<P>PROBLEM TO BE SOLVED: To improve an appearance, by finely forming the whole protective cover, by arranging respective outer peripheral surfaces of two straight protective covers for storing and protecting a wiring-piping material arranged in a step height shape by straddling a step height part of a building wall and a protective cover connector for connecting the respective straight protective covers, on one surface of continuing in a substantially straight line shape. <P>SOLUTION: In a state of respectively storing opposed end parts C<SB POS="POST">1</SB>a of the two straight protective covers C<SB POS="POST">1</SB>, the two straight protective covers C<SB POS="POST">1</SB>are connected via the protective cover connector J<SB POS="POST">1</SB>, and in a state of connecting the two straight protective covers C<SB POS="POST">1</SB>via the protective cover connector J<SB POS="POST">1</SB>, a residual outer peripheral surface except for a surface opposed to the building wall W in the protective cover connector J<SB POS="POST">1</SB>, is constituted by extending in a straight line shape along the longitudinal direction so that the whole can be recognized as a series of straight line shapes. <P>COPYRIGHT: (C)2012,JPO&INPIT |
