PROBLEM TO BE SOLVED: To provide a fuel gas compressor capable of reducing a burden on a worker engaging in removing work by preventing the fixing of a wing joint of a moving blade and a blade groove of a disk, reducing a burden on the disk and the moving blade, and, furthermore, improving an operation rate by shortening operation time.SOLUTION: A fuel gas compressor includes a moving blade 23 having a moving blade body and a wing joint 55, and a disk 26 disposed on a rotor shaft having a blade groove 58 with which the wing joint 55 engages. Sulfurization-preventive coating layers 59 and 69 having heat resistance to the working temperature are formed on at least either the surfaces 56 and 58 of the wing joint 55 or the surfaces 66 and 67 of the blade groove 58 opposed to each other. |
