Abstract

This spool 10 is provided with a first spool unit 11, a second spool unit 12, and a support mechanism 13 for supporting the second spool unit 12. The first spool unit 11 is provided with a short cylindrical unit 14, and a fishing line is wound around the short cylindrical unit 14. The second spool unit 12 is provided with a short cylindrical unit 25, and another fishing line is wound around the short cylindrical unit 25. The first spool unit 11 is provided with a support shaft 18, and the second spool unit 12 is provided with a receiver shaft 29. The support mechanism 13 is constituted of the support shaft 18 and the receiver shaft 29. The receiver shaft 29 is coupled to the support shaft 18 so that the second spool unit 12 is housed inside the first spool unit 11. The second spool unit 12 rotates inside the first spool unit 11. The support shaft 18 is provided with a stopper 22 which prevents an unintentional removal of the second spool unit 12 from the first spool unit 11.

       9 . The spool according to  claim 8 , wherein 
 the support mechanism comprises:    a support shaft provided in one of the first spool unit and the second spool unit; and    a receiver shaft provided in the other one of the first spool unit and the second spool unit to be coupled to the support shaft.    
   
   
       10 . The spool according to  claim 9 , wherein 
 the spool further comprises a stopper for preventing the fitting between the support shaft and the receiver shaft from being released.    
   
   
       11 . The spool according to  claim 8 , wherein 
 the flange or the side member is provided with a line holder for holding an end of the fishing line.    
   
   
       12 . The spool according to  claim 8 , wherein the second spool unit comprises a knob to be gripped by an angler.  
   
   
       13 . The spool according to  claim 8 , wherein a rib is formed on the outer periphery of the fist short cylindrical unit or the second short cylindrical unit along a circumferential direction.
