摘要： Lubricating oil passages extending toward a power transmission mechanism from a regulator valve to lubricate the power transmission mechanism include a first lubricating oil passage for supplying lubricating oil to a low clutch used to set up a low gear speed and a second lubricating oil passage for supplying lubricating oil with line pressure to the low clutch. A check valve for preventing the lubricating oil from flowing out from frictional engagement elements other than the low clutch when the second lubricating oil passage is selected, is provided on the first lubricating oil passage. An outflow preventing section for preventing the lubricating oil, supplied to the low clutch via the first lubricating oil passage, from flowing out from any open port of hydraulic control valves when the second lubricating oil passage is not selected, is provided on the second lubricating oil passage.
