PROBLEM TO BE SOLVED: To provide piping covers capable of reducing the number of part items, and capable of alleviating burdens on a worker at the assembling of the piping cover.SOLUTION: Screw holes (6a, 6b, 6c and 6d) are formed at four corners of a ceiling plate (6A) of a piping cover (1A). The screw hole (6a, 6c) are in such a relationship that the screw holes in diagonal positions come in the same position when rotating the ceiling plate (6A) at angles of 180°, and arranged in positions different in distance from ends of the ceiling plates (6, 6A and 6B) with respect to the adjacent screw holes (6b, 6d). At the one-end side of the ceiling plate (6A), one screw hole (6b) out of the adjacent screw holes (6a, 6b) is arranged at an end position of a sidewall member (2B) of the piping cover(1A) within a range that the ceiling plates (6A, 6B) are overlapped with each other, and the other screw hole (6a) is arranged at an end position of a sidewall member (2C) of the other piping cover (1B) within a range that the ceiling plates (6A, 6B) are overlapped with each other. |
