BURIED MATERIAL COVER BODY

PROBLEM TO BE SOLVED: To facilitate recognition of the position of a peripheral direction center part and to facilitate aligning when connecting two buried material cover bodies. SOLUTION: A projecting part 13 projecting to a radial direction outside is formed at the peripheral direction center part, and the position of the peripheral direction center part can be recognized by visual observation. The projecting part 13 is formed into a shape in which an outside surface 13a becomes a projection to the radial direction outside as compared with a remaining part 14 and an inside surface 13a becomes a recess to the radial direction outside as compared with the remaining part 14. As a result, when two buried material cover bodies 10 are connected in a state of the one cover body 10 inserted into the other cover body 10, the projecting part 13 of the buried material cover body 10 arranged at the inside is fitted and aligned into the projecting part 13 of the other buried material cover body 10 to prevent displacement from the state.
