Abstract
In a baitcast type fishing reel, there is provided a unitary cylindrical ceramic member secured about the crankshaft of the reel, the ceramic member having a sleeve portion extending through a one-way clutch. The ceramic member may include one or more substantially planar surfaces extending perpendicular to the longitudinal axis of the sleeve portion to affect operation of a drag mechanism.
Claims4
In a fishing reel having a frame, a line-carrying spool rotatably mounted relative to the frame, a crankshaft rotatably mounted relative to the frame, a driving gear rotatably mounted relative to the crankshaft and selectively responsive to rotation of the crankshaft to drive the spool, the crankshaft extending through a one-way clutch, and a drag mechanism for frictionally engaging the driving gear and causing the driving gear to slippingly follow rotation of the crankshaft, the improvement comprising:
- a unitary ceramic member secured about said crankshaft, said ceramic member further including:
- a first cylindrical sleeve portion extending through said one-way clutch;
- and
- a larger diameter second portion having a substantially planar surface extending perpendicular to the longitudinal axis of the first cylindrical sleeve portion;
- wherein said drag mechanism includes a drag washer and said planar surface of said ceramic member is in abutting relationship to said drag washer.

- a larger diameter second portion having a substantially planar surface extending perpendicular to the longitudinal axis of the first cylindrical sleeve portion;
- a third portion of a larger diameter than said second portion, said third portion having a substantially planar surface extending perpendicular to the longitudinal axis of the first cylindrical sleeve portion;
- wherein said drag mechanism does not include a separable drag washer and wherein said planar surface of said third portion directly abuts said driving gear.
