摘要： Fletching wear caused by elastic deformation in the axial direction of an input-side disk 2c due to thrust force of a pressure device is prevented. A female-spline section 13a formed around the middle section in the axial direction of the inner-circumferential surface of a center hole 19 in the input-side disk 2c and a male-spline section 12a formed around the outer-circumferential surface of one end section in the axial direction of an input rotating shaft 1b engage with a spline engagement. A disk-side fitting surface section 22 formed around a portion of the inner-circumferential surface of the center hole 19 in the input-side disk 2c that is adjacent to the other end side of the female-spline section 13a and a shaft-side fitting surface section 23 formed around a portion of the outer-circumferential surface of the input rotating shaft 1b that is adjacent to the other end side of the male spline section 12a are fitted together with an interference fit.
