PROBLEM TO BE SOLVED: To provide a liquid circulation device for circulating liquid between two spaces isolated from each other while stabilizing the amount of liquid in each space. SOLUTION: The liquid circulation device 1 is provided for circulating oil between the space 101 and the space 101 isolated from the space 201. The liquid circulation device 1 includes flow paths 122, 321 through which the oil is distributed from the space 101 toward the space 201, a pump 123 for transferring the oil from the space 101 to the flow path 122, flow paths 131, 331 through which the oil is distributed from the space 201 toward the space 101, and gas flow paths 112, 311 for ventilating the space 101 and the space 201.
