PROBLEM TO BE SOLVED: To stably maintain both functions of a self stabilizing function and an automatic aligning function over a long period by applying error compensation and function adjustment to an elastic body pressurizing force, while an electric body has the above two functions at a friction transmitting surface of the transmitter, the former being for instantaneously moving from an oscillating state to a stable state by elastic absorption and elastic pressurization against an excessive pressurization and pressurization shortage between a driven wheel and a transmission body, the latter being for self searching and setting the velocity ratio of contacting radiuses of the driven wheel and the transmission body, imparting a desired pressurizing force to restore and keep tension. SOLUTION: The control device is provided with a pressurizing device for applying elastic pressurizing force generated by compressing the elastic body by a compression device to the driven when pressure-controlling a transmission wheel through the elastic body, a pressure detector for obtaining a detected value of elastic pressurizing force, operating device for optionally producing pressurizing force, and a controller for always calculation the deviation between a selection value of predetermined pressurizing force and the detected value. The controller achieves pressure error compensation generated on the elastic body and strengthening and adjustment of the additional function by program control. |
