Abstract: In a fishing reel, a spool (200) can be easily and firmly assembled with a housing (100) and is not unexpectedly separated from the housing after assembled, and the rotation of the spool in one direction can be braked without moving a main shaft (110) relative to the housing. The fishing reel has a housing and a spool. A main shaft is fixed to a hub (130) of the housing. The spool has a winding drum (210) disposed at a center thereof. The winding drum contains a one-way clutch integrally fixed thereto. A sleeve surrounds a central portion of the main shaft with being in contact with the central portion. The sleeve is fitted in the one-way clutch and permitted to rotate in only one direction by the one-way clutch when the spool has been assembled with the housing. The spool can rotate in only one direction relative to the housing when the frictional force between the main shaft and the sleeve is adjusted to be maximum. The spool can rotate in either direction more freely as the frictional force is decreased.
