A turbo compressor includes: multiple stages of compression devices arranged in series with respect to a gas passage, each of the compression devices including an impeller that rotates about an axis; an oil tank capable of supplying lubricating oil to a sliding portion of the compression devices; a partitioned intermediate space formed to communicate with the gas passage on an upstream side of the compression devices via gaps between the partitioned intermediate space and the gas passage; and a pressure equalizer provided to continuously connect the partitioned intermediate space and the oil tank.
