<P>PROBLEM TO BE SOLVED: To provide a clasp for an accessory, which is excellent in operability, and can be used as a spring ring and can be operated by one touch at a place such as a back of a neck. <P>SOLUTION: The clasp for an accessory includes a pair of connection members connected with connection axis at an intermediate place. A recess for engagement is provided at an open end of one connection member. At an open end of the other cylindrical connection member, a hook member capable of swinging is attached. The hook member is axially attached rotatably to the open end of the other connection member, and is forced to the direction of closing the hook by a spring stored in the cylindrical connection member at an opposite side to the position of the axial attachment of the engagement hook. The spring forces a small ball disposed at the other end in a manner that the small ball becomes stuck in a recess for the small ball at the axial attachment part of one of the connection member, in order to ensure the close state of the pair of the connection members while ensuring the opening state when the pair of connection members are opened. <P>COPYRIGHT: (C)2013,JPO&INPIT |
