PROBLEM TO BE SOLVED: To suppress reduction of lubrication performance caused by influences of the gravity.SOLUTION: A continuously variable transmission includes: an non-rotatable shaft 60 including an axial center oil path 61; first and second rotary members 10 and 20 and a sun roller 30; a plurality of planetary balls 40; a carrier 50 which matches the center axis thereof to a first rotation center axis R1 and is fixed to the shaft 60; and an iris plate 80 in which the respective planetary balls 40 are leaned, and thereby changing a transmission gear ratio between input and output. The shaft 60 includes: a first radial direction oil path 62 for supplying a lubricant from the axial center oil path 61 to a lower side of a vehicle; and a second radial direction oil path 63 having a larger flowing area of the lubricant than that of the first radial direction oil path 62 for supplying the lubricant from the axial center oil path 61 to an upper side of the vehicle. The carrier 50 includes: a guide oil path 56 to which the lubricant in the first radial direction oil path 62 is supplied and on which the lubricant is discharged to the lower side of the vehicle or obliquely downward; and a guide oil path 56 to which the lubricant in the second radial direction oil path 63 is supplied and on which the lubricant is discharged to the upper side of the vehicle or obliquely upward. |
