Anti-reversional mechanism for trolling reel

An anti-reversional mechanism adapted to be installed in a trolling reel having a housing, a main shaft rotatably mounted in said housing and coupled with a crank, at least one main gear fixedly mounted on the main shaft, a wheel shaft rotatably mounted in said housing and substantially paralleled to said main shaft, a winding hub rotatably mounted on said wheel shaft for winding a fishing line thereon, at least a second gear fixedly mounted on said wheel shaft and meshed with said main gear, a pressing wheel coupled with said second gear to be turned with said second gear, and friction means disposed between said pressing wheel and said winding hub for providing friction force in between said pressing wheel and said winding hub such that the pressing wheel can drive said winding hub to turn with said pressing wheel, said anti-reversional mechanism comprising:

• a ratchet wheel provided at an end of said pressing wheel;
• a control ring having a split such that the control ring is elastically clamped on the periphery of the pressing wheel, and at least one driving rod;
• and
• at least one pawl member having an end pivoted to said housing, an other end detachably engaged with said ratchet wheel for enabling said pressing wheel to be rotated in one direction and can not be rotated in a reversional direction, and an elongated slot for receiving said driving rod of said control ring.
