<P>PROBLEM TO BE SOLVED: To eliminate the need of providing a mechanism for undercut treating, to enable reduction in production costs of a mold and to improve the holding force of a locking claw part by means of an expanded portion. <P>SOLUTION: The lid body 10 comprises a body 12 roughly the same size as an opening part 11, an extended part 14 connected to the body 12 via a thin thick part 13, a locking claw part 16 projected to the front surface 15 of the extended part 14, a window part opened in the extended part 14 at a position overlapped with the locking claw part 16 and an expanded part 23 projected from the rear surface 22 of the extended part 14 at a position overlapped with the window part. Under a form of a resin molding, the lid structure displays a flat state as a whole, while at a time of engagement, the extended part is bent to the main body part at the thin thick part. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
