Claims

[Scope of utility model registration request]

In a rocker pin type friction transmission chain in which both ends of a plurality of ring plates are endlessly connected by a pair of rocker pins and a large number of friction transmitting members are attached, each of the load transmitting surfaces of the pair of rocker pins is a convex load transmitting arc of a single curvature. The shape of the rocker pin insertion hole penetrating through the overlapping portions of both ends of the link plate is formed into a load transmitting circular concave surface having the same curvature and the same arc length as the load transmitting circular convex surface of the rocker pin on both end sides of the link plate. ,
The rocker pin sliding guide arc concave surface is formed on the center side of the link plate to have the same curvature as the load transmitting arc convex surface of the rocker pin and has a longer arc length than the load transmitting arc convex surface of the rocker pin, and the inner side of the link plate is formed on the inner side. The rocker pin is formed on a rocker pin non-slip abutment surface that does not bulge toward the edge, and the rocker pin non-slip surface and link that do not bulge toward the outer edge of the link plate on the outer side and abut against one rocker pin located on the end side of the link plate. A substantially cocoon-shaped plate is formed between the other rocker pin located on the center side of the plate and a continuous surface with an allowance surface having a clearance that allows the other rocker pin to slide toward the outer edge of the link plate. Rocker pin type friction transmission chain with continuous closed surface.
