ABSTRACT:
The coaster brake of this invention is provided with a clutch cone screw-fitted to a driving body which is driven by pedals, to be axially movable in correspondence with the driving body's turning direction, a brake cone supported through a clutch mechanism which is not turnable in the forward direction, but which allows its turning in the reverse direction, and a brake members which is operated to apply brake on the hub shell by the aforementioned clutch cone moving to approach the aforementioned brake cone side, when the driving body is turned in a reverse direction. When the hub shell is turning in the forward direction, the brake action may be exhibited by applying to the driving body reverse rotation similarly top conventional coaster brake. Besides, the aforementioned brake cone is rotatable in the reverse direction by means of the clutch mechanism and as the driving body is subjected to a reverse turning, when the hub shell is not turning in the forward direction, the aforementioned brake cone will turn in the reverse direction integrally together with the driving body, the clutch cone and the brake member and in concert with the hub shell; thus, the coaster brake mechanism operates as a reverse driving mechanism.
