ABSTRACT:
The invention disclosed relates to a fastening suitable for a personal ornament, which comprises a male member (A) and a female member (B); the male member (A) including a base plate 21 on which a projecting portion 22 is provided; the female member (B) including a casing 23 which has a base plate 25 and an upstanding edge 26 formed by bending a marginal portion of the base plate 25. The base plate 25 has an opening 24 which can receive the projecting portion 22, and the upstanding edge 26 has an opening 27 through which an ornament-fitting portion 30 of a ring plate 28 may be projected outwards. The ring plate 28 has an opening 29 whose diameter is larger than that of the opening 24 of the base plate 25. The ring plate 28 has the ornament-fitting portion 30 in the form of a projection. The ring plate 28 is placed in the casing 23 in such a manner that the ornament-fitting portion 30 projects through the opening 27. A ring-like cover plate 31 is placed on the upper surface of the ring plate 28. The cover plate 31 has an opening 32 whose diameter is virtually the same as that of the opening 24 of the base plate 25. A partially opened annular spring 34 is placed on a recess channel which is defined by the upper surface of the base plate 25 of the casing 23, by the internal wall of the ring plate 28, which wall surrounds the opening 29, and by the lower surface of the ring-like cover plate 31, whereby the spring 34 is disposed on the recess channel in such a position that an internal portion of the spring 34 is present in an internal area of the openings 24 and 32. The upstanding edge 26 of the casing 23 is bent inwards to fix the ring-like cover plate 31.
