Continuously variable transmission

A continuously variable transmission comprising:

• a transmission shaft that serves as a center of rotation;
• first to fourth power transmission elements that have a first rotation center axis coaxial with the transmission shaft, and configured to be relatively rotatable with one another in a circumferential direction;
• a plurality of rolling members that has a second rotation center axis, is disposed radially around the first rotation center axis, and further on an outer peripheral surface of the third power transmission element, is interposed between inner peripheral surfaces of the first and second power transmission elements, which are disposed to face each other, and further, is held by the fourth power transmission element in a freely tilting manner;
• a transmission device configured to change a gear ratio between an input side and an output side by tilting each of the rolling members;
• a rotary shaft that is coupled with one of the first and second power transmission elements, and is provided with a cylindrical section that covers the first to fourth power transmission elements, and the rolling member from an outer side in a radial direction;
• an annular member that is coupled with the rotary shaft, and configured to form an annular oil reservoir formed of lubricating oil along an inner peripheral surface of the cylindrical section during operation;
• and
• a scraping up section that is disposed between the first power transmission element and the second power transmission element, further, on an inner side in the radial direction than the inner peripheral surface of the cylindrical section, and further, on the outer side in the radial direction than the plurality of rolling members, and configured to scrape up the lubricating oil by rotating in the circumferential direction.
