PURPOSE:To reduce stress produced at a coupling point by forming a coupling point where temperature conditions are uniformalized in a coupling portion of a tank main body to a support member so as to change the state of deformation when the tank main body is contracted. CONSTITUTION:The temperature of a coupling portion 2c of a support member 11 is made substantially equal to that of a tank main body 10 by a thermal conductive member 2. A temperature gradient curve portion is formed between the portion 2c and a coupling point 11c, and the temperature gradient below the portion 2c sufficiently cancels stress produced at the coupling point 11c portion by contraction. Therefore, the occurrence of stress can be considerably removed at an important coupling point 11e portion. |
