Claims

[Claims for Utility Model Registration] The first link plate is constructed by connecting a plurality of link plates in an endless ring shape by pins, and the first link plates are arranged in parallel in the width direction with the phase shifted from each other by half the pitch of the pins. a pair of chains, comprising a chain, a second chain, and a first V-shaped block and a second V-shaped block positioned approximately at the longitudinal center of the ring plate and attached to the first chain and the second chain in a relatively immovable manner, respectively; In a chain belt that is wound between pulleys to transmit power, a through hole sufficiently larger than a cross section of the pin is provided approximately at the center in the longitudinal direction of the link plate, and the first V-shaped block and the second V-shaped A fitting hole into which the pin can fit is provided approximately in the center of each block in the thickness direction, and the pin of the second chain is passed through the through hole of the link plate of the first chain into the fitting hole of the first V-shaped block. and a pin of the first chain is fitted into a fitting hole of the second V-shaped block through a through hole of a link plate of the second chain.
