Abstract: A rotatable-spool fishing reel has an arrangement such as a brake or clicker for influencing the rotation of the spool. A unidirectional coupling is provided between the line spool and the brake or clicker arrangement, so that the arrangement influences the spool's rotation only in one direction. The coupling is provided by a disk having unidirectional resilient pawls projecting from both of its faces, such that the selected rotational sense for influencing the spool rotation can be reversed by inverting the disk. The disk can be made as a one-piece molding in plastics, with its periphery adapted for engagement by the brake or clicker arrangement. The back of the spool has an annular series of abutments to engage the opposing pawl of the coupling element. The reel backplate may also have an annular series of abutments, to engage the opposite pawl and prevent rotation of the coupling element when the spool rotation is not to be influenced.
