Description

  The present invention relates to a lure used for fishing, and more particularly to a lure having a structure in which a weight inside a hollow moves.

Conventionally, a type of lure called a plug has a weight that can be moved inside a main body that looks and looks like a small fish (see Patent Document 1), and improves the flying posture during casting. While enabling long-distance casting, it was possible to stabilize the center of gravity of the lure during reeling. In this type of technology, there is a configuration in which the weight can be moved by a weight that rolls within the lure body, and the position of the weight is determined when the weight is fitted into a recess provided at a predetermined position. (Patent Document 1), and there are those that are magnetized at predetermined positions by magnets (Patent Documents 2 and 3).
Japanese Patent Laid-Open No. 10-327708 (FIGS. 2, 4 to 7) JP-A-11-113449 Japanese Patent No. 3017727 Japanese Patent No. 3629402 (page 2-4, FIG. 3 to FIG. 6) Japanese Patent Laid-Open No. 11-346601 (page 3-5, FIGS. 1 to 8) JP 2001-120115 A JP 2003-250387 A

  Among the above-described conventional techniques, in the configuration in which the weight is fitted into the recess, the weight is not fixedly positioned on the luer body, and when the lure body vibrates violently in water, The position of the weight may change slightly, and a slight collision noise may be generated due to the weight colliding with the inner wall surface of the lure body. Sometimes it would be unnatural. Therefore, the applicant of the present application has invented a gravity center moving member having a structure in which a stopper made of a steel piece is provided at the front end of the shaft and a weight having a high specific gravity substance as a main body portion is inserted through the shaft (see Patent Document 4).

  On the other hand, in the configuration in which the weight is magnetized by the magnet, the magnet is arranged at a position where the weight should be stopped. However, when the weight is spherical, the magnetizing force by the magnet acts strongly. In addition, the weight must have a composition in which materials that can be magnetically admixed are mixed, and a strong magnetic adhesion force cannot be obtained. Furthermore, since the location where the spherical weight collides with the magnet becomes the same, when using a ferrite magnet, a relatively fragile magnet may be damaged, and a buffer member is provided on the magnet surface to eliminate this. Although there is a construction technique (refer to Patent Document 5), as a result, a decrease in weight magnetic adhesion force by a magnet is caused. In view of this, the applicant of the present application, in the technique disclosed in the above-mentioned Patent Document 4, has a configuration in which a magnet piece is provided in the main body portion of the weight, and the entire surface of the magnet piece comes into contact with the stopper of the steel piece. Since the magnet piece and the steel piece abut on the entire surface in this way, the impact caused by the weight is distributed over the entire surface, and the magnet piece is magnetically attached over a wide area. The magnetizing force was strong.

  However, in the technique described in the above-mentioned Patent Document 4, when the magnet piece is provided integrally with the weight, if the shaft is made of a general metal, the weight magnet piece is also magnetically attached to the shaft. Therefore, stainless steel or phosphor bronze has been used as the material of the shaft. For this reason, the shaft cannot be made of a general-purpose product and has to be expensive.

  Further, the weight and the stopper are loosely fitted to the shaft at the same time, and only the stopper is magnetized and stopped at a predetermined position (see Patent Document 6), or the weight is restricted by a deformable ring ( Although there is Patent Document 7), neither of the configurations is a configuration in which a movable weight can be fixedly stopped at a predetermined position.

  The present invention has been made in view of the above-mentioned points, and the object of the present invention is to eliminate the occurrence of a collision sound due to an impact with the lure body in the state of movement and stop of the weight, and by using an inexpensive material. It is to provide a lure capable of moving the center of gravity.

  Therefore, the present invention provides a lure in which a shaft is disposed along the longitudinal direction of the hollow interior formed in the lure body, the weight is inserted through the shaft, and moves along the shaft. The gist of the present invention is a lure characterized in that an abutting portion that abuts against the surface of the weight at an arbitrary position within the range of movement of the weight is provided inside the lure body.

  With the above configuration, the weight moving along the shaft is locked to the contact portion by the contact with the weight at the position where the contact portion is provided, and the pressing force uses the repulsive force due to the elastic deformation of the shaft. And the movement is stopped. Therefore, a contact portion is provided at a position that should be an optimum weight balance for the lure in water, and a continuous shaft is arranged on the rear end side (tail side) from that position, so that the weight can be reduced at the rear end ( The weight can be moved to the vicinity of the tail portion, and the weight can be stopped at a position where the optimum weight balance is obtained after casting. Since the shaft always presses the weight in a certain direction, no play is generated between the weight and the shaft, and no collision sound or the like is generated even when the lure vibrates.

  Further, the present invention provides a lure in which a shaft is disposed along a longitudinal direction of a hollow interior formed in a lure body, and a weight that is penetrated by the shaft and moves along the shaft is incorporated in the lure. Is a shaft having a stopper at its longitudinal end, and a lure characterized in that a contact portion that contacts the surface of the weight when the weight moves to the stopper is provided inside the lure body. It is said.

  According to the above configuration, the movement of the weight is stopped by the stopper, and in this state, the pressure due to the repulsion of the elastic deformation of the shaft is applied to this weight, so the position of the weight whose movement is restricted by the stopper is By restricting the position of the stopper so as to be a position suitable for the optimum weight balance in the entire lure, the weight can be kept stopped at the optimum position.

  In each of the above inventions, the structure of the abutting portion includes an arc-shaped projecting portion formed by projecting a portion where the weight surface abuts in an arc shape, and a part of the arc-shaped projecting portion abuts on the weight surface. It can comprise so that it may become a contact part which suppresses a movement. With such a configuration, when the weight moving along the shaft approaches the contact portion, the arcuate protrusion that is a part of the contact portion contacts the surface of the weight. Then, when the arcuate protrusion comes into contact with the weight surface, the weight can be restrained in a predetermined direction.

  In the above configuration, the weight is formed on the surface with an engagement recess into which a part of the arc-shaped protrusion can be engaged, and a part of the arc-shaped protrusion is formed in the engagement recess of the weight. When engaged, this arcuate protrusion can be configured to lock the weight in a predetermined direction. With such a configuration, the position of the portion of the arcuate protruding portion engaged with the engagement recess of the weight is limited, and the movement of the weight can be reliably stopped. And even if a part of the arcuate protrusion is engaged in the engagement recess, the weight is pressed by the repulsion of the elastic deformation of the shaft, so that the occurrence of a gap with the shaft etc. is prevented and the lure vibrates Even so, it is possible to prevent a collision sound or the like from being generated.

  Furthermore, the present invention provides a lure in which a shaft is disposed along the longitudinal direction of the hollow interior formed in the lure body, and a weight that penetrates the shaft and moves along the shaft is incorporated in the lure. Is a shaft in which stoppers are respectively disposed at the longitudinal front and rear ends of the luer body, and an arc-shaped projecting portion is provided in the lure body in the vicinity of the front end of the shaft so as to project in an arc shape. The gist of the present invention is a lure characterized in that, when coming into contact with the surface of the weight, the weight is held between the shaft and the arcuate protrusion.

  With the above configuration, the weight can move along the shaft disposed inside the lure body, but its movement is limited by stoppers provided in the vicinity of the longitudinal front and rear ends. The weight in the middle of reaching the stopper can be brought into contact with the arcuate protrusion of the contact portion. Therefore, firstly, the moving speed of the moving weight is decelerated by the arc-shaped protrusion immediately before the stopper, and secondly, the weight stopped by the stopper is held between the shaft and the arc-shaped protrusion. Therefore, the stop state is maintained. As a result, the position of the stopped weight does not fluctuate due to the vibration of the lure, and it is possible to prevent the occurrence of a collision sound or the like with the inner wall or shaft of the lure body.

  In the invention having the arc-shaped projecting portion, the arc-shaped projecting portion may be configured such that all or part of the arc-shaped projecting portion projects in an arc shape. With this configuration, as the weight approaches the stopper, the pressing force can be obtained by utilizing the repulsive force generated by the elastic deformation of the shaft that is engaged with the protruding portion of the arc-shaped protruding portion and is inserted through the weight. When the weight is formed in a cylindrical shape and the axial direction thereof is matched with the moving direction, the surface of the abutting portion comes into contact with the circular surface in the tangential direction, and the width of the abutting portion When any part of the direction is in contact with the circular surface, the weight can be pressed.

  The weight in each of the above inventions is a weight formed in a substantially cylindrical shape, and the contact portion may be a contact portion that abuts at two locations on the outer peripheral edge of the weight of the cross section of the cross section. it can. With such a configuration, since the columnar through hole is provided in the axial direction of the substantially cylindrical weight, the contact portion of the weight with the shaft can be configured to be long, and substantially along the longitudinal direction of the shaft. It becomes easy to match the direction of the cylindrical weight. Therefore, the position where the weight moves can be predicted, and the contact portion or the stopper can be appropriately disposed at a desired position based on the prediction.

  The weight in the invention is a weight composed of a weight main body formed in a desired shape and a through hole formed by eccentrically penetrating the weight main body, and the shaft is inserted into the through hole. In some cases, the weight may be maintained in a predetermined posture. With such a configuration, the weight is supported by the shaft inserted through the through hole, but the weight itself selects the posture to be supported so that the position of the center of gravity is lower than the through hole. Therefore, the weight posture is stable because it is determined in a constant state. And since the posture of the weight is stabilized, the place pressed by the repulsion of the elastic deformation of the shaft is constant, especially in the case of a contact part having an arcuate protrusion, the contact part by the arcuate protrusion is constant. The pressing state due to the repulsion of the elastic deformation of the shaft can be stabilized.

  Furthermore, the weight according to the present invention is composed of a weight body formed in a desired shape and a plurality of through holes penetrating at different positions of the weight body, and is inserted through the plurality of through holes. There can be multiple shafts. According to the above configuration, the posture of the weight is stabilized by the plurality of shafts inserted through the plurality of through holes, and only a certain portion of the weight can be pressed by repulsion of the elastic deformation of the shaft.

  The shaft in each of the above inventions can be provided so as to be inclined with respect to the longitudinal direction of the lure body, and the front end is lower than the rear end. With this configuration, in the state where the longitudinal direction of the lure is horizontal, the shaft is configured in a slanted shape with the front end facing down, so that the weight can be easily moved forward. Therefore, the weight can be moved forward without greatly tilting the front end of the lure downward.

  According to the present invention, since a magnet such as a magnet piece is not used, each member can be made of a general-purpose material. Since the weight moves along the shaft, the lure is moved when the weight moves. There is no collision with the body. Furthermore, at the weight stop position, the weight surface is pressed by repulsion due to elastic deformation of the shaft inserted through the weight, and the movement of the weight is stopped by being sandwiched between the shaft and the contact portion. Become. And since this shaft does not need to be a special material, it can be manufactured cheaply.

  Further, according to the configuration in which the abutting portion has the arc-shaped protruding portion, when the weight surface abuts on the abutting portion, even if the portion that abuts on the weight surface may be different, any of the arc-shaped protruding portions The portion comes into contact with the weight surface and the weight can be held by the repulsive force of the shaft.

  Furthermore, according to the configuration in which the engaging recess is provided on the weight surface, the portion of the arc-shaped protruding portion that protrudes most toward the weight surface is engaged with the engaging recess, thereby causing repulsion due to elastic deformation of the shaft. Not only the pressing force to the weight surface, but also the weight stop state by the locked state can be realized, and the weight stop state becomes stable.

  When the weight is formed in a cylindrical shape, a desired weight can be obtained by adjusting the length of the weight. And if it is the structure which contact | abuts an annular periphery at two places, the holding | grip by a weight and a contact part can be ensured. Furthermore, the engaging recess is provided over the entire circumference in the circumferential direction at a predetermined position on the weight surface, so that the locked state by the arc-shaped protrusion can be obtained in the same state even when the weight rotates around the shaft. In addition, when the through-hole is provided at an eccentric position or the weight shape is deformed, the vertical direction of the weight inside the lure is constant, so the engaging recess is formed only on the surface located above the weight. By doing so, a stable locked state can be obtained.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present embodiment relates to a luer called a plug configured to resemble a small fish in appearance, and as shown in FIG. 1, the luer body 1 has a space portion 11 for making the interior of the lure hollow. It is configured. Then, the shaft 2 and the weight 3 are built in using the space portion 11.

  The shaft 2 is disposed between a support portion 13 configured in the lure body 1 for mounting an eyelet (fishing hook connecting ring) 12 and an internal partition wall 14 b fixed at an appropriate position of the space portion 11. Yes. The support portion 13 of the eyelet 12 is configured at a position closer to the head (front end) 1a than the center of the lure body 1, and the internal partition wall 14b is formed in the vicinity of the tail (rear end) 1b of the lure body 1. . Accordingly, the axis of the shaft 2 disposed between the support portion 13 and the internal partition wall 14b is disposed in a state along the longitudinal direction (front-rear direction) of the lure. A stopper 14a is provided in the middle between the support portion 13 and the internal partition wall 14b. The stopper 14a is provided with a through hole 40, and the shaft 2 is loosely inserted into the through hole 40. Is arranged.

  The weight 3 includes a cylindrical main body 31 and a through hole 32 provided at the center thereof, and the shaft 2 is inserted through the through hole 32 (see FIG. 1B). Therefore, the weight 3 can move by its own weight along the inclined shaft 2 when the lure is inclined and the shaft 2 is inclined. At this time, the range in which the weight 3 can move is the range from the stopper 14a to the internal partition 14b. The stopper 14 a functions as a stopper in front of the weight 3.

  The through hole 40 of the stopper 14a is a long hole that is long in the vertical direction in the vicinity of the center, and even if the shaft 2 is elastically deformed vertically by the long hole 40, A repulsive force due to elastic deformation of the shaft can be sufficiently obtained without contacting the inner surface. Further, the long hole 40 is configured to be smaller than the area of the front end face of the weight 3 so that it does not pass through the long hole 40 even if the weight 3 abuts against the stopper 14a.

  Due to such a configuration, when the weight 3 is moved to the lure tail portion 1b during casting, the head 1a is directed upward to descend to the internal partition 14b by its own weight. In the reeling after landing, the weight 3 moves toward the stopper 14a by the head 1a being positioned below the tail 1b. The posture in which the lure after landing faces the head 1a downward is relatively easy because the lip 15 is subjected to water resistance when the lure is advanced, so that the lure sinks from the head 1a. It is possible by operation.

  Depending on the type of lure, there is one in which the lip 15 is not formed. In this case, as shown in FIG. 2, a lure body 1 is inserted by inserting a second weight 303 different from the weight 3 through the shaft 2 and disposing it between the support portion 13 and the stopper 14a. Can be moved to the head. Thereby, the head 1a of the lure at the time of landing is easily turned downward in the water. Since the stopper 14a exists between the weights 3 and 303, the second weight 303 does not move, only the first weight 3 moves, and the weight 3 and the weight 303 are in contact with each other. No impact sound is generated by contact between weights.

  Further, if the shaft 2 is inserted through the through hole 32 of the weight 3 as in the present embodiment, the weight 3 moves only in the range where the shaft 2 is provided. It is not necessary to provide a special space for rolling or the like in the luer body 1, and the weight 3 can be moved within an appropriate range of the space portion 11. Thereby, even lures of different types or sizes can be freely designed. If the length of the shaft 2 is changed, the moving range of the weight 3 can be easily changed. When the length of the shaft 2 is long, the change in the center of gravity of the lure due to the movement of the weight 3 becomes clearer, and the lure operation during casting and reeling becomes easier. At this time, in order to further clarify the change in the center of gravity of the lure, the length of the shaft 2 is preferably set to, for example, 60 mm or more.

  In the present embodiment, the abutting portion 4 is provided in the vicinity of the support portion 13 in order to fix the position of the weight 3. The abutment portion 4 is provided at a position where it can abut against the surface of the weight 3. When the weight 3 moves toward the stopper 14 a, the weight 3 moved against the fixed shape of the abutment portion 4 is The position is fixed by being pressed by the repulsion of the elastic deformation of the shaft 2. The pressure due to the repulsion of the shaft 2 acts on the weight 3 toward the abutting portion 4, and a part of the weight 3 located between the shaft 2 and the abutting portion 4 is held by this pressing force. It becomes a state. At this time, in order to obtain repulsion due to elastic deformation of the shaft 2, the diameter of the shaft 2 is preferably about 9 mm.

  Here, the detail of the contact part 4 is demonstrated. As shown in FIG. 3A, the contact portion 4 is provided with an arc-shaped protrusion 42 below the contact portion 4. Then, when the arcuate protrusion 42 abuts on the weight 3, a part of the weight 3 is pressed by pressing due to the elastic deformation of the shaft 2.

  Therefore, as shown in FIGS. 3B to 3D, when the weight 3 moves from the tail portion 1b of the lure toward the head portion 1a, the front end portion of the weight 3 first comes into contact with the arcuate protrusion 42. (Refer to FIG. 3B). This abutment position is determined by the relative positional relationship between the weight 3 and the abutment portion 4, but is adjusted so that only the lowest part (the most projecting point) of the arcuate protrusion 42 does not abut. Yes. That is, when the weight 3 comes into contact with the arcuate protrusion 42, the shaft 2 is elastically deformed, and a pressing force is applied by the repulsion of the shaft 2. Therefore, only the lowest part of the arcuate protrusion 42 is the weight 3. This is because the elastic deformation of the shaft 2 cannot be expected when it comes into contact with the surface, and the resulting pressing force becomes very small. Therefore, it is preferable that the front end portion of the weight 3 starts abutting at a higher position (an arc-shaped start point or end point) than the lowest portion of the arc-shaped protrusion 42 (see FIG. 3C).

  Next, as the movement of the weight 3 proceeds, the shaft 2 is elastically deformed and the movement of the weight 3 is allowed (see FIG. 3C). At this time, the arcuate protrusion 42 resists the surface of the weight 3 and the movement of the weight 3 is decelerated by the resistance force. At this time, the shaft 2 is elastically deformed by the arcuate protrusion 42, but the weight 3 presses the arcuate protrusion 42 by repelling the shaft 2. At the arcuate apex of the arcuate protrusion 42, the pressing force against the arcuate protrusion 42 by the weight 3 is the strongest, the movement of the weight 3 is decelerated, and finally the movement of the weight 3 is stopped.

  As described above, when the surface of the weight 3 is locked by the arc-shaped protruding portion 42 applied to the contact portion 4, a part of the weight 3 located between the shaft 2 and the contact portion 4 is locked by the locking. It will be in the state clamped by the protrusion part 42. FIG. Therefore, even if the lure vibrates in water, the weight 3 clamped by the shaft 2 and the arcuate protrusion 42 that are fixedly arranged inside the lure body 1 is not affected by the shaft 2 and the arcuate protrusion. 42 and vibrate integrally with each other, and no sound is generated by colliding with the inner wall surface of the lure body 1.

  Further, in the present embodiment, a stopper 14a capable of stopping the movement of the weight 3 is provided at a position where the pressing force by the contact portion 4 can be received. Even if the weight 3 moves forward beyond the state in which the lowermost portion of the arcuate protrusion 42 presses the vicinity of the center in the longitudinal direction of the weight 3 (see FIG. 3C), the weight 3 contacts the stopper 14a. Since it stops at the contact position (see FIG. 3D), it can be stopped while receiving the elastic force of the shaft 2.

  Next, another embodiment of the present invention will be described. First, as shown in FIG. 4A, there is an embodiment in which an engaging recess 33 is formed on the surface of the weight 3. The engaging recess 33 is provided in a groove shape over the entire circumference along the circumferential direction on the surface of the cylindrical weight body 31. In the above-described embodiment, the through-hole 32 is formed in the cylindrical weight main body 31 and the shaft 2 is inserted into the through-hole 32. Therefore, the weight 3 is fixed only in contact. It relied on the pressing force by the pinching of the part 4 and the shaft 2. However, in the case of a lure that is expected to vibrate greatly, there is a limit to the fixing with only the contact portion 4. Therefore, in the case of such a type of lure that is expected to vibrate greatly, this embodiment is suitable for stabilizing the fixed state of the weight 3.

  That is, since the contact portion 4 has the arc-shaped protruding portion 42 as described above, and the engagement recess 33 is provided in the weight main body 31, when the weight 3 moves to an appropriate position, the contact portion 4 can lock the weight 3 and limit the movement of the weight 3 as described above. Furthermore, in order to obtain a state where the part of the arcuate protrusion 42 located at the lowest position engages (or abuts) into the engaging recess 33 of the weight 3 and is locked to some extent, the cylinder of the weight 3 Engaging recesses can be formed on the outer surface of the shape (see FIG. 4B). Accordingly, the stop position of the weight 3 is fixed by the above-described locking, and a stable fixed state can be obtained because it does not depend only on the pressing force caused by the holding portion 4 and the shaft 2 being pinched. In this case, the presence of the stopper 14a is preliminary. In other words, when the weight 3 moves toward the stopper 14a, the weight 3 is stopped by the pressing force by the nipping between the contact portion 4 and the shaft 2 or the engagement of the arcuate protrusion 42 into the engagement recess 33. When the movement is fast, that is, the inertia force is large and the arc-shaped protrusion 42 cannot be engaged with the engagement recess 33, the stopper 14a stops the movement of the weight 3 (FIG. 4C). reference). Even if the weight 3 is stopped once by the stopper 14a, when the lure is vibrated and the weight 3 may be retracted, the weight 3 is retracted, so If the insertion recess 33 moves to a position where it can accept the engagement of the arc-shaped protrusion 42, the locking by the arc-shaped protrusion 42 can be realized, and even if the weight 3 may not move backward, It is fixed stably at the position stopped by the stopper 14a.

  Further, other embodiments will be described. First, there is another embodiment by changing the shape of the contact portion 4. The abutting portion 4 may have any shape as long as the weight 3 can be locked, and can have various shapes in order to facilitate the engagement of the weight 3 as well as the arc shape described above. For example, as shown in FIG. 5A, it is conceivable that a part of the arc-shaped protruding portion 42 with which the weight 3 abuts and locks is a flat surface and the engaging portion is an arc-shaped abutting portion 104. In this case, since the engaging portion is arcuate, the weight 3 is easily engaged, and the weight 3 is stopped by the stopper 14a. At the same time, since the locking portion of the weight 3 is a flat surface, the contact portion of the weight 3 has more contacts than in the case where the whole is arcuate, and the locking force to the weight 3 is increased, and the whole is arcuate. It will be more stable. Moreover, as shown in FIG.5 (b), it can also be set as the shape which made the contact part 4 inclined forward, so that it goes to the lure front end. In this case, as the weight 3 moves, the locking force applied to the weight 3 increases, and the locking force becomes maximum at the lowest position of the contact portion 4. By doing so, the weight 3 does not vibrate even when the lure is reeled, and a stable state can be maintained.

  In the configuration in which the engagement concave portion 33 is provided in the weight main body 31, it can be considered to have a configuration that protrudes small in order to facilitate the engagement of the arc-shaped protruding portion 42 into the engagement concave portion 33. In this embodiment of the present invention, as shown in FIG. 6, an arc-shaped protruding portion 42 is provided by partially protruding the contact portion 4 in an arc shape (see FIG. 6A). ). In the case of this embodiment, only the partial arcuate protrusion 42 abuts on the surface of the weight 3, and the locking of the weight 3 is performed by the tip portion 43 including the arcuate protrusion 42 of the abutment 4. Become.

  By adopting the configuration as in the present embodiment, when the weight 3 moves, the distal end portion 43 including the arcuate protrusion 42 is engaged with the engagement recess 33 of the weight 3 to lock the weight 3. It becomes. (See FIG. 6 (b)). With such a configuration, the stop position of the weight 3 is ensured, and the weight 3 is stopped by the locking force of the contact portion 4 even when the arcuate protrusion 42 cannot be engaged with the engagement recess 33 of the weight 3. The state can be secured.

  Each of the above embodiments shows the same operation mode. That is, when casting, the weight 3 is moved so as to be close to the tail of the lure, and the center of gravity of the entire lure is set to the tail side. The movement at this time is by detaching the weight 3 from the contact portion 4 by giving an impact to the lure or the like. Then, after the lure has landed by casting, starting the reeling causes the lure to submerge, so that the weight 3 moves toward the head that is directed downward. The weight 3 reaching the contact portion 4 by this movement is fixedly held by the contact portion 4 as described above.

  Although the present embodiment is as described above, various aspects can be taken without departing from the spirit of the present invention. For example, the shape of the weight 3 has been described by exemplifying an embodiment using a cylindrical configuration, but the weight 3 can have various shapes or embodiments. Therefore, the shape or aspect of the weight 3 will be briefly described.

  The weight 3 shown in FIG. 7A is that of the embodiment already described. The arc-shaped protruding portion 42 of the contact portion 4 that locks the surface of the weight 3 is in contact with the surface of the weight 3 while being in contact therewith. Therefore, after all, the weight 3 locked by the contact portion 4 stops in a state of being sandwiched between the shaft 2 and the arcuate protrusion 42, and its position is determined.

  The weight 103 shown in FIG. 7B has a rod shape with an elliptical cross section as a whole. In this case, in order to stabilize the posture of the weight 103, the through hole 132 is provided eccentrically. That is, the weight 103 supported by the shaft 2 has its own center of gravity positioned below the through-hole 132, and therefore always maintains a posture in which the through-hole 132 is positioned higher as shown in the figure. It becomes. Also, with such an attitude, the portion sandwiched between the shaft 2 inserted through the through hole 132 and the contact portion 4 is constant, and the locking force by the contact portion 4 can be easily adjusted (see FIG. 7 (c)). That is, when the cylindrical weight 3 is used, a through hole is provided at the center thereof, and the weight 3 can be rotated about the shaft 2, so that the portion in contact with the contact portion 4 is not constant. Therefore, when the engaging recess is configured, it must be configured around the entire circumference, but if the abutting portion is constant, it may be configured only in the abutting portion when the engaging recess is provided. Become. In addition, in the cylindrical weight 3, if the through hole is substantially at the center, the position of the center of gravity is also located in the vicinity of the through hole, so that it can function as a cylindrical weight. Since the gap dimension between the inner surface and the inner surface is slightly different, the locking force of the contact portion 4 may change depending on the state of the weight 3.

  Moreover, as shown in FIG. 8, the contact part 4 can also be arrange | positioned in two places. For example, the abutment portion 4 can be disposed on the outer peripheral edge of the weight 3 with an annular cross section so as to be substantially C-shaped. In this way, when the number of the arcuate protrusions 42 is one, the pressing force due to the repulsion of the elastic deformation of the shaft 2 is stabilized in a certain direction due to the vibration of the abutting weight 3 during reeling. Although there is a possibility that it cannot be obtained, the pressing force of the shaft 2 can be stably obtained in a certain direction by arranging the contact portion 4 in a substantially C shape, and the weight 3 does not vibrate, It is pressed by the nipping between the contact part 4 and the shaft 2 and can be made more stable.
