PROBLEM TO BE SOLVED: To reduce the lubricating oil quantity necessary to lubrication by changing the distribution of the lubricating oil quantity to an input shaft side variable speed pulley and an output shaft side variable speed pulley by transmission gear ratio. SOLUTION: When a primary pulley is slided to the transmission gear ratio- small side (high side), a pulley sensor shoe 21 slides to the right side in the drawing so that the passage inlet A1 of a lubricating oil feeding passage A for the primary pulley is largely opened, and the passage inlet B1 of a lubricating oil feeding passage B for a secondary pulley is small opened. Thus, the distribution of lubricating oil is performed so that the lubricating oil quantity fed into V grooves of the primary pulley through a pipe body 18 becomes larger, and the lubricating oil quantity fed into V grooves of the secondary pulley through a pipe body 20 becomes smaller. Further, when the primary pulley is slided to the transmission gear ratio-large side (low side), the distribution of the lubricating oil is performed so that the lubricating oil quantity fed into the V grooves of the primary pulley becomes smaller, and the lubricating oil quantity fed into the V grooves of the secondary pulley becomes larger. |
