In order to facilitate an assembling operation of a structure which is correctly operated with a proper positional relation, in a power roller unit for a toroidal type continuously variable transmission according to the present invention, a displacement shaft, a power roller, a radial needle bearing, a thrust ball bearing and a thrust needle bearing are pre-assembled to a trunnion. After dimensional relations and operation conditions of the constructural parts of the assembly or unit are ascertained, the assembly is assembled within a housing together with other unit, thereby completing the toroidal type continuously variable transmission. That is to say, according to the present invention, since the dimensional relations and operation conditions of the constructural parts can be ascertained in a condition such parts can easily be disassembled and re-assembled, a structure in which the positional relation between the constructural parts is maintained with high accuracy can be manufactured cheaply without any troublesome operations.
