Claims

[Scope of utility model registration request]

In a fluid machine casing that is divided by a dividing plane that includes a rotor shaft, a holder of a bearing device that supports the rotor shaft is brought into contact with and fixed to the outer surface of the end wall through which the rotor shaft passes, and the holder of the bearing device that supports the rotor shaft is fixed to the outer surface of the end wall through which the rotor shaft passes. A cover that covers the holder is removably fixed to the outer surface of the end wall, and an oil hole drilled in the end wall by machining is opened in a surface of the end wall that comes into contact with the holder. A casing for a fluid machine, characterized in that an oil hole bored in the holder and communicating with the bearing is opened in a contact surface of the holder to the end wall so as to be aligned with the opening.
