Abstract
Using a phase matching device 59, the phases of the outside diameter side and inside diameter side ball spline grooves 46, 47 are matched to each other and such phase matched state is maintained as it is. A given number of balls are supplied to between the two ball spline grooves 46, 47 through openings formed in the upper end portions of spaces existing therebetween by a ball supply device 64. An input shaft 15 and an input side disk 2B are shifted reciprocatingly with respect to each other in the axial direction thereof and in the circumferential direction thereof using a lift board 54, a center pin 56, and a swing device 72. As a result of the relatively shifting operation of the input shaft 15 and input side disk 2B, the balls are allowed to drop into the lower portions of spaces respectively defined by and between the two ball spline grooves 46, 47 due to the influence of gravity, that is, due to their own weights.
