PROBLEM TO BE SOLVED: To provide a lubrication structure of a belt type continuously variable transmission for improving the straight advancement of the injected and supplied lubricating oil while suppressing the diameter dimension of a lubricating oil supply pipe to be small.SOLUTION: A lubricating structure includes a lubricating oil supply pipe 30 disposed between a drive pulley 5 and a driven pulley 7. The lubricating structure includes first and second oil spray passages 51 and 61 for injecting and supplying the lubricating oil toward the drive pulley 5 and driven pulley 7 disposed in the lubricating oil supply pipe 30. The first oil spray passage 51 includes a first injection port 53 opening toward the drive pulley 5 side in a side surface of the lubricating oil supply pipe 30, and a first in-flow port 52 opening toward the upstream side of the flow of the lubricating oil in the lubricating oil supply pipe 30. The second oil spray passage 61 includes a second injection port 63 opening toward the driven pulley 7 side in a side surface of the lubricating oil supply pipe 30, and a second in-flow port 62 opening toward the upstream side of the flow of the lubricating oil in the lubricating oil supply pipe 30. |
