ABSTRACT:
A V-belt type continuous speed change mechanism including a stationary disc secured to the driving shaft and a movable disc axially slidable with respect to the shaft. The discs define a circumferential groove of a V-shaped configuration with which a V-belt is engaged. The movable disc is formed at its back side with slider accommodating recesses of a circular cross-section extending in parallel with the shaft. A slider is received in the recess for rotation about an axis parallel with the driving shaft and has a groove extending in parallel with the driving shaft. A spider secured to the driving shaft has radial arms each of which is fitted at an end to the long groove in the slider.
