Claims

[Claims for Utility Model Registration] (1) A pair of rotating shafts arranged parallel to each other,
A fixed sheave is rotatably fixed to each of the rotating shafts and fixed so as not to be movable in the axial direction; A pair of variable pulleys consisting of a movable sheave forming a belt groove, a transmission belt wound between the belt grooves of both variable pulleys, and a movable sheave of each of the variable pulleys moved toward and away from a fixed sheave. A pair of speed change mechanisms that change the pulley diameter of the variable pulley, and a pair of speed change mechanisms that are interlocked so that the pulley diameters of both variable pulleys change in opposite directions to vary the speed ratio between the two rotating shafts. What is claimed is: 1. A pulley type transmission, comprising: a speed change switching mechanism, the speed change switching mechanism comprising a buffer means for absorbing vibrations transmitted between the two speed change mechanisms. (2) The transmission mechanism has a cylindrical cam and a cam follower that contacts the cam surface of the cylindrical cam, and one of the cylindrical cam and the cam follower is rotatable around the rotation axis, and the cylindrical cam and the cam follower are The speed change switching mechanism is configured to move the movable sheave in the axial direction by relative rotation, and includes a straight rod-shaped link connected to the movable sheave of one variable pulley;
a ball joint connected to a movable shaft of the other variable pulley and slidably supported by the link, and the buffer means limits relative movement between the ball joint and the link. 2. The pulley type transmission according to claim 1, wherein the pulley type transmission is a spring arranged as shown in FIG.
