Abstract: The invention relates to a fly reel, comprising a reel body portion (1), a line holder (2) journalled to the body portion (1) and rotatable relative thereto, a rotating linkage (A), as well as a transmission system (B) between the rotating linkage (A) and the line holder (2) for transmitting the rotating motion of rotating linkage (A) into the rotating motion of line holder (2). The rotating linkage (A) is provided with elements (13, 15, 16) for disconnecting transmission whenever a fly-fishing person no longer contacts rotating linkage (A) to produce the rotating motion of line holder (2) and transmit power. Thus, the reel crank does not rotate even if line were running out of the reel.
