Abstract
A chain includes a chain unit. The chain unit includes a pair of first and second plate units, a link pin extending in an inner-to-outer direction, and a protective member. Each of the first and second plate units includes two chain plates adjacent to and arranged in the inner-to-outer direction and having an inner side surface. The inner side surfaces of the first and second plate units face each other. The link pin interconnects the plate units to define a between-plate space between the inner side surfaces of the first and second plate units. The protective member extends integrally from the topside of at least one of the chain plates of the first chain plate, is spaced apart from the second chain plate, and has a shielding portion for covering at least a portion of an upper end of the between-plate space.
