Resin structure

A The resin structure comprising:

• a box-shape main body having a plurality of regions dividing inside of the main body;
• and
• a plurality of lids assembled to the main body to cover corresponding each of the plurality of the regions,
• the main body having a first partition wall extending to separate between a pair of the regions among the plurality of the regions, the pair of the regions being adjacent each other,
• a first one of the plurality of the lids covering one of the pair of the regions and having a second partition wall provided at its edge portion to extend along the first partition wall,
• a second one of the plurality of the lids covering the other of the pair of the regions and having a third partition wall provided at its edge portion to extend along the first partition wall,
• the first partition wall and the second partition wall being located to overlap each other in a thickness direction of the first partition wall to form a multi-layer wall structure, and the first partition wall and the third partition wall being located to overlap each other in the thickness direction to form a multi-layer wall structure, upon the plurality of the lids being assembled to the main body, wherein
• the first partition wall has a second regulating portion engaging with both of the second partition wall and the third partition wall to regulate movements of the second partition wall and the third partition wall in a direction where the second partition wall and the third partition wall are separated from the main body, and
• the second regulating portion is engaged with the second partition wall and the third partition wall in a state where the second partition wall and the third partition wall are overlapped in the thickness direction.
