Patent Images
1. A device for passing an axial member of a toroidal continuously variable transmission through disks which have been prefitted in a housing, wherein said axial member comprises a step between a large diameter part and a small diameter part, comprising:
- a sheath member comprising a through hole through which said axial member passes, wherein a female thread is formed at least in a section of the inner surface of said through hole and wherein said female thread is screwable onto a male thread formed on an outer circumference of said small diameter part of the axial member, and an outer diameter of said sheath member gradually decreases from an outer diameter equal to that of said large diameter part.

Abstract
In an assembly of a toroidal continuously variable transmission, a sheath member (41) is temporarily fitted on a male screw (3A) so that a step between a spline part (21A) and a male screw (3A) of a CVT shaft (3) does not catch on an output disk (18, 20) when the CVT shaft (3) is passed through the output disk (18, 20). The outer diameter of the sheath member (41) is gradually reduced in a tapering shape from an outer diameter equal to that of the spline part (21A).
