However, in the method of enlarging the knob of the fastener in a plane, the size of the fastener and the weight associated with the enlargement of the knob cause the knob to be washed during washing. It is not preferable because the inside of the tank of the machine is scratched. On the other hand, in the method of attaching a key holder or the like to the hole provided at the tip of the knob portion of the fastener, the decoration portion such as the key ring is pulled and operated, and in this case, the decoration portion such as the key ring itself is pulled by itself. Because it is not a structure to be used, if the decorative part is pulled, it will be easily cut from the connecting part between the decorative part and its chain, or from the connecting part between the annular bracket part attached to the fastener and the chain. It is not suitable as a fastener operation aid. Further, since the chain connecting the annular metal part to be attached to the fastener and the decorative part is long, it moves about more than necessary and is very troublesome. The present invention is intended to address such a problem, and the object has been achieved by completing the invention described below.
