Description

  The present invention relates to a fishing spinning reel, and more particularly to a fishing spinning reel in which a spool reciprocating device that converts a rotational operation motion of a handle into a longitudinal reciprocating motion of a spool is provided in the reel body.

  Generally, a fishing spinning reel rotates a rotor having a fishing line guide by rotating a handle, and converts the rotational movement of the handle into a longitudinal movement direction by a spool reciprocating device provided inside the reel body. The fishing line is wound around the reciprocating spool via the fishing line guide portion of the rotor.

Conventionally, in such a spinning reel for fishing, it is accompanied by a fish hit by a pulling operation of an operation lever attached to the reel body so as to be able to pull upward or a rotation operation of an operation tool provided at a rear portion of the reel body. A rotor braking device that applies a braking force to a rotor that rotates in reverse by the feeding of a fishing line, and allows the rotor to rotate freely, while allowing the operator to interact with the fish by rotating operation, etc. (For example, see Patent Document 1 and Patent Document 2).
No. 1-20858 Japanese Utility Model Publication No. 1-39194

  However, in such a fishing spinning reel, the spool reciprocates back and forth at a high speed in conjunction with the reverse rotation of the rotor. For this reason, the vibration generated in response to the back-and-forth reciprocating motion may cause the operator to feel uncomfortable, cause the fish to feel uncomfortable via the fishing line, cause the fish to go out, and cause the fish to escape or cut the fishing line. In addition, there is a problem that it is transmitted to the screw fastening portion of the reel body and causes loosening of the screw.

  Further, since the spool reciprocates back and forth at a high speed in conjunction with the reverse rotation of the rotor, the conversion engagement portion (for example, the worm shaft and the pin engagement portion, the engagement protrusion and the engagement groove) in the spool reciprocation device There is a problem of causing deterioration of freeness at the time of reverse rotation of the rotor due to wear or resistance generation at the time of reciprocating forward and backward movement.

  The present invention has been made in view of the above-described problems, and can solve various problems caused by vibrations generated during the reverse rotation of the rotor, as well as the durability of the spool reciprocating device and the reverse rotation of the rotor. An object of the present invention is to provide a fishing spinning reel excellent in freeness at the time.

  In order to achieve the above-described object, a fishing spinning reel according to the present invention includes a rotor having a fishing line guide that rotates in response to a rotation operation of a handle shaft and guides the fishing line to the spool, and a spool attached to the tip. One-way clutch that transmits power so that the spool shaft does not reciprocate back and forth during reverse rotation of the rotor that pulls out the fishing line while rotating the spool shaft forward and backward when the rotor rotates forward to wind the fishing line around the spool The spool reciprocating device includes a restricting means for restricting unnecessary movement of the spool shaft due to the weight of the spool.

  According to the spinning reel for fishing having the above-described configuration, the spool reciprocating device does not reciprocate the spool shaft back and forth during rotation of the rotor that pulls the fishing line out of the spool, and thus occurred according to the back and forth reciprocation of the spool. Since the vibration can be prevented, it is possible to improve the fishing result by removing the discomfort in the operator due to the vibration and reducing the influence on the fish.

  Further, since the spool shaft is prevented from reciprocating back and forth during rotation of the rotor that draws the fishing line from the spool, it is possible to avoid wear of a member that converts the spool reciprocating device into back-and-forth reciprocating motion. It is possible to provide a reel having excellent durability. Further, it is possible to avoid a situation in which the freeness at the time of reverse rotation of the rotor is deteriorated due to the occurrence of resistance at the time of the reciprocating movement of the spool, so that a reel having excellent freeness at the time of reverse rotation of the rotor is provided. Can do.

  Furthermore, since the unnecessary movement of the spool shaft due to the weight of the spool is restricted by the regulating means provided in the spool reciprocating device, it is possible to prevent unnecessary movement due to the weight of the spool unrelated to the operator's intention. A situation in which the thread winding state of the winding drum portion of the spool is deteriorated can be prevented, and the operability in the spinning reel for fishing can be improved.

  In the above-described configuration, the spool reciprocating device includes, for example, a worm shaft that rotates in response to the rotation operation of the handle shaft and has a spiral groove formed on its peripheral surface, and a engagement that is fixed to one end of the spool shaft and engages with the spiral groove. It is conceivable to provide a slider having a mating pin and a gear for transmitting the rotation of the handle shaft to the worm shaft, and to dispose a one-way clutch at a connecting portion between the worm shaft and the gear. In this case, the above-described effect can be obtained in a fishing spinning reel having a spool reciprocating device using a worm shaft.

  In the above configuration, the regulating means provided in the spool reciprocating device prevents unnecessary movement of the spool shaft due to its own weight by preventing the worm shaft from spinning in the rotational direction in which power transmission by the one-way clutch is allowed. Is preferably regulated. In this case, since the rotation of the worm shaft is prevented by the restricting means provided in the spool reciprocating device, unnecessary rotation of the worm shaft is restricted. It becomes possible to prevent movement.

  In particular, in the above configuration, it is conceivable that the restricting means for restricting unnecessary movement of the spool shaft due to the weight of the spool is constituted by a friction generating member that generates friction between the worm shaft and the gear. In this case, since the friction generating member as the restricting means disposed between the worm shaft and the gear prevents the worm shaft from spinning freely, unnecessary rotation of the worm shaft is limited. Unnecessary downward movement of the spool that is unrelated to the intention of

  Further, in the above configuration, the restriction means provided in the spool reciprocating device sets the angle of the groove portion of the spiral groove used for the movement of the spool shaft during the backward movement to an angle that resists the movement of the spool shaft due to the weight of the spool. Thus, unnecessary movement of the spool shaft due to its own weight may be restricted. In this case, the worm shaft can be prevented from idling by setting the angle of the spiral groove for movement when the spool shaft of the worm shaft is moved backward to an angle that resists the downward movement of the spool due to its own weight. Thus, unnecessary rotation of the worm shaft is limited, and unnecessary downward movement of the spool that is unrelated to the operator's intention can be prevented.

  In the above configuration, the spool reciprocating device includes, for example, a drive gear that rotates in response to a rotation operation of the handle shaft, a driven gear that is driven by the drive gear, and a control that includes an engagement protrusion that is disposed to face the driven gear. And a slider formed with an engagement groove fixed to one end of the spool shaft and engaged with an engagement protrusion, and the one-way clutch may be disposed between the driven gear and the control body. Conceivable. In this case, the above-described effect can be obtained in a fishing spinning reel having a spool reciprocating device using a drive gear and a driven gear.

  Furthermore, in addition to the above-described configuration, when a rotor braking mechanism that applies a braking force to the rotation of the rotor that draws the fishing line from the spool is provided, the vibration that has occurred during the reverse rotation of the rotor is removed. It becomes possible to concentrate on the operation with respect to the mechanism, and it is possible to perform fishing while enjoying the interaction with the fish further.

  ADVANTAGE OF THE INVENTION According to this invention, while being able to solve the various problems resulting from the vibration which generate | occur | produces at the time of reverse rotation of a rotor, the spinning spinning for fishing excellent in durability of a spool reciprocating device and free property at the time of rotor reverse rotation Reels can be obtained.

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

  FIG. 1 shows the overall configuration of a fishing spinning reel according to a first embodiment of the present invention.

  As shown in FIG. 1, a reel body 1 of a fishing spinning reel according to the present invention is integrally formed with a reel leg 2 attached to a fishing rod, and a rotor 3 rotatably supported in front thereof. And a spool 4 supported so as to be movable back and forth in synchronism with the rotational movement of the rotor 3.

  The rotor 3 includes a pair of arm portions 3a that rotate around the spool 4, and a bail support member 3c having a base end portion of the bail 3b attached to the front end portion of each arm portion 3a is used for winding a fishing line. It is rotatably supported between the position and the fishing line discharge position. Note that one base end portion of the bail 3b is attached to a fishing line guide portion 3d provided integrally with the bail support member 3c.

  A handle shaft 5 is rotatably supported in the reel body 1, and a handle 6 is attached to the protruding end portion. Further, a winding drive mechanism is engaged with the handle shaft 5, and the winding drive mechanism includes a drive gear (face gear) 7 mounted on the handle shaft 5 so as to be integrally rotatable, and the drive gear 7. And a pinion 8 extending in a direction perpendicular to the handle shaft 5 and having a hollow portion extending in the axial direction therein.

  The pinion 8 is rotatably supported in the reel main body 1 via a pair of bearings 9 arranged at the front and rear. Moreover, it extends toward the spool 4 side, and the rotor 3 is attached at the tip. A one-way clutch 10 is attached to an intermediate portion of the pinion 8, and the one-way clutch 10 is operated by rotating a lever 11 provided outside the reel body 1, and the handle 6 (the rotor 3 ) Is configured to constitute a known reverse rotation prevention device for preventing reverse rotation in the fishing line feeding direction.

  A spool shaft (main shaft) 12, which extends in a direction perpendicular to the handle shaft 5 and has the spool 4 mounted on the tip side, is inserted into the hollow portion formed inside the pinion 8 so as to be movable in the axial direction. . The pinion 8 is engaged with a spool reciprocating device 13 for reciprocating the spool 4 (spool shaft 12).

  The spool reciprocating device 13 is rotatably supported in the reel body 1 and extends in parallel with the spool shaft 12. The slider 15 is secured to the base end portion of the spool shaft 12. The gear 16 is attached to the end of the worm shaft 14 and meshes with the pinion 8. Between the worm shaft 14 and the gear 16, a one-way clutch 17, which will be described later, is disposed in order to transmit only the rotational driving force in the rotation of the handle 6 in the fishing line winding direction to the worm shaft 14.

  The slider 15 includes a main body 15a that is fixed to the spool shaft 12 by screws or the like. The main body 15a engages with a spiral groove 14a formed on the outer peripheral surface of the worm shaft 14. The engagement pin 15b is held. When the worm shaft 14 is rotationally driven, the slider 15 is reciprocated in the front-rear direction via the engagement pin 15b.

  In the fishing spinning reel having such a configuration, when the winding operation is performed by the handle 6, the rotor 3 is driven to rotate through the winding drive mechanism, and the spool 4 is moved through the spool reciprocating device 13. Since it is reciprocated back and forth, the fishing line is wound evenly around the winding body 4a of the spool 4 via the fishing line guide 3d.

  Next, the configuration and operation of the one-way clutch 17 disposed in the gear 16 of the spool reciprocating device 13 will be described. FIG. 2 is an enlarged view around the gear 16 of the spool reciprocating device 13, and FIG. 3 is a cross-sectional view taken along the line AA shown in FIG. In the following description, the clockwise rotation as viewed from the left side of FIG. 2 is referred to as normal rotation, and the counterclockwise rotation is referred to as reverse rotation.

  When the operator rotates the handle 6 in the fishing line winding direction, the drive gear 7 is rotationally driven in the direction of arrow B shown in FIG. 2 and the gear 16 is driven in reverse via the pinion 8. On the other hand, when the rotor 3 is driven reversely by feeding the fishing line by the fish, the gear 16 is driven forward via the pinion 8 accordingly.

  As shown in FIG. 3, the one-way clutch 17 includes an outer ring 21 that is housed in a state of being prevented from rotating inside the gear 16, a rolling member 22 that is disposed between the outer ring 21 and the worm gear 14, A spring 23 that applies a biasing force in a certain direction to the rolling member 22 and a holding member 24 that restricts the movement of the rolling member 22 by the biasing force of the spring 23 are configured. The outer ring 21 is provided with a wedge region and a free space according to the size of each rolling member 22, and is configured such that the rolling member 22 moves between both according to the rotation direction of the gear 16.

  Specifically, when the gear 16 is driven in reverse rotation (counterclockwise direction in FIG. 3) in accordance with the fishing line winding operation, the driving force is transmitted to the one-way clutch 17. At this time, since the rolling member 22 of the one-way clutch 17 shifts to the wedge region by the biasing force of the spring 23, the driving force of the gear 16 is transmitted to the worm shaft 14 via the one-way clutch 17 (note that the worm shaft 14). Is driven in reverse). On the other hand, when the gear 16 is driven to rotate forward (clockwise in FIG. 3) in accordance with the feeding of the fishing line by the fish, the driving force is transmitted to the one-way clutch 17. At this time, the rolling member 22 of the one-way clutch 17 shifts to the free space of the outer ring 21 against the urging force of the spring 23, so that the driving force of the gear 16 is not transmitted to the worm shaft 14.

  In this way, the one-way clutch 17 is interposed between the gear 16 that meshes with the pinion 8 and the worm shaft 14, and the rotational driving force when the rotor 3 rotates in the direction in which the fishing line is pulled out from the spool 4 is transmitted to the worm shaft 14. Therefore, even when the fishing line is fed out by the fish, the worm shaft 14 does not rotate. For this reason, since the spool 4 does not reciprocate back and forth, it is possible to prevent vibration that has conventionally occurred in accordance with the back and forth reciprocation of the spool 4. As a result, it is possible to solve all the problems that have occurred due to this vibration.

  That is, it is possible to remove the uncomfortable feeling of the operator due to the vibration generated in response to the back-and-forth reciprocation of the spool 4, so that it is possible to perform the fishing line feeding operation by the reverse rotation of the rotor 3. Moreover, since it is possible to prevent the fish from feeling uncomfortable through the fishing line due to the vibration, it is possible to avoid a situation in which the fish is violated by the uncomfortable feeling and the fish is taken away or the fishing line is cut off. As a result, the influence on the fish can be minimized, and the fishing results can be improved. Furthermore, since the situation where the screw fastened to the reel body 1 is loosened due to the vibration can be avoided, the cost and time required for maintenance of the reel body 1 and the like can be reduced.

  Further, even when the rotor 3 rotates in the reverse direction, the worm shaft 14 does not rotate, so that the spiral groove 14a and the engagement pin 15b in the spool reciprocating device 13 are worn according to the back-and-forth reciprocating motion of the spool 4 as in the prior art. Since the situation can be avoided, the durability of the spool reciprocating device 13 can be improved. Further, since the worm shaft 14 does not rotate even when the rotor 3 rotates in the reverse direction, it is possible to avoid the situation where the freeness at the time of the reverse rotation of the rotor 3 is deteriorated due to the generation of resistance when the direction of the spool 4 is changed back and forth. Therefore, the fishing line can be fed out comfortably.

  In the spinning reel for fishing according to the first embodiment, the one-way clutch 17 is disposed between the worm shaft 14 and the gear 16 so that the rotor 3 rotates in the reverse direction when the fishing line is fed out. The rotation of the worm shaft 14 is prevented. However, since the rotation of the worm shaft 14 in the forward rotation direction of the rotor 3 (counterclockwise rotation) is not restricted, for example, when the fishing rod is raised from the horizontal state, There may occur a situation in which the worm shaft 14 idles in the rotation direction and the spool 4 moves regardless of the operator's intention.

  FIG. 4 is an enlarged view around the gear 16 of the spool reciprocating device 13 when the fishing rod is raised from a horizontal state. FIG. 4 shows a case where the spool 4 is arranged at a position closer to the upper end side (left end side shown in FIG. 1).

  As shown in FIG. 4, when the fishing rod is raised from the horizontal state, if the spool 4 is arranged at a position closer to the upper end side, the spool 4 tends to move downward due to its own weight. A load is applied to the coupling pin 15b. When the spool 4 is about to move downward, the rotor 3 rotates forward. In the above configuration, the rotation of the worm shaft 14 in the rotation direction when the rotor 3 is rotating forward is not restricted. Therefore, when a load due to the weight of the spool 4 is applied, the engagement pin 15b descends along the spiral groove 14a, and the worm shaft 14 is moved in the direction of arrow A shown in FIG. 4 (when FIG. 4 is viewed from above). Rotate counterclockwise. As a result, the spool 4 moves downward regardless of the operator's intention.

  In this way, when the spool 4 moves regardless of the operator's intention, it may adversely affect the operation surface of the fishing spinning reel, such as the thread winding state of the winding body 4a of the spool 4 being deteriorated. It is desirable to remove as much as possible. For this reason, in the spinning reel for fishing according to Embodiment 1, the spool reciprocating device 13 is provided with a regulating member that regulates unnecessary movement of the spool 4 due to its own weight. By using such a restricting member, the above-described idle rotation of the worm shaft 14 is prevented, thereby restricting the downward movement of the spool 4 due to its own weight.

  In order to prevent the worm shaft 14 from idling, for example, a friction generating member (hereinafter referred to as “friction generating member”) that functions as a restricting member is disposed between the worm shaft 14 and the gear 16. Alternatively, the worm shaft 14 itself may function as a regulating member by adjusting the angle of the spiral groove 14 a formed on the peripheral surface of the worm shaft 14. Hereinafter, an example in which the friction generating member is disposed will be described, and then an example in which the angle of the spiral groove 14a is adjusted will be described.

  FIG. 5 is an enlarged view of the periphery of the gear 16 of the spool reciprocating device 13 when a friction generating member is provided. FIG. 5 shows a case where an O-ring 25 (elastic rubber ring) is attached as a friction generating member between the worm shaft 14 and the gear 16. The friction generating member is not limited to the O-ring 25 and may be a member such as a leaf spring or a coil spring as long as it can generate friction that prevents the worm shaft 14 from idling.

  As described above, the restricting member made of a friction generating member is disposed between the worm shaft 14 and the gear 16 to prevent the worm shaft 14 from spinning freely, thereby preventing unnecessary rotation of the worm shaft 14. In addition, unnecessary downward movement of the spool 4 unrelated to the operator's intention can be prevented. As a result, a situation in which the thread winding state of the winding body 4a of the spool 4 is deteriorated can be prevented, and the operability of the fishing spinning reel can be improved.

  On the other hand, FIG. 6 is an enlarged view of the worm shaft 14 when the angle at which the spiral groove 14a is formed is adjusted. In the spiral groove 14a shown in FIG. 6, the forward movement groove portion 141 used for the movement of the spool 4 (spool shaft 12) during the forward movement (movement of the reel body 1 in the forward direction (leftward direction shown in FIG. 1)). And the angle with respect to the worm shaft 14 is changed between the spool 4 and the backward movement groove 142 used for the backward movement of the spool 4 (the movement of the reel body 1 in the rearward direction (rightward direction in FIG. 1)). Yes. In the case where the fishing rod is raised, when the spool 4 moves due to its own weight, among these groove portions, the engaging pin 15b descends through the backward movement groove portion 142.

  In the present embodiment, an angle of the backward movement groove portion 142 with respect to a direction orthogonal to the extending direction of the worm shaft 14 (hereinafter referred to as “an angle of the backward movement groove portion 142”) is defined as an angle of the worm shaft 14 in the forward movement groove portion 141. The size is equal to or smaller than an angle with respect to a direction orthogonal to the extending direction (hereinafter referred to as “an angle of the forward movement groove portion 141”). Specifically, the angle of the backward movement groove 142 is set to an angle that resists the downward movement of the spool 4 due to its own weight, and the angle of the forward movement groove 141 is larger than the angle of the backward movement groove 142.

  The angle of the backward movement groove 142 may be any value as long as it can resist the downward movement of the spool 4 due to its own weight on the assumption that the spool 4 moves backward smoothly. Consists of degrees. On the other hand, the angle of the forward movement groove portion 141 is set to any value as long as the angle is equal to or larger than the angle of the backward movement groove portion 142 on the assumption that the spool 4 moves forward smoothly similarly to the backward movement groove portion 142. For example, it is configured at 16 to 22 degrees.

  It is sufficient that the angle of the backward movement groove portion 142 is formed so that the spool 4 does not move downward due to its own weight, and the angle of the forward movement groove portion 141 is, for example, the angle (8 to 11 degrees) of the backward movement groove portion 142. You may form similarly.

  In this way, the angle of the backward movement groove 142 formed on the peripheral surface of the worm shaft 14 is set to be an angle that resists the downward movement of the spool 4 due to its own weight, thereby preventing unnecessary rotation of the worm shaft 14. Unnecessary downward movement of the spool 4 unrelated to the intention can be prevented. As a result, a situation in which the thread winding state of the winding body 4a of the spool 4 is deteriorated can be prevented, and the operability of the fishing spinning reel can be improved.

  Further, a new member may be appropriately added to the spool reciprocating device 13 in order to obtain further excellent effects while maintaining the configuration as described above. For example, you may make it add the member which reinforces the connection part of the one-way clutch 17 in the worm shaft 14. FIG.

  That is, in the above-described configuration, the one-way clutch 17 is disposed between the worm shaft 14 and the gear 16 in order to prevent the worm shaft 14 from rotating in the rotation direction when the rotor 3 rotates in the reverse direction. The connecting portion with the one-way clutch 17 is required to have a certain degree of strength in order to transmit the driving force when winding the fishing line. For example, the worm shaft 14 is made of stainless steel (SUS) or carbon tool steel (SK). It must be made of a high-strength material. However, when the worm shaft 14 is made of such a material, the weight of the worm shaft 14 itself may greatly increase.

  In order to avoid such an increase in the weight of the worm shaft 14, adding a member that reinforces the connection portion of the one-way clutch 17 in the worm shaft 14 minimizes an increase in the weight of the worm shaft 14. Since it becomes possible to obtain the strength of the connecting portion with the one-way clutch 17, it is preferable as an embodiment. Reinforcing the connecting portion of the one-way clutch 17 in the worm shaft 14 can be realized, for example, by press-fitting a high-strength reinforcing member into the connecting portion.

  FIG. 7 is an enlarged view around the gear 16 of the spool reciprocating device 13 when a high-strength reinforcing member is press-fitted into the worm shaft 14. FIG. 7 shows a case where a collar 26 is press-fitted as a reinforcing member into a connecting portion of the worm shaft 14 where the one-way clutch 17 is connected. Such a collar 26 is preferably provided with a high-strength material such as stainless steel (SUS) or carbon tool steel (SK).

  In this way, when a high-strength reinforcing member is press-fitted into the worm shaft 14 to reinforce the connection portion with the one-way clutch 17, portions other than the connection portion in the worm shaft 14 are made of aluminum (Al), titanium, or the like. It is possible to configure with a lightweight material. As a result, it is possible to obtain the strength of the connecting portion with the one-way clutch 17 while minimizing the increase in the weight of the worm shaft 14.

  As mentioned above, although the embodiment type | system | group of the spinning reel for fishing which concerns on this invention was demonstrated, this invention is not limited to the said embodiment, A various deformation | transformation is possible. In the above-described embodiment, the spool reciprocating device 13 using the worm shaft 14 is shown. However, for example, the configuration of the spool reciprocating device 13 may be appropriately modified according to the configuration of the spinning reel to be assembled. Is possible. For example, the present invention can be applied to a so-called gear oscillation type spool reciprocating device.

  Hereinafter, a second embodiment of the present invention will be described with reference to FIGS. In these drawings, FIG. 8 is a diagram showing the overall configuration of the fishing spinning reel according to the second embodiment, and FIG. 9 is a cross-sectional view taken along the line AA shown in FIG. FIG. In the embodiment described below, the same reference numerals are assigned to the same components as those in the first embodiment described above, and the detailed description thereof is omitted.

  The spool body 30 shown in FIG. 8 incorporates a spool reciprocating device 30 that moves the spool 4 (spool shaft 12) back and forth. The spool reciprocating device 30 is provided with a drive gear 31 (preferably formed integrally with the handle shaft 5) provided so as to be rotatable integrally with the handle shaft 5, and is rotatably supported by the reel body 1 so as to be driven. And a driven gear 32 that meshes with 31.

  A control body 33 that is rotatably supported by the reel body 1 is attached at a position facing the driven gear 32. The control body 33 is formed with an engaging projection 33a on an end surface that is eccentric from the center. The engagement protrusion 33 a is engaged in an engagement groove 35 formed in a slider 34 screwed to the rear end portion of the spool shaft 12. As a result, when the driven gear 32 and the control body 33 are rotationally driven through the drive gear 31 by the winding operation of the handle 6, the engagement protrusion 33a moves in the engagement groove 35 while moving along a predetermined rotation locus. As a result, the spool shaft 12 (spool 4) is converted into a back-and-forth reciprocating motion.

  As shown in FIG. 9, the control body 33 is rotatably attached to a projecting shaft 1a that is formed to project from the reel body 1, and a driven gear 32 is sandwiched between the control shaft 33 and a wall surface on which the projecting shaft 1a is formed. It is attached in the state. A one-way clutch 36 described later is disposed between the control body 33 attached to the protruding shaft 1a and the support portion of the driven gear 32. The one-way clutch 36 has the same configuration as the one-way clutch 17 according to the first embodiment, and transmits only the rotational driving force in the rotation of the handle 6 in the fishing line winding direction to the control body 33. Detailed description thereof is omitted.

  In the fishing spinning reel having such a configuration, when the winding operation is performed by the handle 6, the rotor 3 is driven to rotate through the winding drive mechanism and the spool 4 is moved through the spool reciprocating device 30. Since it is reciprocated back and forth, the fishing line is wound evenly around the winding body 4a of the spool 4 via the fishing line guide 3d.

  Next, the operation of the one-way clutch 36 of the spool reciprocating device 30 will be described. In the following description, clockwise rotation in the state seen from the front side in FIG. 8 (state seen from the left side in FIG. 9) is referred to as normal rotation, and counterclockwise rotation is referred to as reverse rotation. To do.

  When the operator rotates the handle 6 in the direction of winding the fishing line, the drive gear 31 is driven in reverse. When the drive gear 31 is driven in the reverse direction, the driven gear 32 is driven in the forward direction accordingly, and the driving force is transmitted to the one-way clutch 36. At this time, since the rolling member of the one-way clutch 36 is configured to move to the wedge region, the driving force is transmitted to the control body 33 (note that the control body 33 is driven to rotate forward). When the control body 33 is driven to rotate in the forward direction, the engagement protrusion 33a is guided while moving along a predetermined rotation locus in the engagement groove 35, and accordingly, the spool shaft 12 (spool 4) reciprocates back and forth. Do.

  On the other hand, when the rotor 3 rotates in the fishing line feeding direction by feeding the fishing line by the fish, the driving gear 7 and the driving gear 31 are driven to rotate forward via the pinion 8. When the drive gear 31 is driven to rotate in the forward direction, the driven gear 32 is driven to rotate in reverse, and the driving force is transmitted to the one-way clutch 36. At this time, since the rolling member of the one-way clutch 36 adopts a configuration that shifts to a free space, the driving force is not transmitted to the control body 33. For this reason, since the engagement projection 33a does not move, the spool shaft 12 (spool 4) does not reciprocate back and forth.

  In this manner, the control body 33 is provided with the engagement protrusion 33 a that engages in the engagement groove 35 formed in the slider 34, and the one-way clutch 36 is interposed between the driven gear 32 and the control body 33. In addition, since the rotational driving force during the reverse rotation of the rotor 3 is not transmitted to the control body 33, the control body 33 will not rotate even when the fishing line is fed out by the fish. For this reason, since the spool 4 does not reciprocate back and forth, it is possible to prevent vibration that has conventionally occurred in accordance with the back and forth reciprocation of the spool 4. As a result, it is possible to solve all the problems that have conventionally occurred due to this vibration, and to obtain the same effect as in the first embodiment.

  In the fishing spinning reel according to the second embodiment as well, when the fishing rod is raised from a horizontal state, the spool 4 rotates in the rotational direction in which the rotation of the control body 33 is allowed by the weight of the spool 4, and the spool 4 is operated. A situation may occur that moves regardless of the person's intention. In this case, the problem that the thread winding state of the winding body 4a of the spool 4 is deteriorated occurs as in the first embodiment. For this reason, also in the spinning reel for fishing according to Embodiment 2, the downward movement of the spool 4 due to its own weight is restricted by preventing the control body 33 from spinning around.

  As a method for preventing the control body 33 from idling, any configuration may be adopted. For example, as shown in FIG. 9, the side surface of the driven gear 32 and the side surface of the control body 33 are opposed to each other. It is conceivable to arrange a friction generating member (for example, an elastic O-ring 37) in the space to be formed. Note that the friction generating member is not limited to the elastic O-ring 37 as long as it can generate friction that prevents the control body 33 from idling, and may be configured by a member such as a leaf spring or a coil spring. This is the same as the first embodiment.

  As described above, since the friction generating member is disposed in the space formed in the portion where the side surface of the driven gear 32 and the side surface of the control body 33 are opposed to each other, the control body 33 is prevented from idling. This prevents unnecessary rotation of the spool 4 and prevents the spool 4 from moving downward regardless of the operator's intention. As a result, a situation in which the thread winding state of the winding body 4a of the spool 4 is deteriorated can be prevented, and the operability of the fishing spinning reel can be improved.

  Further, a member that restricts the movement of the slider 34 accompanying the movement of the spool 4 due to its own weight is maintained while maintaining the friction generating member that prevents the control body 33 from idling, or instead of the friction generating member. It may be added to the spool reciprocating device 30.

  Any member may be adopted as a member for restricting the movement of the slider 34. For example, the slider 34 may be moved in the forward direction of the spool 4 (forward direction of the reel body 1 ( An urging member for urging to the left)) side may be provided, and an inclined surface is provided inside the housing of the reel unit 1 and is in sliding contact with the inclined surface in a certain region. An elastic member may be attached to the lower end of the slider 34. Hereinafter, an example in the case where the urging member is provided will be described, and then an example in which an elastic member that is in sliding contact with the inclined surface provided inside the housing of the reel body 1 is attached to the lower end portion of the slider 34 will be described. To do.

  FIG. 10 is a cross-sectional view of the main part around the spool reciprocating device 30 when the urging member is provided. FIG. 10 shows a case where a coil spring 39 is attached to a guide 38 that guides the slider 34. The type of the urging member is not limited to the coil spring 39, and can be changed as appropriate including its attachment position. The coil spring 39 has a biasing force that resists downward movement due to the weight of the spool 4.

  The coil spring 39 for applying the urging force does not interfere with a normal fishing line winding operation in consideration of the own weight of the spool 4 and the power transmission efficiency of the spool reciprocating device 30, and moves downward due to the own weight of the spool 4. A spring having a spring force that can regulate the pressure is selected.

  As described above, since the coil spring 39 for biasing the slider 34 toward the moving direction when the spool 4 moves forward is provided, the slider 34 is prevented from moving due to the movement of the spool 4 due to its own weight. The downward movement of the spool 4 unrelated to the operator's intention can be prevented. As a result, a situation in which the thread winding state of the winding body 4a of the spool 4 is deteriorated can be prevented, and the operability of the fishing spinning reel can be improved.

  FIG. 11 is a cross-sectional view of the main part around the spool reciprocating device 30 when an elastic member slidably contacting with an inclined surface provided in the casing of the reel body 1 is attached to the lower end of the slider 34. is there. In FIG. 11, an inclined surface 40 is provided inside a casing of the reel body 1 and disposed in a lower region of the slider 34, while being disposed opposite to the inclined surface 40, the inclined surface and the reel The case where the elastic member 41 slidably contacted in a certain region on the front side of the main body 1 is attached to the lower end portion of the slider 34 is shown.

  The inclined surface 40 is inclined so as to slightly rise toward the moving direction (forward direction of the reel body 1 (the left direction shown in FIG. 8)) when the spool 4 moves forward. The elastic member 41 comes into slidable contact when moving to the front side of the reel body 1 from a certain position. When the elastic member 41 is in sliding contact with the inclined surface 40, the movement of the slider 34 is restricted by the elastic force of the elastic member 41. As a result, when the fishing rod is raised and the spool 4 is arranged at a position closer to the upper side than the fixed position, the slider 34 stops at that position.

  Note that the inclined surface 40 that restricts the movement of the slider 34 as described above does not hinder normal fishing line winding operation in consideration of the weight of the spool 4 and the power transmission efficiency of the spool reciprocating device 30. The inclination angle is selected so that the downward movement due to the weight of the spool 4 can be restricted. The elastic member 41 is elastic enough to restrict the downward movement due to the weight of the spool 4 without hindering a normal fishing line winding operation in consideration of the weight of the spool 4 and the power transmission efficiency of the spool reciprocating device 30. The one with power is selected.

  In FIG. 11, the sliding contact between the spool reciprocating device 30 and the elastic member 41 and the inclined surface 40 in a state where the elastic member 41 is in sliding contact with the inclined surface 40 and the movement of the slider 34 is restricted is released. The spool reciprocating device 30 in a state where the movement of the slider 34 is not regulated is shown.

  As described above, the inclined surface 40 is provided inside the housing disposed in the lower region of the slider 34, and the elastic member 41 slidably contacting the inclined surface 40 in a certain region is attached to the lower end portion of the slider 34. The movement of the slider 34 accompanying the movement of the spool 4 due to its own weight can be prevented, and the downward movement of the spool 4 unrelated to the operator's intention can be prevented. As a result, a situation in which the thread winding state of the winding body 4a of the spool 4 is deteriorated can be prevented, and the operability of the fishing spinning reel can be improved.

  In the above description, a general open-face type fishing spinning reel has been described. However, the present invention requires that the spool 4 be prevented from reciprocating back and forth when the rotor 3 is reversed. If so, the present invention can be applied to a closed face type reel, and the above-described excellent effects can be obtained.

  In particular, a rotor braking device is provided that applies a braking force to the rotor 3 that rotates in reverse according to the feeding of the fishing line by the fish, and the rotor 3 is intentionally rotated freely while the operator operates the rotor braking device. In the so-called lever brake reel disclosed in Patent Document 1 (Japanese Utility Model Publication No. 1-20858) of the above-described prior art, which enables communication with fish, in addition to the excellent effects described above, a further remarkable effect is achieved. Can be obtained.

  In other words, in the lever brake reel, the amount of fishing line depends on the operator's operation with respect to the rotor braking device. However, by applying the present invention, the vibration generated during the reverse rotation of the rotor 3 is eliminated. Therefore, it becomes possible to concentrate on the operation with respect to the rotor braking device, and it is possible to perform fishing while further enjoying the exchange with the fish.

  In the above description, the one-way clutch 17 (36) disposed in the spool reciprocating device 13 (30) is not limited to the above-described configuration, and a one-way clutch having another configuration is applied. Is possible. For example, a one-way clutch may be configured by combining a ratchet and a pawl, or may be configured by using a tightening force of a winding spring. Even in such a change, it is possible to obtain the same effect as that of the present embodiment described above.

  The present invention provides a spinning reel for fishing that can solve various problems caused by vibrations generated when the rotor rotates in reverse, and has excellent durability of the spool reciprocating device and freeness during reverse rotation of the rotor. It is provided and has industrial applicability.
