A cantilever type screw compressor directly connecting a motor has a damping structure, which is inability of generating unbalanced force during rotation of a rotor shaft and directly minimizes vibration of the rotor shaft itself. The screw compressor (1) comprises a screw rotor (41); a screw housing (12) for housing the screw rotor (41); a motor shaft (7) integrally formed with the screw rotor (41) and supported by a cantilever at the screw rotor side; and a motor which rotates the motor shaft (7). The screw compressor (1) comprises a damping component portion having a plate-shaped weight (8) which is substantially coaxial to the motor shaft (7) in a manner of colliding with surrounding components or mutual collision. The natural vibration frequency of the weight is identical to that of the rotor shaft (11). |
