  However, in the state where the keys are stored in the pocket i with the above structure, when some external force F is applied between the eggplant ring body b and the support c as shown by the arrow in the figure, the banding h is The trousers g were easily removed or the trousers g itself was easily broken. Furthermore, the key f may fall due to the chain e being pulled out of the pocket i and being broken, which is dangerous especially when such an accident occurs while working at a high place. It was.

  On the other hand, when the chain e is taken out and the key f is locked / unlocked, if the length of the chain e is short, the eggplant ring body b must be removed from the banding h each time. It was annoying.

  Therefore, the present invention solves the above-mentioned problems, and the purpose of the present invention is to easily come off when a predetermined peeling force is applied between the eggplant ring body and the support. An eggplant ring that is easy to handle and a key holder using the eggplant ring are provided.

  In order to achieve the above object, the eggplant ring 1 of the present invention includes a hook portion 6 provided with a lock portion 7 for opening and closing a loop at one side opening end as shown in the embodiment of FIGS. The support 4 connected to the mounting base of the hook 6, the eggplant ring body 2 provided with the protrusion 13 projecting from the lower surface of the support 4, and the protrusion 13 are fitted in contact with the bottom surface thereof. A fitting 3 such as a key having a fitting hole 11 opened at the top is provided, and the protrusion 13 and the fitting 3 are detachably coupled to each other by a magnet 12.

  The mounting base of the hook portion 6 and the support 4 may be pivotally connected or fixedly connected.

  The protrusion 13 is formed of a magnet or a magnetic body, and a magnet or a magnetic body that is magnetically coupled to the protrusion 13 is provided in the fitting hole 11 of the fixture 3.

  The protrusion 13 is circular, and is characterized in that it is detachably fitted to each other by a magnet in the opening of the fitting hole 11 that is circular of the fixture 3.

  The mounting tool 3 is formed in a substantially cylindrical shape, and a mounting hole 9 into which the mounting ring 10 is inserted and held is formed in an intermediate portion thereof so as to penetrate left and right.
