PROBLEM TO BE SOLVED: To provide a tank capable of maintaining a stable convection with a bubble flow.SOLUTION: A trunk part 30 mounted on a vehicle includes: a top trunk part 31; a bottom trunk part 32; and a pair of side trunk parts 33X and 33Y which are integrally formed with the top. The top trunk part 31 is formed at a top curvature Ra; the bottom trunk part 32 is formed at a bottom curvature Rb; and the side trunk parts 33X and 33Y are formed at a side curvature Rc. The top curvature Ra is arranged to be larger than the bottom curvature Rb. The side curvature Rc is formed with a one or plural curvatures. Plural air releasing openings 53 are disposed to generate a bubble flow with air bubbles floating up from the air releasing openings 53. After floating up on the surface of a liquid, the bubble flow is divided into a first bubble flow oriented to one side trunk part 33X: and a second bubble flow oriented to the other side trunk part 33Y. The flow direction of the first bubble flow X is changed to a flow oriented to the bottom trunk part 32 by the one side trunk part 33X; and the flow direction of the second bubble flow Y is changed to a flow oriented to the bottom trunk part 32 by the other side trunk part 33Y.

    【課題】気泡流による安定した対流を維持することができるタンクを提供すること。【解決手段】胴部30は、車両搭載時において、天面胴部31と、底面胴部32と、天面一対の側面胴部33X、33Yとを有し、天面胴部31を天面曲率Ra、底面胴部32を底面曲率Rb、側面胴部33X、33Yを側面曲率Rcで構成し、天面曲率Raを底面曲率Rbよりも大きな曲率で構成し、側面曲率Rcを1つ又は複数の曲率で構成し、複数の散気用開口53の配置によって、散気用開口53から浮上する気泡流を発生させ、気泡流は、液状物の水面に浮上した後に、一方の側面胴部33Xに向かう第1の気泡流と、他方の側面胴部33Yに向かう第2の気泡流とに分離し、第1の気泡流Xは、一方の側面胴部33Xにおいて底面胴部32に向かう流れとなり、第2の気泡流Yは、他方の側面胴部33Yにおいて底面胴部32に向かう流れとなることを特徴とする。【選択図】 図3
