  • Patent number: 4480802
    Abstract: A silencer of an anti-reverse fishing reel comprises a rubbing block adhered onto a catch which prevents the reverse rotation of a ratchet of the fishing reel and a buffer recess with a wide opening formed on the catch. Whenever normally rotating the ratchet of a fishing reel, the driving gear of the fishing reel will frictionally carry the rubbing block and the catch to a position outside the rotating radius of the ratchet teeth so as to eliminate the clicking sound generally produced between the ratchet and catch. The buffer recess has a wide opening on the catch providing a buffer space for releasing the catch from the ratchet teeth.
