US 6,511,007 B1 · Double-bearing type reel

Abstract

The double-bearing type reel has a spool for winding up a fishing line and a drag mechanism 5 slipping to rotate the spool when a predetermined tension acts on the line wound round the spool. The drag mechanism comprises an outer ring, an inner shaft, a plurality of rollers arranged between the outer ring and the inner shaft so as to roll, and a torque adjusting section for moving the outer ring and the inner shaft relatively in an axial direction. The rollers are arranged between tapered roll surfaces which are an inner circumferential surface of the outer ring and an outer circumferential surface of the inner shaft and have center axes inclined against center axes of the outer ring and the inner shaft. The torque adjusting section adjusts slip torque of the outer ring and the inner shaft by pressing the outer ring and the inner shaft so as to move relatively in the axial direction, thereby the outer ring are slipped relatively by a tension exceeding a predetermined value acting on the line wound round the spool to rotate the spool and wind off the line. A circulation passage of lubricating oil is provided between the outer ring and the inner shaft passing through between the rollers and a plurality of through holes formed in the inner shaft. The outer ring has a radiating fin.
