<P>PROBLEM TO BE SOLVED: To simply, easily and efficiently perform installation, removal and re-installation work to a wall surface, to prevent a screw from separating from the wall surface when external force acts with the screw slightly loosened, and to increase strength of a fixation part for inserting the screw. <P>SOLUTION: Opposite ends of a main body 11, which is formed to be elastically deformable in bending in a direction orthogonal to a laying direction of a protection duct and supports the protection duct, are formed with head passage spaces 16 through which a head of the screw can pass inward and outward, and the fixation part 21 fixed to the wall surface through the screw is formed with a shank movement space 27 which communicates with a screw insertion hole 23 and the head passage space 16 and in which a shank of the screw is relatively movable in parallel in a direction orthogonal to the laying direction of the protection duct in the state that the screw is loosely screwed in the wall surface. <P>COPYRIGHT: (C)2009,JPO&INPIT |
