ABSTRACT:
A bicycle having post couplings, e.g., a coupling of a handle post to a binding cylinder of a handle clamp, and a coupling of a seat post to a binding cylinder of a frame. The binding cylinder has an extension formed on a side of it. Two slanting holes perforate the extension in slanting directions toward the inner cylindrical opening of the binding cylinder. Two skew blocks are inserted into the respective slanting holes so that the ends touch the post member. The bolt penetrates bolt bores formed in the skew blocks. A nut is fitted to an end of the bolt and tightened. As the nut is tightened, the skew blocks move in the slanting direction of the holes to secure the post member. Since the direction of separation of the skew blocks deviates from that of the axis of the bolt, the friction between the blocks and the slanting holes resists vibrational forces tending to loosen the coupling.
