Abstract
A chain, wound to span between two pulleys each having facing conical surfaces able to change a distance therebetween and sandwiched by the facing conical surfaces, includes: link units each configured such that plate-shaped links, each having openings, are oriented in a chain circumferential direction and arranged in a chain width direction; and pins each extending through the openings of the links of the link units adjacent in the chain circumferential direction and each contacting the conical surfaces of sheaves at both ends thereof. A curvature radius of a shape curve representing a shape of each end face of each pin in a plane perpendicular to the chain circumferential direction is larger at an inner side in a pulley radial direction than at an initial contact point that is a contact point at the time when a load on each pin is 0.
