invention won a fishing reel spool backlash (backlash) to prevent the centrifugal relates to a fishing reel having a braking system, More particularly, yet to be introduced into the swinging displacement of the brake shoe such that a plurality of parts by weight of a light-weight structure brought concentrated around the chukpin obtain a braking force by the centrifugal force by the friction with the brake pads of the brake disk, the brake disk Precision can be adjusted by moving the braking force, and in particular by rotating the dial on the controller is equipped with an external enhancement can be moved forward and backward brake disc braking power adjustable precision dramatically, Furthermore, the introduction of the protruding stopper to limit the angular displacement of the swing brake shoe and brake shoe and the brake is formed by making the first contact with the upward position than chukpin the disk, to ensure reliable operation of the brake shoe to provide a precise braking system will be on precision centrifugal braking system equipped with a fishing reel. Fine fishing reel centrifugal braking system having a frame according to the present invention to achieve the above object Shaft mounted on the frame Chukseol to the shaft, and fishing line winding spool And are arranged on one side of the spool rotation that works with the support member, a plurality of break-in spool so that the support member is coupled radial displacement due to the centrifugal force of rotation of the swing center to get a concentrated structure and light weight parts chukpin in through the chukpin Schwartz, and brake disc coupled to the frame, the brake disc and the brake shoe to adjust the distance controller that precisely controls the braking force of the The centrifugal braking system including Comprising the jidoe, the centrifugal braking system coupled to the support member, characterized in that comprises a brake shoe of the connection member with a protruding stopper to
