Abstract
PURPOSE:To obtain readily a braking force not less than a leading effect, by operating an operation arm to cause a shoe supported by a holder having a cam surface to become in contact with an inner circumferential surface of a drum by the collaboration of the cam and a rotating body. CONSTITUTION:When braking is applied while a bicycle is traveling, an operation wire W is pulled by an operation lever, then an operation arm 8 is swung around a fulcrum shaft 10, and a cooperating piece 81 on the arm 8 causes the shoe 2 and the holder 3 to swing around the rotating body 7. As a result, the shoe 2 becomes in contact with the inner circumferential surface of the drum 1, which results in the braking force. At this time, the rotational torque of the drum 1 is exerted on the shoe 2, and when the shoe 2 and the holder 3 are rotated along the cam surfaces 31, 61. consequently, the shoe 2 is forced to the inner circumferential surface of the drum by the rotating body 7 and the cam surfaces 31, 67 to generate a very large braking force.
