Abstract
A rotary machine includes a rotor, a rotating shaft fixed to the rotor, and a balance weight fixed to the rotor. The balance weight has a balance part fixed to the rotor and not contacting the shaft, a locking part, a shaft abutting part, and a coupling part coupling the balance part and the shaft-abutting part, The locking part is disposed on a side of the shaft opposite from the balance part. The locking part is locked with the shaft to limit movement of the balance part along a direction of centrifugal force. The shaft-abutting part is positioned between the shaft and the balance part, is coupled with the locking part, and contacts the shaft. A length of the locking part along a rotor radial direction is shorter than a rotor radial distance between the shaft and the balance part. The shaft-abutting part is radially shorter than the locking part.
