It overlaps with the frames 16A and 16B provided on the peripheral portions of the portions 2g and 2h. That is, at the peripheral edge portions of the first and second lids 12 and 13, the inward flange portion 2r that is a part of the frames 16A and 16B and the peripheral edge portion of the honeycomb-shaped rib 18 overlap each other. . Therefore, since the load input to the first and second lids 12 and 13 is input to the frames 16A and 16B via the ribs 18, the load resistance and resistance of the first and second lids 12 and 13 are increased. Impact properties can be increased. In particular, since the vertical wall portion 16c of the frame 16A and the honeycomb-shaped rib 18 overlap each other at the peripheral portion of the first opening 2g, the load resistance and impact resistance can be further improved.

  In addition, as is apparent from FIGS. 10, 3, 4 and the like, in the present embodiment, the first lid 12 is formed in a rectangular shape, and the honeycomb-shaped ribs 18 are vertical wall portions 18a constituting a unit hexagon.
