As described above, the reduction mechanism of the electric winder often includes a planetary gear mechanism in order to achieve a required reduction ratio. In addition, in order to reduce the size of the reduction mechanism, further reducing the size of the electric winder itself reduces the width of the meshing (engagement) of the gears, particularly in the direction of the rotation axis of the motor.

In addition, the conventional electric reel as described above has two planetary gear mechanisms in order to achieve a required reduction ratio. The first pinion carrier of the first stage planetary gear mechanism and the second sun gear of the second stage planetary gear mechanism are connected. More specifically, the inner peripheral portion of the cylindrical first pinion holder is engaged with the outer periphery of the second sun gear, and the first pinion holder and the second sun gear are caulked and fixed to each other. Do not move in the direction of the axis to achieve miniaturization of the planetary gear mechanism.

The rotation load from the motor and the rotation load from the operating lever are applied to the reduction mechanism as described above, and the reduction mechanism will deviate in the direction of the rotation axis of the motor due to long-term use, and the engagement of the gears will disengage.

In particular, in the conventional electric reel as described above, The caulking of the first pinion holder and the second sun gear is separated. If this caulking fixing is disengaged, and if the first pinion holder is greatly separated from the second sun gear in the axial direction, the engagement between the two will disengage, the rotation cannot be transmitted, and it cannot function as a reduction mechanism.

The object of the present invention is to prevent the deviation of the axial direction of the speed reduction mechanism, and even if the engagement of the gears is disengaged, the function of the speed reduction mechanism is still provided. Specifically, even if the caulking of the pinion holder of the planetary gear mechanism of the first stage and the sun gear of the planetary gear mechanism of the second stage is disengaged, it still functions as a reduction mechanism.

In this electric reel, the rotation of the motor is transmitted to the reel through a reduction mechanism. Here, if the reduction mechanism is moved in the direction of the rotation axis for any reason, for example, the meshing of teeth in the reduction mechanism may be disengaged, and the function of the reduction mechanism may not be provided.

Here, the rotation of the motor is transmitted toward the first planetary gear mechanism, and further transmitted to the second planetary gear mechanism through the first pinion holder of the first planetary gear mechanism. In addition, the decelerated rotation from the ring gears of these planetary gear mechanisms is transmitted to the reel.

Here, for any reason, there may be a problem with a structure (for example, caulking fixing) for restricting movement in the axial direction between the first pinion holder and the second sun gear.

Here, the electric reel according to the present invention is provided with a movement restricting mechanism to restrict the movement toward the speed reduction mechanism, specifically, the motor side of the first pinion holder. Therefore, the meshing of the first pinion holder and the second sun gear is maintained, and the rotations of the first pinion holder and the second sun gear are synchronized.

The clutch mechanism 37 switches the reel 4 to the rolled-up state and the free state. When the clutch is turned off (OFF), the clutch mechanism 37 is in the free state and the fishing line can be discharged. When the clutch is turned on, it becomes rolled up. The state is such that the roll-up operation by the motor 5 or the operation lever 2 is enabled. The clutch mechanism 37 includes one end of a pinion 36 and one end of a cylindrical shaft 42ca of a second pinion holder 42c. These facing end portions can be engaged with each other. When the pinion 36 is moved away from the cylindrical shaft 42ca, the clutch is released (the clutch is turned off), and the movement is performed in the opposite direction. The clutch is connected (clutch engaged (ON)). The clutch mechanism 37 can be turned on / off by a clutch operation mechanism (not shown).

[action]

First, when the clutch mechanism 37 rotates the motor 5 while the clutch mechanism 37 is connected (clutch engaged (ON)), the first sun gear 41 s rotates together with the output shaft 28. Accordingly, the first planetary gear 41p meshed with the first sun gear 41s and the ring gear Rg is revolved together with the first pinion holder 41c. In addition, since the first pinion holder 41c and the second sun gear 42s are connected, the second sun gear 42s also rotates in the same direction. Here, since the second pinion holder 42c is connected to the handle shaft 34 by the clutch mechanism 37, and the handle shaft 34 is prohibited from being reversed by the ratchet, the second pinion holder 42c is in a state where the revolution is prohibited. Therefore, if the second sun gear 42s rotates, the second planetary gear 42p will rotate to decelerate and rotate the spool 4 in a direction opposite to the rotation direction of the motor 5.

When the clutch mechanism 37 is connected (clutch engaged (ON)) and the operation lever 2 is rotated, the rotation of the operation lever 2 The rotation is transmitted to the pinion 36 through the traction mechanism 35. At this time, since the reverse rotation of the output shaft 28 of the motor 5 is prohibited by the one-way clutch 32, the first sun gear 41s does not rotate. In this state, if the rotation is transmitted to the pinion 36 by the operation lever 2, the second pinion bracket 42 c will revolve, whereby the second planetary gear 42 p will rotate while rotating the reel 4 while revolving.

In the operation described above, the caulking of the first pinion holder 41c and the second sun gear 42s may be disengaged. As described above, the first pinion holder 41c and the second sun gear 42s are engaged with each other by the plurality of teeth 41t and 42t. Therefore, even if the caulking is fixed and disengaged, the two are moved away from each other in the axial direction, the rotation can be still convey. However, if the moving distance in the axial direction of both is increased, the meshing with each other will be disengaged, and rotation cannot be transmitted.

Here, in this reel, a pinion holder movement restricting member 43 for restricting the movement of the first pinion holder 41c to the motor 5 side is provided, so that the movement distance in the axial direction of the first pinion holder 41c is suppressed. Specifically, when the first pinion holder 41c moves toward the motor 5, the support pin 41m of the first pinion holder 41c comes into contact with the pinion holder movement restricting member 43 fixed to the side of the zoning bracket 45, so that Movement to the motor 5 side of the first pinion holder 41c is restricted. Therefore, it is possible to prevent the meshing of the first pinion holder 41c and the second sun gear 42s from being disengaged, and the function of the reduction mechanism 6 is not impaired.

When the first pinion holder 41c is in contact with the pinion holder movement restricting member 43, the pinion holder movement restricting mechanism Since the contact 43 and the support pin 41m are in contact with each other, the braking force does not act on the rotation of the first planetary gear 41p by these contact.

The side surface of the gear 41p is also in contact with the large-diameter portion 43 'of the first sun gear 41s', so that the movement to the motor 5 side of the first pinion holder 41c can be restricted.

(c) In the foregoing embodiment, the first pinion holder is restricted by abutting the pinion holder movement restricting member 43 with the support pin 41m. 41c is moved, but for example, a first engaging portion such as a protrusion is provided on the first pinion holder, and a second engaging portion facing the first engaging portion in the axial direction is provided inside the roll, and These engaging portions may restrict movement in the axial direction of the first pinion holder by abutting.
