Patent ID: 7232087

Claim:
A spinning reel spool assembly comprising: a spool having a drag housing recess formed in an internal circumferential surface of the spool, the drag housing recess having at least one interlock groove extending in a longitudinal direction of the spool, and a flange fastening member having a tubular section threaded into the drag housing recess; and a spinning reel drag mechanism configured to brake a rotation of the spool and arranged between the spool and a spool shaft, the spinning reel drag mechanism including at least one first drag washer having an outer circumferential portion with at least one interlock protrusion configured to engage with the interlock groove, the outer circumferential portion being free of an interlock protrusion at a section diametrically opposed to the at least one interlock protrusion, the at least one first drag washer being non-rotatable with respect to the spool in the drag housing recess and having an outside diameter that is smaller than an internal diameter of the tubular section of the flange fastening member. at least one second drag washer configured to be arranged with respect to the first drag washer along the longitudinal direction of the spool, the at least one second drag washer being non-rotatable with respect to the spool shaft, the at least one second drag washer having an outside diameter that is smaller than an internal diameter of the tubular section of the flange fastening member, and a drag knob configured and arranged to be threaded onto the spool shaft to selectively adjust an amount of pressure acting on the first and second drag washers, the internal diameter of the tubular section being smaller than a maximum dimension of the at least one first drag washer, the maximum dimension being a length from an outermost edge of the at least one interlock protrusion to the outer circumferential portion at the section diametrically opposed to the at least one interlock protrusion.
