<p>PROBLEM TO BE SOLVED: To ensure the amount of lubricant at a contacting portion while suppressing the increase of an agitation loss due to the lubricant.SOLUTION: A continuously variable transmission includes: a shaft 60; first and second rotating members 10 and 20; a sun roller 30; a carrier 40; a plurality of planetary balls 50; a transmission for tilting each planetary ball 50 to change a gear ratio between inputting and outputting; and a lubricant supplying device for supplying lubricant to contacting portions P1 and P2 between the first and second rotating members 10 and 20 and the planetary balls 50. The lubricant supplying device is disposed between the planetary balls 50 adjacent to each other on the inner side in a diametrical direction than inner peripheral surface 10a and 20a of the first and second rotating members 10 and 20 and on the outer side in the diametrical direction than an outer peripheral surface of the sun roller 30, and equipped with a nozzle member 91 having injection ports 91a and 91b turning to a supply destination of the lubricant.</p> |
