<p><P>PROBLEM TO BE SOLVED: To allow a carriage to smoothly move on an RFID (Radio Frequency Identification) tag for road surface construction while maintaining communication property of an RFID communication part. <P>SOLUTION: The tag includes: an RFID communication part 2 which communicates with an RFID reader 110; and a holding part 3 which holds the RFID communication part 2. The RFID communication part 2 is communicable when a distance to a road surface is equal to or larger than a predetermined value. The holding part 3 which is elastically deformable, becomes thinner when a stepping load is generated and is restored in a non-load state. When the tag 1 has no load, the RFID communication part 2 is located in a communicable region U and communicates with the RFID reader 110. When the stepping load is generated by a wheel R, the thickness of the tag 1 is reduced by elastic deformation of the holding part 3, and the RFID communication part 2 is located in a non-communicable region D. Thus, since the tag secures communication property of the RFID communication part and its thickness is reduced when the stepping load is generated, there is no influence on traveling of the carriage. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
