Abstract:
The present invention is a quadrangular cell case 1 for a vehicle cell, wherein a bottom part 6, lateral walls 2, 3, 4, 5, and an opening part 7 are integrally formed from one sheet of an aluminum alloy plate into a case that has each of these parts and is rectangular in transverse cross-section; and, before a lid is seal-welded to the opening 7, upper portions 2c, 3c, 4c, 5c of the lateral walls 2, 3, 4, 5 to be welded are locally increased in thickness so as to protrude into the cell case. The quadrangular cell case 1 for a vehicle cell is made of aluminum alloy, and it is possible to form a bead configuration that has stabilized during seal-welding, and to form sound weld portions.
