<P>PROBLEM TO BE SOLVED: To efficiently ensure rigidity of a whole trunk lid, and also effectively distribute stress thereof. <P>SOLUTION: A skeleton structure for a trunk lid includes an inner panel having an upper surface part 10A and a rear surface part 10B, and fixed via hinges 6 connected to both ends in a vehicle cross direction on the front side of the upper surface part 10A. The inner panel has a main skeleton 11 extending along both edges in the vehicle cross direction of the upper surface part 10A and the rear surface part 10B between connection parts 40 to the hinges 6 and lower corners 10D of the rear surface part 10B, and a sub skeleton formed over the upper surface part 10A and the rear surface part 10B at the further inside in the vehicle cross direction than the main skeleton 11. The sub skeleton has upper surface oblique sides 12a on the upper surface part 10A, extending from near the connection parts 40 backward to the inside in the vehicle cross direction, and rear surface oblique sides 12b on the rear surface part 10B, extending from near the main skeleton 11 extending to the rear surface part 10B upward to the inside in the vehicle cross direction. The upper surface oblique sides 12a and the rear surface oblique sides 12b are connected to each other on a boundary between the upper surface part 10A and the rear surface part 10b. <P>COPYRIGHT: (C)2013,JPO&INPIT |
