A toroidal-type continuously variable transmission, has first and second disks respectively including inner surfaces; power rollers interposed for transmitting power; a pressing device for pressing the first disk toward the second disk; a main oil pressure control unit for non-electrically detecting the power for setting, as a target value, an oil pressure necessary for the pressing device when a transmission ratio between the first and second disks is a transmission ratio requiring a maximum pressing force, and increase the target value as the pressing force increases; an oil pressure correcting apparatus for electrically finding a necessary value of the oil pressure, the necessary value corresponding to the optimum value of pressing force generated by the pressing device, and also for introducing an oil pressure of a value into the pressing device, the oil pressure of the value being obtained by subtracting a correction value from the target value.
