ABSTRACT:
An automatic transmission case is formed with a power output shaft support hole including a bearing portion and a sealing portion, and is further formed with a lubricating oil supply hole. A power output shaft formed with an axial through hole and at least one radial hole for conducting lubricating oil is assembled into the power output shaft support hole. A sleeve formed with a circumferential groove in its outside surface is fitted closely over the power output shaft from the side of the sealing portion, and a seal ring is mounted and received in the circumferential groove and in contact with the second portion so as to seal the annular space in the power output shaft support hole around the power output shaft, the sleeve including an oil communication passage extending between the lubricating oil supply hole in the case and the radial hole in the power output shaft.
