Modes for Carrying Out the Invention

[0010] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0011] <1. First Embodiment> [Overall Configuration of the Reel Device 1-1] FIG. 1 is a cross-sectional view schematically showing a reel device 1 according to the first embodiment. As shown in this figure, the reel device 1 according to the first embodiment is a bait reel for fishing and is an electric reel capable of electrically winding a fishing line by a motor. Specifically, the reel device 1 includes a handle 2 to which a rotational force is input by a user, a manual shaft gear 3 that shifts the rotational force input to the handle 2, a spool 6 around which the fishing line is wound, a motor 7, an electric shaft gear 8 that shifts the rotational force by the motor 7, and an adjustment gear 9. These handle 2, manual shaft gear 3, spool 6, motor 7, electric shaft gear 8, adjustment gear 9, etc. are supported by a frame (body) 10.

[0012] [Handle 1-2] The handle 2 has a grip 21 held by the user and an arm 22 provided with the grip 21 at one end and connected to the manual shaft gear 3 at the other end. The arm 22 is supported by the frame 10 so as to be rotatable around a first central axis Ax1 via a one-way clutch (not shown). The one-way clutch rotates the handle 2 only in one direction corresponding to the direction in which the spool 6 winds up the fishing line. In the following description, the direction along the central axis is referred to as the "axial direction", the direction perpendicular to the central axis is referred to as the "radial direction", and the rotational direction around the central axis is referred to as the "circumferential direction". The "central axis" is the central axis of each component and is any one of the first central axis Ax1 to the third central axis Ax3. Also, among the axial directions, the side where the handle 2 is disposed (the right side in FIG. 1) is referred to as the "input side", and the opposite side (the left side in FIG. 1) is referred to as the "anti-input side".

[0013] [Spool 1-3] The spool 6 is formed in a substantially cylindrical shape along the axial direction and is a thread winding portion around which a fishing line (line) is wound on the outer peripheral surface. The spool 6 is supported by the frame 10 so as to be rotatable around a second central axis Ax2 coaxial with the first central axis Ax1 via an integrally formed spool shaft 61, and winds up and pays out the fishing line by its rotation. In addition, a brake for applying a braking force to the spool 6 may be provided. The brake applies a braking force corresponding to the rotational speed of the spool 6 to suppress backlash and stabilize casting. As such a brake, for example, a centrifugal brake, a magnet brake, or other conventionally known techniques can be applied.

[0014] [1-4 Manual shaft gear (second speed change mechanism)] FIG. 2 is a diagram for explaining the schematic structure of the manual shaft gear 3, and is a cross-sectional view of the manual shaft gear 3 (magnetic modulation gear) taken along line II-II in FIG. 1. As shown in FIGS. 1 and 2, the manual shaft gear 3 is an example of the second speed change mechanism according to the present invention, and is arranged between the handle 2 and the spool 6, and can transmit the rotational force input to the handle 2 after speed change to the spool 6. The manual shaft gear 3 of the present embodiment is a magnetic modulation gear, and includes an outer pole member 31, an inner pole member 32, and a pole piece member 33.

[0015] The outer pole member 31 is an input shaft in the present embodiment, and the arm 22 of the handle 2 is connected to the end portion on the input side in the axial direction, and the rotational force is input from the handle 2. The outer pole member 31 is formed in a substantially cylindrical shape centered on the first central axis Ax1 and has an outer pole magnet 31a. The outer pole magnet 31a is a permanent magnet such as a neodymium magnet, and a plurality of magnets with different polarities are alternately arranged in the circumferential direction. Note that the outer pole member 31 may have a yoke or the like for supporting the outer pole magnet 31a. Further, the outer pole magnet 31a may be an integral ring shape, or may be a shape in which divided ones are arranged in the circumferential direction.

[0016] The inner pole member 32 is the output shaft in this embodiment, and the spool 6 is connected to the anti-input side thereof. The inner pole member 32 is concentrically arranged on the inner diameter side of the outer pole member 31 and has a shaft 32a and inner pole magnets 32b. The shaft 32a is rotatably supported around the first central axis Ax1. The inner pole magnets 32b are permanent magnets such as neodymium magnets, for example, have fewer pole numbers than the outer pole magnets 31a of the outer pole member 31, and a plurality of them with different polarities are alternately arranged in the circumferential direction and are attached to the outer peripheral surface of the shaft 32a. Note that the inner pole magnets 32b may be in an integral ring shape or may be in a shape such as a divided one arranged in the circumferential direction.

[0017] The shaft 32a is coaxially connected to the spool shaft 61 of the spool 6 via the first clutch 51. The first clutch 51 switches the shaft 32a and the spool shaft 61 between a connected state in which rotational force is transmitted and a separated state in which it is not transmitted by operating a clutch lever (not shown).

[0018] The pole piece member 33 is formed in a substantially cylindrical shape and is concentrically arranged with the outer pole member 31 and the inner pole member 32 at a radial position therebetween. The axial end portions of the pole piece member 33 are fixed to the frame (body) 10. The pole piece member 33 has pole pieces (pole pieces) 33a arranged on the outer diameter side of the inner pole magnets 32b. The pole pieces 33a are composed of laminated steel plates, and a plurality of them are arranged at predetermined intervals in the circumferential direction. The number of the pole pieces 33a is the outer pole logarithm (the pole logarithm of the outer pole magnets 31a) ± the inner pole logarithm (the pole logarithm of the inner pole magnets 32b), and generally is the outer pole logarithm + the inner pole logarithm. The space between two adjacent pole pieces 33a in the circumferential direction may be connected by a thin connecting portion, may be connected by a non-magnetic body, or may not be connected. Note that FIG. 2 shows an example in which two adjacent pole pieces 33a are not connected. Also, the pole pieces 33a do not necessarily have to be composed of laminated steel plates as long as they are magnetic bodies, and may be blocks of steel materials (such as SS materials and SPCC materials) as long as they only operate.

[0019] In the manual shaft gear 3 having the above configuration, when rotation is input to the outer pole member 31, the spatial magnetic flux waveform of the outer pole magnet 31a of the outer pole member 31 is modulated to the same frequency as the inner pole magnet 32b of the inner pole member 32 by the pole piece 33a of the pole piece member 33, and torque is transmitted to the inner pole member 32 using the magnetic force between the pole piece 33a and the inner pole magnet 32b. That is, in the manual shaft gear 3, power is transmitted from the outer pole member 31 to the inner pole member 32 by the modulated magnetic flux. At this time, the speed ratio is the outer pole pole logarithm / the inner pole pole logarithm (the rotation is in the opposite direction). Note that the manual shaft gear 3 (magnetic modulation gear) can function as a differential gear that, for example, uses a pole piece member as a differential shaft and absorbs the difference between two rotational inputs to output a single rotation.

[0020] [1-5 Motor] As shown in FIG. 1, the motor 7 is arranged at an axial position approximately the same as that of the spool 6, and outputs a rotational force to a motor shaft 71 along a third central axis Ax3 parallel to the first central axis Ax1. The motor shaft 71 is connected to the shaft 32a of the manual shaft gear 3 via a connection mechanism 75. The connection mechanism 75 transmits the rotational force of the motor 7 to the spool 6. The connection mechanism 75 of the present embodiment includes two pulleys 76 fixed on two shafts for transmitting rotational force, and a belt 77 stretched between the two pulleys 76. However, the connection mechanism 75 does not have to be a belt transmission mechanism as long as it can transmit rotational force, and may be, for example, a gear mechanism in which spur gears are meshed.

[0021] [1-6 Electric Shaft Gear (First Speed Change Mechanism)] The electric shaft gear 8 is an example of the first speed change mechanism according to the present invention, and is arranged between the motor 7 and the connection mechanism 75, and can change the rotational force of the motor 7 and transmit it to the spool 6. The electric shaft gear 8 of the present embodiment is a planetary gear mechanism. However, the electric shaft gear 8 may be a mechanical speed change mechanism other than the planetary gear mechanism.

[0022] The electric shaft gear 8 is connected to the coupling mechanism 75 via the second clutch 52. The second clutch 52 switches, by operating a clutch lever (not shown), the electric shaft gear 8 (and thus the motor 7) and the coupling mechanism 75 between a connected state in which rotational force is transmitted and a separated state in which transmission does not occur.

[0023] [1-7 Adjusting gear (differential gear)] The adjusting gear 9 is a differential gear (differential transmission mechanism) that absorbs the difference in rotational output between the manual shaft gear 3 and the electric shaft gear 8. The adjusting gear 9 of the present embodiment is a planetary gear mechanism. However, the adjusting gear 9 may be a differential transmission mechanism other than a planetary gear mechanism.

[0024] [1-8 Operation of the reel device] ·During manual winding In the reel device 1, when manually winding the fishing line, the user sets the first clutch 51 to the connected state and the second clutch 52 to the separated state by performing a predetermined lever operation or the like. In this state, when the user manually rotates the handle 2, the outer pole member 31 of the manual shaft gear 3 connected to the handle 2 also rotates in the same direction. When the outer pole member 31 rotates, the spatial magnetic flux waveform of the outer pole magnet 31a is modulated by the pole piece 33a of the pole piece member 33, and rotational torque (rotational force) is transmitted to the inner pole member 32 (the rotation is in the reverse direction). At this time, the speed ratio is the number of outer pole pairs / the number of inner pole pairs, and in this embodiment, the speed is increased. Then, the spool 6 connected to the inner pole member 32 via the first clutch 51 also rotates in the same direction as the inner pole member 32, and the fishing line is wound up at an increased speed.

[0025] At this time, when the fishing line is forcibly pulled out from the spool 6 due to a strong pull of the fish or the like, the spool 6 rotates in the direction opposite to that during line winding, and the inner pole member 32 connected to the spool 6 also rotates in the same direction. As the inner pole member 32 rotates, the outer pole member 31 also tries to rotate in the direction opposite to that during line winding, but the rotation of the handle 2 is restricted by, for example, a one-way clutch, and the outer pole member 31 connected to the handle 2 cannot rotate either. As a result, the inner pole member 32 gets out of adjustment and rotates independently from the outer pole member 31, and the drag is started. In this way, the fishing line is pulled out from the spool 6 and the drag is performed. In addition, at least one of the magnetic pole piece member 33, the outer pole member 31, and the inner pole member 32 may be configured to be axially movable so that the out-of-adjustment torque and thus the drag force (the tension of the fishing line when the drag occurs) can be adjusted. In terms of generating a larger torque change with a smaller movement amount, it is more preferable to move the magnetic pole piece member 33.

[0026] ·When electrically winding up When the fishing line is wound up by the motor 7, the user connects both the first clutch 51 and the second clutch 52 in a connected state by a predetermined lever operation or the like. In this state, for example, when the motor 7 is driven by a predetermined lever operation or the like, the rotational force output from the motor 7 is decelerated, for example, through the electric shaft gear 8, and the spool 6 is rotated through the connection mechanism 75. As a result, the fishing line is wound up with the decelerated rotation. In addition, the difference between the rotational force (rotational speed) input from the motor 7 to the spool shaft 61 through the connection mechanism 75 and the rotational force of the inner pole member 32 of the manual shaft gear 3 is absorbed by the adjustment gear 9.

[0027] ·When releasing the line When releasing the fishing line from the spool 6, the user separates both the first clutch 51 and the second clutch 52 in a separated state by a predetermined lever operation or the like. As a result, for example, as the fishing line is pulled out, the spool 6 rotates in the direction opposite to that during line winding, and the fishing line is released. In addition, the release of the fishing line is performed in the same manner as in this embodiment in each of the following embodiments.

[0028] [1-9 Technical effects of this embodiment] As described above, according to the first embodiment, the rotational force input to the handle 2 manually by the user is transmitted to the spool 6 after being shifted by magnetic modulation in the manual shaft gear 3. Thereby, since power (torque) can be transmitted from the handle 2 to the spool 6 in a non-contact manner, power loss at the contact portion generated in the mechanical (contact type) torque transmission mechanism, mechanical noise (gear meshing noise), and changes in characteristics due to the contact state can be suppressed. In addition, the amount of maintenance that has been conventionally required to suppress these can also be significantly reduced.

[0029] Also, by the out-of-phase adjustment between the outer pole member 31 connected to the handle 2 and the inner pole member 32 connected to the spool 6, dragging (obtaining a torque limit effect) can be achieved. Thereby, compared with the frictional drag, the change in the drag force can be suppressed. Generally, factors causing fluctuations in the drag force include aging changes and environmental dependence, as well as the rotational speed of the spool 6, frictional heat due to the continuous pulling out of the fishing line L, and the like. In addition, in the case of a bait reel, it is said that the position of the drag is far from the spool axis due to the structure, and the drag operation performance is lower than that of a spinning reel. In this regard, according to this embodiment, by the out-of-phase adjustment between the outer pole member 31 and the inner pole member 32, the drag can be preferably made to function.

[0030] <2. Second Embodiment> [2-1 Configuration of the Reel Device] FIG. 3 is a cross-sectional view schematically showing a reel device 1B according to the second embodiment, and FIG. 4 is a diagram showing the basic configuration and its features of each embodiment. In the following embodiments, the same reference numerals are given to the same components as those in the above embodiment, and the description thereof is omitted. Also, hereinafter, when identifying the reference numerals of the respective components in the second to fifth embodiments, capital letters "B" to "E" are appended to the end, respectively.

[0031] As shown in FIGS. 3 and 4, the reel device 1B according to the second embodiment is different from the reel device 1 according to the first embodiment mainly in that the manual shaft gear 3B is a gear mechanism with spur gears and the electric shaft gear 8B is a magnetic modulation gear.

[0032] The manual shaft gear 3B is a gear mechanism in which a plurality of spur gears are externally meshed, and transmits the rotational force input to the handle 2 to the spool 6 side at a predetermined gear ratio.

[0033] The electric shaft gear 8B is a magnetic modulation gear similar to the manual shaft gear 3 in the first embodiment, and includes an outer pole member 81B, an inner pole member 82B, and a pole piece member 83B (see FIG. 2). These have the same basic structure as the outer pole member 31, the inner pole member 32, and the pole piece member 33 in the manual shaft gear 3 of the first embodiment. The outer pole member 81B is fixed to the frame 10. The inner pole member 82B is connected to the motor shaft 71, and a rotational force is input from the motor shaft 71. An output shaft 84B is fixed to the pole piece member 83B. The output shaft 84B is connected to the spool shaft 61 of the spool 6 via a coupling mechanism 75. The coupling mechanism 75 is connected to the spool 6 via a second clutch 52B. The second clutch 52B switches the coupling mechanism 75 (and thus the motor 7) and the spool 6 between a connected state in which a rotational force is transmitted and a separated state in which the rotational force is not transmitted by operating a clutch lever (not shown). Note that in the electric shaft gear 8B, the pole piece member 83B may be fixed to the frame 10 and the outer pole member 81B may be connected to the output shaft 84B.

[0034] Also, the adjustment gear 9B of this embodiment is disposed between the first clutch 51 and the spool 6. The adjustment gear 9B absorbs the difference between the rotational force (rotation speed) input from the handle 2 via the manual shaft gear 3B and the rotational force input from the motor 7 via the electric shaft gear 8B, and matches them. The adjustment gear 9B of this embodiment is a planetary gear mechanism. However, the adjustment gear 9B may be a mechanical transmission mechanism other than the planetary gear mechanism.

[0035] [Operation of the 2-2 Reel Device] ·When manually winding In the reel device 1B, when manually winding the fishing line (line), the user makes the first clutch 51 in the engaged state and the second clutch 52 in the disengaged state by a predetermined lever operation or the like. In this state, when the user rotates the handle 2, the rotation is, for example, speeded up by the manual shaft gear 3B connected to the handle 2. Then, the spool 6 connected to the manual shaft gear 3B via the first clutch 51 rotates, and the fishing line is wound up at the speeded-up rotation.

[0036] ·When electrically winding When winding the fishing line by the motor 7, the user makes both the first clutch 51 and the second clutch 52 in the engaged state by a predetermined lever operation or the like. In this state, when the motor 7 is driven, the inner pole member 82B of the electric shaft gear 8B connected to the motor shaft 71 also rotates in the same direction. When the inner pole member 82B rotates, the spatial magnetic flux waveform of its inner pole magnet is modulated by the pole piece member 83B to have the same magnetic flux density waveform as the outer pole member 81B. Thereby, the decelerated torque is transmitted to the pole piece member 83B. Then, the spool 6 connected to the pole piece member 83B via the coupling mechanism 75 and the second clutch 52B also rotates in the same manner, and the fishing line is wound up at the shifted rotation. At this time, the difference between the rotational force (rotational speed) input from the motor 7 to the spool shaft 61 through the coupling mechanism 75 and the rotational force of the inner pole member 32 of the manual shaft gear 3 is absorbed by the adjustment gear 9.

[0037] [2-3 Technical Effects of the Present Embodiment] As described above, according to the second embodiment, the electric shaft gear 8B transmits the rotational force by the motor 7 to the spool 6 after shifting it by magnetic modulation. As a result, power (torque) can be transmitted from the motor 7 to the spool 6 without contact, so that power loss at the contact portion generated in the mechanical (contact type) torque transmission mechanism, mechanical noise (gear meshing noise), and changes in characteristics due to the contact state can be suppressed. In addition, the amount of maintenance that has been required in the past to suppress these can be significantly reduced. Therefore, an electric reel with good quietness and maintainability can be provided.

[0038] <3. Third Embodiment> FIG. 5 is a cross-sectional view schematically showing the reel device 1C according to the third embodiment. As shown in FIGS. 4 and 5, in the reel device 1C according to the third embodiment, both the manual shaft gear and the electric shaft gear are magnetic modulation gears. Specifically, the reel device 1C includes a manual shaft gear 3 similar to that of the first embodiment and an electric shaft gear 8B similar to that of the second embodiment. Even during operation, the manual shaft gear 3 functions in the same manner as in the above-described embodiment during manual winding, and the electric shaft gear 8B functions in the same manner as in the above-described embodiment during electric winding.

[0039] Even with such a reel device 1C, the same effects as those of the first embodiment and the second embodiment can be obtained. That is, by using the manual shaft gear 3 and the electric shaft gear 8B as magnetic modulation gears, their quietness and maintainability can be improved. In addition, changes in the drag force can be suppressed compared to a friction type drag.

[0040] <4. Fourth Embodiment> [4-1 Configuration of Reel Device] FIG. 6 is a cross-sectional view schematically showing the reel device 1D according to the fourth embodiment. FIG. 7 is a cross-sectional view schematically showing the reel device 1D according to a modification of the fourth embodiment. As shown in FIGS. 4 and 6, in the reel device 1D according to the fourth embodiment, the manual shaft gear and the electric shaft gear are differentially connected so that the manual winding can be assisted (supported) by the motor 7. Specifically, the reel device 1D includes a manual shaft gear 3D instead of the manual shaft gear 3 in the first embodiment, and also includes an electric shaft gear 8B similar to that in the second embodiment.

[0041] The manual shaft gear 3D is a magnetic modulation gear similar to the manual shaft gear 3 in the first embodiment (see FIG. 2), but the pole piece member 33D is not fixed to the frame 10 and is connected to the electric shaft gear 8B. More specifically, the pole piece member 33D is connected to the output shaft 84B of the electric shaft gear 8B via a coupling mechanism 75. Further, the pole piece member 33D is connected to a one-way clutch 35D. The one-way clutch 35D rotates the pole piece member 33D only in one direction that increases (more speeds up) the gear ratio of the manual shaft gear 3D. The inner pole member 32 is the same as in the first embodiment, and the shaft 32a is connected to the spool 6 via the first clutch 51. In FIG. 6, for the sake of illustration, the shaft 32a intersects the coupling mechanism 75, but they do not actually interfere with each other.

[0042] The reel device 1D also includes a detection unit (not shown) that detects the input torque input from the handle 2, and a control unit 73D such as a microcomputer. The detection unit may be a torque sensor, a speed sensor, or a position sensor. The control unit 73D controls the operation of the motor 7 based on the input torque detected by the detection unit, and performs operations such as ON / OFF switching and output adjustment of the motor 7. Thereby, the operation of the motor 7 is preferably controlled regardless of the user's operation. In the reel device 1D, as described above, the manual shaft gear 3D and the electric shaft gear 8B are differentially connected so that the difference in rotational force between them can be absorbed. Therefore, an adjustment gear that performs the same function is not required.

[0043] [4-2 Operation of the Reel Device] ·During manual winding In the reel device 1D, when manually winding the fishing line (line), in the same manner as in the first embodiment, the rotational force applied by the user to the handle 2 is speeded up, for example, by the manual shaft gear 3D. Then, the spool 6 connected to the manual shaft gear 3D via the first clutch 51 rotates, and the fishing line is wound up at the speeded-up rotation. At this time, the pole piece member 33D of the manual shaft gear 3D is restrained by the one-way clutch 35D and does not rotate. In this case, a second clutch that disengages the edges of the manual shaft gear 3D and the electric shaft gear 8B may be provided between them.

[0044] ·During electric assist During manual winding, the manual torque input from the handle 2 is detected by the detection unit. When the detected torque value exceeds, for example, a preset threshold value, the control unit 73D drives the motor 7. Then, in the same manner as in the second embodiment, the output of the motor 7 is decelerated via the electric shaft gear 8B. This rotational force is transmitted to the pole piece shaft 33D via the coupling mechanism 75, and the pole piece shaft 33D is rotated in the opposite direction to the manual shaft 31D. As a result, the relative rotation between the pole piece member 33D and the outer pole member 31D is increased, and the axial torque of the handle 2 connected to the outer pole member 31D is reduced.

[0045] ·During electric winding When winding the fishing line only by the motor 7, the user connects the first clutch 51 to the connected state by a predetermined lever operation or the like. In this state, when the motor 7 is driven without operating the handle 2, in the same manner as in the second embodiment, the output of the motor 7 is decelerated via the electric shaft gear 8B. This rotational force rotates the pole piece member 33D of the manual shaft gear 3D via the coupling mechanism 75. When the pole piece member 33D rotates, the spatial magnetic flux waveform of the pole piece 33a is modulated by the outer pole member 31D, and the rotational torque is speeded up and transmitted to the inner pole member 32D. Then, the spool 6 connected to the inner pole member 32D via the first clutch 51 also rotates in the same direction as the inner pole member 32D, and the fishing line is wound up at the shifted rotation.

[0046] [4-3 Technical effects of this embodiment] As described above, according to the fourth embodiment, the manual shaft gear 3D is a differential gear, and the output shaft 84B of the electric shaft gear 8B is connected to the pole piece member 33D (differential shaft) of the manual shaft gear 3D. Thereby, the manual input from the handle 2 can be suitably assisted by the power of the motor 7. That is, in the conventional electric reel, the main purpose of using the motor was the electric winding only by its power. However, in the reel device 1D of the present embodiment, it is possible to use an electric assist mode in which the manual input from the handle 2 is assisted by the power of the motor 7. In addition, the manual shaft gear 3D and the electric shaft gear 8B are differentially connected to absorb the difference in the rotational forces of each other. Therefore, an adjustment gear that performs the same function can be made unnecessary.

[0047] Further, according to the fourth embodiment, the input torque input from the handle 2 is detected by the detection unit, and the operation of the motor 7 is controlled based on the detected input torque. Thereby, the user can suitably control the operation of the motor 7. That is, in the conventional electric reel, since the user adjusted the speed by manually operating the lever, it was difficult to finely adjust the speed, and problems such as an unexpected line break occurred. In this regard, in the present embodiment, the user can intuitively adjust the assist force by operating the handle without relying on the lever operation. Furthermore, since the operation of the motor 7 can be controlled regardless of the user's operation, the operation lever for driving the motor (see FIG. 9) provided in the conventional electric reel becomes unnecessary. Thereby, the reel device 1D can be configured to be simpler and more compact.

[0048] In the reel device 1D, as shown in FIG. 7, the manual shaft gear 3D, the motor 7, and the electric shaft gear 8B may be arranged coaxially. In this case, the motor 7 and the electric shaft gear 8B may be arranged inside the spool 6 (or on the side opposite to the input side with respect to the spool 6), and may be connected to the manual shaft gear 3D or fixed to the frame 10 without interfering with the spool 6. Thereby, the motor 7, the spool 6, the electric shaft gear 8B, the handle 2, and the manual shaft gear 3D are arranged in a state where their rotation center axes (Ax1, Ax2, Ax3) are located on the same straight line. Therefore, the reel device 1D can be configured compactly. Also in this case, the magnetic pole piece member 33D of the manual shaft gear 3D may be directly connected to the magnetic pole piece member 83B of the electric shaft gear 8B. Thereby, the connecting mechanism 75 can be made unnecessary.

[0049] <5. Fifth Embodiment> FIG. 8 is a cross-sectional view schematically showing a reel device 1E according to the fifth embodiment. As shown in FIGS. 4 and 8, the reel device 1E according to the fifth embodiment is different from the fourth embodiment in that the electric shaft gear 8E is a mechanical transmission mechanism instead of a magnetic modulation gear. The electric shaft gear 8E is, for example, a planetary gear mechanism, but is not particularly limited and may not be a differential gear.

[0050] Also with such a reel device 1E, similar to the fourth embodiment, the manual input from the handle 2 can be suitably assisted by the power of the motor 7.

[0051] <Others> The embodiments of the present invention have been described above, but the present invention is not limited to the above embodiments.
