A power transmission chain (1) includes a plurality of link units (51, 52, and 53) aligned in the traveling direction of chain (X), and each link unit (51, 52, and 53) includes a plurality of links (2) aligned in the width direction of chain (W). Guiding members (12 and 13) are respectively provided correspondingly to connecting members (50) that link the link units (51, 52, and 53)' to one another in a manner so as to be bendable. Each link (2) includes first and second through-holes (7 and 8) aligned in the traveling direction of chain for inserting a corresponding connecting member (50) therethrough, and a communication groove (14) through which the first and second through-holes (7 and 8) communicate with each other. Each connecting member (50) includes first and second power transmission members (3 and 4). Either one of the first and second power transmission members (3 and 4) is guided by the guiding members (12 and 13), and consequently the one power transmission member comes into contact with the other power transmission member in a contact state including at least one of rolling contact and sliding contact.
