In this fishing rod, a weight can be attached and attached to the rear part of the rod appropriately, so the center of gravity position of the fishing rod can be shifted to the rod side, contributing to improving the throwing operability and eliminating the feeling of weight To do.

Japanese Utility Model Publication No. 5-36376

  In the conventional fishing rod, since the weight is inserted into the rod, it is necessary to make the outer shape of the weight smaller than the inner diameter of the rod. With such a weight, the position of the center of gravity is as far back as possible. It was difficult to shift to the side. Further, when a plurality of weights are connected to obtain a necessary weight, the weight tends to shift toward the tip side, and it is difficult to shift the center of gravity position to the rear side as much as possible.

  The present invention has been made to solve the above problems, and provides a fishing rod that can shift the center of gravity position to the rear as much as possible and can hold the weight firmly. Let it be an issue.

The fishing rod of the present invention that solves such a problem includes a rod, a butt plug that can be screwed to a rear end portion of the ridge, and a shaft of the rod that can be held by the butt plug. An annular balance means capable of adjusting the weight balance in the direction, and a flexible member, is attached to the outer periphery of the rear end portion and extends rearward of the rear end portion, and the bottom plug and the balance means are arranged. And a bottom portion with which the balance means abuts is formed in the hollow portion, and an opening for inserting the bottom plug and the balance means into the hollow portion is provided at the rear end portion. comprises a bottom cylindrical grip, the inner peripheral surface of the hollow portion, the peripheral portion of the balancing means is provided comprising a possible press-an inner diameter, said bottom of said hollow portion, said balancing means It is provided to face the front part of the Can be brought into contact with the front portion of the balance means that has been pushed in and moved in the axial direction of the collar, and the balance means is tightened by screwing the butt plug into the inner periphery of the grip portion. It is press-fitted and clamped between the surface and the bottom and the bottom plug.

According to this fishing rod, the balance means can be attached to the rear end portion via the bottom plug by holding the annular balance means on the bottom plug and screwing the bottom plug to the rear end portion of the rod. .
The bottomed cylindrical grip portion attached to the outer periphery of the rear end portion is made of a flexible member, and includes a hollow portion that extends rearward of the rear end portion and in which the bottom plug and the balance means are disposed, and the hollow portion is Since the inner peripheral surface is provided with an inner diameter that allows the peripheral portion of the balance means to be press-fitted, the inner peripheral surface of the hollow portion is elastically elastic to the peripheral portion of the balance means when the bottom plug holding the balance means is screwed. The balance means is suitably held in the radial direction by the contact of the inner peripheral surface.

  On the other hand, the bottom portion of the hollow portion is provided to face the front portion of the balance means, and can come into contact with the front portion of the balance means that has been slidably moved in the axial direction of the collar by screwing the bottom plug. Therefore, when the butt plug holding the balance means is screwed to the rear end, the bottom of the hollow portion abuts elastically against the front of the balance means, and the balance means It is suitably held in the (tip direction).

  Therefore, the balancing means is held simultaneously in the radial direction and the axial direction by the inner peripheral surface and the bottom portion of the hollow portion by tightening the bottom plug by screwing, and the inner peripheral surface and the bottom portion of the hollow portion. And is clamped by being press-fitted between the bottom plug.

  In addition, the present invention includes a region in which an elastic member is disposed between the rear end portion and the bottom portion, and the bottom portion is positioned behind the rear end portion by this region. Good.

  By configuring in this way, the bottom portion is located behind the rear end portion by the region where the elastic member is disposed, so that the balance means is arranged behind the rear end in the axial direction of the bag. Can do.

  In the present invention, it is preferable that the balance means elastically deforms the facing surface of the bottom portion by tightening the bottom plug by screwing.

  With this configuration, when the butt plug is screwed to the rear end portion and tightened, the balance means comes into contact with the opposed surface at the bottom and the opposed surface is elastically deformed. It will be suitably held in the axial direction of the heel (tip direction).

  In the present invention, it is preferable that the butt plug includes a shaft portion and a head portion, and the balance means has a configuration in which the peripheral portion protrudes from the head portion toward the inner peripheral surface. .

  By adopting such a configuration, in the hollow portion, the peripheral portion protrudes from the head toward the inner peripheral surface, and the inner peripheral surface is in a state of reliably contacting the peripheral portion with elasticity. Therefore, the balance means is suitably held in the radial direction.

  Further, according to the present invention, the balance means is composed of a plurality of annular members that can be combined in the axial direction of the heel, and the front part of the annular member disposed on the bottom side among these is another member. It is good to set it as the structure which protrudes toward the said bottom part side rather than the said annular member, and the surrounding part protrudes toward the said inner peripheral surface rather than the said other annular member.

  According to this configuration, the annular member disposed on the bottom side of the plurality of annular members is suitably held in the radial direction with the inner peripheral surface of the hollow portion elastically contacting the peripheral portion, and the bottom portion Is elastically abutted on the front part and is suitably held in the axial direction of the heel. Therefore, this annular member is held by the inner peripheral surface and the bottom portion of the hollow portion simultaneously in two directions, ie, the radial direction and the axial direction, by tightening the bottom plug by screwing. And is clamped by being press-fitted between the bottom plug.

According to the present invention, the balance means is held by the inner peripheral surface and the bottom portion of the hollow portion in contact with each other in the radial direction and the axial direction at the same time by tightening the bottom plug by screwing. Since it will be press-fitted and clamped between the inner peripheral surface and the bottom of the bag and the butt plug, the balance means will be firmly held behind the rear end of the heel, such as when throwing Further, it is possible to suitably prevent the balance means from rattling.
Moreover, since the balance means is held behind the rear end portion, it is not limited by the inner diameter dimension of the heel as in the conventional case, which is inserted into the rear portion inside the heel. . Therefore, the balance means can be formed larger in the radial direction than the outer diameter of the rear end portion of the heel, and the position of the center of gravity can be shifted to the rear side as much as possible. Further, since the balance means is held behind the rear end portion, the center of gravity position of the heel is not shifted to the tip side due to the weight of the balance means, and the center of gravity position is made as much as possible compared to the conventional case. It can be shifted backward.

Further, according to the present invention, since the balance means can be disposed behind the heel in the axial direction from the rear end portion of the heel, the center of gravity position of the heel is shifted to the tip side by the weight of the balance means. This can be reliably prevented, and the position of the center of gravity can be shifted to the rear side as much as possible.
Further, the butt plug is attached to the rear end portion via the elastic member so as not to loosen, and it is possible to suitably prevent the balance means held by the butt plug from rattling.

  Further, according to the present invention, the balancing means comes into contact with the opposing surface at the bottom, and the opposing surface is elastically deformed, and the balancing means is suitably held in the axial direction (tip direction) of the heel by this contact. Therefore, the tail plug is screwed to the rear end portion and tightened, and at the same time, the balance means is held in contact with the bottom portion, so that the balance means can be reliably held in the axial direction. Thereby, it is possible to more suitably prevent the balance means from rattling at the time of throwing.

  Further, according to the present invention, since the peripheral portion of the balance means protrudes toward the inner peripheral surface rather than the head, the inner peripheral surface of the hollow portion securely contacts the peripheral portion with elasticity, and the balance means Is suitably held in the radial direction by the contact of the inner peripheral surface. Thereby, the balance means is firmly held on the inner peripheral surface, and it is possible to suitably prevent the balance means from rattling at the time of throwing.

Further, according to the present invention, the balance means is constituted by a plurality of annular members that can be combined in the axial direction of the flange, and the annular member arranged on the bottom side of the balance member is hollow by tightening by screwing the bottom plug. Since the inner peripheral surface and the bottom of the part are held in the two directions of the radial direction and the axial direction at the same time, they are arranged rearward in the axial direction of the collar than the annular member arranged on the bottom side. The annular member is held in the radial direction and the axial direction at the same time between the bottom side annular member and the bottom plug by the bottom side annular member. It is possible to suitably prevent rattling. Therefore, despite the fact that the balancing means is composed of a plurality of annular members, they are firmly held behind the rear end of the heel, and they are not stable when throwing. It can be surely prevented.
In addition, since a plurality of annular members can be selected and used, the balance can be adjusted suitably, which contributes to improvement in throwing operability and elimination of a feeling of weight.

  A hollow plug 11 and a weight 30 as a balance means can be inserted into the hollow portion 11 through the opening 11a. As will be described later, the hip plug 20 is screwed to the rear end 1a. As shown, these are arranged so as to be press-fitted into the hollow portion 11. Here, the inner peripheral surface 11b of the hollow portion 11 is provided with an inner diameter in which the peripheral portions 31b and 32b of the first and second annular members 31 and 32 described later of the weight 30 can be press-fitted. That is, as shown in FIG. 4A, the inner diameter D of the inner peripheral surface 11b of the hollow portion 11 is dimensioned to be smaller than the outer diameters D1, D2 of the first and second annular members 31, 32. It is set so that when the first and second annular members 31, 32 are inserted into the hollow portion 11, the inner peripheral surface 11b abuts on the peripheral portions 31b, 32b with elasticity. Yes.

  The bottom portion 11c of the hollow portion 11 is provided so as to face the front portions 31c and 32c of the first and second annular members 31 and 32 of the weight 30, and as will be described later, the bottom plug 20 is screwed. It is provided so that it can contact | abut to the front parts 31c and 32c of the 1st, 2nd annular members 31 and 32 which were pushed in and moved ahead. That is, as shown by a two-dot chain line in FIG. 4B, the bottom 11c (opposite surface at the bottom 11c) and the head 22 of the bottom plug 20 with the bottom end 20 screwed to the rear end 1a. The front-rear dimension L1 of the space formed between is set so as to be smaller than the thickness dimension L2 of the weight 30. In other words, the first and second annular members 31 and 32 are configured to abut against the opposing surfaces of the bottom portion 11c and to elastically deform them by tightening the bottom plug 20 by screwing.

  As shown in FIG. 2, a step 11d is provided between the rear end 1a and the bottom 11c for disposing an O-ring 23 as an elastic member. By providing this step 11d, the bottom 11c is comprised so that it may be located relatively back rather than the rear-end part 1a. That is, the bottom portion 11c is positioned relatively rearward of the rear end portion 1a and protrudes toward the first and second annular members 31 and 32, thereby, as described later, The bottom portion 11c surely comes into contact with the front portions 31c and 32c of the first and second annular members 31 and 32 that have been pushed forward by the screwing of the bottom plug 20 and moved forward.

The bottom plug 20 includes a shaft portion 21 and a head portion 22, and is made of a metal material such as aluminum or aluminum alloy, stainless steel, or a synthetic resin material such as nylon resin, ABS resin, It is made of a material such as polyacetal resin.
The end plug 20 can be screwed to the female screw 1b formed on the inner peripheral surface of the rear end portion 1a of the flange 1 by a male screw 21a formed on the front side of the shaft portion 21. It is configured to be detachable from 1a. A first annular member 31 is inserted and held around the holding surface 21 b on the rear side of the shaft portion 21, and the first annular member 31 is held via the held first annular member 31. Thus, the second annular member 32 is configured to be indirectly held by the shaft portion 21.
Further, the shaft portion 21 is formed with a circumferential groove 21c at a substantially central portion in the axial direction, and an O-ring 23 is attached to the circumferential groove 21c.
In the present embodiment, as will be described later, with the first and second annular members 31 and 32 held on the rear side of the shaft portion 21, the front portions 31 c and 32 c are the holding surfaces 21 b of the shaft portion 21. It is configured to project forward (protrude) from the front end (see FIGS. 5A and 5B).

As described above, the weight 30 is composed of the first and second annular members 31 and 32 that can be combined in the axial direction of the rod 1, and these are fitted in the front-rear direction as shown in FIG. In this state, it is held by the shaft portion 21 of the bottom plug 20 (see FIGS. 2 and 3).
The weight 30 is set so that the thickness L2 when fitted is larger than the front-rear dimension L1 of the space formed between the bottom 11c and the head 22 of the bottom plug 20 as described above. ing.
Further, the second annular member 32 arranged on the bottom 11c side of the front part 32c is directed toward the bottom 11c rather than the first annular member 31 as shown in FIG. While being configured to project, the peripheral portion 32 b is configured to project toward the inner peripheral surface 11 b rather than the first annular member 31.

  As shown in FIG. 4A, the first annular member 31 has an L-shaped cross section in the annular portion, and a cylindrical portion 31A and a flange portion 31B provided continuously to the cylindrical portion 31A. Consists of. The cylindrical portion 31A has a thickness L3 that is larger than the axial length L4 of the holding surface 21b of the shaft portion 21. Moreover, the outer diameter D1 of the collar part 31B is formed larger than the outer diameter D3 of the head part 22 of the bottom plug 20. As a result, when the first annular member 31 is inserted and held in the shaft portion 21 of the bottom plug 20, the front portion 31 c is more than the front end of the holding surface 21 b of the shaft portion 21 as shown in FIG. While projecting forward, the peripheral portion 31 b projects more radially than the peripheral portion 22 b of the head 22.

Further, as shown in FIG. 4A, the cylindrical portion 31 </ b> A has an inner diameter D <b> 1 ′ that is larger than an outer diameter D <b> 3 ′ on the rear portion side of the shaft portion 21, thereby the first annular member 31. Is rotatably held around the rear side of the shaft portion 21. In addition, the first annular member 31 has a rear surface 31e in contact with the front surface 22a of the head 22 so as to be slidable in the circumferential direction. Thus, when the first annular member 31 is inserted through the shaft portion 21, the two surfaces of the holding surface 21 b of the shaft portion 21 and the front surface 22 a of the head portion 22 are used in the radial direction and the axial direction of the bottom plug 20. It is supposed to be retained.
The first annular member 31 includes a holding portion 31C that holds the second annular member 32 by the circumferential surface 31c ′ of the cylindrical portion 31A and the front surface 31b ′ of the flange portion 31B, and the holding portion 31C. On the other hand, the second annular member 32 is detachably held.

  In the present embodiment, the first annular member 31 can be held by the bottom plug 20 alone. In this case, as described above, since the front portion 31c of the first annular member 31 protrudes forward from the front end of the holding surface 21b of the shaft portion 21, the bottom portion 11c is preferably in contact with the front portion 31c in the axial direction. Further, the peripheral portion 31b protrudes in the radial direction from the peripheral portion 22b of the head portion 22 so that the inner peripheral surface 11b abuts on this and holds in the radial direction. It has become.

  On the other hand, as for the 2nd annular member 32, the cross section of the annular part is exhibiting the square shape which can be fitted to the holding part 31C of the 1st annular member 31, The thickness dimension L5 is the 1st annular member. 31 is formed to be larger than the axial length L6 of the peripheral surface 31c ′. The second annular member 32 has an outer diameter D2 larger than the outer diameter D1 of the first annular member 31. Thus, when the second annular member 32 is fitted and held in the holding portion 31C of the first annular member 31, the front portion 32c is moved to the first annular shape as shown in FIG. In addition to projecting forward from the front portion 31 c of the member 31 (projecting), the peripheral portion 32 b projects (projects) in the radial direction from the peripheral portion 31 b of the first annular member 31.

As shown in FIG. 4A, the second annular member 32 has an inner diameter D2 ′ larger than the outer diameter D1 ″ of the cylindrical portion 31A of the first annular member 31. Thus, the second annular member 32 is rotatable around the holding portion 31C of the first annular member 31. Further, the second annular member 32 has a circumferential surface 31c ′ of the holding portion 31C and The two surfaces formed by the front surface 31b ′ are simultaneously held in the radial direction and the axial direction of the bottom plug 20.
As a result, when the second annular member 32 is held by the holding portion 31C of the first annular member 31 and the tail plug 20 is screwed to the rear end portion 1a as described later, as shown in FIG. 5A. Further, the bottom portion 11c of the hollow portion 11 abuts elastically against the front portion 32c of the second annular member 32 protruding forward from the front portion 31c of the first annular member 31, and the first annular member The inner peripheral surface 11b of the hollow portion 11 abuts elastically against the peripheral portion 32b of the second annular member 32 protruding in the radial direction from the peripheral portion 31b of 31.

In the present embodiment, as shown in FIG. 5B, the frictional resistance P <b> 1 generated between the opposed surfaces of the bottom plug 20 and the weight 30 is the inner peripheral surface of the weight 30 and the hollow portion 11. 11b is set to be smaller than the frictional resistance force P2 generated by press fitting (P1 <P2).
Specifically, between the holding surface 21b of the shaft portion 21 of the bottom plug 20 and the front surface 22a of the head portion 22, and the inner surface 31d and the rear surface 31e of the first annular member 31 (hereinafter referred to as the sliding contact surface portion A). Is set to be smaller than the frictional resistance P2 generated between the peripheral portion 32b of the second annular member 32 and the inner peripheral surface 11b (hereinafter referred to as the sliding contact surface portion B). Has been.

That is, in the sliding contact surface portion A, the bottom plug 20 is easily slipped in the circumferential direction with respect to the first annular member 31, and the bottom plug 20 is easily rotated with respect to the first annular member 31. .
On the other hand, in the sliding surface portion B, the second annular member 32 is difficult to slide in the circumferential direction with respect to the inner peripheral surface 11b of the hollow portion 11, and the second annular member 32 rotates with respect to the inner peripheral surface 11b. It is difficult to move.

  In addition, when the 1st annular member 31 is independently mounted | worn with the bottom plug 20, the frictional-resistance force P1 is the friction which arises between the peripheral part 31b of the 1st annular member 31, and the internal peripheral surface 11b. It is set so as to be smaller than the resistance force P2 ′ (not shown) (P1 <P2 ′).

Next, the operation at the time of attaching and removing the bottom plug 20 will be described.
First, the weight 30 is attached to the butt plug 20. When both the first and second annular members 31, 32 are attached as the weight 30, the first and second annular members 31, 32 are fitted together, and then the shaft portion 21 is attached thereto. It may be inserted, or may be inserted and held in order through the first and second annular members 31 and 32.

  When the first and second annular members 31 and 32 are held on the shaft portion 21, as shown in FIG. 5B, the front side of the shaft portion 21 is inserted into the hollow portion 11, and the male screw 21a is inserted. Screwed onto the female screw 1b of the rear end 1a. At this time, the second annular member 32 is fitted to the first annular member 31 and held on the shaft portion 21, and the outer diameter D <b> 2 of the second annular member 32 is the inner diameter of the hollow portion 11. Since it is formed larger than D, when the second annular member 32 is inserted into the hollow portion 11, the inner peripheral surface 11 b of the hollow portion 11 is pushed and expanded by the peripheral portion 32 c of the second annular member 32. It abuts against this with elasticity. Thus, the second annular member 32 is press-fitted and held in a state in which it is difficult to rotate in the circumferential direction of the inner peripheral surface 11b.

  On the other hand, in the sliding contact surface portion A, the frictional resistance force P1 is smaller than the frictional resistance force P2 in the sliding contact surface portion B, and the tail plug 20 is easy to rotate with respect to the first annular member 31. When the turning operation for tightening the butt plug 20 is performed, the butt plug 20 is smoothly rotated in the circumferential direction with respect to the second annular member 32 (first annular member 31) that is press-fitted and held. Become. Therefore, the tightening operation of the bottom plug 20 can be easily performed.

  Thereafter, when the butt plug 20 is further tightened, the butt plug 20 is moved to the front side in the axial direction of the collar 1 by screwing, and at this time, the weight 30 held by the butt plug 20 is also press-fitted and held. In this state, the butt plug 20 is pushed by the screwing of the butt plug 20 and moves together with the butt plug 20 without rotating in the circumferential direction by the frictional resistance P2 at the sliding contact surface portion B.

Therefore, the tightening operation force required when tightening the bottom plug 20 is sufficient to push the second annular member 32 to the front side in the axial direction. Therefore, the peripheral portion of the second annular member 32 is sufficient. The force received by 32b can be minimized.
As a result, the bottom plug 20 can be tightened smoothly, the attachment and removal operations of the first and second annular members 31 and 32 are simplified, and a fishing rod excellent in operability can be obtained.

  On the other hand, the bottom portion 11c of the hollow portion 11 is provided opposite to the front portion 32c of the second annular member 32, and is pushed in by screwing of the bottom plug 20 and moved to the front side in the axial direction. Since it can come into contact with the front part 32 c of the annular member 32, when the bottom plug 20 is screwed and tightened to the rear end part 1 a, the bottom part 11 c of the hollow part 11 becomes the front part of the second annular member 32. The second annular member 32 is suitably held in the axial direction by the contact of the bottom portion 11c.

  Therefore, the weight 30 is simultaneously held in the two directions of the radial direction and the axial direction by the inner peripheral surface 11b and the bottom portion 11c of the hollow portion 11 by tightening the bottom plug 20 by screwing. It is press-fitted between the face 11b and the bottom part 11c and the bottom plug 20 and sandwiched.

  Further, when the butt plug 20 is screwed to the rear end portion 1a and tightened, an O-ring 23 is disposed in a space (step 11d) between the rear end portion 1a and the bottom portion 11c. It will be attached to the rear end 1a via the O-ring 23 in a state where it is difficult to loosen. As a result, reliable attachment of the bottom plug 20 is realized.

  In addition, by forming a space in which the O-ring 23 is disposed, the bottom portion 11c is positioned rearward in the axial direction from the rear end portion 1a by at least the space, thereby the rear end portion. The weight 30 will be arrange | positioned at the back of an axial direction rather than 1a.

Even when the first annular member 31 is attached to the bottom plug 20 alone, by tightening the bottom plug 20 by screwing, the inner peripheral surface 11b and the bottom 11c of the hollow portion 11 and the bottom plug 20 are secured. The first annular member 31 can be press-fitted between the two.
That is, the first annular member 31 has an L-shaped cross section of the annular portion, the front portion 31c projects forward from the front end of the holding surface 21b of the shaft portion 21, and the peripheral portion 31b is the head portion. 22 protrudes toward the inner peripheral surface 11b of the hollow portion 11 rather than the peripheral portion 22b of the inner portion 22. Therefore, in the hollow portion 11, the bottom portion 11c elastically contacts the front portion 31c, and the inner peripheral surface 11b is the peripheral portion. It abuts elastically on 31b and is held simultaneously in the axial direction and the radial direction.

  Moreover, what is necessary is just to rotate in the direction which loosens the bottom plug 20 when removing the bottom plug 20. Here, when the butt plug 20 is rotated in the loosening direction, the butt plug 20 moves toward the opening portion 11a of the hollow portion 11. However, the inner peripheral surface 11b of the hollow portion 11 has a second shape. Since the elastic member is in contact with the peripheral portion 32 b of the annular member 32, the second annular member 32 and the first annular member 31 remain in the hollow portion 11 even if the bottom plug 20 is loosened. For this reason, when removing the butt plug 20, no operating force is required to move the first and second annular members 31, 32, and the butt plug 20 is easily loosened from the hollow portion 11. Can be removed.

  The first and second annular members 31 and 32 remaining inside the hollow portion 11 can be easily pulled out by putting a finger or the like inside the hollow portion 11 and hooking it. That is, since the first and second annular members 31 and 32 are retained and retained inside the hollow portion 11 until the weight 30 is pulled out, the weight 30 is replaced during actual fishing or the like. In addition, it is possible to suitably prevent a problem that the weight 30 is unexpectedly dropped from the hollow portion 11 and lost.

  According to the fishing rod of the present embodiment described above, the bottomed cylindrical grip portion 10 attached to the outer periphery of the rear end portion 1a is made of a flexible member, extends to the rear of the rear end portion 1a, and has a bottom plug 20. And the hollow portion 11 in which the weight 30 is disposed. The hollow portion 11 has an inner peripheral surface 11b that can be press-fitted into the peripheral portions 31b and 32b of the first and second annular members 31 and 32. Since the bottom plug 20 holding the first and second annular members 31 and 32 is inserted into the hollow portion 11 when the bottom plug 20 is screwed, the inside of the hollow portion 11 is provided. The peripheral surface 11b elastically contacts the peripheral portions 31b and 32b, and the first and second annular members 31 and 32 are suitably held in the radial direction by the contact of the inner peripheral surface 11b.

  On the other hand, the bottom portion 11c of the hollow portion 11 is provided to face the front portion 32c of the second annular member 32, and is pushed by the screwing of the bottom plug 20 and moved forward. Since it can come into contact with the front portion 32c, when the bottom plug 20 inserted into the hollow portion 11 is screwed to the rear end portion 1a of the flange 1, the bottom portion 11c of the hollow portion 11 is mainly the second annular member. The second annular member 32 (first annular member 31) is suitably held in the axial direction (tip direction) of the collar 1 by the contact of the bottom 11c. The

Therefore, the first and second annular members 31 and 32 (weight 30) are diametrically and axially separated by the inner peripheral surface 11b and the bottom portion 11c of the hollow portion 11 by tightening the bottom plug 20 by screwing. It will be hold | maintained simultaneously in a direction, and will be press-fitted between these inner peripheral surfaces 11b and the bottom part 11c, and the butt plug 20, and will be clamped.
For this reason, the weight 30 can be firmly held behind the rear end portion 1a of the rod 1, and it is possible to suitably prevent the weight 30 from rattling at the time of throwing.
In addition, since the weight 30 is held behind the rear end portion 1a, the inner diameter of the heel is limited as in the conventional case, like the one inserted into the rear portion inside the heel. Absent. Therefore, the weight 30 can be formed larger in the radial direction than the outer diameter of the rear end portion 1a of the rod 1, and the position of the center of gravity can be shifted to the rear side as much as possible. Further, since the weight 30 is held behind the rear end portion 1a, the center of gravity position of the heel 1 does not shift to the tip side due to the weight of the weight 30, and the center of gravity position is moved as far back as possible. Can be shifted to the side.

  Further, since the O-ring 23 is disposed between the bottom portion 11c and the rear end portion 1a, the bottom plug 20 is attached to the rear end portion 1a through the O-ring 23 so as not to be loosened. As a result, the weight 30 held by the bottom plug 20 can be suitably prevented from rattling.

Further, since the second annular member 32 of the weight 30 is configured to elastically deform the opposing surface of the bottom portion 11c by tightening the bottom plug 20 by screwing, the bottom plug 20 is screwed to the rear end portion 1a. When tightened, the second annular member 32 comes into contact with the opposing surface of the bottom portion 11c and the opposing surface is elastically deformed. Direction).
Accordingly, since the second annular member 32 is held in contact with the bottom portion 11c at the same time as the bottom plug 20 is screwed to the rear end portion 1a, the second annular member 32 is securely attached to the bottom portion 11c. It can be made to contact | abut, and it can prevent more appropriately the weight 30 containing the 2nd annular member 32 at the time of throwing.

Further, the bottom plug 20 includes the shaft portion 21 and the head portion 22, and the weight 30 has the peripheral portions 31 b and 32 b projecting from the head portion 22 toward the inner peripheral surface 11 b, so that the bottom plug 20 is screwed. When the end plug 20 holding the weight 30 is inserted into the hollow portion 11 when worn, the inner peripheral surface 11b of the hollow portion 11 is extended with respect to the peripheral portions 31b and 32b protruding from the head portion 22 toward the inner peripheral surface 11b. The second annular member 32 is suitably held in the radial direction by the contact of the inner peripheral surface 11b.
Therefore, the weight 30 can be firmly held on the inner peripheral surface 11b, and it is possible to suitably prevent the weight 30 from rattling when throwing.

The weight 30 is composed of first and second annular members 31 and 32 that can be combined in the axial direction of the rod 1, and the second annular member 32 disposed on the bottom 11 c side of the weight 30 is the front thereof. Since the portion 32c protrudes toward the bottom portion 11c from the first annular member 31, and the peripheral portion 32b protrudes toward the inner peripheral surface 11b from the first annular member 31, the bottom portion 11c. The second annular member 32 disposed on the side has the inner peripheral surface 11b of the hollow portion 11 in contact with the peripheral portion 32b with elasticity and is suitably held in the radial direction, and the bottom portion 11c at the front portion 32c. It will contact | abut with elasticity and will be hold | maintained suitably in an axial direction.
Therefore, the first annular member 31 disposed behind the second annular member 32 disposed on the bottom portion 11c side causes the second annular member 32 to connect the second annular member 32 and the bottom plug 20 with each other. It is held at the same time in the two directions of the radial direction and the axial direction between the first and second annular members 31, 32, thereby suitably preventing the first and second annular members 31, 32 from rattling.
Therefore, even though the weight 30 is composed of a plurality of annular members 31 and 32, the weight 30 is firmly held behind the rear end 1a of the rod 1, and these are loose when throwing. It can be surely prevented from sticking.
Further, the weight 30 can be used with both the first and second annular members 31 and 32 attached to the bottom plug 20, and only the first annular member 31 is attached to the bottom plug 20. Therefore, by selecting these, it becomes possible to suitably adjust the balance, which contributes to improvement in throwing operability and elimination of a feeling of weight.

  Further, the frictional resistance force P1 generated on the sliding contact surface portion A between the bottom plug 20 and the weight 30 is smaller than the frictional resistance force P2 generated on the inner peripheral surface 11b and the sliding contact surface portion B of the weight 30 and the hollow portion 11. In the sliding contact surface portion A, the tail plug 20 is easily slipped and rotated in the circumferential direction with respect to the first annular member 31, while the sliding contact surface portion B has the hollow portion 11. The second annular member 32 is difficult to slide in the circumferential direction with respect to the inner peripheral surface 11b, and the second annular member 32 is difficult to rotate with respect to the inner peripheral surface 11b. Therefore, when the turning operation for tightening the bottom plug 20 is performed, the bottom plug 20 is smoothly rotated in the circumferential direction with respect to the second annular member 32 (first annular member 31) that is press-fitted and held. It becomes. Therefore, the tightening operation of the butt plug 20 can be easily performed, and the attachment / detachment operation of the butt plug 20 is facilitated.

  Here, the first and second annular members 31 and 32 have at least one of a concave portion, a convex portion, a concave groove along the axial direction, and a convex strip along the axial direction with respect to the peripheral portions 31b and 32b. One resistance force generating means may be provided, and the peripheral portions 31b and 32b may be roughened by this resistance force generating means.

  FIG. 6A shows an example in which ridges 310 and 320 along the axial direction are provided as resistance force generating means on the peripheral portions 31b and 32b of the first and second annular members 31 and 32, respectively. By providing such ridges 310 and 320, the first and second annular members 31 and 32 are suitable for the inner peripheral surface 11b of the hollow portion 11 (see FIGS. 5A and 5B, the same applies hereinafter). Thus, the bottom plug 20 is easily rotated with respect to the first annular member 31 (second annular member 32). Thus, by performing a turning operation for tightening the butt plug 20, the butt plug 20 is smoothly rotated in the circumferential direction with respect to the press-fitted and held first annular member 31 (second annular member 32). Therefore, the tightening operation and the detaching operation of the bottom plug 20 can be easily performed. Therefore, a fishing rod excellent in operability can be obtained. Since the protrusions 310 and 320 are along the axial direction, the butt plug 20 is pushed in by screwing the butt plug 20 while being press-fitted and held so as not to rotate in the circumferential direction of the inner peripheral surface 11b. And move appropriately. In addition, by changing the formation interval in the circumferential direction of the ridges 310 and 320 as appropriate, the frictional resistance generated between the inner circumferential surface 11b can be adjusted by setting the number of ridges 310 and 320 formed. it can.

FIG. 6B shows an example in which convex portions 311 and 321 are provided as resistance force generating means on the peripheral portions 31 b and 32 b of the first and second annular members 31 and 32. Also by providing such convex portions 311 and 321, the first and second annular members 31 and 32 are suitably press-fitted and held on the inner peripheral surface 11 b of the hollow portion 11.
In addition, the frictional resistance force generated between the inner peripheral surface 11b can be adjusted by appropriately setting the number of protrusions 311 and 321 formed.

FIG. 6C shows a modified example shown later, in which a weight 30 ′ composed of first, second, and third annular members 33, 34, 35 is used. The example which provided the protruding item | line 330,340,350 along an axial direction in 34b, 35b is shown. In this example, the formation intervals in the circumferential direction of the ridges 330, 340, and 350 are made different between the first, second, and third annular members 33, 34, and 35, respectively, so that the ridges 330, 340, and 350 are formed. The number is different. Even when the ridges 330, 340, and 350 are provided for the weight 30 ′ composed of the first, second, and third annular members 33, 34, and 35, these are the inner periphery of the hollow portion 11. The surface 11b is preferably press-fitted and held.
In the above-described example, the protrusions 310 and the like are provided on the weights 30 and 30 ′, but the inner peripheral surface 11 b of the hollow portion 11 may be a rough surface.

  Further, a smooth sheet member (not shown), for example, a film or sheet made of Teflon (registered trademark), a silicone sheet, or the like is slidably contacting the surface portion A (at least one of the opposing surfaces of the bottom plug 20 and the first annular member 31). The frictional resistance force P1 generated at the sliding contact surface portion A may be preferably smaller than the frictional resistance force P2 generated at the sliding contact surface portion B.

  7 (a) to 7 (c) show modifications of the present invention. This modification is different from the O-ring 23 described above in that a washer-like elastic member 23 ′ is attached to the circumferential groove 21c of the bottom plug 20, and a space (stage) where the elastic member 23 ′ is disposed. Part) 11d 'is formed between the rear end part 1a and the bottom part 11c.

As shown in FIGS. 7B and 7C, the elastic member 23 ′ is attached to the circumferential groove 21 c of the bottom plug 20, and its rear surface is the front part of the first and second annular members 31 and 32. The first and second annular members 31 and 32 are configured to function as stoppers for preventing the first and second annular members 31 and 32 from falling off.
That is, as shown in FIG. 7C, when an operation of loosening the bottom plug 20 in the removing direction is performed, the first and second annular members 31 and 32 are connected to the rear plug as the rear plug 20 moves backward. The elastic member 23 ′ comes into contact with the front portions 31 c, 32 c of the first and second annular members 31, 32, and they are preferably dropped from the bottom plug 20. Is prevented.

  With this configuration, the first and second annular members 31 and 32 can be removed from the inside of the hollow portion 11 simultaneously with the removal of the bottom plug 20, and the first and second annular members 31 and 32 can be removed by the elastic member 23 ′. It is possible to suitably prevent the second annular members 31 and 32 from falling off the bottom plug 20. Accordingly, it is possible to prevent the first and second annular members 31 and 32 from being lost during the replacement operation.

FIGS. 8A and 8B are diagrams showing other modified examples, FIG. 8A is an explanatory diagram for explaining the configuration of the weight 30 ′, and FIG. 8B is a cross-sectional view of the state in which the weight 30 ′ is mounted. .
As shown in these drawings, the weight 30 ′ includes first, second, and third annular members 33, 34, 35 that can be combined in the axial direction of the rod 1, as shown in FIG. 8B. In addition, the shaft portion 21 of the bottom plug 20 is held in a state in which these are fitted in the front-rear direction.
The weight 30 ′ has a thickness dimension when fitted to each other in the same manner as described above, the front-rear dimension L 1 of the space formed between the bottom portion 11 c and the head portion 22 of the bottom plug 20 (see FIG. 4B). It is set to be larger. The first annular member 33 is held by the shaft portion 21, and the second annular member 34 is held by the shaft portion 21 via the first annular member 33. The second annular member 34 holds the third annular member 35.

Each of the first and second annular members 33 and 34 has an L-shaped cross section of the annular portion, and includes cylindrical portions 33A and 34A and flange portions 33B and 34B. In the first annular member 33, the peripheral surface 33c ′ of the cylindrical portion 33A and the front surface 33b ′ of the flange portion 33B constitute a holding portion 33C that holds the second annular member 34, and the holding portion 33C Thus, the second annular member 34 is detachably held. Further, in the second annular member 34, the peripheral surface 34c ′ of the cylindrical portion 34A and the front surface 34b ′ of the flange portion 34B constitute a holding portion 34C that holds the third annular member 35, and this holding portion 34C. In contrast, the third annular member 35 is detachably held.
The third annular member 35 has a quadrangular shape in which the cross-section of the annular portion can be fitted into the holding portion 34 </ b> C of the second annular member 34. In addition, if the 2nd annular member 34 is hold | maintained between the 1st annular member 33 and the 3rd annular member 35, the thing formed in the flat disk shape, for example will be used. Also good.

The first annular member 33 is configured such that the peripheral portion 33b projects in a radial direction from the peripheral portion 22b of the head portion 22, and the peripheral portion 34b of the second annular member 34 is It is comprised so that it may project over radial direction rather than the surrounding part 33b. Further, the peripheral portion 35b of the third annular member 35 is configured to protrude in the radial direction from the peripheral portion 34b.
In addition, the front portion 33 c of the first annular member 33 is configured to protrude from the front end of the holding surface 21 b of the shaft portion 21 toward the bottom portion 11 c, and the front portion 34 c of the second annular member 34. However, it is comprised so that it may protrude to the bottom part 11c side rather than this front part 33c. Further, the front portion 35c of the third annular member 35 is configured to protrude toward the bottom portion 11c side from the front portion 34c.
That is, the third annular member 35 disposed on the bottom 11c side of the hollow portion 11 is configured so that the peripheral portion 35b protrudes most of them toward the inner peripheral surface 11b, and the The front portion 35c is configured to protrude most toward the bottom portion 11c.

  In this example as well, the first annular member 33 can be held by the bottom plug 20 alone, or the first annular member 33 and the second annular member 34 can be fitted to the bottom plug 20. It can also be held.

Further, as shown in FIG. 8B, the frictional resistance P1 ″ generated between the opposing surfaces of the bottom plug 20 and the weight 30 ′ is the weight 30 ′ and the inner peripheral surface 11b of the hollow portion 11. Is set so as to be smaller than the frictional resistance force P2 ″ generated between (P1 ″ <P2 ″).
Specifically, between the holding surface 21b of the shaft portion 21 of the bottom plug 20 and the front surface 22a of the head portion 22 and the inner surface 33d and the rear surface 33e of the first annular member 33 (hereinafter referred to as a sliding contact surface portion A ″). ) Is smaller than the frictional resistance P2 ″ generated between the peripheral portion 35b of the third annular member 35 and the inner peripheral surface 11b (hereinafter referred to as the sliding contact surface portion B ″). It is set to be.

That is, in the sliding contact surface portion A ″, the bottom plug 20 is easily slipped in the circumferential direction with respect to the first annular member 33, and the bottom plug 20 is easily rotated with respect to the first annular member 33. Yes.
On the other hand, in the slidable contact surface portion B ″, the third annular member 35 is difficult to slide in the circumferential direction with respect to the inner peripheral surface 11b of the hollow portion 11, and the third annular member 35 is not easily slipped in the inner peripheral surface 11b. It is difficult to turn.

By setting it as such a structure, the 3rd annular member 35 will be press-fitted and hold | maintained in the state which is hard to rotate to the circumferential direction of the internal peripheral surface 11b.
On the other hand, in the sliding contact surface portion A ″, the frictional resistance force P1 ″ is smaller than the frictional resistance force P2 ″ in the sliding contact surface portion B ″, and the tail plug 20 is easy to rotate with respect to the first annular member 33. Therefore, when a turning operation for tightening the butt plug 20 is performed, the butt plug 20 moves in the circumferential direction with respect to the third annular member 35 (first and second annular members 33, 34) that is press-fitted and held. Will be smoothly rotated. Therefore, the tightening operation of the bottom plug 20 can be easily performed.

  Thereafter, when the butt plug 20 is further tightened, the butt plug 20 is moved to the front side in the axial direction of the flange 1 by screwing, and at this time, the weight 30 ′ held by the butt plug 20 is also press-fitted and held. While being held in this state and without being rotated in the circumferential direction by the frictional resistance P2 ″ at the sliding contact surface portion B ″, it is pushed in by screwing of the bottom plug 20 and moves together with the bottom plug 20.

Therefore, the tightening operation force necessary for tightening the bottom plug 20 is sufficient to push the third annular member 35 toward the front side in the axial direction. Therefore, the peripheral portion of the third annular member 35 is sufficient. The force received by 35b can be minimized.
As a result, the end plug 20 can be smoothly tightened, and the first and second and third annular members 33, 34 and 35 can be easily attached and detached, and a fishing rod excellent in operability can be obtained. It is done.

On the other hand, the bottom portion 11c of the hollow portion 11 is provided to face the front portion 35c of the third annular member 35, and is pushed in by screwing of the bottom plug 20 and moved to the front side in the axial direction. Since it can come into contact with the front part 35 c of the annular member 35, when the bottom plug 20 is screwed and tightened to the rear end part 1 a, the bottom part 11 c of the hollow part 11 becomes the front part of the third annular member 35. The third annular member 35 is suitably held in the axial direction by the contact of the bottom portion 11c.
Therefore, the second annular member 34 and the first annular member 33 disposed behind the third annular member 35 in the axial direction of the bag are replaced by the third annular member 35 by the third annular member 35. 35 and the bottom plug 20 are held simultaneously in two directions, ie, in the radial direction and in the axial direction, thereby suitably preventing the first to third annular members 31 to 35 from rattling. can do.

As a result, the weight 30 ′ is simultaneously held in the two directions of the radial direction and the axial direction by the inner peripheral surface 11 b and the bottom portion 11 c of the hollow portion 11 by tightening the bottom plug 20 by screwing. The inner peripheral surface 11b and the bottom portion 11c are press-fitted between the bottom plug 20 and sandwiched.
Therefore, the weight 30 ′ can be firmly held behind the rear end portion 1a of the kite 1, and it is possible to suitably prevent the weight 30 ′ from rattling when throwing.
Further, since the weight 30 'is composed of the first to third annular members 33 to 35, the center of gravity position is shifted to the rear side as much as possible by appropriately setting these weights (specific gravity). Therefore, it is possible to obtain a feeling of operation as expected during a throwing operation. Moreover, it contributes to eliminating a feeling of weight in a fishing state.

  Further, as shown in FIG. 9A, the inner diameter D of the inner peripheral surface 11b ′ of the hollow portion 11 is narrowed from the rear side (opening 11a side) toward the front side (bottom 11c ′ side). In this manner, it may be formed in a tapered shape (so as to have an inner diameter D ′ smaller than the inner diameter D), and may be formed in a tapered shape so that the opposed surface of the bottom portion 11c ′ is directed toward the rear side. That is, in this example, the inner peripheral surface 11b ′ and the bottom portion 11c ′ of the hollow portion 11 are inclined so that they are in contact with the weight 30 ″ in the circumferential direction and the axial direction, As a result, the weight 30 ″ is held in two directions, the circumferential direction and the axial direction. In this case, the first and second annular members 31 ′ and 32 ′ of the weight 30 ″ are equivalent to the outer diameter D3 of the head portion 22 of the bottom plug 20 without making the outer diameters different as described above. Can be formed.

  In such a configuration, when the bottom plug 20 is screwed and tightened to the rear end portion 1a, the inner peripheral surface 11b ′ and the bottom portion 11c ′ of the hollow portion 11 become a weight 30 ″ as shown in FIG. 9B. Each of them abuts with elasticity, and the weight 30 ″ is held in the hollow portion 11 without rattling.
