Abstract
A chain for a V-pulley which is used by being endlessly trained between a pair of V-pulleys and in which blocks each having an end surface for coming into contact with the V-pulley are respectively disposed on the outer sides of outer link plates. The end surface of the block is formed into a convex surface constituted by the whole or part of a conical surface which has substantially the same apex angle as that of the inner wall of the V-pulley and has an axis parallel to the axis of a connecting pin. The block may be fixed with respect to the outer link plate or may be made rotatable about the axis of the cone.
