ABSTRACT:
A pair of arms provided with brake shoes is mounted onto a cycle body via a mounting plate, so as to be freely rotatable, and an adjustment metal is installed between a shaft on the mounting plate and a bossed section of one arm, one edge of said adjustment metal being engaged onto the bossed section and the other edge being indirectly connected to the aforementioned shaft. The return spring tension can be strengthened or weakened by rotation of this adjustment metal from outside. The clamping protrusions on the adjustment metal are made to engage onto the ratchets on the stop ring by strong pressure from a spring element.
