing the inside, there is no gap into which foreign matter enters the reel body 12, and the front portion 88 of the reel body 12 is reliably waterproofed and dust-proof. As a result, it is not necessary to provide a conventional flange portion on the reel body 12 for closing the rear opening end of the rear recess 62a of the rotor 60, and the front portion 88 of the reel body 12 is formed in a flangeless structure. This makes it possible to reduce the weight and size of spinning reels.

  Further, as in the above-described embodiment, the plurality of concave portions 82 formed in the concave / convex outer peripheral portion C of the rotor body 62 causes the air to flow inside and outside the spool 50 when the spool 50 and the spool shaft 26 move back and forth. By freely moving in and out, it is possible to prevent the occurrence of air resistance and abnormal noise due to air accumulation or retention in the spool 50, and the plurality of concave portions 82 and convex portions 104 form a fishing line locking function. Therefore, it is possible to prevent line dropping from all directions, thereby effectively preventing, for example, fluctuations in the tension acting on the fishing line and the line dropping of the fishing line due to the influence of wind, etc., and performing a comfortable winding operation. . The recess 82 and the through-hole 65 maintain suitable air permeability in the rear recess 62a of the rotor body 62, and there is no stagnation of moisture, foreign matter, and the like, thereby preventing corrosion and malfunction of the functional member. .

  Further, since the front cylindrical portion 76 is formed integrally with the peripheral wall portion 64, a mounting wall portion for fixing the front cylindrical portion 76 is unnecessary, and the weight can be further reduced.

  In addition, you may provide the member which latches a fishing line like the protrusion 86 in the above-mentioned embodiment, or a part also in the convex part 104 of embodiment of FIG.
