To provide such a toroidal type non-stage variable transmission as being capable of improving its power transmission efficiency and its life as much as possible.

This toroidal type non-stage variable transmission has variable speed units 2, 3 formed by mounting power rollers 23, 33 between each of input discs 21, 31 and each of output discs 22, 32 to be freely tilted. The discs 21, 22, 31, 32 are formed to flex as required with the inclination of the power rollers 23, 33 and properly contact power rollers 23, 33 during flexing. In this way, the lopsided contact of the power rollers 23, 33 with the discs 21, 22, 31, 32 is avoided in variable speed operation, e.g.
