Description

The present invention relates to a spinning reel for fishing, which includes a rotatable rotor having a fishing thread guide portion and a spool that reciprocates back and forth.

The spinning reel for fishing includes a reel body that rotatably supports the handle, and this reel body has a built-in take-up drive mechanism for rotationally driving a rotor having a fishing thread guide portion. Further, the winding drive mechanism is provided with a reverse rotation prevention mechanism for preventing the rotor from rotating during casting or a fishing thread winding operation.

The take-up drive mechanism and the reverse rotation prevention mechanism are housed and supported in a storage recess formed in the reel body together with other reel components (see, for example, Patent Document 1 and Patent Document 2). As the reel body having such an accommodating recess, a reel body formed of a synthetic resin material is often used in order to reduce the weight and cost.

By the way, when the reel body is molded from resin using a mold, the molded product must be provided with a punching taper necessary for mold release. Further, in the case of resin molding, it is easily affected by the generation of dents due to heat shrinkage.

Shape defects caused by such punching tapers and dents in the reel body as a resin molded product may adversely affect the concentricity and positioning accuracy when the components are incorporated into the reel body. In particular, the portion of the accommodating recess of the reel body in which the take-up drive mechanism, the reverse rotation prevention mechanism, and the like are accommodated and supported is a portion that requires high concentricity and positioning accuracy. Machining is performed to eliminate shape defects including punching taper. However, such machining increases the number of manufacturing steps and manufacturing costs.

Moreover, although the resin is lightweight, its strength is lower than that of the metal. Therefore, during the high-load winding operation for winding the fishing thread under the condition that a high load is applied, the accommodation recess of the reel body that accommodates and supports the winding drive mechanism, the reverse rotation prevention mechanism, etc. is deformed, and the winding drive mechanism is affected by the deformation. And the function of the reverse rotation prevention mechanism may deteriorate. Therefore, in order to prevent such functional deterioration, it is necessary to increase the thickness of the reel body as a resin molded product, and the current situation is that effective weight reduction of the resin molded product has not been realized.

The present invention has been made by paying attention to the above-mentioned problems, and has a high degree of concentricity of reel components and a high degree of concentricity of reel components without performing machining to remove shape defects including a punching taper of the reel body as a resin molded product. It is an object of the present invention to provide a spinning reel for fishing that can secure positioning accuracy and can reinforce a resin reel body without thickening the reel body.

In order to achieve the above object, the spinning reel for fishing of the present invention is formed of a synthetic resin, and has a reel body in which an open accommodating recess in which a driving member is accommodating is formed, and the accommodating recess. The opening is closed, and the drive shaft portion arranged concentrically with the drive member has a through hole at the center, and is directly or indirectly attached to the inner peripheral surface of the opening of the accommodating recess. The reel is provided with a cover body having an annular mounting portion on the outer peripheral portion, and is fitted to the inner peripheral surface of the opening of the accommodating recess so that the cover body is concentrically positioned with respect to the reel body. It is characterized by having an annular functional member that reinforces the main body.

According to the spinning reel for fishing having the above configuration, the functional member is fitted to the inner peripheral surface of the opening of the accommodating recess, in other words, it functions to attach the cover body to the inner peripheral surface of the opening of the accommodating recess. By involving the members, the cover body is positioned concentrically with respect to the reel body, and as a result, the drive shaft portion penetrated through the through hole in the center of the cover body and concentric with the drive shaft portion. It is also possible to secure the concentricity of the drive member positioned with respect to the reel body. That is, the functional member has a shape defect due to a punching taper required at the time of mold release or a dent due to heat shrinkage in a portion of the accommodating recess of the reel body that requires high concentricity and positioning accuracy. Also, it eliminates the need for machining to eliminate these defects, and ensures high concentricity and positioning accuracy of the drive member, the drive shaft, and the reel components involved therein. Therefore, it is possible to avoid an increase in the number of manufacturing processes and manufacturing costs due to machining. In particular, if the cover body that closes the accommodating recess cannot be positioned with accurate concentricity, it may come into contact with the driving member in the accommodating recess and hinder the driving of the driving member and the rotation of the drive shaft portion. To obtain, the presence of functional members is beneficial.

Further, since the functional member is fitted to the inner peripheral surface of the opening of the accommodating recess to reinforce the reel body, it is made of resin even during a high load winding operation in which the fishing thread is wound under a high load. It is possible to effectively suppress the deformation of the accommodating recess of the reel body. Therefore, it is not necessary to reinforce the resin reel body by increasing the wall thickness. Therefore, it is possible to stabilize the performance of the drive mechanism including the drive member and the drive shaft portion while fully utilizing the advantages (light weight and low cost) of the resin reel body.

In the above configuration, the cover body can be formed of various materials such as a metal such as aluminum, a resin, a magnetic material, and a non-magnetic material. Further, examples of the drive member include a one-way clutch that regulates the rotation of the drive shaft portion in one direction, a rolling bearing that supports the rotation of the drive shaft portion with high accuracy, and the like. Further, examples of the drive shaft portion include a spool shaft and a pinion gear.

Further, in the above configuration, the functional member is press-fitted into the inner peripheral surface of the opening of the accommodating recess to correct the shape of the accommodating recess, so that the cover body fitted to the inner peripheral surface of the opening of the accommodating recess is formed. It may be positioned concentrically with respect to the reel body. According to this, for example, a punching taper required for mold release is formed in the opening of the accommodating recess, and the concentricity between the cover body, the drive member, and the drive shaft portion when the cover body is attached to the opening of the accommodating recess. Even when the accommodating recess has a shape that cannot be removed, the functional member has a cover body fitted to the inner peripheral surface of the opening of the accommodating recess with respect to the reel body (thus, on the drive member and the drive shaft portion). On the other hand, the shape of the accommodating recess can be corrected by press-fitting into the inner peripheral surface of the opening of the accommodating recess so as to be positioned concentrically. In this case, it is preferable that the correction of the shape of the accommodating recess by the functional member not only secures the concentricity of the cover body with respect to the reel body, but also secures the concentricity of the entire reel component incorporated in the accommodating recess with respect to the reel body.

Further, in the above configuration, the functional member has a shape in which the outer peripheral surface of the functional member fitted to the inner peripheral surface of the opening of the accommodating recess follows the shape of the inner peripheral surface of the opening, and the cover body is concentric with the reel body. A positioning surface for positioning is provided on the inner circumference thereof, and a cover body may be fitted to this positioning surface. According to this, the functional members are arranged along the shape of the accommodating recess without correcting the shape of the accommodating recess, and are concentric with respect to the reel body of the cover body fitted to the positioning surface by the positioning surface. The degree can be secured. In other words, in the functional member, for example, a punching taper required at the time of mold release is formed in the opening of the accommodating recess, and when the cover body is attached to the opening of the accommodating recess, the cover body is between the drive member and the drive shaft portion. Even if the accommodating recess has a shape that cannot be concentric, the positioning surface thereof is interposed between the cover body and the accommodating recess so that the cover body is not affected by the shape of the accommodating recess. This makes it possible to secure the concentricity of the cover body with respect to the reel body. Further, according to such a configuration, a mold for forming the accommodating recess is formed on the outer peripheral surface of the functional member fitted to the inner peripheral surface of the opening of the accommodating recess (for example, a die is formed on the inner peripheral surface of the accommodating recess. There is also an advantage that it can be formed with the same mold as the mold to be used.

Further, in the above configuration, the functional member may regulate the movement of the cover body in the axial direction. According to this, the functional member can maintain the positioning state in the axial direction while positioning the cover body concentrically with respect to the reel body in the radial direction.

Further, in the above configuration, the reel body may have ribs in the accommodating recesses that reinforce the reel body and regulate the axial movement of the functional member. According to this, since the axial movement of the functional member is regulated by the rib, it is possible to avoid the inconvenience that the cover body deviates from the concentric positioning state as the functional member moves. The axial movement of the functional member may be regulated by a configuration other than the rib. For example, the movement of the functional member in the axial direction may be restricted by engaging the functional member with a portion of the reel body that forms an opening of the accommodating recess.

Further, in the above configuration, a seal portion for sealing the gap between the cover body and the drive shaft portion may be further provided. Examples of such a sealing portion include a magnetic seal and a rubber seal. When the seal portion is a magnetic seal, the cover body may also serve as the electrode plate of the magnetic seal.

Further, in the above configuration, the accommodating recess may be provided in the reel body in various forms. For example, the accommodating recess may be formed in the front portion of the reel body, and in that case, a reel component including a rotation control device for controlling the rotation direction of the drive shaft portion and a bearing may be accommodated in the accommodating recess. Alternatively, the accommodating recess may be formed on the side portion of the reel body, and in that case, a winding drive mechanism for rotationally driving the rotor having the fishing thread guide portion may be accommodated in the accommodating recess.

According to the present invention, it is possible to secure high concentricity and positioning accuracy of reel components without performing machining to remove shape defects including a punching taper of the reel body as a resin molded product, and a resin reel. A spinning reel for fishing that can be reinforced without thickening the main body can be obtained.

It is a side view which includes a partial cross section of the spinning reel for fishing which concerns on 1st Embodiment of this invention. It is an enlarged sectional view of the main part of FIG. It is sectional drawing corresponding to FIG. 2 of the spinning reel for fishing which concerns on 2nd Embodiment of this invention. It is sectional drawing corresponding to FIG. 2 of the spinning reel for fishing which concerns on 3rd Embodiment of this invention. It is a partially enlarged sectional view of the part A of FIG. It is a schematic plan view of the accommodating recess of a reel body with a reinforcing rib which supports a functional member in an axial direction.

Hereinafter, embodiments of the spinning reel for fishing according to the present invention will be described with reference to the drawings.
1 and 2 are views showing a first embodiment of a spinning reel for fishing according to the present invention, FIG. 1 is a view showing an internal configuration, and FIG. 2 is a view near a housing recess of a reel body. It is an enlarged sectional view of a main part.

A handle shaft 2 is rotatably supported on a reel body 1 of a spinning reel formed of synthetic resin via a bearing (not shown), and a winding operation is performed on the end of the handle shaft 2. The handle 3 is attached. A drive gear (drive gear) 4 is attached to the handle shaft 2 so as to be integrally rotatable, and the drive gear 4 extends in a direction orthogonal to the handle shaft 2 and has bearings 5a and 5b. The tooth portions 7a of the pinion gear (drive shaft portion) 7 rotatably supported via the mesh are meshed with each other. A rotor 9 provided with a bale 9a and a fishing thread guide device 9b is attached to the tip of the pinion gear 7 so as to rotate integrally by screwing a rotor nut 8.

The pinion gear 7 penetrates along the axial direction, and a spool shaft (drive shaft portion) 11 holding a spool 10 around which a fishing thread is wound is inserted therein. A known oscillating mechanism 13 is connected to the base end side of the spool shaft 11, and when the handle shaft 2 is rotated by the rotation operation of the handle 3, the spool shaft 11 is reciprocated along the axial direction. To. In this case, a bearing 14 is interposed between the spool shaft 11 and the rotor nut 8 so as to rotatably support the rotor nut 8 that fixes the rotor 9 to the pinion gear 7. Specifically, the spool shaft 11 is inserted through a collar member 15 installed at the tip edge of the pinion gear 7, and the bearing 14 is interposed between the collar member 15 and the rotor nut 8.

Further, a one-way clutch (rotation control device for controlling the rotation direction of the pinion gear 7) 20 as a driving member is provided in the middle portion of the pinion gear 7, and the one-way clutch 20 is the pinion gear 7. It is interposed between the reel body 1 and the pinion gear 7 to regulate and control the rotation direction of the pinion gear 7 as is known. The one-way clutch 20 constitutes a known reverse rotation prevention mechanism that prevents reverse rotation of the handle 3 (rotor 9) in the fishing thread feeding direction.

The one-way clutch 20 includes an inner ring 21 that is anti-rotated to the pinion gear 7, a cage 22 that is arranged outside the inner ring 21, an outer ring 23 that is arranged outside the cage 22, and an outer ring 23. It is provided with a plurality of rolling members (rollers) 25 rotatably held by a cage 22 inside the cage, and is in a state of being sealed by a magnetic seal mechanism 30 installed adjacent to the roll member (roller) 25.

A free rotation region that allows each rolling member 25 to freely rotate and a wedge region that prevents the rotation thereof are formed on the inner peripheral surface of the outer ring 23, and each rolling member 25 is provided on the cage 22. It is urged toward the wedge region by a spring member (not shown). Further, the outer ring 23 is fixed to the reel body 1 in a non-rotating manner by engaging with unevenness as is known.

In the one-way clutch 20 having the above configuration, when the inner ring 21 rotates forward (the rotor 9 rotates in the fishing thread winding direction) together with the pinion gear 7, the rolling member 25 of the cage 22 is positioned in the free rotation region of the outer ring 23. Therefore, the rotational force of the inner ring 21 is not transmitted to the outer ring 23 (not blocked by the outer ring 23), and therefore the rotor 9 rotates together with the pinion gear 7 without any trouble. On the other hand, when the inner ring 21 tries to rotate in the reverse direction (the rotor 9 rotates in the fishing thread feeding direction) together with the pinion gear 7, the rolling member 25 of the cage 22 is located in the wedge region of the outer ring 23, and this serves as a stopper. The rotation (reverse rotation) of the pinion gear 7 and the rotor 9 is prevented.

Next, the magnetic seal mechanism 30 arranged in the spinning reel having the above configuration will be described. The magnetic seal mechanism 30 of the present embodiment is configured to seal the one-way clutch 20 and the like as a member to be sealed.
The one-way clutch 20 is housed together with other reel components including a bearing 5a in a housing recess 1Aa inside a tubular portion 1A formed in the front portion of the reel body 1. The inner ring 21 of the one-way clutch 20 is made of a magnetic material and rotates integrally with the pinion gear 7. In this case, the inner ring 21 is formed with a cylindrical protruding portion 21a that protrudes toward the spool side from the front end surfaces of the cage 22 and the outer ring 23, and the magnetic seal mechanism 30 is arranged in this portion. It is configured in. That is, the protruding portion 21a is integrally formed on the inner ring 21 which is a constituent member of the one-way clutch 20, and has a function of holding the magnetic fluid constituting the magnetic sealing mechanism 30. Therefore, the pinion gear 7 can be made of a non-magnetic material (for example, copper alloy, aluminum alloy, etc.).

The magnetic seal mechanism 30 includes a magnet 31 arranged at a predetermined distance from the protruding portion 21a, a pair of electrode plates (holding members) 32 and 33 that sandwich and hold the magnet 31, a magnet 31, and an electrode plate. It includes 32, 33, and a magnetic fluid 35 held in a magnetic circuit formed by the protrusion 21a. In this case, the magnet 31 and the electrode plates 32, 33 are formed in a ring shape so as to have a predetermined gap from the outer peripheral surface of the projecting portion 21a, and the gap between each electrode plate 32, 33 and the projecting portion 21a. In addition, it is possible to hold the magnetic fluid 35 over the entire circumference. That is, the magnetic fluid 35 is formed by dispersing magnetic fine particles such as Fe ₃ O _{4 in} a base oil with a surfactant, and has a viscous property of reacting when a magnet is brought close to it. .. Therefore, the magnetic fluid 35 is formed by a magnetic circuit formed by a ring-shaped magnet 31, plates 32 and 33 that sandwich and hold the magnets, and a protrusion 21a made of a magnetic material, thereby forming the respective plates 32 and 33. It is stably held over the entire circumference in the gap between the protrusion 21a and the protrusion 21a, and seals the one-way clutch 20.

By the way, such a magnetic seal mechanism 30 seals the inside of the accommodating recess 1Aa of the reel body 1 in which the one-way clutch 20 and the like are accommodating to the outside, and also serves as the electrode plate 33 of the magnetic seal mechanism 30. A seal portion that seals the gap between the cover body 33 that closes the opening 1Ab of the accommodating recess 1Aa and the pinion shaft 7 (inner ring 21 in the present embodiment) is configured.

The cover body 33 (the electrode plate of the magnetic seal 30) that closes the opening 1Ab of the accommodating recess 1Aa has a through hole 33a through which the pinion gear 7 arranged concentrically with the one-way clutch 20 penetrates, and also has the accommodating recess. The outer peripheral portion has an annular mounting portion 33b that is directly attached to the inner peripheral surface 1Ae of the opening 1Ab of 1Aa.

Further, in the present embodiment, a punching taper required for pulling out the resin-molded reel body 1 from the mold at the time of mold release is formed on the inner peripheral surface 1Ae of the opening 1Ab of the housing recess 1Aa, and is accordingly accommodated. When the cover body 33 is attached to the opening 1Ab of the recess 1Aa, the housing recess 1Aa has a shape in which concentricity cannot be easily obtained between the cover body 33, the one-way clutch 20, and the pinion gear 7. Therefore, in the present embodiment, an annular function is fitted to the inner peripheral surface 1Ae of the opening 1Ab of the accommodating recess 1Aa so that the cover body 33 is concentrically positioned with respect to the reel body 1 to reinforce the reel body 1. A member 60 is provided.

In particular, the functional member 60 in the present embodiment is press-fitted into the opening end side of the inner peripheral surface 1Ae of the opening 1Ab of the accommodating recess 1Aa to correct the shape of the opening end side of the accommodating recess 1Aa into a perfect circle. By correcting the dent deformation, etc.), the cover body 33 fitted to the inner peripheral surface 1Ae of the opening 1Ab of the accommodating recess 1Aa can be easily incorporated into the reel body 1, and the cover body 33 is concentric with the reel body 1. It is designed to be positioned.

Further, the functional member 60 having such a concentric positioning function and a reinforcing function is supported on the lower surface 60b by the upper surface 1Ada of a plurality of ribs 1Ad protruding inward in the radial direction from the inner peripheral surface 1Ae of the accommodating recess 1Aa. Axial movement is regulated. Further, these ribs 1Ads supporting the functional member 60 also serve as reinforcement of the reel main body 1, and are arranged in pairs, for example, at an angular interval of 120 degrees in the circumferential direction as shown in FIG. Has been done.

In the cover body 33 concentrically positioned by such a functional member 60, the peripheral edge of the mounting portion 33b on the outer periphery thereof is formed on the opening end side of the inner peripheral surface 1Ae of the tubular portion 1A of the reel body 1. It is locked to the annular step portion 1Ac and is supported by a cap 50 screwed to the tubular portion 1A to prevent it from coming off from the outside of the accommodating recess 1Aa. Further, in the present embodiment, the cover body 33 is supported by the upper surface 60a of the functional member 60 to regulate its movement in the axial direction, but the cover body 33 is sufficiently shafted by being locked with the annular step portion 1Ac. Since the directional movement is restricted, it does not have to be supported by the upper surface 60a of the functional member 60.

The functional member 60 of the present embodiment has an inclined surface 60c on the outer peripheral portion, which is fitted to the inner peripheral surface 1Ae of the opening 1Ab of the reel body 1 and extends obliquely from the fitting surface toward the upper surface 60a. A lightening step portion 60d is provided on the inner peripheral portion. An O-ring 90 may be interposed between the inclined surface 60c and the inner peripheral surface 1Aa to prevent water from entering the inside.

When such a functional member 60 is press-fitted into the inner peripheral surface 1Ae of the opening 1Ab of the housing recess 1Aa, the opening shape of the housing recess 1Aa is corrected to a perfect circle, and the cover body 33 is concentric with the reel body 1. Therefore, the concentricity of the pinion gear 7 and the one-way clutch 20 positioned concentrically with the pinion gear 7 penetrating the through hole 33a at the center of the cover body 33 with respect to the reel body 1 is also maintained and secured. ..

As described above, according to the present embodiment, the functional member 60 is fitted to the inner peripheral surface 1Ae of the opening 1Ab of the accommodating recess 1Aa, in other words, the inner peripheral surface 1Ae of the opening 1Ab of the accommodating recess 1Aa. By involving the functional member 60 in the attachment of the cover body 33 to the reel body 1, the cover body 33 is concentrically positioned with respect to the reel body 1, and as a result, the center of the cover body 33 is centered. It is also possible to secure the concentricity of the pinion gear 7 penetrated through the through hole 33a and the one-way clutch 20 positioned concentrically with the pinion gear 7 with respect to the reel body 1. That is, when the functional member 60 has a shape defect due to a punching taper required at the time of mold removal or a dent due to heat shrinkage in the portion of the accommodating recess 1Aa of the reel body 1 that requires high concentricity and positioning accuracy. Even so, high concentricity and positioning accuracy of the one-way clutch 20, the pinion gear 7, and the reel components involved in them are ensured by eliminating the need for machining to eliminate these defects. Therefore, it is possible to avoid an increase in the number of manufacturing processes and manufacturing costs due to machining. In particular, if the cover body 33 that closes the accommodating recess 1Aa cannot be positioned with accurate concentricity, it comes into contact with the one-way clutch 20 in the accommodating recess 1Aa to drive the one-way clutch 20 or rotate the pinion gear 7. The presence of the functional member 60 is beneficial because it can cause problems.

Further, since the functional member 60 is fitted to the inner peripheral surface 1Ae of the opening 1Ab of the accommodating recess 1Aa to reinforce the reel body 1, it is necessary to wind the fishing thread under a high load winding operation. Even if there is, the deformation of the accommodating recess 1Aa of the resin reel body 1 can be effectively suppressed. Therefore, it is not necessary to reinforce the resin reel body 1 by increasing the wall thickness. Therefore, it is possible to stabilize the performance of the drive mechanism including the one-way clutch 20 and the pinion gear 7 while fully utilizing the advantages (light weight and low cost) of the resin reel body 1.

Further, in the present embodiment, the functional member 60 is press-fitted into the inner peripheral surface 1Ae of the opening 1Ab of the accommodating recess 1Aa to correct the shape of the accommodating recess 1Aa, whereby the inner peripheral surface of the opening 1Ab of the accommodating recess 1Aa is corrected. The cover body 33 fitted to the 1Ae is positioned concentrically with respect to the reel body 1. Therefore, as in the present embodiment, the punching taper required at the time of mold release is formed in the opening 1Ab of the accommodating recess 1Aa, so that the cover body 33 and the one-way clutch 20 are attached to the opening 1Ab of the accommodating recess 1Aa. Even when the accommodating recess 1Aa forms a shape that cannot be concentric with the pinion gear 7, the functional member 60 is fitted to the inner peripheral surface 1Ae of the opening 1Ab of the accommodating recess 1Aa. Is press-fitted into the inner peripheral surface 1Ae of the opening 1Ab of the accommodating recess 1Aa so as to be concentrically positioned with respect to the reel body 1 (hence, with respect to the one-way clutch 20 and the pinion gear 7). The shape of the can be corrected.

FIG. 3 shows a cross-sectional view corresponding to FIG. 2 of the spinning reel for fishing according to the second embodiment of the present invention. As shown in the figure, in the present embodiment, the seal portion that seals the inside of the accommodating recess 1Aa to the outside is interposed between the cover body 33 and the inner ring 21 instead of the magnetic seal 30 as in the first embodiment. It is formed by a rubber seal 49. Therefore, the cover body 33 does not form the electrode plate of the magnetic seal 30, and functions as a mere closing body.

Further, the functional member 60A of the present embodiment does not have the stepped portion 60d as in the first embodiment and has a compact form in which the upper surface 60a is short. However, the functional member 60A is also the first. Similar to that of the embodiment, it is press-fitted into the inner peripheral surface 1Ae of the opening 1Ab of the accommodating recess 1Aa to correct the shape of the accommodating recess 1Aa so that it is fitted to the inner peripheral surface 1Ae of the opening 1Ab of the accommodating recess 1Aa. The cover body 33 is positioned concentrically with respect to the reel body 1. However, in the present embodiment, unlike the first embodiment, the cover body 33 is not locked to the annular step portion 1Ac of the tubular portion 1A, so that the functional member 60 supports the cover body 33 by its upper surface 60a. The axial movement of the cover body 33 is regulated. The other configurations are the same as those of the first embodiment, and therefore, the same effects as those of the first embodiment can be obtained.

FIG. 4 shows a cross-sectional view corresponding to FIG. 2 of the spinning reel for fishing according to the third embodiment of the present invention. As shown in the figure, in the present embodiment, the concentric positioning form of the cover body by the functional member is different from the first and second embodiments described above. That is, the functional member 70 of the present embodiment has a shape in which the outer peripheral surface 70c fitted to the inner peripheral surface 1Ae of the opening 1Ab of the accommodating recess 1Aa follows the shape of the inner peripheral surface 1Ae of the opening 1Ab with a pull-out taper. As shown clearly enlarged in FIG. 5, the shape extends diagonally outward in the radial direction, and the positioning surface 70a for concentrically positioning the cover body 33 with respect to the reel body 1 is included therein. A mounting portion 33b of the cover body 33 is fitted on the positioning surface 70a. That is, the cover body 33 is indirectly attached to the inner peripheral surface 1Ae of the opening 1Ab of the accommodating recess 1Aa via the functional member 70. In this case, the positioning surface 70a is a stepped surface formed by a plane (bottom surface) 70a1 orthogonal to the axial center axis of the reel body 1 and a plane (inner peripheral surface) 70a2 parallel to the axial center axis of the reel body 1. The cover body 33 is positioned concentrically with the reel body 1 in the axial direction and the radial direction. Further, the functional member 70 is supported by the rib 1Ad on the lower surface 70b of the functional member 70, and its movement in the axial direction is restricted, as in the above-described embodiment. The other configurations are the same as those in the second embodiment.

According to the present embodiment of such a form, the functional member 70 functions as a straightening member that concentrically attaches the cover body 33 to the reel body 1 by canceling the punching taper formed on the inner peripheral surface 1Aa. , The shape of the accommodating recess 1Aa is not corrected as in the first and second embodiments, and the accommodating recess 1Aa is fitted to the positioning surface 70a by the positioning surface 70a while being arranged along the shape of the accommodating recess 1Aa. The concentricity of the cover body 33 with respect to the reel body 1 can be ensured. In other words, the functional member 70 has a cover body 33 when the cover body 33 is attached to the opening 1Ab of the housing recess 1Aa by forming a punching taper required at the time of mold release in the opening 1Ab of the housing recess 1Aa as in the present embodiment. Even if the accommodating recess 1Aa forms a shape in which concentricity cannot be obtained between the 33 and the one-way clutch 20 and the pinion gear 7, the cover body 33 is not affected by the shape of the accommodating recess 1Aa. The concentricity of the cover body 33 with respect to the reel body 1 can be ensured by the positioning surface 70a while interposing between the cover body 33 and the accommodating recess 1Aa. Further, according to such a configuration, a mold (inner peripheral surface of the accommodating recess 1Aa) for forming the accommodating recess 1Aa on the outer peripheral surface 70c of the functional member 70 fitted to the inner peripheral surface 1Ae of the opening 1Ab of the accommodating recess 1Aa. There is also an advantage that it can be formed with the same mold as (a mold for forming a punching taper in 1Ae).

Needless to say, the present invention is not limited to the above-described embodiment, and can be modified in various ways without departing from the gist thereof. For example, in the above-described embodiment, the accommodating recess is formed in the front portion of the reel body, but accommodates a take-up drive mechanism formed in the side portion of the reel body to rotationally drive the rotor having the fishing thread guide portion. It doesn't matter. Further, in the above-described embodiment, the driving member housed in the housing recess is a one-way clutch, but the driving member housed in the housing recess is not limited to the one-way clutch.
