PURPOSE:To enable a key holder to be properly accommodated to the number or dimension of retained keys, and make the holder not bulky in carrying it, by enabling both the ends of the fastener element line of both surface duty teeth fitted on a flexible core, to be connected to or separated from each other, and by fitting both the surface duty teeth on each other or separating the teeth from each other with a slider having a pull. CONSTITUTION:At the time of using a key holder 10, a slider 13 is permitted to slide in the direction of opening and separating a fastener element line to the position of a separating device 14, and a butterfly rod 20 is pulled out of the internal section of a box body 19 via the slider 13. Then, the fastener element line 11 is set in the state of a piece of chain, and on the fastener element line 11, from the butterfly rod 20 end of one side end, a key K is passed via a key slot 21, a double link 22 or the like, and after that, the fastener element line 11 is bent in the shape of a loop, and the butterfly rod 20 is inserted into the box body 19 via the slider 13. When, by permitting the slider 13 to slide with a pull 12, both surface duty teeth 15, 15 are fitted on each other, and the separating device 14 is connected to, and the key K is retained in the loop section of the key holder 10. |
