ABSTRACT:
A bicycle brake cable tension adjustment device permits the adjustment of the brake cable only in one direction and limits the movement of the same in the other. The present disclosure includes a suspension member having a vertical wall and a horizontal wall on each of which is provided a through hole, and an adjustment assembly mounted on the horizontal wall of the suspension member and a cable fixing assembly mounted on the vertical wall of the same. The adjustment assembly includes a bolt-like member having a through hole in the axial direction which is provided with a tapered inner wall with the diameter thereof gradually increased from the top to the bottom, and a spring biased guiding tube having a conic bottom end with two or three symmetrically-located steel balls disposed in through holes defined on the periphery of the conic bottom end which is in corresponding abutment with the tapered surface of the bolt-like member. A brake actuating cable is guided through the bolt-like member and the the guiding tube and is in contact with the steel balls, therefore, once the guiding tube is moved upward against the inner tapered surface of the bolt-like member, the steel balls will be pushed radially inward to clamp on the brake actuating cable, restraining the same to move; and by pushing downward the spring biased guiding tube, the conic bottom end will disengage with the tapered surface so to release the cable from the clamping of the steel balls, permitting the same to be pulled in either direction for adjustment.
