A V-pulley of variable pitch type for a drive acting through a tension medium strand includes two sheaves, at least one of which is displaceable in an axial direction relative to the other, each sheave having a running surface for a tension medium strand such as, for example, V-belts, at least one of the sheaves being mounted on a shaft-like member, at least two systems having means mutually connecting the sheaves to each other, the at least two systems being axially spaced from each other. Thus at least one system allows axial displacement of the one sheave linked thereto, and the other system is firmly linked to the other sheave. Two linked portions of the systems are located radially outside with respect to the running surfaces of the sheaves, thereby obtaining friction-free and wear-free entrainment and guidance of the movable sheave, and especially entrainment and guidance without the occurrence of fatigued corrosion to link means.
