And the rotation of the input shaft 91 can cause the plurality of balls 924 to push the sliding drive plate 922 to axially slide along the input shaft 91 by its centrifugal force, and the drive plate spring 943 pushes the sliding drive plate 942 with its elastic force. The shaft 93 is axially slidable.

However, the conventional mechanical V-belt stepless shifting structure mostly uses parameters such as a ball counterweight and a spring force of a drive disc spring to achieve a desired specific shift mode, and therefore, only a single shift can be set. mode.
