<P>PROBLEM TO BE SOLVED: To allow the entirety of a frame body to easily pass through a wall hole. <P>SOLUTION: A right frame part 14 and a left frame part 15 of a frame body 11 are provided with a deformation part 31 elastically deformable in order to displace a pair of boss parts 16 in a direction in which the boss parts are brought into contact with each other and separated from each other. By elastically deforming the deformation part 31, the frame body 11 can be inserted into a hollow part K while bringing the frame body into a state in which the rear surface side of the frame body 11 is swollen outward and warped so as to be arcuately curved. <P>COPYRIGHT: (C)2012,JPO&INPIT |
