FIXING STRUCTURE OF PULLEY

摘要

PURPOSE: A pulley fixing structure is provided to tightly wind a wire around a first pulley and a second pulley by inserting a fixing pin into a fixing hole of the first and second pulleys. CONSTITUTION: A first pulley(20a) rotates around a rotation shaft(10). A first wire is wound around the first pulley. A second pulley(20b) is combined with the rotation shaft. The n first holes(22a) and m second holes(22b) are formed on opposite surfaces to the first and second pulleys. A fixing hole is formed by combining the first hole with the second hole. A fixing pin(24) is inserted into the fixing hole. The n is a natural number. The m is the natural number except the n.
