Abstract

PROBLEM TO BE SOLVED: To prevent permanent set by fatigue through reinforcement of a curved region and conceal crackings, by affixing overlappingly in a single piece a flexible reinforce cover plate whose base end edge is fixed, to the top of the back plate. SOLUTION: The flexible reinforce cover plate 10 is overlapped so as to cover the whole surface of a curved region of a covering lid 8 covering an opening 6 in the oversurface of an accommodation part 1. The cover plate 10 has a surface consisting of an oxide colored and lustered to the same color as the skin 8b and affixed to its surface by a bonding agent or two-side adhesive tape. The base end edge of the cover plate is folded back in such a way as enwrapping the base end of the covering lid 8 and sewn on the back plate 2 solidly. Because the base end edge of the cover plate 10 is secured to the top of the back plate 2 and affixed overlapped to the whole surface of the curved region of the lid 8, the part with curved region to be folded repetitively is particularly reinforced, and generation of a permanent set in fatigue can be precluded. Even if the skin 8b of the lid 8 is of cordovan leather, crackings apt to occur in the part with curved region can be concealed.
