Abstract
A lubricating structure for a hydrostatic continuously variable transmission. The structure includes an oil path arranged at an outer circumferential side of a clutch valve, and a lubricant oil ejection hole communicating with the outer circumferential side oil path of the clutch valve and formed in the transmission shaft toward the outer circumference of the transmission shaft. In addition, the structure includes a communicating oil path that is also formed in the transmission shaft for communicating between an oil feeding passage communicating with an lubricant oil feeding source and the outer circumferential oil path of the clutch valve. A single orifice is arranged in the communicating oil path, rather than in the lubricant oil ejection hole. This configuration provides for efficient manufacturing and a high degree of freedom in setting of the lubricant oil ejection hole.
