摘要： A piston is displaced in a cylinder to pre-load an antifriction bearing. This displacement of the piston is effected according to the amount of working oil confined in a working oil chamber. This oil pressure generating device is equipped with a working oil reservoir to pressurize the working oil in the reservoir for reserving the working oil to be fed to the chamber. An orifice is disposed in a working oil passage for providing the communication between the reservoir and the chamber. The clearance, which is established in the portion of antifriction bearing by the extension or contraction of a shaft due to a temperature change, is absorbed by such displacement of the piston, as is effected by the flow of the working oil between the reservoir and the chamber via the orifice. This orifice acts as a high resistance to and a high rigidity against the abrupt fluctuation in the direction opposite to the pre-loading direction.
