PURPOSE:To prevent oil deterioration and oil caulking caused by increase of an oil temperature in a device wherein a power turbine shaft of a gas turbine engine is connected to a deceleration gear shaft provided with a gear for extracting an output of the power turbine shaft as a power by means of a coupling prepared by cutting a spline, in respect to an oil supplying structure for lubricating the coupling. CONSTITUTION:A substantially horn-like cover 12 is provided so as to extend from a bearing part 4a of a power turbine shaft 1 to a bearing part 5a of a deceleration bear shaft 2, and surround a coupling 3. Oil supplied to the coupling 3 lubricates a spline joint 3b, flows along the cover 12 to the bearing 5a of the deceleration gear shaft 2, to lubricate this part. |
