PROBLEM TO BE SOLVED: To provide a lubricating device, capable of using an annual gasket without the risk of gasket deterioration and the risk of oil leak from a lubrication chamber. SOLUTION: This lubrication device is for lubricating a component in a turbo machine, especially a shaft bearing in a turbojet. The lubrication device is provided with an annular support part to define a lubrication chamber around the component, an annular cover installed in a sealed state on the part, including a lubricating oil inlet, and an annular channel to let flow of air for pressurization and cooling to pass. The annular channel is formed between the part and the cover, and communicated with a duct in the support part and an annular enclosure formed in a cover for letting air for pressurization and cooling to pass.
