PURPOSE:To enable the number of revolutions of an engine to rationally coincide with a car speed, by installing a holding means which reduces a moving force in the middle of movement in the direction of diameter of belt-winding position so that a driven pulley is increased in a speed. CONSTITUTION:With a driven pulley 14 rotated, a weight 34 is moved in the direction of diameter by a centrifugal force, winding position of a blet 32 to the driven pulley 14 is moved outwardly in the direction of diameter, and a driven pulley 27 is increased in a speed. Steep and slow slopes 35a and 35b and a weight 34 form a holding means 40 which reduces a moving force for moving winding position in the middle of movement in the direction of diameter of winding position so that the driven pulley 27 is increased in a speed. With the aid of this means 40, the winding position is held in the middle of movement in the direction of diameter of the winding position once, and this obtains a car speed which coincides with the number of revolutions of an engine. |
