PROBLEM TO BE SOLVED: To improve efficiency of inspection works and effective utilization for traceability by finding a method in which an in-metal type RFID mounted on a clamp does not come off even if repeatedly used for a long time under severe conditions.SOLUTION: An in-metal-type RFID tag 40 is buried into at least either one of the pair of body plates 11 and 11 constituting a clamp body 16, in a state in which the surface of the same is slightly projecting within the thickness range of a reinforcing plate 31 from the outer surface of the body plate. By storing information such as types of the clamp concerned in the IC chip in a tag is stored, an inspection work can be easily performed. On the surface of the tag, a minus engraved mark 46 indicating a detection direction of the IC chip are provided, by arranging such that the detection direction is to be vertical direction in a vertical suspension clamp 10, when trying to bring a device close for reading and writing, the reinforcing plate stands clear resulted in possible smooth detection. |
