  • Patent number: 5609309
    Abstract: A fly reel drag direction changer having a ratchet member of the changer which has a ratchet gear part and a circular silent cam slot formed in the ratchet gear part. A silent cam is elastically received in the silent cam slot such that the cam is selectively rotated along with the ratchet member due to elasticity but simply slides in the silent cam slot when the elasticity is overcome. A stopper has a recess for receiving an arm of the silent cam such that the stopper is rotated between a ratchet engaging position and a ratchet releasing position in accordance with the rotating direction of the ratchet member. The stopper is mounted to a rotatable coupling wheel such that the stopper is rotated between the ratchet engaging position and the ratchet releasing position and the rotatable coupling wheel is selectively rotated along with the ratchet member in the ratchet engaging position of the stopper.
