A rotor braking mechanism brakes a rotor when a bail arm pivots into the line-releasing position, and includes a moving member and a braking member mounted on a mounting groove formed on the base end of a cylindrical portion. The braking member includes first and second braking members, both of which are made from an elastic material and are approximately semi-circular in shape. The first braking member and the second braking member are press fitted onto the circular mounting groove by a spring member mounted on a groove formed in the outer periphery of the first and second braking members. The braking member includes a drag portion that frictionally and rotatably engages with the mounting groove, and a plurality of engaging portions that engage with the rear end portion of the moving member. With this configuration, the braking force of a rotor braking device is stabilized.
