Claims

[Claims for Utility Model Registration] A chain constituted by a group of mutually parallel link plates connected in an endless ring shape by pins, and a square-shaped through hole into which the link plates are inserted. and a V-shaped block that is attached to the chain so as to pass through the chain and is compressed in a V-groove of a pulley, and is wound between a plurality of pulleys to transmit power, positioning the V-shaped block between the pins by engaging the end of the link plate on the outer peripheral side in the pulley radial direction with the V-shaped block sandwiched therebetween;
A pair of protrusions on the outer circumferential side that prevent relative movement in the belt longitudinal direction between the V-shaped block and the chain are provided in a protruding manner, and the pin is attached to the link plate in a state in which the pin extends longitudinally through the link plate in the belt width direction. The belt has a length that projects outwardly from the plate, and the V-shaped block and both ends of the pin adjacent to both sides thereof are brought into contact with each other in the longitudinal direction of the belt. chain belt.
