PURPOSE:To prevent circulating oil from falling and improve efficiency of transmission, by supporting a casing or output shaft with a bearing housing, preventing an outflow of working oil in a rake pipe chamber to the outside with a cut groove and providing the cut groove to said bearing housing. CONSTITUTION:If working oil is fed between an impeller 1 and a runner 2 in a working chamber 9 from an oil pump, kinetic energy between the impeller 1 and the runner 2 transmits power from an input shaft 3 to an output shaft 4. Here the working oil, flowing from the working chamber 9 into a rake pipe chamber 10, tends to flow out to the outside from a gap H, between a casing 11 and bearing housing 8, however the working oil can be prevented from flowing out by a cut groove 14 formed in the peripheral surface of the bearing housing 8 at a side of the output shaft 4. Accordingly, a quantity of the working oil in a circulative circuit is prevented from decrease by falling, thus a minimum requirement flow of the working oil can be maintained. |
