<p>PURPOSE:To provide a marking body, for the detection of an underground buried object, wherein it is provided with a sufficient water-stopping property and a sufficient pressure-resistant property, it can be constituted easily and its detection ability is excellent. CONSTITUTION:In a marking body 1, a motion-responding means 2 which is buried near an underground buried object and which indicates the buried point of the underground buried object by responding to a detection signal sent out from the upper part of the ground is housed in the space part 30 of a container 3 constituted so as to fit circumferential faces 36, 37 at an upper lid 31 and a lower lid 32. A support part 33 is formed so as to be recessed toward the inside of the space part 30 from the outside of lid faces 34, 35 of the upper lid 31 and the lower lid 32 or one of them. The inside of the space part 30 is supported in the up-and-down direction by the support part 33, and a coil 21 as a constituent element for the motion-responding means 2 is installed between the circumferential faces 36, 37 at the upper lid 31 and the lower lid 32.</p> |
