2. Description of the Related Art For example, piping for a refrigerant of an air conditioner arranged on the outer wall of a building such as a house is designed to keep the appearance of the building beautiful and to protect the piping from shock, wind and rain. The cover may cover the outside. Such a piping cover is composed of a bottom plate portion arranged on the side of the outer wall of the building, the floor surface, or the like, and a cover body that covers the bottom plate portion to form an accommodation space for piping or the like. Further, depending on the external shape of the building, the pipe may be partially bent and attached. In such a case, as shown in FIG.
As shown in FIG. 3, a straight tubular pipe cover 90, 90 for covering a straight line portion of the pipe is provided with a joint 95 bent at a predetermined angle.
Are linked by. Reference numeral 91 is a bottom plate portion, 92 is a cover body, and 93 is a leg body.

However, when the joint 95 is connected to the straight pipe cover 90, it must be done via the joint 94, and the number of parts is increased, which requires time and labor for construction. Further, depending on the shape of the building and the installation location of the piping, the bending angle of the piping may not match the bending angle of the joint. However, since the joint is formed at a predetermined bending angle such as 45 degrees or 90 degrees and the angle is fixed, if the bending angle of the pipe is different from the bending angle of the joint, the adjustment is difficult. It was

Incidentally, the joint 95 and the straight tubular pipe cover 9
A free joint that can be connected even if there is a slight deviation from the zero end may be used as the joint 94. However, in this case the free joint part,
Unreasonable deformation force is applied to the end portion of the joint 95 and the end portion of the straight pipe cover 90, so that strain and the like remain at the connection portion after assembly, and it is difficult to finish the appearance beautifully.
