ABSTRACT:
The plates of transmission chain for an engine are formed with a guide-contacting configuration composed of spaced flat surfaces that come into sliding contact with a flat chain guide, and convex surfaces, continuous with and between the flat surfaces, for sliding contact with a convex chain guide. The convex surfaces are connected by a concave surface that, with the guide surface, forms an oil-retaining clearance. The radius of curvature of the convex curved surfaces of the plate preferably increases gradually from the location where they meet the flat surfaces toward the location where they meet the concave surface. The plates can have the same configuration on the side facing the inside of chain loop as on the side facing the outside of the chain loop.
