A belt recess is formed in the block element for passing the belt element therethrough, having a contact surface which is brought into contact with innermost surface of the belt element. A rocking edge is provided for the block element, which comes into contact with an adjacent block element as relevant span portion of the belt assembly is wound around the pulley, causing a relative rocking motion of adjacent blocks. The block elements are constituted of no less than two kinds of block elements of mutually different radial distance between the contact surface of the belt recess and the rocking edge.
