PROBLEM TO BE SOLVED: To provide a V-belt type continuously variable transmission 10 which is inexpensive while having two or more characteristics of speed change.SOLUTION: A solenoid type actuator 50 is adopted for an actuator. An on-off controlled solenoid type actuator 50 is adopted, and the solenoid type actuator 50 is much more inexpensive compared to a servo motor. Furthermore, a control part and a ball screw are not needed. Thus, there is provided a V-belt type continuously variable transmission 10 which is inexpensive while having two or more characteristics of speed change. |
