Description

  The present invention relates to a structure of a fishing rod, specifically, a blank head portion constituting a fishing rod. The present invention also relates to the structure of a mouth fitting that is attached to the periphery of a blank mouth that constitutes a fishing rod. Furthermore, the present invention relates to a structure of a plug fitted to a blank muzzle constituting a fishing rod.

  A fishing rod is generally composed of a plurality of blanks having different outer diameters and inner diameters, and each blank is connected in the longitudinal direction to form a fishing rod having a predetermined length. When the fishing rod is composed of n blanks, the blanks are referred to as No. 1 and No. 2 in order from the smallest outer diameter, and the blank with the largest outer diameter is the original clause. The blank adjacent to is called the original upper section.

  The connection method of each blank is generally a swing-out method or a splicing method. In the withdrawal method, each blank is combined in a so-called nested manner, the first segment is extracted from the second segment, the second segment is extracted from the third segment, and similarly, among the adjacent blanks The fishing rod is extended by pulling out the small-diameter blank from the large-diameter blank. In the splicing method, the rear end portion of the small-diameter blank is fitted to the front end portion of the large-diameter blank to form an elongated fishing rod.

  When a fishing rod is not used, each blank is stored in a nested manner in adjacent large diameter blanks. In this state, there is a case where a plug is attached to the tip of the original clause (for example, see Patent Document 1). This plug prevents the blank stored in the original clause from popping out of the original clause when the fishing rod is in the stored state.

  When a fishing rod is used, the rear end of one blank and the front end of the other blank are fitted together. In order to ensure that each blank is maintained in the extended state and the performance of the fishing rod is exhibited, it is necessary to securely fit each blank. Therefore, the tip of each blank may be reinforced. Specifically, the thickness of the tip may be increased, and a tip fitting may be attached to the tip (for example, Patent Document 2). 3).

  In actual fishing, quick deployment and withdrawal of tools at fishing grounds is required. Therefore, it is desirable that the spigot can be easily and quickly attached to and detached from the fishing rod by the angler. Furthermore, it is desirable that each blank constituting the fishing rod can be easily and quickly connected by the angler and can be disconnected.

  The angler picks and plugs the plug with a finger when inserting or removing the plug. Since the size of the plug corresponds to the outer diameter of the original section, it is not inherently easy for the angler to pick. For this reason, the angler's hand is slippery with respect to the plug, and moreover, water is often attached to the fishing rod and the angler's hand at the fishing spot. For this reason, it may be difficult to attach and detach the plug.

  The angler operates both blanks while holding the leading edge of one blank with one hand and the trailing edge of the other blank with the other hand during the operation of connecting and releasing the connection of each blank. To do. At this time, the hand is slippery with respect to each blank, and the water is often attached to the fishing rod and the hand of the fisherman at the fishing spot. For this reason, in particular, the connection release operation of each blank at the time of withdrawal (that is, the storage operation of the fishing rod) may not be easy.

  As described above, in the conventional fishing rod, the above-mentioned ball fitting may be attached to each blank. This ball-and-mouth fitting bears reinforcement of the connection part of each blank, but this improves the mechanical strength (especially bending rigidity) of the said connection part locally. Therefore, there is a disadvantage that the designed performance (so-called tone) of the fishing rod is difficult to be maintained. Therefore, in order to eliminate this inconvenience, it is necessary to suppress an increase in the local rigidity of the blank due to the provision of the ball fitting.

  The present invention has been made based on such a background, and a first object thereof is to provide a fishing rod plug that can be easily attached and detached. In addition, a second object of the present invention is to provide a fishing rod that can easily connect and disconnect each blank, and a lug fitting that is used for such a fishing rod and does not change the condition of the fishing rod. It is to be.

  (1) A fishing rod spigot according to the present invention comprises an elastic body that has one end portion and the other end portion, and the one end portion is press-fitted into a blank muzzle constituting a fishing rod, thereby closing the muzzle. A plug body and an operation cap fitted to the other end portion of the plug body are provided, and a window portion for exposing a part of the other end portion of the plug body is formed on the peripheral surface of the operation cap.

  According to this configuration, for example, a fisherman can pick up the operation cap and press-fit the plug body into the blank mouth. Since the window part is provided in the surrounding surface of the operation cap, this window part functions as a slipper when the angler picks the operation cap.

  (2) It is preferable that a convex portion is formed on the peripheral surface of the stopper body, and the convex portion is fitted to the window portion of the operation cap.

  In this configuration, since the operation cap is prevented from rotating with respect to the plug body, the work of press-fitting the plug body into the mouth becomes easier.

  (3) The operation cap may be fixed to the plug body with an adhesive. In that case, it is preferable that the adhesive adhered to the plug body is exposed from the window.

  In this configuration, the adhesive is applied to the entire plug body, and the operation cap is put on the plug body, so that both are fixed. When the adhesive is dried and the operation cap is fixed to the stopper body, the solidified adhesive is exposed from the window portion. This solidified adhesive functions as a slip stopper when the angler picks the operation cap.

  (4) The head fitting according to the present invention has a metal cylindrical main body that is externally fitted to a blank head of a fishing rod, and penetrates the peripheral surface of the metal cylindrical main body. A plurality of windows are uniformly distributed. The shape of the window portion is formed so as to uniformly reduce the bending rigidity of the metallic cylindrical main body.

  The ball fitting is fitted into the tip of the blank so as to surround the periphery of the ball. This reinforces the peripheral edge of the blank. However, since the window portion is provided in the ball fitting, the bending rigidity of the ball fitting is uniformly reduced. Therefore, when the end fitting is attached to the blank, it is avoided that the bending rigidity of the portion is locally increased while the compressive strength of the periphery of the end is improved.

  (5) It is preferable that a concave strip that can be engaged with the blank is formed on the inner peripheral surface of the metallic cylindrical main body.

  In this configuration, the rotation of the metal cylindrical main body relative to the blank is restricted, and the metal cylindrical main body is positioned on the blank. Therefore, the metal cylindrical main body is firmly fixed to the blank.

  (6) A fishing rod according to the present invention comprises a fishing rod main body having a plurality of blanks, each of which is connected in the longitudinal direction, and a metal cylindrical member externally fitted to the mouth of the blank. A notch window portion that exposes the blank is formed on the peripheral surface of the metallic cylindrical member.

  According to this configuration, a fishing rod having a predetermined length is formed by connecting the blanks in the longitudinal direction. Each blank is connected by a swing-out type or a joint type. A metal cylindrical member is fitted into each blank, and the periphery of the mouth is covered with the metal cylindrical member. Thereby, the connection part of each blank is reinforced and compressive strength improves. Since the notch window part is provided in the metallic cylindrical member, the improvement in the bending rigidity of the peripheral part of the head is suppressed while the compressive strength of the peripheral part of the head is improved. Therefore, even if a metal cylindrical member is provided, the tone of the fishing rod is not greatly changed. Furthermore, the notch window portion functions as a slip stopper when the angler operates the blank to extend and retract the fishing rod.

  (7) The metallic cylindrical member may be fixed to the blank via an adhesive. In that case, it is preferable that the adhesive adhered to the blank is exposed from the cutout window.

  In this configuration, the adhesive is applied to the entire periphery of the edge of the blank, and the both ends are secured by being covered with the metallic member in the periphery of the edge of the mouth. In a state where the adhesive is dried and the metal cylindrical member is fixed to the blank, the solidified adhesive is exposed from the cutout window. This solidified adhesive functions as a slip stopper when the angler operates the blank.

  (8) The notched window portion is disposed uniformly through the peripheral surface of the metal cylindrical main body, and the shape of the window portion is the bending rigidity of the metal cylindrical main body. It is preferably formed so as to be lowered uniformly.

  In this configuration, the bending rigidity of the metallic cylindrical member is uniformly reduced. Therefore, when a ball fitting is attached to the blank, the bending rigidity of the portion is improved while the compressive strength of the periphery of the mouth is improved. Local growth is avoided. Therefore, the tone of the fishing rod designed in advance is maintained.

  (9) Concave ridges are formed on the inner peripheral surface of the metal cylindrical member, and convex ridges that engage the concave ridges are provided on the outer peripheral surface of the blank. It is preferable that the rotation of the metal cylindrical member with respect to the blank is restricted by the engagement.

  In this configuration, rotation of the metal cylindrical member relative to the blank is restricted, and the metal cylindrical member is positioned on the blank. Therefore, the metal cylindrical main body is firmly fixed to the blank.

  According to the fishing rod spigot according to the present invention, the operation cap exhibits a non-slip effect, so that even if the angler's hand is wet in actual fishing, for example, the angler can easily grasp the operation cap. A fishing rod plug can be attached to and detached from the fishing rod.

  According to the fishing rod fork according to the present invention, the fishing rod fork is mounted on the periphery of the blank, so that the compressive strength of the periphery of the tip is improved and local bending rigidity is provided. Can be suppressed. As a result, it is possible to reinforce the periphery of the mouth and maintain the condition of the fishing rod while suppressing an increase in the weight of the fishing rod.

  According to the fishing rod of the present invention, the strength of the fishing rod is improved because the peripheral portion of each blank is reinforced. And since the notch window part is provided in the metal cylindrical member which reinforces the said muzzle periphery part, the weight increase by reinforcement is suppressed. Further, since the notch window portion is provided, the bending rigidity of the peripheral portion of each blank is not increased locally, so that the tone of the fishing rod designed in advance is maintained.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings as appropriate.

<First embodiment (plug)>

  FIG.1 and FIG.2 is an external appearance perspective view of the stopper 10 which concerns on one Embodiment of this invention. FIG. 3 is an exploded perspective view of the plug 10.

  This plug 10 (an example of “a fishing rod plug” described in claims) is attached to a fishing rod having a plurality of blanks. Specifically, in the state in which the fishing rod is stored, by attaching the plug 10 to the head of the original clause, it is possible to prevent other blanks from jumping out of the original clause.

  The plug 10 has a plug body 11 and an operation cap 12. The operation cap 12 is fitted into the other end portion 13 of the plug body 11, and therefore the distal end portion 14 of the plug body 11 protrudes from the operation cap 12. The distal end portion 14 of the plug main body 11 is press-fitted into the muzzle of the original section.

  In this embodiment, the plug body 11 is made of acrylonitrile-butadiene rubber (NBR). But the material which comprises the plug main body 11 is not limited to this, It can be comprised by resin other elastic bodies other than other rubber | gum.

  The plug body 11 is formed in a cylindrical shape as shown in FIG. The outer diameter of the plug main body 11 is determined in accordance with the size of the original knot (the inner diameter of the ball opening) to which the plug 10 is attached. The external shape of the plug body 11 is not limited to a cylindrical shape, and may be formed in a columnar shape having a polygonal cross-sectional shape, for example. In that case, as for the cross-sectional shape of the plug body, it is only necessary that the envelope connecting the vertices is circular, and the diameter thereof corresponds to the inner diameter of the above-mentioned head.

  A concave strip 15 is provided on the outer peripheral surface of the plug body 11. The recess 15 is formed as a groove extending along the axial direction of the plug body 11. The inner surface of the recess 15 is formed in an arc shape. The recess 15 extends from the one end surface 16 of the plug body 11 to the center of the plug body 11. In the present embodiment, three concave strips 15 are provided in the plug body 11, and each concave strip 15 is evenly distributed in the circumferential direction of the plug body 11. In addition, the inner surface shape of the concave strip 15 is not limited to the arc shape, and may be another shape (for example, a rectangular shape). Further, the number of the concave stripes 15 is not limited to three, and the concave stripes 15 may be omitted. By providing the concave strip 15, the contact area between the main node and the plug body 11 is reduced, and therefore, the plug 10 is prevented from being fixed to the main node and the attachment / detachment operation is simplified. .

  A through hole 17 is provided in the plug body 11. The through hole 17 extends from one end surface 16 of the plug body 11 along the central axis of the plug body 11. Since the through-hole 17 is provided, the plug body 11 is easily deformed in the radial direction, and therefore, the work of fitting the plug 10 into the base joint is facilitated. However, the through hole 17 may be omitted.

  The operation cap 12 includes a ring member 18 and a lid 19.

  In this embodiment, the ring member 18 is made of an aluminum alloy. But the material which comprises the ring member 18 is not limited to an aluminum alloy, Resin can be employ | adopted besides brass, stainless steel, a magnesium alloy, other metals. As shown in FIGS. 1 to 3, the ring member 18 is externally fitted to the other end portion 13 of the plug body 11. The ring member 18 is formed in a cylindrical shape, and a window portion 21 is provided on the side wall 20 (an example of a “circumferential surface” recited in the claims). Thereby, a part of the other end portion 13 of the plug body 11 is exposed from the window portion 21. The outer shape of the ring member 18 is not limited to a cylindrical shape, and may be formed in a shape corresponding to the outer shape of the other end portion 13 of the plug body 11.

  The wall thickness dimension of the ring member 18 is set to 0.3 mm in this embodiment. But the thickness dimension of the ring member 18 may be set in the range of 0.25 mm-0.5 mm. In the present embodiment, the four window portions 21 are provided in the ring member 18, and the window portions 21 are evenly distributed in the circumferential direction of the ring member 18. In addition, the number of the window parts 21 can be appropriately set in the range of 2 to 12. Furthermore, in this embodiment, the shape of the window part 21 is formed in the rectangle. However, the shape of the window portion 21 is not limited to a rectangle, and a circle, an ellipse, or other shapes may be employed.

  The lid 19 is attached to the end surface 22 of the ring member 18. The lid 19 is formed in a disk shape in the present embodiment, and is disposed so as to close the end surface 22 of the ring member 18. The material of the lid 19 is the same as that of the ring member 18, but a resin or other material may be employed. The outer surface of the lid 19 may be decorated, or the specifications of the fishing rod to which the plug 10 is attached may be displayed. The lid 19 may be omitted.

  The plug 10 is assembled by fitting the operation cap 12 into the plug body 11. Specifically, for example, an adhesive is applied to the inner surface of the ring member 18, and the ring member 18 is fitted into the other end portion 13 of the plug body 11. The ring member 18 is fixed to the plug body 11 by the adhesive.

  As described above, the plug 10 is fitted into the main section of a fishing rod. At this time, the angler picks up the operation cap 12 with a finger and inserts the plug body 11 into the head of the main section. Since the outer diameter of the one end portion 14 of the plug body 11 corresponds to the inner diameter of the muzzle of the original knot, the plug main body 11 is press-fitted into the knot and securely attached. Since the ring member 18 is provided with the window portion 21, a step is formed between the operation cap 12 and the plug body 11. This step size corresponds to the thickness of the ring member 18. And this level | step difference functions as a slipper when a fisherman picks the operation cap 12, Therefore Even if a hand is wet, the fisherman can attach or detach the plug 10 with respect to a fishing rod easily.

<First Modification of First Embodiment>

  FIG. 4 is an external perspective view of a plug 30 according to a first modification of the present embodiment. FIG. 5 is an exploded perspective view of the plug 30. 6 is a cross-sectional view taken along the line VI-VI in FIG.

  The plug 30 according to this modification differs from the plug 10 according to the first embodiment in that the operation cap 12 is simply fitted into the plug body 11 in the plug 10. In the plug 30 according to this modification, the plug body 11 is provided with a convex portion 31, and the convex portion 31 is fitted to the window portion 21 of the ring member 18. Other configurations are the same as those of the plug 10.

  The convex portion 31 is formed integrally with the stopper body 11 at the other end 13 of the stopper body 11. In this modification, four convex portions 31 are provided on the plug body 11. Each convex portion 31 protrudes from the other end portion 13 of the plug body 11 and protrudes in the radial direction. The convex portions 31 are uniformly distributed on the peripheral surface of the plug body 11. The outer shape of each convex portion 31 corresponds to the shape of the window portion 21 provided in the ring member 12, and each convex portion 31 is fitted into the corresponding window portion 21.

  In the present embodiment, the height dimension of each convex portion 31 corresponds to the thickness dimension of the ring member 18. Therefore, as shown in FIGS. 4 and 6, each convex portion 31 is fitted into the window portion 21 in a state where the operation cap 12 is fitted into the plug body 11, and both are in a so-called flush state. That is, no step is generated between the window portion 21 and the plug body 11. Even when the step does not occur as described above, since the ring member 18 is made of metal, a certain antiskid effect is exhibited. However, the height dimension of the convex portion 31 may be adjusted so that a step is formed between the window portion 21 and the plug body 11.

  According to the spigot 30 according to this modification, the operation cap 12 is prevented from rotating with respect to the plug main body 11 by fitting the convex portions 31 with the upper window portion 21. Therefore, the plug main body 11 does not rotate in the work of attaching the plug 30 to the fishing rod by the angler, and therefore the work of press-fitting the plug 30 into the fishing hole of the fishing rod becomes easier.

<Second Modification of First Embodiment>

  FIG. 7 is an external perspective view of a spigot 40 according to a second modification of the present embodiment.

  The plug 40 according to this modification differs from the plug 10 according to the first embodiment in that the operation cap 12 is simply fitted into the plug body 11 in the plug 10. In the plug 40 according to this modification, the step portion formed between the plug body 11 and the window portion 21 of the operation cap 12 is filled with the adhesive 41. Other configurations are the same as those of the plug 10.

  Although the kind of the said adhesive agent 41 is not specifically limited, In this embodiment, 2 liquid mixing type epoxy-type adhesive agent can be employ | adopted. In this modification, when the spigot 40 is assembled, a sufficient amount of adhesive 41 is applied around the other end portion 13 (see FIG. 3) of the plug main body 11. When the operation cap 12 is fitted into the plug member 11 in this state, the operation cap 12 is fixed to the plug body 11 and the dried adhesive 41 is exposed from the window portion 21 of the operation cap 12. Note that the adhesive 41 may be applied so as to fill the window portion 21 after the operation cap 12 is fixed to the plug body 11 in the same manner as the plug 10 according to the first embodiment.

  When the adhesive 41 is dried in the plug 40, the solidified adhesive 41 is exposed from the window portion 21 of the operation cap 12. The adhesive 41 functions as a slip stopper when the angler picks the operation cap 12. Therefore, even if the hand is wet, the angler can pick and remove the plug 10 from the fishing rod.

<Second embodiment (fishing rod)>

  FIG. 8 is a front view of a fishing rod 50 according to an embodiment of the present invention.

  The fishing rod 50 includes a fishing rod main body 51 and a grip 52.

  The fishing rod main body 51 is configured by connecting a plurality of blanks. That is, the fishing rod main body 51 includes a first node 53, a former upper node 54, and a former node 55, which are connected in the longitudinal direction. Each blank is constructed by a known manufacturing method. That is, for example, a carbon fiber reinforced resin sheet (so-called prepreg) is wound around a mandrel and fired into a cylindrical shape by performing a required heat treatment. In order to simplify the explanation, the illustration of a part of the first clause 53 and the former upper clause 54 is omitted in the figure. In the present embodiment, the first node 53 and the original upper node 54 and the original upper node 54 and the original node 55 are connected by a so-called stamped joint. Needless to say, the blanks may be connected to each other in a joint form other than the seal joint. In the figure, a connecting portion 56 of the original upper section 54 and the original section 55 is shown.

  A plurality of line guides 57 are arranged at predetermined intervals in the first node 53, the former upper node 54, and the former node 55. The line guide 57 is inserted with a fishing line extending from a fishing reel attached to the grip 52, and supports the fishing line. The rear end portion of the main section 55 is inserted into the grip 52, whereby the fishing rod main body 51 is supported by the grip 52. The grip 52 is gripped by a fisherman and includes a front portion 58 and a rear end portion 59. A reel sheet 60 is formed between the front portion 58 and the rear end portion 59. The reel seat 60 can sandwich the legs of the fishing reel so that the fishing reel is securely fixed to the grip 52.

  FIG. 9 is an enlarged perspective view of a main part of the fishing rod 50 and shows the structure of the connecting portion 56 in detail.

  A core 61 is projected from the rear end 63 of the upper upper section 54. When the core 61 is fitted into the inner section 55, the original section 55 and the upper upper section 54 are connected to each other by an inlay joint. The A ball end fitting 64 (an example of a “metal tubular member” recited in the claims) is mounted on the ball opening 62 of the original section 55. Also, a ball fitting 64 is attached to the rear end portion of the former upper section 54. Therefore, the two upper end fittings 64 are opposed to each other by connecting the original upper section 54 to the original section 55.

  The ball fitting 64 is made of an aluminum alloy in the present embodiment. But the material which comprises the ball end metal fitting 64 is not limited to an aluminum alloy, A brass, stainless steel, a magnesium alloy, and another metal can be employ | adopted. As shown in FIGS. 8 and 9, the ball fitting 64 is externally fitted to the rear end portion of the original upper section 54 and the ball opening 62 of the original section 55. The ball fitting 64 is formed in a cylindrical shape, and a notch window 66 is provided on the side wall 20 (an example of a “circumferential surface” recited in the claims). As a result, the peripheral edge portion of the mouth end 62 of the original knot 55 and the rear end portion of the former upper knot 54 are exposed from the cutout window 66.

  The wall thickness of the ball fitting 64 is set to 0.3 mm in this embodiment. However, the wall thickness of the ball fitting 64 can be set in the range of 0.25 mm to 0.5 mm. In the present embodiment, eight notch windows 66 are provided in the ball fitting 64. Specifically, the notch windows 66 are equally distributed in four places in the circumferential direction of the ball fitting 64 and are arranged in two rows in the longitudinal direction. In addition, the number of the notch window parts 66 is not specifically limited, It can be arrange | positioned uniformly by the circumferential direction, and may be arrange | positioned at a longitudinal direction at about 1-5 rows.

  Furthermore, in this embodiment, the shape of the notch window 66 is formed in a rectangle. By forming the cutout window 66 in a rectangular shape in this way, the ball fitting 64 is formed in a bowl shape, and the annular portions wound in the circumferential direction are arranged in three rows at predetermined intervals in the longitudinal direction. In addition, the four columnar portions that connect the annular portions are equally arranged in the circumferential direction. By forming the notch window 66 in such a bowl shape, the radial compressive strength of the ball fitting 64 is not greatly reduced as compared to the case without the notch window 66, but the bending rigidity in the longitudinal direction is large. And it decreases uniformly. The effect of forming the ball fitting 64 in the shape of a bowl will be described later. In addition, the shape of the notch window portion 66 is not limited to a rectangle, and as described above, the bending rigidity in the longitudinal direction can be uniformly reduced while securing the compressive strength in the radial direction of the ball fitting 64. If possible, circular, elliptical, or other shapes may be employed.

  In the present embodiment, a bottom wall 67 is formed on the end surface 22 of the end fitting 64. A circular through hole 68 is provided in the bottom wall 67. The inner diameter of the through hole 68 corresponds to the outer diameter of the joint 61. Accordingly, the core 61 passes through the bottom wall 67 of the ball fitting 64 in a state where the ball fitting 64 is attached to the original upper joint 54. On the other hand, a fitting hole 70 is provided in the distal end surface 69 of the base joint 55. The fitting hole 70 is formed along the longitudinal direction from the distal end of the main node 55, and the inner diameter thereof corresponds to the outer diameter of the core 61 of the original upper node 54. Therefore, when the ball fitting 64 is attached to the base joint 55, the fitting hole 70 is exposed through the through hole 68. The bottom wall 67 may be omitted.

  The ball fitting 64 is attached to the original upper section 54 and the original section 55 by an adhesive, for example. Specifically, an adhesive is applied to the inner surface of the ball fitting 64, and the ball fitting 64 is fitted so as to cover the rear end portion of the original upper section 54 and the ball opening 62 of the original section 55. With this adhesive, the ball fitting 64 is fixed to the original upper section 54 and the original section 55.

  In this fishing rod 50, a ball fitting 64 is fitted into the rear end portion of the former upper joint 54 and the mouth 62 of the former clause 55, and the peripheral portion of the mouth 62 is covered with the ball fitting 64. Thereby, especially the compressive strength of the mouthpiece 62 of the original clause 55 is improved, and the connecting portion 56 between the original upper clause 54 and the original clause 55 is reinforced. Since the notched window portion 66 having the above shape is provided in the ball end fitting 64, the improvement of the bending rigidity of the peripheral portion of the ball outlet 62 can be suppressed while the compressive strength of the peripheral portion of the ball opening 62 is improved. Therefore, even if the ball fitting 64 is attached to the fishing rod main body 51, there is an advantage that the tone of the fishing rod 50 is not greatly changed.

  In addition, by providing the cutout window portion 66, a step is formed between the cutout window portion 66 and the original upper section 54 or the original section 55. This level difference functions as an anti-slip when the angler grips the original upper section 54 and the original section 55 by hand and connects or disengages them. Therefore, the angler can easily connect or disconnect the original upper section 54 and the original section 55 even if the hand is wet.

<First Modification of Second Embodiment>

  FIG. 10 is an enlarged exploded perspective view of a main part of a fishing rod according to a first modification of the present embodiment.

  The fishing rod according to this modification is different from the fishing rod 50 according to the above-described embodiment in the structure of the connecting portion 56 between the original upper section 54 and the original section 55.
