  • Patent number: 5411218
    Abstract: A drag mechanism for a fishing reel having a spool shaft supported at both the ends thereof. The drag mechanism employs rolling members as drag members so that the durability of the mechanism is enhanced, and the dragging function thereof is kept stable and good for a long time even under severe conditions under which sea water, sand or the like is likely to cling to the mechanism. One of drag member holders is secured to the spool of the reel so as to be rotated together with the spool. The other of the holders is secured to the spool shaft so as to be rotated together therewith. The tapered outside circumferential surface of one of the holders faces the tapered inside circumferential surface of the other of them. The rolling members are fitted in between the tapered surfaces. The drag mechanism can be used to drag the reverse rotation of the spool by frictional resistances to the rolling and sliding of the rolling members.
