<p>PROBLEM TO BE SOLVED: To connect covers to each other surely with a simple structure by forming an engaging part provided with a bending member and a straight pipe member which are formed in a pipe shape by assembly of a pair of half bodies, and for connecting the bending member to the end part of the straight pipe member at a plurality of rotational angles, on each one end of the bending member and the straight pipe member. SOLUTION: A joint 10 consists of a bending member 11 and a straight pipe member 21, and used for connecting straight pipe shaped piping covers to each other on a bending wall surface and the like. In the bending member 11, an opening formed in the vicinity of the bending part 11a forms a connecting part 12, the other opening forms a connecting part 13. In the straight member 21, one opening forms a connecting part 22, and the other opening forms a connecting part 23. In both members 11, 21, the connecting part 22 is connected to the connecting part 12 at a prescribed rotational angle so as to form a series of pipe shaped bodies. A projection as an engaging part 14 is formed on the outer peripheral surface of the end part of the connecting part 12 is formed for connection, and recessed engaging part is arranged in a position corresponding to the engaging part 14 on the inner circumferential surface of each four end part of the connecting part 22.</p> |
