An object of the present invention is to provide a chain reducing friction caused by sliding between the pin and the inner plate, whereby durability is improved, a frictional loss is reduced, and the reduction in size and cost can be implemented. In a silent chain, a guide row and a non-guide row, which are adjacent to each other in a longitudinal direction, are connected together in a bendable manner using a single pin movably inserted into a second pinhole of an inner plate. A hole peripheral wall surface forming the second pin hole has a plate rolling surface, and an outer peripheral surface of the pin has a pin rolling surface. During chain bending, the plate rolling surface rolls on the pin rolling surface. |

1. A chain comprising: a plurality of first links; a plurality of second links; and a plurality of pins, the first link including a pair of holding plates, the second link including one or more inner plates disposed between the pair of holding plates in a width direction, the first link and the second link adjacent to each other in a longitudinal direction being coupled together in a bendable manner via the single pin movably inserted into a pin hole in the inner plate and held in a state where rotational movement of the pin is regulated by the pair of holding plates, the chain being wound around one or more rotary wheels, wherein
a hole peripheral wall surface of the inner plate forming the pin hole has a plate rolling surface, an outer peripheral surface of the pin has a pin rolling surface, and the plate rolling surface rolls on the pin rolling surface during chain bending in which the second link bends relative to the first link. |
