Description

  The present invention relates to an electric fishing reel provided with a drive motor that rotationally drives a spool that is rotatably supported by a reel body.

  In general, when fishing for a deep fish layer such as boat fishing, an electric fishing reel (hereinafter also referred to as an electric reel) is frequently used. This type of electric reel incorporates a so-called spool-in type in which a drive motor for winding and driving the spool is incorporated in the reel body, and the drive motor is housed in the internal space of the spool, and the drive motor is mounted on the reel body in front of the spool. A so-called spool-out type housed in a cylindrical motor case formed between side plates is known.

  In any type of electric reel, the drive motor has a structure in which a stator and an armature are accommodated in a cylindrical housing, and the motor motor is provided in the reel body with the drive motor unitized in this way. Is housed inside.

  By the way, such a drive motor may be deteriorated in performance due to heat generated by driving for a long time or high load winding drive, or the motor coil may be heated and burned.

For this reason, in order to improve the workability of motor replacement and periodic maintenance, the electric reel is designed so that the open / close lid can be opened and closed through the opening of the side plate of the reel body to improve the detachability of the motor. Is proposed in Patent Document 1.
Japanese Patent No. 3438212

  However, in the reel structure proposed in Patent Document 1, for example, when the motor burns out due to use under harsh conditions for a long time or does not move, or the performance is reduced, the motor is recovered in function. In this case, or when changing to a motor with different characteristics, it is very uneconomical because the entire motor unitized must be replaced or maintained.

  The present invention has been made paying attention to the above circumstances, and an object of the present invention is to provide an economical electric reel for fishing that can perform partial replacement or maintenance of the drive motor. .

  In order to achieve the above-described object, the present invention provides a fishing electric motor having a spool that is rotatably supported between side plates of a reel body, and a drive motor that is provided on the reel body and rotationally drives the spool. In the reel, a recess is formed in the reel body, and an armature is rotatably provided in the recess, and a magnet constituting a field is disposed on the inner surface of the recess facing the armature. By configuring the drive motor for rotationally driving the spool, and making the cover body covering the opening of the recess removable, the configuration of the drive motor such as the armature or magnet provided in the recess The feature is that parts can be exchanged.

  In the above configuration, the drive motor is not incorporated in the reel body as an integral unit as in the prior art, but the individual parts constituting the drive motor are individually disposed in the recess of the reel body, Since the cover that covers the opening of the recess can be attached and detached, for example, when the motor burns out due to use under severe conditions for a long time, or the performance deteriorates. When recovering the function of the motor, or when changing to a motor with different characteristics, it is possible to replace the minimum unit parts constituting the motor by simply removing the cover body, and to maintain a good motor. The function can be performed with the minimum necessary maintenance, and it is very economical.

  Further, in the above configuration, the constituent member of the reel body also serves as a part of the constituent member of the drive motor (the motor case of the conventional drive motor). That is, in the drive motor that rotates the spool, the magnet constituting the field member, which is a constituent member, is disposed on the inner surface of the recess formed in the reel body, and the armature is disposed in the recess. It has a structure. Therefore, at least the housing portion constituting the conventional drive motor is omitted, and accordingly, the reel body can be reduced in size while maintaining the output, or the output of the drive motor can be maintained while maintaining the size of the reel body. Can be improved. The recess formed in the reel body described above is a portion in which the magnet constituting the field is disposed on the inner surface, and the shape, size, and installation location can be appropriately modified. is there.

These outer plates 4a, 4b, and 4c are integrally formed individually, and are integrated as a whole, but the outer plates 4a, 4b, and 4c may be integrally formed as in the frame described above. However, it may be partially integrated and integrated as a whole. Moreover, the structure which exposed the said flame | frame partially may be sufficient.

  On one side plate (right side plate 4b) side that constitutes the reel body 5, a manual handle 6 that is wound up is provided, and a fishing line is placed between the left and right frames 3a and 3b that constitute the reel body 5. A spool 7 to be wound is rotatably supported. Further, a drive motor 30 configured as will be described later is installed on the front side of the spool 7, and the spool 7 is driven by a winding operation of the manual handle 6 and a rotational drive of the drive motor 30. It is rotationally driven in the direction of winding the fishing line via a driving force transmission mechanism described later.

  The spool 7 includes a fishing line winding body portion 7a around which a fishing line is wound, and flanges 7b and 7c for restricting the fishing line to be wound are formed at both ends thereof. The spool 7 is rotatably supported on the spool shaft 7s via a bearing, and is rotatably supported between the left and right side plates. Note that both ends of the spool shaft 7s are supported by the reel body 5 via bearings 10.

  A rotational driving force from the manual handle 6 and the driving motor 30 is input to the spool 7 via the driving power transmission mechanism 12. Hereinafter, a schematic configuration of the driving force transmission mechanism 12 will be described.

  The driving force transmission mechanism 12 of the present embodiment is configured to be distributed to the left frame 3a and the right frame 3b, and on the left frame 3a side, a first reduction mechanism 15 that decelerates the output of the drive motor 30, And the electric power transmission part 16 which transmits the rotational drive force decelerated by the 1st deceleration mechanism 15 to the spool shaft 7s is arrange | positioned. Further, on the right frame 3b side, the second reduction mechanism 17 that decelerates the rotational driving force of the spool shaft 7s and transmits it to the spool 7, and the rotational driving force of the driving shaft (handle shaft) 6a of the manual handle 6 are described above. A manual power transmission unit 18 that transmits to the spool 7 via the two speed reduction mechanism 17 is provided.

  In this case, the first speed reduction mechanism 15 is a well-known planetary gear mechanism installed between the output shaft (drive shaft) 31 of the drive motor 30 and the front frame 3c. And the planetary gear 15b that revolves around the sun gear 15a in a state of meshing with the sun gear 15a (rotating integrally with the output shaft 31) and the sun gear 15a. The pulley 16a rotates integrally with the output shaft 31, the pulley 16b rotates integrally with the spool shaft 7s, and the power transmission belt 16c wound around the pulleys 16a, 16b. The second speed reduction mechanism 17 is constituted by a known planetary gear mechanism installed between the spool shaft 7s and the spool 7, and the manual power transmission unit 18 is a drive mounted rotatably on the handle shaft 6a. A gear 18a and a pinion gear 18b meshing with the gear 18a are provided.

  A known drag mechanism 20 is disposed between the handle shaft 6a and the drive gear 18a. By rotating the drag knob 20a installed on the handle shaft 6a, a desired rotation of the spool 7 can be achieved. A braking force is applied. Further, the handle shaft 6a is provided with a reverse rotation prevention mechanism 6b, and when the drive motor 30 is driven to rotate, the manual handle 6 is prevented from interlocking rotation.

  The pinion gear 18b is rotatably disposed in an extending portion on the right side plate side of the spool shaft 7s and is movable in the axial direction, and a known clutch mechanism 22 is engaged with an outer peripheral portion thereof. . The pinion gear 18b is configured such that the clutch operating member 22a slides in the axial direction by the operation of an operation lever (not shown), whereby the pinion gear 18b is engaged / not engaged with the carrier of the second reduction gear mechanism (planetary gear mechanism). As a result, the transmission of the driving force to the spool 7 is succeeded and disengaged.

  Next, the configuration of the drive motor 30 will be described in detail.

  In the drive motor 30 according to the present invention, a recess is formed in a member constituting the reel body 5, a magnet constituting a field is removably disposed on the inner surface of the recess, and an armature is disposed inside the recess. It is configured to be detachable. That is, the recess formed in the reel body has a function as a casing in which a magnet for generating a field that is a constituent member of the drive motor is disposed.

  Specifically, in the present embodiment, a recess 32 that defines a cylindrical space is formed in the front frame 3c (the reel body located on the front side of the spool 7) constituting the reel body 5, A magnet 33 constituting a field is disposed on the inner surface 32a along the circumferential direction. In this case, the magnet 33 only needs to be detachably attached to the inner surface 32a, and may be locked by a holding means, for example. Moreover, the magnet 33 may be arrange | positioned at predetermined intervals along the circumferential direction. Further, the magnet 33 has a cylindrical yoke (a yoke) 33a that forms a magnetic circuit on its outer side to prevent leakage of magnetic force, and functions as such a yoke on the frame 3c. May be given.

  The front frame 3c in which the recess 32 is formed has an opening on the right side plate side as it is, and a bottom wall 3d is formed on the left side plate side, and the drive shaft 31 is interposed via a bearing 34 at the center of the bottom wall 3d. Is supported rotatably.

  The drive shaft 31 is mounted with an armature 35 (coil facing the magnet 33), which is a constituent member of the drive motor 30, facing the magnet 33 attached to the inner surface 32a of the recess 32. A commutator 37 that supplies current to the armature 35 is mounted on the right side plate side of the armature 35 in the axial direction.

  The commutator 37 protrudes from the opening on the right side plate side of the front frame 3c (opening of the recess 32), and this opening portion is fixed by a fixing screw 39 screwed to the right frame 3b in the vicinity of the front frame 3c. An end cover 40 as a cover body is attached to the front frame 3c so as to be detachable. The end cover 40 is configured as a single unit in advance (see, for example, FIG. 3), and on the radially inner side, a brush 41 that contacts the commutator 37 and flows current and holds the brush. A brush holder 42 is incorporated and fixed to the front frame 3c with screws 39. A terminal 43 is integrally incorporated in the brush holder 42 and is connected to an external power source via a lead wire 44.

  The end cover 40 includes a holding body 48 that holds a one-way clutch 46 that rotatably supports the drive shaft 31 and a bearing 47 that rotatably supports the drive shaft in order from the inner side in the axial direction. It is. In this case, the one-way clutch 46 moves the drive shaft 31 in one direction so as not to idle when the manual handle 6 is wound up and to transmit power to the spool 7 side when the drive motor is driven. It is allowed to rotate only.

  The first speed reduction mechanism 15 constituted by the planetary gear mechanism described above is installed on the outer side in the axial direction with respect to the bottom wall 3d, and is closed by an end cover 50 attached to the front frame 3c. .

  As described above, the drive motor 30 that rotationally drives the spool 7 is not incorporated in the reel body 5 as an integral unit as in the prior art, but constitutes a field that is a constituent member thereof. The magnet 33 is detachably disposed on the inner surface of the recess 32 formed in the reel body 5, and the armature 35 is detachably disposed in the recess 32. The end cover 40 that covers the opening of the recess 32 is detachable. Therefore, for example, when the motor burns out due to use under severe conditions for a long time, or when the motor recovers its function due to reduced performance, or when it is changed to a motor with different characteristics 3 and FIG. 4, the minimum unit parts 33 and 35 constituting the drive motor 30 can be individually removed and replaced by simply removing the end cover 40 as shown in FIGS. Since the motor maintenance function can be performed with the minimum necessary maintenance, it is very economical.

  In the configuration of the present embodiment, the magnet 33 and the armature 35 can be taken out from the reel body 5 side by removing the end cover 40 after removing the entire side plate 4b (see FIG. 2). The end cover 40 may be exposed to the outside without being covered with the side plate 4b, and the end cover 40 may be directly attached / detached from the outside without removing the side plate 4b. This makes it easier to replace and maintain the components of the drive motor 30. Alternatively, an opening / closing lid may be separately provided on the outer plate 4b, and the end cover 40 may be accessed by removing the opening / closing lid.

  In the present embodiment, the constituent member (frame 3) of the reel body 5 is a part of the constituent member of the drive motor 30 (a casing that generates a field). For this reason, the housing part which comprises the drive motor used for the conventional electric reel is abbreviate | omitted, and the reel main body 5 can be reduced in size while maintaining the output, or the size of the reel main body 5 is maintained, The armature 35 constituting the drive motor 30 can be increased in size to improve the output. Further, since the casing is integrated with the frame, a lightweight and compact electric reel can be obtained, and the operability and handling at the fishing spot can be improved.

  In addition, the conventional electric reel has a so-called dual structure because the drive motor having the housing is housed in a case formed in the reel body. However, by adopting the structure as described above, The drive motor part has a single structure, and the area that directly contacts the outside air of the part that acts to dissipate heat (the frame part that constitutes the motor housing) can be increased, so that the heat dissipation can be improved. As a result, problems due to heat accumulation can be avoided, and the durability and winding efficiency of the drive motor can be improved. In particular, in the spool-out type electric reel, it becomes easy to configure the portion where the recess that becomes the housing is directly in contact with the outside air, and it is possible to improve the heat dissipation and to ensure the trouble due to heat generation. It becomes possible to prevent.

  In addition, the above-mentioned recess 32 should just be a part in which the magnet 33 which comprises a field magnet is attached to the inner surface, About the shape, a magnitude | size, and an installation location, it can change suitably. It is. In addition to the above-described frame, the portion forming the recess may be formed integrally with the outer plate, or may be formed over the frame 3 and the outer plate 4.

  In the above-described configuration, it is preferable that the seal member 52 is installed in various places on the reel body 5 so that the water tightness of the drive motor 30 can be improved. Such a seal member 52 can be constituted by, for example, an O-ring or a cover body made of a rubber-based or silicon-based material. In the present embodiment, the seal member 52 is provided between the end cover 40 and the front frame 3c, between the end cover 40 and the lead wire 44, between the end cover 50 and the front frame 3c, and between the end cover. 50 and the drive shaft 31.

  Such a seal member 52 is disposed at an appropriate position so that the inside of the recess in which the armature portion of the drive motor 30 is installed can be kept watertight, and the formation position, size, shape, and drive of the recess It is appropriately modified according to the installation mode of the constituent members of the motor.

  Next, a second embodiment of the present invention will be described with reference to FIGS. Among these drawings, FIG. 5 is a sectional view showing the internal structure from the rear side, and FIG. 6 is an exploded view showing the configuration of the drive motor portion.

  In the above-described embodiment, the drive motor 30 is disposed on the front side of the spool 7 of the reel body 5, but in the present embodiment, the drive motor 30 is disposed inside the spool 7 (so-called spool-in type). ). In this figure, parts having the same functions as those in the above-described embodiment are given the same reference numerals.

  In the present embodiment, a cylindrical protrusion 3e that protrudes toward the right side plate is formed integrally with the left frame 3a of the frame 3 constituting the reel body, and a recess 32 is formed in the protrusion. Forming. The projecting portion 3e is set to a size that can be disposed in an internal space formed in the spool 7 around which the fishing line is wound, and a magnet 33 that constitutes a field is provided on the inner surface 32a of the recess 32 in the circumferential direction. It is arrange | positioned so that removal is possible. In this case, the magnet 33 only needs to be detachably attached to the inner surface 32a. For example, the magnet 33 may be locked by holding means, and is disposed at a predetermined interval along the circumferential direction. May be. Further, the magnet 33 may have a yoke (yoke) constituting a magnetic circuit attached to the outside thereof, or the protruding portion 3e may have a function as such a yoke.

  The protrusion 3e in which the recess 32 is formed has an opening on the left side plate as it is, and a bottom wall 3f is formed on the right side plate side, and a drive motor 30 via a bearing 34 at the center of the bottom wall 3f. The drive shaft 31 is rotatably supported.

  An armature 35 (coil facing the magnet 33), which is a component of the drive motor 30, can be removed from the drive shaft 31 so as to face the magnet 33 detachably disposed on the inner surface 32 a of the recess 32. A commutator 37 that supplies current to the armature 35 is attached to the outer side of the armature 35 in the axial direction. In the left frame 3a on which the protruding portion 3e is formed, a brush 41 that flows in contact with the commutator 37 and a brush holder 42 that holds the brush are incorporated and fixed by screws 39a. A terminal 43 is integrally incorporated in the brush holder 42 and is connected to an external power source via a lead wire 44.

  An end cover 40 is attached to the opening of the protrusion 3e so as to be detachable from the protrusion 3e by a fixing screw 39 screwed to the left frame 3a. The end cover 40 is configured in advance as one unit, and in order from the inner side in the axial direction, a one-way clutch 46 that rotatably supports the drive shaft 31 and a bearing 47 that rotatably supports the drive shaft 31. And are incorporated. In this case, the one-way clutch 46 moves the drive shaft 31 in one direction so as not to idle when the manual handle 6 is wound up and to transmit power to the spool 7 side when the drive motor is driven. It is allowed to rotate only.

  A known driving force transmission mechanism 60 having a speed reduction mechanism 15 (planetary gear mechanism) is disposed between the spool 7 and the drive shaft 31 on the right side plate side of the protrusion 3e. A rotational driving force from the manual handle 6 and the drive motor 30 can be input to the spool 7.

  Therefore, also in this embodiment, the minimum unit parts 33 and 35 constituting the drive motor 30 can be individually removed and replaced by simply removing the end cover 40, and the same action as in the first embodiment. An effect can be obtained. Particularly, in an electric reel in which such a drive motor 30 is a spool-in type, the diameter of the fishing line winding body portion 7a of the spool can be reduced because the motor housing portion has a single structure. Although it is a reel main body, it becomes possible to employ | adopt the spool which increased thread winding capacity.

  As in the above-described embodiment, the installation portion of the drive motor 30 can be appropriately modified, and the configuration of the reel body can be appropriately modified accordingly.

  7 and 8 show a third embodiment of the present invention. Note that this embodiment is a modification of the above-described first embodiment, and therefore, the same reference numerals are given to components common to the first embodiment, and detailed description thereof is omitted.

  In the first embodiment, when the end cover 40 is removed and the minimum unit parts 33 and 35 constituting the drive motor 30 are individually removed, the sun gear 15a and the bearing 34 of the speed reduction mechanism (planetary gear mechanism) 15 are In this embodiment, the bearing 34 and the sun gear 15a are integrated with the output shaft 31. If the end cover 40 is removed, the bearing 34 and the sun gear 15a are output. It can be removed from the reel body 5 side together with the shaft 31.

  Specifically, in the present embodiment, the sun gear 15a and the bearing 34 are attached to the output shaft 31 so as not to be detached, and the output shaft 31 having the armature 35, the bearing 34, and the sun gear 15a are integrated. The motor core unit is configured to be removable from the recess 32. Further, the outer diameter A of the sun gear 15a is set smaller than the outer diameter B of the bearing 34 so that the bearing 34 and the sun gear 15a can be pulled out together with the output shaft 31 from the bottom wall 3d of the front frame 3c. .

  As a method for preventing the sun gear 15a and the bearing 34 from being attached to the output shaft 31, for example, as shown in FIG. Then, the sun gear 15a is fixed to the output shaft 31 by caulking (the caulking portion 120 is shown in FIG. 8B) or the sun gear 15a is connected to the output shaft as shown in FIG. 8C. It can be considered that the outer periphery of 31 is fixed by press fitting or adhesion. Needless to say, the bearing 34 can be attached to the bearing 34 by the same method. Further, in the case of caulking and fixing, the non-circular fitting portion between the sun gear 15a (or the bearing 34) and the output shaft 31 necessary for preventing rotation is suppressed to the minimum necessary, and a large number of circular fitting portions are taken. Thus, it is desirable to improve the concentricity of the sun gear 15a (or the bearing 34) and the output shaft 31.

  As described above, when the bearing 34 and the sun gear 15a are configured to be detachable from the recess 32 integrally with the output shaft 31, that is, when the sun gear 15a and the bearing 34 are attached to the output shaft 31 to prevent the planetary gears from being detached. Generation of backlash to the output shaft 31 of the sun gear 15a meshing with the sun gear 15b can be prevented, and generation of noise during meshing of the sun gear 15a and the planetary gear 15b can be prevented. That is, when the sun gear 15a is detachably fitted to the output shaft 31 (in the case of the first embodiment), play occurs between the sun gear 15a and the output shaft 31 ( Although it is necessary to fit and detach, there is a concern that abnormal noise may occur during meshing because there is of course a slight clearance between the sun gear 15a and the output shaft 31. According to the configuration of the form, such a problem does not occur. Further, according to the present embodiment, the sun gear 15a and the bearing 34 can be assembled together with the output shaft 31 (including the armature 35) on the reel body 5 side as a motor core unit. After setting, there will be no restrictions on the order of installation, such as installing sun gears, and workability and maintenance will be improved.

  FIG. 9 shows a fourth embodiment of the present invention. Note that this embodiment is a modification of the above-described second embodiment, and therefore, the same reference numerals are given to components common to the second embodiment, and detailed description thereof is omitted.

  In the second embodiment, the sun gear 15a and the bearing 34 of the speed reduction mechanism (planetary gear mechanism) 15 are removed when the end cover 40 is removed and the minimum unit parts 33 and 35 constituting the drive motor 30 are individually removed. In this embodiment, the bearing 34 and the sun gear 15a are integrated with the output shaft 31. If the end cover 40 is removed, the bearing 34 and the sun gear 15a are output. It can be removed from the reel body 5 side together with the shaft 31. The configuration necessary to realize such a structure is the same as that of the third embodiment, and therefore detailed description thereof is omitted. Even in such a configuration, the same effects as those of the third embodiment can be obtained.

Yes. In this case, the engaging portion 7h only needs to have a function as a power transmission portion so that the clutch actuating member 141 and the spool 7 rotate integrally. It consists of parts.

  A rotational driving force from the manual handle 6 and the drive motor 30 is input to the spool 7 via the power transmission mechanism 12. In this case, the power transmission mechanism 12 includes a planetary gear mechanism 15 that decelerates the rotational drive of the drive motor 30, and a clutch mechanism 22 that switches power transmission in the power transmission mechanism 12 between a power transmission state and a power cutoff state. It has become. Hereinafter, configurations of the power transmission mechanism 12, the planetary gear mechanism 15, and the clutch mechanism 22 will be described.

And a first planetary gear 132 and a second planetary gear 133 that mesh with each of them. In this case, the first sun gear 130 is fixed to the output shaft 31, and the second sun gear 131 is free to rotate. Each planetary gear 132, 133 meshes with an internal tooth 135a formed on a first rotating body 135 rotatably supported on the right frame 3b. The first carrier 132a that supports the first planetary gear 132 is connected and fixed to the second sun gear 131, and the second carrier 133a that supports the second planetary gear 133 protrudes toward the right outer plate. The support shaft 21 is integrated and fixed to the connection gear 120.

  The handle shaft 6a is provided with a reverse rotation prevention mechanism 6b so as to prevent the manual handle 6 from rotating when the drive motor 30 is driven to rotate. In addition, although the reverse rotation prevention mechanism 6b of this embodiment is comprised as a reverse rotation prevention ratchet with which the handle shaft 6a is mounted | worn, you may comprise by a one-way clutch. A one-way clutch is provided on the left side plate-side protruding portion of the output shaft 31 of the drive motor 30 so as not to idle when the manual handle 6 is wound up and to transmit power to the spool 7 side. 46 is attached.

  The rotational driving force of the first rotating body 135 meshing with the planetary gear mechanism 15 is transmitted coaxially to the spool 7 and transmitted to the second rotating body 139 that is rotatably supported by the right frame 3b that is a reel body. Thus, the transmission of the rotational driving force between the two is performed via a power transmission belt 150. That is, the outer peripheral surfaces of the first rotating body 135 and the second rotating body 139 are formed with irregularities into which teeth (concave portions) continuously formed inside the belt 150 are fitted, and the belt 150 is formed in this portion. It is comprised so that power may be transmitted by winding.

  The second rotating body 139 in the present embodiment has a circular recess 139a formed on the spool side, and a bearing 139b installed between the inner surface of the peripheral wall and the cylindrical portion 3g formed to protrude from the right frame 3b. Is rotatably supported by the right frame 3b. In other words, the engaging portion 141a of the clutch operating member 141 of the clutch mechanism 22 is arranged in a superposed manner on the radially inner side of the bearing 139b serving as the support portion of the second rotating body 139.

  As a result, the spool shaft direction having the clutch engaging portion can be shortened, and the reel body 5 can be reduced in size and size. It should be noted that at least a part of the above-described engaging portion 141a is superposed on the bearing 139b. That is, a configuration may be adopted in which a recess is formed in the second rotating body 139 and at least a part of the engaging portion 141a is located in this portion.

  In the present embodiment, a support case (set plate) 80 attached to the right frame 3b is installed between the right frame 3b and the right outer plate 4b. The power transmission mechanism 12 is housed inside the support case 80, and preferably the planetary gear mechanism 15 (planetary gears 132 and 133), which is a member having a large driving sound, and the first rotation in which these mesh with each other. What is necessary is just to accommodate the body 135, and further, the second rotating body 139 and the belt 150 are accommodated. Therefore, the first rotating body 135 is rotatably supported via the bearings 136a and 136b in the accommodation space between the support case 80 and the right frame 3b.

  The clutch mechanism 22 is coaxial with the spool shaft 7s and has a support shaft 140 disposed between the right frame 3b and the right side plate 4b. The clutch mechanism 22 surrounds the support shaft 140 via a pair of bearings 142 and the right frame 3b and A clutch actuating member 141 that is rotatable between the right side plates 4b and is movable in the axial direction, an actuating plate 144 that engages with the clutch actuating member 141, and a clutch actuating member 141 that engages with the actuating plate 144. And a control lever 146 provided between the side plates 4a and 4b behind the spool 7 for driving the clutch switching member 145 so as to be movable up and down. Note that a clutch operating member 141 is movable in the axial direction and is non-rotatably fitted to the central portion of the second rotating body 139.

  On the spool side of the clutch actuating member 141, an engaging portion 141a that fits into a locking portion 7h having a non-circular cross section formed on the spool shaft 7s is formed. The engaging portion 141a and the locking portion 7h are engageable and disengageable and have a non-circular cross-sectional fitting relationship as described above, and when the both are fitted, the clutch operating member 141 is the second rotating body. By being driven to rotate by 139, the spool 7 rotates integrally with the spool shaft 7s.

  The operating plate 144 is engaged with a circumferential groove 141c disposed outside the support plate 80 on the outer periphery of the clutch operating member 141, and the clutch operating member 141 is constantly biased toward the spool side. In this state, the engaging portion 141a of the clutch actuating member 141 is fitted to the engaging portion 7h of the spool shaft 7s, and is in a power transmission state (clutch ON). When the operation lever 146 is moved, the clutch operating member 141 is slid and driven toward the right outer side plate 4b through the clutch switching member 145 and the operating plate 144. In this state, the engaging portion 141a of the clutch operating member 141 is disengaged from the locking portion 7h, and the power transmission is cut off (clutch OFF).

  The return from the clutch OFF state to the clutch ON state is performed by a winding operation of the manual handle 6 or a movement operation of the operation lever 146 by a known return mechanism.

  Next, the power transmission path of the driving force of the manual handle 6 and the drive motor 30 by the power transmission mechanism 12 will be described.

  When the manual handle 6 is wound up, the rotational driving force is input to the planetary gear mechanism 15 via the driving gear 18a, the connecting gear 120, and the support shaft 21 (second carrier 133a). The rotational driving force input to the planetary gear mechanism 15 rotates while revolving around the first sun gear 130 that is fixed by the second sun gear 131, the first carrier 132a, and the one-way clutch 46. It is transmitted to the first rotating body 135 through the one planetary gear 132 in a decelerated state.

  The rotating direction of the first rotating body 135 is counterclockwise, and the second rotating body 139 is similarly rotated counterclockwise via the belt 150. Thus, the spool 7 is rotationally driven in the direction of winding the fishing line via the clutch operating member 141 that is prevented from rotating around the second rotating body 139.

  On the other hand, when the drive motor 30 is rotationally driven, the first sun gear 130 is rotationally driven in the clockwise direction, and the first carrier 132a is rotationally driven in the clockwise direction by this rotational driving force. At this time, the second sun gear 131 is also rotated in the clockwise direction, and the second carrier 133a is also driven to rotate in the clockwise direction, and the second carrier 133a is driven via the connecting gear 120. The reverse rotation preventing mechanism 6b attached to the gear 18a cannot rotate in the clockwise direction, and as a result, the second planetary gear 133 rotates in the counterclockwise direction. Accordingly, the first rotating body 135 is rotationally driven in the counterclockwise direction while being decelerated by the rotation of each second planetary gear 133.

  Then, the counterclockwise rotation of the first rotating body 135 rotates the second rotating body 139 counterclockwise via the belt 150 as in the case of the manual handle 6 described above, and the spool 7 It is driven to rotate in the direction of winding the fishing line through a clutch operating member 141 that is prevented from rotating around the second rotating body 139.

  Further, in such a structure (a structure in which the left and right of the built-in motor structure of the first embodiment are reversed), the structure of the third embodiment described above is adopted as shown in FIG. That is, as shown in FIG. 11, by simply removing the end cover 40, not only can the minimum unit parts 33 and 35 constituting the drive motor 30 be individually removed and replaced, but also the bearing 34 and the sun gear. 130 is integrated with the output shaft 31, and the bearing 34 and the sun gear 130 can be removed together with the output shaft 31 from the reel body 5 side by removing the end cover 40. Therefore, the same effect as the third embodiment can be obtained. In the present embodiment, as clearly shown in FIG. 11B, the opening of the front frame 3c located on the speed reduction mechanism 15 side (the opening on the side where the output shaft 31 is attached to and detached from the speed reduction mechanism 15). ) Is provided with a waterproof packing 99 for keeping the recess 32 watertight with respect to the outside. The waterproof packing 99 is left on the reel body 5 side as shown in FIG. 11B when the end cover 40 is removed and the minimum unit parts 33 and 35 constituting the drive motor 30 are individually removed. Although it may be in a state, it may be located between the bearing 34 on the output shaft 31 and the sun gear 130 so as to be integrated with the output shaft 31 and removed from the reel body 5 side.

  As mentioned above, although several embodiment of this invention was described, this invention is not limited to the structure of above-described embodiment, It can change variously. For example, the above-described driving force transmission mechanisms 12 and 60 can be variously modified, such as a power transmission structure using a gear train, or a driving force transmission system concentrated on one side plate. In addition, the drive motor need only have a magnet for generating a field disposed in a recess formed in the reel body, and the configuration and arrangement of other components can be modified as appropriate. It is. Moreover, about the structure of the drag mechanism 20 or the clutch mechanism 22, and its arrangement | positioning aspect, it can change suitably.
