By the way, conventionally, in the spool of the double-bearing type reel of this kind, the fishing line winding body is formed thick in order to maintain a desired strength. If the spool is made thicker, the weight of the spool will be heavier and the entire reel will be heavier, and the moment of inertia will increase with the weight of the spool, leading to a decrease in fishline release characteristics. Has been done.

Further, in the case of an electric reel, if heat dissipation is not ensured, the heat of the spool drive motor that has generated heat is transmitted to the spool, making it difficult to perform the summing operation of the spool when releasing the fishing line.
Further, the heat generation may deteriorate the performance of the spool drive motor. Therefore, in the electric reel, reduction in weight of the spool and improvement of heat dissipation have been raised as problems to be solved.

The present invention has been devised in view of the above circumstances, and aims to reduce the weight of the spool while maintaining its strength.
