    摘要： 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.

    摘要： A vehicular drive system switchable between a continuously-variable and step-variable shifting states, and a control device for controlling the vehicular drive system so as to reduce a shifting shock of an automatic transmission included in the drive system, which takes place due to an overlap control involving a switching control of the drive system and a shifting control of the automatic transmission.Execution-timing control means 82 is provided to command switching control means 50 and step-variable shifting control means 54 to sequentially execute a switching control by the switching control means to switch transmission mechanism 10 between an electrically established continuously-variable shifting state and a step-variable shifting state, and a shifting control by the step-variable shifting control means to shift an automatic transmission portion 20, even when an overlap control involving the switching control and the shifting control is required, whereby the switching and shifting controls can be rapidly completed. Since the transmission mechanism 10 is not switched during the shifting control of the automatic transmission portion 20, the input speed of the automatic transmission portion 20 will not change due to the switching control, apart from a change of the input speed as a result of the shifting control, making it possible to prevent the complicated shifting control and reduce the consequent shifting shock.
