  In order to catch a large fish, it is necessary to use an electric reel having a high driving torque for driving the spool. In order to increase the driving torque, it is necessary to increase the size of the motor. However, if the motor is increased in size, there is a problem that the electric reel becomes larger.

For this reason, the drive torque for rotationally driving the spool can be increased. That is, the driving torque of the spool can be increased without increasing the size of the electric reel. If the driving torque is the same as that of a conventional electric reel, the size of the motor can be reduced, and the electric reel can be downsized.

  Preferably, the stator is disposed concentrically with the rotating shaft of the spool. The rotor is at least partially housed in the spool.

  Preferably, the reel body has a first reel body portion and a second reel body portion. The first reel body is disposed on the first end side of the spool. The second reel body is disposed on the second end side of the spool. At least a part of the rotor is accommodated in the first reel body or the second reel body.

  Preferably, the motor is a flat motor.

  Preferably, the electric reel further includes an output shaft member extending along the rotation axis of the spool. The rotor can rotate integrally with the output shaft member.

  Preferably, the electric reel further includes a planetary gear mechanism that reduces the rotation of the output shaft member and transmits the rotation to the spool.

  Preferably, the spool and the rotor rotate integrally.

  Preferably, the motor is a brushless motor.

  The electric reel according to the present invention can increase the driving torque of the spool without increasing the size.

[Modification]
As mentioned above, although embodiment of this invention was described, this invention is not limited to these, A various change is possible unless it deviates from the meaning of this invention.

Modification 1

  For example, as shown in FIG. 3, the rotor 32 is accommodated in the second reel body 12. Specifically, the entire motor 3 is accommodated in the second reel body 12. According to this configuration, the diameter of the spool 2 can be reduced. Moreover, since the diameter of the rotor 32 can be made larger than the diameter of the spool 2, higher torque can be achieved.

  The motor 3 is a flat motor. That is, the motor 3 has a smaller axial dimension than a radial dimension. With this configuration, the space in the second reel body 12 can be used effectively.

Modification 2
In the above embodiment, the rotation of the rotor 32 is transmitted to the spool 2 via the planetary gear mechanism 8, but is not particularly limited thereto. For example, the spool 2 and the rotor 32 may rotate integrally. Specifically, as shown in FIG. 4, the rotor 32 may be fixed to the inner peripheral surface of the spool 2. In addition, a permanent magnet 322 may be attached to the inner peripheral surface of the spool 2, and the spool 2 may function as the rotor 32.
