Abstract
A braking device for a two-wheeler, such as bicycle which comprises a pair of left and right arms pivotally attached to a frame of the two-wheeler, each having on its distal end portion a brake shoe, and a spring for energizing the arms to move toward brake releasing direction. This braking device is characterized in that one of the arms is more strongly energized by the spring than the other arm is, and that a stopper is provided to restrict the extent of the movement of the strongly energized arm toward the brake releasing direction, so that, when arms are being set back to the unactuated original state, this strongly energized arm is stopped of its movement by the stopper before the other arm finally returns to its original state.
