<P>PROBLEM TO BE SOLVED: To prevent generation of crack or the like caused by elastic deformation of each side wall part of a ventilation cover on one end part side toward the width enlarging side to drop from a ceiling wall part of a corner cover in shrink-packaging. <P>SOLUTION: A ventilation hole is formed at the ceiling wall part 5D of the corner cover 5 fixed to a wall outer surface in such a way as to cover a bent part of flexible piping or the like. On the outer surface side of the ceiling wall part 5D of the corner cover 5, the ventilation cover 7 is detachably installed to form a ventilation passage 8 with the outer surface of the ceiling wall part 5D to be opened roughly in an L shape in two directions over an opening 5b on one end side and the ventilation hole. At a position of the corner cover 5 facing one end part side of the ventilation cover 7 installed in a regular attitude on it, a deformation regulating means A to prohibit elastic deformation of each side wall part 7A of the ventilation cover 7 in the width direction outward is provided. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
