Abstract
In a toroidal type continuously variable transmission, a pair of power rollers are operatively interposed between input and output discs. Each power roller includes a power inner roller frictionally engaged with the input and output discs, a power outer roller receiving an axial load applied to the power inner roller from the input and output discs, a ball bearing operatively interposed between the power inner and outer rollers and a shaft receiving a radial load applied to the power inner roller from the input and output discs. The shaft is a one-body member comprising a first shaft portion on which the power outer roller is coaxially and tightly disposed and a second shaft portion on which the power inner roller is coaxially and rotatably disposed. The power outer roller and the shaft are produced separately. Upon assembly, these two parts are coupled together to constitute an integrated unit.
