<P>PROBLEM TO BE SOLVED: To always surely connect between pearls and a chain regardless of a pearl diameter, to keep deterioration-free for a long period while damaging no pearls or impairing no attractive appearance. <P>SOLUTION: A through-hole 21 is formed along the diameter of pearls 2 constituting a chain pearl. From both ends of the hole, there are inserted columnar parts 82, 92 of a first and second support pins 8, 9 having heads 81, 91 in which a connecting ring 3 for connecting the chain is provided in a fixed condition. Then, the parts on the tip end sides of the columnar parts are engaged with each other, bonded with an adhesive 10 and connected. The outer diameter of the columnar part 82 of the first support pin 8 is slightly smaller than the inner diameter of the through-hole 21, with an engaging hole 82a formed in the tip end side. The outer diameter of a large diameter part 92a on the head part side of the columnar part 92 of the second support pin 9 is slightly smaller than the inner diameter of the through-hole 21, wherein the outer diameter of a small diameter part 92b on the tip end side is slightly smaller than the inner diameter of the engaging hole 82a. The inner peripheral face of the through-hole 21 of the pearls 2 is bonded with an adhesive with the outer peripheral face of the respective columnar parts 82, 92 of the first and second support pins 8, 9. <P>COPYRIGHT: (C)2013,JPO&INPIT |
