Description

The present invention relates to fishing spinning reels, and more particularly to fishing spinning reels having features in the rotor portion.

A spinning reel for fishing has a structure including a rotor that rotates in conjunction with a winding and rotating operation of a handle and a spool that moves back and forth. A pair of support arms (arm portions) rotating around the spool are integrally formed on the rotor radially outwardly of the cylindrical portion so as to protrude forward. A bail supporting member (arm lever) is rotatably supported at the tip of each of the fishing line winding positions and the fishing line releasing positions. Also, one of the bail support members is provided with a fishing line guide device for guiding the fishing line picked up by the bail to the line winding body of the spool when the bail support member is rotated from the fishing line releasing position to the fishing line winding position. It is

The fishing line is evenly wound around the fishing line winding body of the spool as the fishing line guide device rotates around the spool together with the rotor while the spool moves back and forth. In such a spinning reel for fishing, there is a problem that the fishing line wound around the spool becomes entangled in the rotor due to the influence of looseness of the fishing line, tangling of the line, the posture of the reel body, etc., when the fishing line is released or wound. occurs. Further, in some cases, the thread may enter between the skirt portion of the spool and the cylindrical portion of the rotor, and may become entangled with the spool shaft (thread dropping phenomenon).
Therefore, for example, Patent Document 1 discloses a configuration in which a cover member is attached to the front wall of the cylindrical portion of the rotor. A protruding portion that protrudes radially outward is formed on the outer peripheral portion of the cover member to prevent the fishing line from falling forward along the outer peripheral surface of the cylindrical portion.

Patent No. 5401411

In the above-described rotor, a disk-shaped wall for attaching a cover member is formed on the front side of the cylindrical portion, and the entire circumference is thickened, so that sufficient weight reduction cannot be achieved. In other words, there is room for improvement in terms of preventing thread dropout while reducing the weight of the rotor.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a spinning reel for fishing that reduces the weight of the rotor and prevents the line from dropping.

In order to achieve the above object, the present invention provides a rotor that rotates together with a drive shaft when a handle rotatably supported on a reel body is rotated, and a pair of rotors that are provided on the rotor and protrude forward. a pair of bail support members disposed at the ends of each of the pair of support arms and divided and held at a fishing line winding position and a fishing line releasing position; and attached to one of the pair of bail support members. and a fishing line guide device, wherein the rotor has a cylindrical portion with an opening extending from a front wall to a cylindrical wall, and the front wall is formed on the cylindrical wall. It is characterized by comprising a cover member that is provided with a locking portion that protrudes radially outward from the outer periphery and that is attached so as to close the opening.

In the rotor of the spinning reel for fishing with the above-described configuration, the opening is formed in the cylindrical portion from the front wall to the cylindrical wall, so that the weight of the cylindrical portion can be reduced. By attaching a cover member having a locking portion projecting radially outward so as to close the opening, it is possible to prevent the thread from dropping.

According to the present invention, it is possible to obtain a spinning reel for fishing that prevents line dropping while reducing the weight of the rotor.

An embodiment of a spinning reel for fishing according to the present invention will be specifically described below with reference to the drawings.
1 to 3 are diagrams showing one configuration example of a fishing spinning reel according to one embodiment of the present invention. First, an overview of the overall configuration of the spinning reel for fishing will be described. In the following description, front and rear of the rotor mean the directions shown in FIGS. 1 and 2. FIG.

A reel body 2 of a spinning reel 1 for fishing is formed with a leg portion 2A to be attached to a fishing rod. A handle shaft is rotatably supported in the reel body via a bearing, and a handle 3 for winding operation is attached to the end of the handle shaft. Further, a known driving force transmission mechanism is connected to the handle shaft, and rotates the rotor 10 as the handle 3 is rotated, and moves the spool 5 back and forth via a known oscillating mechanism. It's like

The spool 5 is made of, for example, a metal having a low specific gravity such as aluminum, an aluminum alloy, or a magnesium alloy, or a synthetic resin material. It has a front flange portion 5b and a rear flange portion (skirt portion) 5c that define the amount of line wound on the trunk portion 5a in the front-rear direction.

A pair of support arms 11 and 12 are formed on the rotor 10 so as to extend axially forward and face each other at an interval of approximately 180°, and the spool 5 is positioned between the pair of support arms. It is driven to reciprocate back and forth. Rotational support portions 14a and 15a of bail support members 14 and 15 are rotatably supported between the fishing line winding position and the fishing line releasing position at the distal end portions 11A and 12A of the support arms 11 and 12, respectively. (See Figure 4). A base end portion of a semi-annular bail 17 is attached to each of the bail support members 14 and 15 , and the bail 17 can rotate together with the bail support members 14 and 15 . A fishing line guide device 50 for guiding the fishing line to the spool is disposed at the tip of one of the bail support members 15 (see FIG. 2).

As is well known, the fishing line guiding device 50 includes a fishing line guiding portion (line roller) 51 for guiding the fishing line to the spool 5 and a fishing line guiding portion (line slider) 53 for guiding the fishing line from the bail 17 to the line roller 51. One base end portion 17 a of the bail 17 is coupled to the fishing line guide portion 53 . The bail 17 is formed in a hollow shape and is integrally connected to the mounting portion 53a of the fishing line guiding portion 53. The bail 17 has a solid structure and is integrally connected to the mounting portion 53a of the fishing line guiding portion 53. Alternatively, it may extend from the mounting portion 53a of the fishing line guiding portion 53 and be formed integrally with the fishing line guiding portion 53. As shown in FIG. Further, it is preferable that the mounting portion 53a of the fishing line guiding portion 53 and the base end portion 17a of the bail 17 are joined flush with each other without a step.

1 to 3 show the fishing line winding state. When the handle 3 is rotated in this state, the rotor 10 is driven to rotate via the driving force transmission mechanism, and the spool 5 moves forward and backward via the oscillating mechanism. driven to and fro. As a result, the fishing line is evenly wound around the fishing line winding body 5a of the spool 5 through the line roller 51 of the fishing line guide device 50 of the bail support member 15 that rotates together with the rotor 10. As shown in FIG.

When the bail 17 is rotated (rotated in the direction of the arrow) from the fishing line winding state shown in the figure to the fishing line releasing position along with the rotation of the bail supporting members 14 and 15, the fishing line wound around the spool 5 is A release state (not shown) is reached. After the fishing line is released in this fishing line releasing state, the bail 17 is rotated from the fishing line releasing position to the fishing line winding position. and the fishing line is reeled in as shown in the figure.

In the above-described configuration, when the fishing line is wound with the fish hooked, a large tensile force acts on the fishing line. A large load acts on the support arm 12 . Since this load acts particularly on the side portion of the support arm 12 opposite to the bale side where the fishing line guide device 50 is provided, the rigidity balance of the whole will deteriorate unless the strength of this portion is improved. In this embodiment, a reinforcing portion as described later is provided so as to increase the rigidity of this portion without increasing the weight.

The bail 17 is rotated between a fishing line releasing position and a fishing line winding position, and is distributed and held at one of the positions. In this case, the rotation (reversal return) from the fishing line releasing position to the fishing line winding position is performed manually by gripping the bail 17, or via a reversing mechanism when the handle 3 is operated to wind. It is possible. Since this reversing mechanism is well known, its configuration will be omitted, but it can be incorporated inside one of the support arms 11 and 12. In this embodiment, the support arm on the side where the fishing line guide device 50 is mounted 12 is incorporated. For this reason, a recess 12B' for accommodating the reversing mechanism is formed on the outside of the support arm 12, and the opening of the recess 12B' is closed by a cover member 12B attached to the support arm 12. (see FIG. 9).

A line roller 51 of the fishing line guide device 50 is formed in a cylindrical shape and is rotatably supported between the bail support member 15 and the fishing line guide portion 53 . In the line roller 51 of this embodiment, a known bearing (not shown) is interposed in the shaft portion of the attachment member (screw member in this embodiment) 55 that fixes the fishing line guide portion 53 to the bail support member 15. is rotatably supported by

The fishing line guiding portion 53 is integrally formed of a lightweight metal material with good slidability, such as a thin film of stainless steel alloy or aluminum alloy, and has an opening 53b that opens in a substantially circular shape on the bail support member 15 side. The mounting portion 53a coupled to the base end portion 17a of the bail 17 is provided on the opposite side of the opening 53b.

Further, the fishing line guide portion 53 is formed with a concave portion 53A that accommodates the head portion 55a of the attachment member 55 without protruding outward. The concave portion 53A is formed between a pair of inclined portions 53d that gradually widen and rise along the axial direction from the mounting portion 53a toward the bail support member. The upper end sides of the pair of inclined portions 53d on both sides of the recessed portion 53A are integrated with a ring-shaped annular portion 53e, and the opening 53b is formed on the side of the bail support member. The lower end side is integrated with the mounting portion 53a.

In the above-described configuration, the attachment member 55 is inserted from the bail 17 side (in the direction of the arrow D1 in FIG. 4), and the line roller 51 is rotatably supported through bearings in the intermediate portion of the shaft portion of the attachment member. there is Furthermore, the male threaded portion formed at the end of the shaft portion is screwed into and fixed to the female threaded portion provided on the inner surface of the bail support member 15, and the fishing line guiding portion 53 is fixed to the bail support member 15. . Therefore, as shown in FIGS. 2 and 3, the attachment member 55 that attaches the fishing line guide portion 53 to the bail support member 15 faces the bail 17 side and is exposed from the outer surface of the bail support member 15. Therefore, it is possible to suppress entanglement of the fishing line by forming the outer surface into a smooth surface.

Next, the basic structure of the rotor 10 will be described in detail with reference to FIGS. 4 to 11 in addition to FIGS. 1 to 3. FIG.
The main body 10A of the rotor 10 is integrally formed of a lightweight and high-strength material such as aluminum alloy, magnesium alloy, or hard resin. The main body 10A is integrally formed with the pair of support arms 11 and 12 at an interval of approximately 180° so as to protrude forward along the spool shaft. A tubular portion 20 is formed in the .

A cylindrical wall 21 of the cylindrical portion 20 is closed on the front side by a front wall 22 and has a substantially circular opening on the rear end. In this case, the rear end is integrated with a ring-shaped connecting portion 25, which will be described later, and an inner edge 25' of the ring-shaped connecting portion 25 serves as an opening of the cylindrical wall 21 (cylindrical portion 20). Further, the cylinder wall 21 is formed in a substantially cylindrical shape, and an opening is formed in the cylinder wall 21 so as to reduce the weight. The opening of this embodiment is formed in an arc shape along the circumferential direction from the upper side of the cylindrical wall 21 to the rear edge of the cylindrical wall 21, and faces the pair of support arms 11 and 12. Openings 21d and 21e having substantially the same shape are formed in regions other than the arc walls 21a and 21b within a certain range (see FIGS. 4 to 7). The lower ends of the arc walls 21a and 21b are connected to the lower ends of the support arms 11 and 12 via the connecting portion 23, and the surface of each arc wall is connected to the support arm extending forward. They face each other at a constant interval.

In this way, the openings 21d and 21e are formed large without the rear end edge of the cylinder wall 21, so that the area where the openings 21d and 21e are formed becomes a space. A ring-shaped connecting portion 25 is provided in substantially the same plane as the rear edge of the wall 21 so as to protrude in the radial direction. The ring-shaped connecting portion 25 is formed along the openings 21d and 21e to constitute the rear end portion of the rotor (the rear end portion of the cylindrical wall 21), and also the base portions of the support arms 11 and 12 on both sides thereof. It connects the parts. That is, the ring-shaped connecting portion 25 is connected to the rear ends of the support arms 11 and 12 and is integrated with the support arms 11 and 12, preferably integrally formed of the same material.
The ring-shaped connecting portion 25 of this embodiment is formed so that its outer peripheral surface is along the surfaces of the arc walls 21a and 21b, and between the support arms 11 and 12, the ring-shaped connecting portion extends radially outward. A curved wall 25a is integrally formed along 25. As shown in FIG. The curved wall 25a is integrated with reinforcing portions 26a to 26d, which will be described later, and is flush with the surfaces of the reinforcing portions. It has a curved surface.

By forming the openings 21d and 21e as described above in the cylindrical wall 21, both sides of the circular arc walls 21a and 21b are opened widely. The front wall 22 of the tubular wall 21 of the tubular portion 20 has a flat bridge 20A that radially connects the opening front edge of the tubular wall 21 with a predetermined width (FIG. 6A). reference). In this case, both sides of the bridge 20A may be formed into a wide space by the openings 21d and 21e up to the ring-shaped connecting portion 25, but in this embodiment, the upper ends of the arc walls 21a and 21b are connected by semi-annular frames 21f and 21g. That is, as shown in FIGS. 5 and 6(a), the bridge 20A is in a state of being bridged over the cylindrical wall 21 of the cylindrical portion 20 between the support arms 11 and 12, and both sides thereof are , and the semi-annular frames 21f and 21g. For this reason, in the present embodiment, the openings 21d and 21e are formed with front side openings 21d1 and 21e1 on the front wall side with the semi-annular frames 21f and 21g as boundaries, and rear side openings 21d1 and 21e1 on the ring-shaped connection side. Openings 21d2 and 21e2 are formed (see FIG. 5).

By making the openings 21d and 21e large, the weight of the rotor can be reduced. , since a large load acts thereon, it is preferable not to form an opening at least in a certain range of circular arc regions facing the support arms 11 and 12 . The semi-annular frames 21f and 21g may be formed along the upper edge of the cylindrical wall 21, but in this embodiment, they are formed below the upper edge of the cylindrical wall 21. Thus, deformation of the arc walls 21a and 21b is effectively prevented, and the following cover members are engaged to stabilize the cover members.

A cover member (cap-shaped cover member) 22A is attached to the surface of the bridge 20A. As shown in FIGS. 4 and 5, the cover member 22A includes a circumferential wall 22a and an annular flange portion (locking portion) 22b that protrudes radially outward from the upper opening edge of the circumferential wall to prevent thread dropout. , and a bottom portion 22c in which a substantially rectangular opening 22d is formed in the central region. The circumferential wall 22a is provided with a pair of arcuate walls 22a' that are arcuately suspended at two opposite locations. Essentially, in this embodiment, it can be attached to the bridge 20A via bosses 22e formed at four locations (there may be any number of locations, and the locations are not limited).

When the cover member 22A is attached to the bridge 20A, the bottom portion 22c of the cover member and the pair of arcuate walls 22a' extend both sides of the bridge 20A to the portions where the semi-annular frames 21f and 21g are formed. (front side openings 21d1 and 21e1) are closed (see FIGS. 6(b) and 7). That is, in the attached state of the cover member 22A, the lower circumferential wall 22a of the annular flange portion 22b abuts against the upper end edges of the arcuate walls 21a, 21b of the cylinder wall 21 and is locked. A pair of arcuate walls 22a' that hang down are brought into contact with the inner surfaces of the semi-annular frames 21f and 21g to close the front side openings 21d1 and 21e1 above the openings 21d and 21e. In the present embodiment, as described above, the substantially rectangular opening 22d is formed in the central region of the bottom portion 22c of the cover member 22A, and the surface of the bridge 20A is exposed at that portion, thereby overlapping the bridge 20A. The area of the bottom portion 22c can be reduced, and the weight of the front wall 22 can be effectively reduced.

A spool shaft is inserted through the center of the bridge 20A, and an opening 20a is formed for mounting a nut fixed to a pinion gear (drive shaft), which is a component of the driving force transmission mechanism. Four holes 20b are formed at positions corresponding to the bosses 22e of the cover member 22A (there may be any number of holes, and the positions are not limited). .

With respect to such a bridge 20A, the bottom 22c of the cover member 22A is brought into contact with the surface of the bridge 20A, and the bosses 22e protruding from the holes 20b are welded (see FIGS. 10 and 11). It is attached to the bridge 20A and forms the front wall 22 together with the bridge (see FIG. 4). In this state, as described above, the spaces (front side openings 21d1 and 21e1) between the semi-annular frames 21f and 21g on both sides of the bridge 20A are closed by the cover member 22A. The upper portion of the tubular wall 21 having the shape of the shape can efficiently achieve weight reduction and dust resistance.
With the configuration of the cylindrical portion 20 and the configuration of the cover member 22A as described above, it is possible to prevent thread dropping while reducing the weight of the rotor as much as possible.

The ring-shaped connecting portion 25 has the openings 21d and 21e formed in the tubular wall 21 of the tubular portion 20, so that both sides of the lower ends of the arc walls 21a and 21b of the tubular wall 21 form a semi-annular frame structure. The connected portion forms the ring-shaped connecting portion 25 and defines the opening at the rear end of the tubular portion 20 . In this case, both sides of the support arms 11 and 12 are integrally connected to a ring-shaped connecting portion 25 having a frame structure and are integrated together with the ring-shaped connecting portion 25 . As a result, the rotor main body 10A is effectively reinforced at the pair of support arms 11 and 12 on which a large load is applied, and it is possible to reduce the weight as much as possible while maintaining the necessary strength.
By varying the size of the openings 21d and 21e formed in the cylindrical wall 21 of the cylindrical portion 20, the wall thickness, surface shape, and cross-sectional shape of the ring-shaped connecting portion 25, the strength of the rotor can be varied. In addition, it is possible to effectively achieve weight reduction.

There are no particular restrictions on the method of connecting the two side portions of the support arms 11 and 12 and the ring-shaped connecting portion 25, and the connection position thereof. For example, in order to integrally connect both sides of the rear ends of the support arms 11 and 12 and the ring-shaped connecting portion 25 and further increase the rigidity of the support arms 11 and 12, from the rear ends of the support arms 11 and 12 It is possible to make appropriate modifications, such as integrally connecting the regions on both sides leading to the front. In particular, of the pair of support arms, the support arm 12 on the side where the fishing line guide device 50 is arranged receives a large load on the side surface opposite to the bail, as described above. It is preferable to reinforce

In this embodiment, between both sides of the support arms 11 and 12 and the ring-shaped connecting portion 25 which is the rear portion of the rotor, there is a reinforcing portion tapered from the rear end portion toward the side portion of the support arm. They are connected by forming 26a, 26b, 26c and 26d.

In this case, as shown in FIGS. 1 and 8, the support arm 11 on the side where the reversing mechanism is not provided is connected to both sides thereof with reinforcing portions 26a and 26b. The reinforcing portions 26a and 26b on both sides are formed in a bifurcated shape by opening the rear side (rear portion) of the support arm 11, and are connected to the ring-shaped connecting portion 25 as they are in a flat shape without a step. That is, a substantially rectangular opening 27 is formed between the reinforcing portions 26a and 26b, and the bail support member 14 is rotatably supported outside the support arm 11 above the opening. .
The support arm 11 may be formed in the shape of a single plate and connected flush with the ring-shaped connecting portion 25, and may have a structure in which reinforcing portions are formed on both sides thereof. A disk-shaped front end portion 11A is formed on the front side of the shaped reinforcement portions 26a and 26b, and the rotation support portion 14a of the bail support member 14 is rotatably attached thereto, thereby reducing weight. Rigidity can be increased.

As shown in FIGS. 2 and 9, the support arm 12 on the side where the reversing mechanism is arranged has ring-shaped connections on both sides from the rear end of the support arm to the support portion of the bail support member 15, as shown in FIGS. Reinforcing portions 26c and 26d extending toward the portion are connected. In this case, a substantially triangular opening 28 is formed between the reinforcing portion 26 d on the side opposite to the bail and the support arm 12 , and the reinforcing portion 26 d is bifurcated and connected to the ring-shaped connecting portion 25 . there is A rotation support portion 15a of the bail support member 15 is rotatably supported outside the upper tip portion 12A of the support arm 12. As shown in FIG.

As described above, the reinforcing portions 26a to 26d connected to the ring-shaped connecting portion 25 are formed in the supporting arms 11 and 12, so that the rigidity of the supporting arms 11 and 12 can be increased. By forming the openings 27 and 28 and tapering them forward, the weight of the rotor body can be reduced and the design can be improved. In this case, the edges defining the openings 27 and 28 may be formed in a direction perpendicular to the surface of the support arm, but as in the present embodiment, the edges may be inclined so as to gradually widen from the inside to the outside. By forming the surfaces (slanted edges 27a and 28a), the design is improved, and the fishing line is less likely to get entangled, making it possible to effectively prevent line breakage and the like. In addition, since the reinforcing portions 26a and 26b on both sides of the support arm 11 are connected to the ring-shaped connecting portion 25 in a flush shape without steps, the thread is not easily entangled and the thread is not entangled. will also come off easily.

The mounting method for rotatably supporting the bail support members 14 and 15 on the support arms 11 and 12 is as shown in FIG. The rotation support portions 14a and 15a of the support members 14 and 15 are brought into contact with each other, and as indicated by the arrow D2, the attachment member (in this embodiment, insert This is done by tightening a member 30 (a member in which an E-shaped snap ring is attached to a molded pin) (the support arm 11 side is also fixed in the same way; see FIG. 11). In this case, U-shaped recesses 11a and 12a are formed on the inner surfaces of the support arms 11 and 12 on the tip side, respectively, so that the head of the attachment member 30 inserted from the inside does not protrude. It is

As a result, the attachment member 30 is not exposed from the outer surfaces of the support areas of the bail support members 14 and 15, and the outer surfaces of the bail support members can be made smooth, making it difficult for fishing line to get entangled. can.

A cover member 12B for closing the reversing mechanism housed in the support arm 12 has a boss 12d formed on its inner surface, as shown in FIG. The boss 12d is formed with a female threaded portion (it may be configured to screw a tapping screw) into which the mounting member 35 is screwed from the radially inner side in the direction of arrow D3 in FIG. , the cover member 12B is attached to the support arm 12. As shown in FIG. For this reason, a screw hole 12d' is formed at a position corresponding to the boss 12d of the attached cover member 12B in the bottom surface of the concave portion 12B' that accommodates the reversing mechanism of the support arm 12. By tightening the fixing member 35 in the D3 direction, the cover member 12B is attached to the support arm 12, and the reversing mechanism provided in the concave portion 12B' is closed.

In this case, as shown in FIG. 5, openings 21h and 21i are formed in the circular arc walls 21a and 21b of the cylindrical wall 21 of the rotor so that the mounting member 35 can be easily fixed. I have to. That is, in a state in which the cover member 12B is attached to the support arm 12 housing the reversing mechanism, the mounting member 35 and a jig (not shown) for fixing the mounting member 35 are attached to the opening 27 of the support arm 11 and the tubular wall 21 of the rotor. The cover member 12B can be easily inserted through the openings 21h and 21i of the cover member 12B.

As a result, the attachment member 35 is not exposed from the outer surface of the cover member 12B attached to the support arm 12, and the outer surface can be made smooth, making it difficult for the fishing line to get entangled.
Further, in the configuration described above, a plurality of openings 21d, 21e, 21h, and 21i are formed in the tubular wall 21 of the tubular portion 20 of the rotor, and through the reinforcing portions 26a, 26b, 26c, and 26d. Since the ring-shaped connecting portion 25 and the support arms 11 and 12 are integrated into a frame structure, the strength can be maintained and the weight can be reduced as much as possible. In particular, the portions of the support arms 11 and 12 on which a large load acts are reinforced by the arcuate walls 21a and 21b, and are connected to the reinforcing portions 26a, 26b, 26c and 26d by the ring-shaped connecting portion 25. Therefore, the balance is good and the strength can be improved.

10 and 11, the rear portion of the rotor 10 is centered about the axis X of the drive shaft except for the installation area of the reversing mechanism disposed on the support arm 12. It is formed in a smooth circular ring shape without steps. In this way, the rear portion of the rotor 10 is formed in a stepless circular ring shape centering on the axial center X of the drive shaft, so that even if the fishing line becomes entangled in the rear portion of the rotor from the spool during actual fishing, it can be easily removed. At the same time, it is possible to suppress and prevent yarn entanglement in the rear portion of the rotor. In the present embodiment, the ring-shaped connecting portion 25 is divided at the rear end portion of the support arm 12. However, the circular shape without any step is prevented from interfering with this portion of the cover member 12B. can be configured to

Also, the rear portion of the rotor, which is formed in a circular ring shape, has an outer surface shape that expands in diameter as it moves forward. That is, on the outer side of the ring-shaped connecting portion 25 of the present embodiment, between the support arms 11 and 12, a curved wall 25a is integrally formed so as to extend radially outward along the ring-shaped connecting portion 25. It is formed so as to increase in diameter as it moves forward from the inner edge 25' of the portion 25. As shown in FIG. By forming the curved wall 25a in this way, even if the fishing line gets entangled, it can easily slide forward, and it is possible to more effectively suppress or prevent the line from getting entangled in the rear part of the rotor.

In addition, in this embodiment, the outer surfaces of the support arms 11 and 12 are connected to the circular ring-shaped outer surface of the rear portion of the rotor without steps. That is, the ring-shaped connecting portion 25 is integrated with the reinforcing portions 26a to 26d. They are connected with a smooth surface shape that gradually expands forward from the inner edge 25'. As a result, the fishing line can be easily removed from not only the rear portion of the rotor but also the support arms 11 and 12, and tangling of the line can be suppressed.

According to the spinning reel for fishing having the rotor 10 as described above, an opening is formed in the cylindrical wall 21 of the cylindrical portion 20 of the rotor 20, and the bridge 20A defining this opening and the Since the front wall 22 of the cylindrical portion is formed by the cover member 22A, the weight of the rotor can be reduced and the yarn drop can be suppressed. , thread entanglement can be effectively prevented. Further, the main body 10A of the rotor is provided with a ring-shaped connecting portion 25 for connecting the pair of support arms 11 and 12, a wide opening is formed in the cylindrical portion, and the rotor is reinforced with a reinforcing portion, thereby reducing the weight of the rotor. The strength can be improved while achieving Further, attachment members 55, 30, and 35 for attaching the fishing line guide portion 53, the bail support members 14 and 15, and the cover member 12B are attached to the rotor 10 and the bail support member 14 including the cover member 12B. Since it is arranged so as not to be exposed from the outer surface, it is possible to effectively prevent line entanglement when reeling in/releasing the line during actual fishing.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and can be modified in various ways.
For example, the shapes of the support arms 11 and 12 and the bail support members 14 and 15 shown in the drawings are merely examples, and can be modified as appropriate. In this case, the shape of the exposed portion may have unevenness on the surface as long as it is difficult for the fishing line to get caught on it, or if it comes off easily even if it gets caught on it. Regarding the opening formed in the tubular wall 21 of the tubular portion 20 of the rotor, if the strength can be secured by the ring-shaped connecting portion 25 and the reinforcing portions 26a, 26b, 26c, and 26d, the shape, the number of formed portions, and the formed positions are determined. can be modified as appropriate. Also, if necessary, an opening other than the above-described configuration may be formed. Further, the locking portion formed on the cover member 22A may be any one that protrudes in the radial direction from the cylindrical wall 21 of the cylindrical portion 20 to prevent the thread from falling off, and the shape thereof may be changed as appropriate. It is possible.
