TOROIDAL TYPE CONTINUOUSLY VARIABLE TRANSMISSION

PROBLEM TO BE SOLVED: To prevent fretting wear based on axial elastic deformation of an input-side disc 2c by thrust of a pressing device.SOLUTION: A chamfered portion 18 is formed on an outer edge of a spline hole 12a of an input-side disc 2c. By making a radial length L of the chamfered portion 18 be larger than a depth d of each female spline groove configuring the spline hole 12a, an annular clearance gap 21 is formed between an inner side face of a locking ring 15 and a part adjacent to a radial outer side of an opening portion of the spline hole 12a, of an outer side of the input-side disc 2c.
