This is a wear-resistant and corrosion-resistant fishing reel, comprising a reel main body, a spool rotating within the reel main body, and a handle connected to the spool through a transmission component. The reel main body has a transmission chamber for installing the transmission component, and on the side of the transmission chamber near the spool, there is an anti-corrosion partition. Inside the transmission chamber, there are several metal connecting pieces, each with a non-metal corrosion-resistant sheath. This design incorporates both anti-corrosion partitions and non-metal corrosion-resistant sheaths to enhance the overall wear and corrosion resistance of the fishing reel. The anti-corrosion partition, located at the transition between the transmission chamber and the spool, fills the space gap effectively, acting as a barrier and reducing the likelihood of corrosion due to potential differences during use.
