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.
