The lower tank half body includes: a lower tank main body portion that is elongated in a direction parallel to a reference plane including joint surfaces of lower and upper planar flange portions as parts of the lower and upper joint flanges, respectively, includes, along a longitudinal direction thereof, a narrow portion narrower on one side than the other side, and bulges toward a lower side from the reference plane; and a pair of expansion tank portions that are disposed on opposite sides of the narrow portion as seen in a plan view from a direction orthogonal to the reference plane, formed to be shallower than the lower tank main body portion, and bulge downward from the reference plane.
