RING SHAPE METALLIC FIXTURES

PROBLEM TO BE SOLVED: To provide ring shape metallic fixtures which are excellent in strength and used for a key holder, etc., to be easily produced. SOLUTION: The metallic fixtures are constituted by providing a nearly U shape main body part where a screw is formed at one end, a main body part opening/closing member which is formed by a wire and whose one end is supported via a hinge in the end part of the main body part at the opposite side of the screw so as to be freely rotatable and whose other end is freely contact/uncontact possible in the end part at the screw side of the main body part and a fixing member which is fitted with play to the other end of the opening/closing member so as to be freely rotatable and is provided with a screw hole to be fitted to the screw to fix the opening/closing member in a closing state by the screwing of the screw onto the screw hole when the end part of the main body part provided with the screw is in an adjacent state to the other end of a closing member. The fixing member is provided with a recessed groove being concentric with the screw hole on an outer peripheral surface, the wire constituting the opening/closing member is wound around the fixing member in a ring shape so as to permit at least a part of the wire to face into the recessed groove and, then, the fixing member is fitted with play to the opening/closing member so as to be freely rotatable and a rotation axis is made to be locking possible.
