1. The housing is equipped with a hub in the center.

2. The spool is equipped with a winding drum and built into a one-way clutch inside the winding drum.

3. The sleeves are inserted into the internal side of the one-way bearing allowing one-way rotation by the one-way bearing.

4. The main axis is fixed in the hub of the housing and inserted in the inside of the housing.

5. The fishing reel uses one method for connecting the spool with the housing and another method for adjusting friction between the main axis and sleeves, making bi-directional rotation or unidirectional rotation of the spool on the housing.
