ABSTRACT:
A rotation support structure for a dual-bearing reel includes a reel unit, a spool shaft, and fluid bearings. The spool shaft is disposed on an inner circumferential side of the reel unit and can rotate relative to the reel unit. The fluid bearings have a plurality of grooves for forming a fluid lubricant film between the reel unit and the spool shaft. The rotation support structure is provided for a high-speed rotation operation of a dual-bearing reel, with which a reduction of the rotation performance during high-speed rotation can be successfully suppressed.
