PROBLEM TO BE SOLVED: To provide the oil passage structure for a continuously variable transmission, reducing concentration of stress to an oil passage of a boss part of a piston. SOLUTION: A fitting part 118 fitted in an output shaft 48 is provided with an oil passage 116, and an end surface 120 corresponding the oil passage 116 is provided with a recess 122. The output shaft 48 is positioned in the continuously variable transmission 16 by a nut 124 through a driven side bearing 53, and a driven side piston 108 is fixed to the output shaft 48, with the end surface 120 made adjacent to the driven side bearing 53.
