US Patent 7691019 Chain guide

A chain guide, including a chain guide member and a guide holder, in which deformation and/or scarring of the guide holder can be controlled, and which is easy to assemble and disassemble, is described. The position of a front end of the guide holder is brought in contact with a flange provided at the front end of the chain guide member. Left and right side surfaces of the chain guide member are formed on the backside of the flange. The leading edge of the front end of the guide holder abuts and confronts the left and right side surface of the backside of the flange of the chain guide member so that a chain entering the chain guide contacts the chain guide member rather than the guide holder. A method of manufacturing the guide holder is presented.
