Abstract
A sliding-type faster for accessary chain has a hollow sphere having a pair of through holes, an elastic disk having a hole provided in the hollow sphere, and an accessary chain that slides into the through hole of the elastic disk. The outer diameter of the elastic disk for inserting the accessory chain is smaller than the inner diameter of the hollow sphere so that the outer surface of the elastic disk does not press tightly against the inner wall surface of the hollow sphere. Material such as polyurethane having high elasticity can be used for the elastic disk. The elastic disk can easily be installed in the hollow sphere by pressing or rolling it into a ball. Because of its increased thickness, the elastic disk will not slip out from the hollow sphere and achieve a long life.
