In a chain transmission, the guide-contacting portions of inner and outer plates of a chain each comprise a pair of front and rear flat surfaces, an intermediate concave oil-retaining surface and convex connecting surfaces. The lengths of the flat surfaces are such that adjacent flat surfaces of overlapping inner and outer plates overlap even when the plates in contact with the portion of a convex guide surface having the smallest radius of curvature. |
