Power transmission chain and power transmission device

摘要

A power transmission chain is provided with a plurality of connecting members that connect a plurality of links to each other so as to be bendable. Each connecting member includes a power transmission member opposed to a predetermined counterpart member. The counterpart member includes either a member interposed between the power transmission member and the corresponding link or the corresponding link. Opposed portions of the power transmission member and the counterpart member contact each other at a contact portion that is displaced as a result of bending between the links in a contact condition including at least either a rolling contact or a sliding contact. The opposed portion of the power transmission member has a convex curve portion. The opposed portion of the counterpart member has a concave curve portion to be engaged with the convex curve portion.
