Claims

[Claims for Utility Model Registration] (1) In a chain-type steel belt in which a link is attached to a V block that is wrapped around a V-shaped pulley and makes frictional contact with the V-shaped pulley, the V-block is divided. A guide consisting of two block pieces, with an elastic body interposed between the links constituting the chain so that both the block pieces can be extended in the longitudinal direction, and the block pieces can be expanded and contracted in the longitudinal direction. A low-noise steel belt characterized by having a (2) The low-noise steel belt according to claim 1, which is a utility model, and has a bush attached to the outer periphery of both block pieces as the guide portion. (3) A utility model in which a pin is protruded from one contact surface of the block piece as the guide part, a guide hole is formed in the other contact surface, and the pin is slidably inserted into the guide hole. A low-noise steel belt according to claim 1. (4) Low noise according to claim 1 of the utility model registration claim, in which a guide hole is formed in the contact surface of both block pieces as the guide part, and a pin with a sliding tolerance is inserted into the guide hole. steel belt. (5) The low-noise steel belt according to claims 1 and 2, wherein the elastic body is located between the links and is interposed between one end of the bushing and the inner link. (6) The elastic body according to claim 1, 2, 3, or 4 of the utility model registration claim, in which the elastic body is positioned between the links and is interposed between the contact surfaces of both block pieces.
