According to the present disclosure, the base piece with an ornamental piece mounted thereon is coupled to the receiving member which is a part of any one of the various accessories or buttons by use of a magnetic coupling and through engagement of the projection in a special step-shaped engaging groove. Therefore, attachment and detachment of the ornament are easy and particularly, because the coupling requires a device which cannot be released by natural external forces while the device is in use, the ornamental piece is reliably prevented from dropping off of the base piece while in use and replacement of the ornamental piece by any of various accessories or ornamental buttons is easily and conveniently facilitated. |
