Claims

[Scope of utility model registration request]

In a rotor of a fluid mechanism in which a rotor disk is sandwiched and integrally fixed to a rotating shaft, a plurality of pin holes passing through the contact surface between the adjacent rotating shaft and the rotor disk and the contact surface between two adjacent rotor disks are formed in the radial direction. A rotor for a fluid machine, characterized in that fixing pins are inserted into each of the pin holes, and slip-out prevention fittings are attached to each pin hole to prevent the fixing pins from coming off.
