A ROTOR BRAKING MECHANISM (54) BRAKES A ROTOR (3) WHEN A BAIL ARM (17) PIVOTS INTO THE LINE-RELEASING POSITION, AND INCLUDES A MOVING MEMBER (51) AND A BRAKING MEMBER (65) MOUNTED ON A MOUNTING GROOVE (2F) FORMED ON THE BASE END OF A CYLINDRICAL PORTION. THE BRAKING MEMBER (65) INCLUDES FIRST AND SECOND BRAKING MEMBERS (65A,65B), BOTH OF WHICH ARE MADE FROM AN ELASTIC MATERIAL AND ARE APPROXIMATELY SEMI-CIRCULAR IN SHAPE. THE FIRST BRAKING MEMBER (65A) AND THE SECOND BRAKING MEMBER (65B) ARE PRESS FITTED ONTO THE CIRCULAR MOUNTING GROOVE (2F) BY A SPRING MEMBER (66) MOUNTED ON A GROOVE FORMED IN THE OUTER PERIPHERY OF THE FIRST AND SECOND BRAKING MEMBERS (65A,65B). THE BRAKING MEMBER (65) INCLUDES A DRAG PORTION (65C) THAT FRICTIONALLY AND ROTATABLY ENGAGES WITH THE MOUNTING GROOVE (2F) AND A PLURALITY OF ENGAGING PORTIONS (65D) THAT ENGAGE WITH THE REAR END PORTION (51C) OF THE MOVING MEMBER (51). WITH THIS CONFIGURATION, THE BRAKING FORCE OF A ROTOR BRAKING DEVICE (54) IS STABILIZED.
