The inside of the motor case 55 includes a spool motor housing portion 107 in which the motor doorway 91 opens on the end surface 65 side of the spool 53 by the holding portion 105 and a planetary gear mechanism mounting portion (on the end surface 67 side of the spool 53). 109 (hereinafter referred to as “mounting portion”) is partitioned and the right motor shaft 111 of the spool motor 83 projects into the mounting portion 109, and three planetary gears are provided between the right motor shaft 111 and the spool 53. A speed reduction mechanism 119 including mechanisms 113, 115, and 117 is accommodated and mounted.

As shown in FIGS. 1 and 3, a rotation drive shaft 121 that transmits winding power from the manual winding drive mechanism 61 to the speed reduction mechanism 119 is provided between the right motor shaft 111 and the right motor shaft 111 and the side plate 51. The rotary drive shaft 121 is supported on the bracket 77 and the side plate 51 via three bearings 123, 125, and 127 via a coaxial shaft.
As described above, the speed reduction mechanism 119 includes the three planetary gear mechanisms 113, 115, and 117, and after the spool driving force is reduced by the first planetary gear mechanism 113 when the spool motor 83 is driven. Further, the first planetary gear mechanism 113 is decelerated by the second and third planetary gear mechanisms 115 and 117 and transmitted to the spool 53. As shown in FIG. 2, the first planetary gear mechanism 113 has a non-circular outer periphery (D-shaped cross section).

Thus, the metal bearing 143 is detachably mounted in a recess 149 formed in the bearing portion of the sun gear 145 with respect to the right motor shaft 111.
Each planetary gear 147 has a structure in which the planetary gear 147 is always meshed with an internal gear 151 fixed to the inner periphery of the end surface 67 side of the accommodating portion 69 of the spool 53.

  As described above, this embodiment replaces the conventional structure in which the planetary gears 19 and 25 of the planetary gear mechanisms 11 and 13 are always meshed with the internal gear 21 provided on the inner periphery of the spool 5 as shown in FIG. An internal gear 133 is provided on the inner periphery of the mounting portion 109 of the case 55, and the planetary gears 131, 139 of the first and second planetary gear mechanisms 113, 115 are meshed with the internal gear 133, so that the spool When the fishing line is fed out by switching 53 to the spool free state, the number of gears of the speed reduction mechanism 119 that rotates in conjunction with the spool 53 is reduced to reduce the rotational frictional resistance due to the meshing of the gears.

The plurality of planetary gears 131 are supported by the first carrier 153, and the carrier 153 is coupled to the sun gear 137 described above so as to be integrally rotatable.
The plurality of planetary gears 139 are supported by the second carrier 155, and the carrier 155 is coupled to the sun gear 145 described above so as to be integrally rotatable.
Further, the plurality of planetary gears 147 are supported by a third carrier 157, and the carrier 157 is connected to the rotation drive shaft 121 via a locking pin 159 as shown in FIG. 3.

  As shown in FIG. 1, on the rotational drive shaft 121, while giving a braking force to the spool 53 that rotates by feeding the fishing line, a braking action that allows the spool 53 to rotate in the fishing line feeding direction is given. A conventionally known drag device 161 for switching the spool 53 between the spool free state and the fishing line winding state by using this braking action is mounted, and the drag force of the drag device 161 is attached to the side plate 51 on the rotary drive shaft 121. A drag lever 163 for adjusting the angle is attached. A pinion 167 is fitted to the outer periphery of the pressing body 165 constituting the drag device 161 so as to be integrally rotatable with the pressing body 165, and the drive gear 169 of the manual winding drive mechanism 61 is engaged with the pinion 167.

  As is well known in the art, the manual take-up drive mechanism 61 includes a handle 63, a handle shaft 171 to which the handle 63 is attached, and a drive gear 169 that is fixed to the handle 63 as shown in FIGS. At the insertion tip side of the handle shaft 171, when the spool 53 is driven to wind by the spool motor 83, the reverse rotation prevention device 173 prevents the reverse rotation so that the handle shaft 171 does not rotate in conjunction with this. Is provided.

  The anti-reverse device 173 includes a ratchet 175 that is fixedly engaged with the handle shaft 171 and a locking claw (not shown) that always locks the ratchet 175 with a constant urging force. When the spool 53 is driven to wind, the latching claw engages with the ratchet 175 in the rotation direction, and the rotation of the ratchet 175, that is, the rotation of the handle shaft 171 is prevented.

Accordingly, the driving force of the spool motor 83 is transmitted only to the spool 53 via the speed reduction mechanism 119.
On the other hand, when the spool 53 is rotated in the direction of winding the fishing line by operating the handle 63, the locking claw is configured to allow the ratchet 175 to rotate in the rotation direction. The handle shaft 171 can be rotated in conjunction with the rotation operation, and as described above, the one-way clutch 89 prevents the rotation of the motor shaft of the spool motor 83 during the fishing line winding drive by the handle operation. .

In addition, in FIG. 1, reference numeral 177 denotes a power supply cord connected to the connector 181 of the electric reel 179. Although not shown, the reel body 41 is provided with a control box equipped with an ON / OFF switch of the spool motor 83, and the spool motor 83 is driven / stopped by the operation of the ON / OFF switch. Yes.
Since the electric reel 179 according to this embodiment is configured as described above, the spool motor 83 can be driven by connecting the electric reel 179 to an external power source via the power supply cord 177.

  When the drag lever 163 is operated in the operating direction, a predetermined drag force is generated on the spool 53 by the drag device 161. If the handle 63 is wound up or the spool motor 83 is driven in this state, the drive is performed. The force is transmitted to the spool 53 by the speed reduction mechanism 119 or the manual take-up drive mechanism 61, and the spool 53 rotates to take up the fishing line. When the spool motor 83 is electrically wound, the spool motor 83 is driven first. The first sun gear 131 rotates at a high speed clockwise with the motor shafts 85 and 111.

  As a result, the planetary gear 131 is driven to rotate counterclockwise and revolves clockwise, so that the second and third sun gears 137 and 145 move on the right motor shaft 111 rotating at high speed, respectively, on the carriers 153 and 155. The rotation of the pinion gear 167 connected to the handle shaft 171 via the drive gear 169 is prevented because the rotation of the handle shaft 171 is blocked by the reverse rotation prevention device 173 in these rotation directions. Is regulated.

As a result, the rotational drive shaft 121 and the carrier 157 do not rotate, and the sun gear 145 rotates clockwise through the metal bearing 143, so that the planetary gear 147 supported by the carrier 157 moves around the sun gear 145. Rotates counterclockwise at a certain position without revolving.
Thus, in this state, the counterclockwise rotational movement of the planetary gear 147 is decelerated and transmitted to the internal gear 151, and the spool 53 rotates in the fishing line winding direction to wind up the fishing line. And at the time of this winding operation, the handle | steering-wheel 63 does not rotate interlockingly by the effect | action of the reverse rotation prevention apparatus 173. FIG.

Thus, the winding driving force of the spool motor 83 is sequentially decelerated by the first, second, and third planetary gear mechanisms 113, 115, and 117 and transmitted to the spool 53.
On the other hand, when the drag lever 163 is operated in the non-operating direction, the braking action by the drag device 161 is released and the spool 53 is switched to the spool free state, so that the fishing line can be fed out. In the embodiment, an internal gear 133 is provided on the inner periphery of the mounting portion 109 of the motor case 55, and the planetary gears 131 and 139 of the first and second planetary gear mechanisms 113 and 115 are meshed with the internal gear 133. In addition, because of the structure in which only the planetary gear 147 of the third planetary gear mechanism 117 is meshed with the internal gear 151 on the spool 53 side, the speed reduction mechanism meshes with the spool 53 when the fishing line is fed and rotates integrally therewith. The number of gears of 119 will decrease.

Therefore, according to the present embodiment, as compared with the electric reel of FIG. 4 and Patent Document 2, the rotational friction resistance due to the meshing of the gear is reduced when the fishing line is fed and the free performance of the spool 53 is improved. It became possible to pay out.
In the above embodiment, the motor case 55 is extended to the vicinity of the end surface 67 of the spool 53, and the mounting portion 109 is provided integrally. However, such a mounting portion is formed separately from the motor case. The motor case may be integrally mounted on the same axis.

  Of course, the present invention can also be applied to an electric reel provided with a clutch mechanism as shown in FIG.

It is principal part sectional drawing of the electric reel which concerns on one Embodiment of Claim 1 and Claim 2. It is the A section expanded sectional view of FIG. It is an expanded sectional view in the right side board of the electric reel shown in FIG. It is sectional drawing of the conventional electric reel.
