To possess the cryogenic liquid case (1) for the supporting part (10) for having the storage tank (5) for engaging the bottom (5a) that multiple bottom plates (5a1) form and supporting bottom, supporting part possesses：Lateral branch support part (11), it supports the edge part of the storage tank of the side wall comprising storage tank；Medial support portion (12), it includes by being given load and the heat-barrier material (4b1) of creep and being configured at the inner side of lateral branch support part, the initial stage of the upper surface in medial support portion is highly set as, in the life expectancy of cryogenic liquid case, the allowable bending stress that the maximum stress in bend on bottom plate is no more than bottom plate is acted on by the difference of the height of the upper surface in medial support portion and the height of the upper surface of lateral branch support part. |
