Abstract
An oil reservoir for an oil burner capable of ensuring oil-tightness between the oil reservoir and a partition with simple operation and structure and reducing a manufacturing cost. In the oil reservoir, a partition plate and a cover plate are provided with a plurality of spot welding portions and opposite to each other through an annular overlap formed therebetween. One of the partition plate and cover plate is formed at the overlap with an annular projection which is arranged in a manner to project toward the other to forcedly press the partition plate and cover plate against each other and the overlap is arranged at or near the spot welding portions, whereby the partition plate and cover plate are oil-tightly connected together.
