The one shown in 0 is known. That is, the continuously variable transmission 1
Input shaft 2 (engine output shaft or shaft connected thereto)
And an output shaft 3, transmission pulleys 4 and 5 mounted on the shafts 2 and 3, respectively, and an endless V belt 6 mounted on the pulleys 4 and 5.

One pulley body 7 is fixed to the input shaft 2, and the other pulley body 8 is non-rotatable relative to the input shaft 2 and is movable in the axial direction. As a result, the weight roller 9 is moved outward in the radial direction, whereby the movable pulley body 8 is moved closer to the fixed pulley body 7.

And a spring 13, and one pulley body 11
Is fixed to the output shaft 3, the other pulley body 12 is non-rotatable relative to the output shaft 3 and movable in the axial direction, and the movable pulley body 12 is constantly pressed by the spring 13 in the direction of the fixed pulley body 11, It is getting closer.

定プーリー７から離間せしめられる。According to this continuously variable transmission 1, when the input shaft 2 is stopped or started to rotate, the state shown in FIG. 7 is obtained. That is, as shown in FIGS. 9 (a) and 10 (a), the movable pulley body 12 on the output shaft 3 side is pushed toward the fixed pulley body 11 side by the spring 13 and comes closer to each other.
The belt 6 is moved toward the outer peripheral end of the transmission pulley 5,
Since the V-belt 6 pushes the tapered surface 8A of the movable pulley body 8 of the transmission pulley 4 on the input shaft 2 side in the axial direction and moves toward the inner peripheral end, the movable pulley body 8 of the pulley 4 is separated from the fixed pulley 7. To be

なる。Therefore, when the engine is started or at low speed operation (idling), the rotation speed of the output shaft 3 is smaller than that of the input shaft 2, and a large reduction ratio can be obtained. When the engine speed gradually rises from the state of FIG. 7 and the number of rotations of the input shaft 2 increases, the weight roller 9 built in the transmission pulley 4 is centrifugally generated by the weight roller 9 outward in the radial direction, that is, the outer peripheral end of the movable pulley body 8. Direction, and the centrifugal force of the weight roller 9 becomes larger than the urging force of the spring 13 that presses the output shaft 3 side pulley 5, and the input shaft 2 side transmission pulley 4 moves as the rotational speed increases. The distance between the two pulley bodies 7, 8 becomes narrower, and the state shown in FIG.

位置が常に変化するようになっている。On the other hand, in the transmission pulley 5 on the output shaft 3 side, the distance between both pulley bodies 11 and 12 is widened, and the pulley diameter is substantially reduced as shown in FIG. The rotation of 3 increases and the number of rotations increases. That is, the state shown in FIG. 8 is obtained. In this way, the changes in the transmission pulleys 4 and 5 are always in tune with the engine speed, and even if the output pulley 3 stops immediately after the rotation speed of the output shaft 3 increases, the transmission pulley 4 of the V-belt 6 may be stopped. The position with respect to 5 is always changing.

There was a problem with the response to the rotation speed of the input shaft 2, and therefore there was a problem with maneuverability.
