Abstract: Disclosed is a corner structure (100) of a liquefied gas storage tank, wherein the corner structure is installed at a corner of a storage tank for loading liquefied gas and supports sealing walls (51, 52) that prevent leakage of the liquefied gas. The corner structure (100) may include: two insulation members (110) arranged on the inner surface of a hull structure so as to be oriented in different directions; and mobile members (130) which are installed on the respective insulation members (110) and to which the sealing walls (51, 52) are joined. The mobile members (130) may be slidably coupled to the insulation members 110, and a plurality of the mobile members (130) may be arranged spaced apart from each other in a straight line on one of the insulation members.
