PROBLEM TO BE SOLVED: To provide a belt type stepless speed-changing mechanism capable of reducing the energy which is consumed by a speed-changing actuator at the acting time of a speed changer and which can suppress the energy to be consumed by the speed-changing actuator in accordance with the increase in the capacity of the speed-changing mechanism even in the case the capacity of the speed changing actuator increases.SOLUTION: A secondary pulley 250 is equipped with a first elastic member 20 for clamping a V-belt 211, and a primary pulley 200 is arranged with a second elastic member 18 for applying a biasing force against the first elastic member so that the second elastic member is made to rotate together with the primary pulley. |
