PROBLEM TO BE SOLVED: To provide a junction structure for a metal plate, which can joint three metal plates simply and reliably at small joint portions and which is excellent in liquid-tightness.SOLUTION: In a metal plate joint structure having a third metal plate positioned and jointed between opposing first and second metal plates, the third metal plate is formed with a penetration part penetrating in the plate thickness direction. From one of the first metal plate and the second metal plate, a seating face part to abut against the other of the first metal plate and the second metal plate through the through part of the third metal plate is protruded, so that the first metal plate and the second metal plate are jointed on the seating face part.SELECTED DRAWING: Figure 10 |
