Abstract
A packing having an annular shape in a longitudinal direction and a uniform cross section, includes a top surface arcuate part, a bottom surface side arcuate part, and side arcuate parts on both sides as viewed in cross section. Opposite ends of the top surface arcuate part and the side arcuate parts on both sides are connected by upper connection surfaces, and opposite ends of the bottom surface side arcuate part and the side arcuate parts on both sides are connected by lower connection surfaces, and the packing has a maximum width between the side arcuate parts on both sides. An angle formed by a segment which connects a peak on the top surface arcuate part and a lowermost point of the bottom surface side arcuate part, and a vertical line passing through the lowermost point, is formed as an outward or inward inclination with respect to the annular shape.
