Abstract

In a hydrostatic transmission (HST), a lubricating fluid passage is formed in an input shaft and has a pair of radially opposite lubricating fluid spill ports open at an outer peripheral surface of the input shaft. Both of the radially opposite lubricating fluid spill ports face a lubricated object of the HST. The lubricating fluid passage includes an axial fluid passage and a pair of radial fluid passages that are extended radially from the axial fluid passage to the outer peripheral surface of the input shaft so as to be radially opposite each other. Open ends of the respective radial fluid passages at the outer peripheral surface of the input shaft serve as the respective radially opposite lubricating fluid spill ports.
