ABSTRACT:
A V-belt transmission is provided which comprises two pulleys, an endless metallic V-belt operatively positioned between the two pulleys, a plurality of V-shaped members positioned with the V-belt located between the arms of the V and a stopper member for engaging the V-shaped member to prevent the V-shaped member from coming off of the V-belt. The V-shaped member includes grooves in a wall of the arms of the V at a position below or inside the plane of the inner surface of the V-belt. Further, the stopper member includes a middle portion which is positioned above or outside the plane of the outer surface of the V-belt and end portions for engaging the grooves at a point below or inside the plane of the inner surface of the V-belt. The groove in the V-shaped member is located on the outside of the arms of the V and has a first portion which extends in the lengthwise direction of the V-belt and a second portion which extends perpendicular to the surface of the V-belt. The end portion of the stopper member has first and second portions, the first portion engaging the first portion of the groove and the second portion engaging the second portion of the groove. The middle and end portions of the stopper member are integral.
