<p>PROBLEM TO BE SOLVED: To prevent a situation where an oil passage for feeding charge oil from a charge pump 10 into a hydraulic oil passage 142 of an HST type continuously variable transmission contacts another object and breaks or causes oil leakage by breaking, and to reduce a component cost and an assembly cost by reducing the number of components needed to form the oil passage. SOLUTION: A first charge oil passage d formed in thickness of a transmission casing 106a is provided so as to extend a charge oil outlet hole 107b of the charge pump 107. A second charge oil passage f formed in thickness of an HST casing 106a is provided so as to communicate the first charge oil passage d with the hydraulic oil passage 142.</p> |
