Abstract
In an assembly of a toroidal continuously variable transmission, a sheath member ( ) is temporarily fitted on a male screw ( A) so that a step between a spline part ( A) and a male screw ( A) of a CVT shaft ( ) does not catch on an output disk ( ) when the CVT shaft ( ) is passed through the output disk ( ). The outer diameter of the sheath member ( ) is gradually reduced in a tapering shape from an outer diameter equal to that of the spline part ( A).
