A timing chain structure is provided to decrease the number of extra chain link for the assembly of sprockets, thereby reducing weight and production costs of the timing chain structure. A timing chain structure comprises: a connection chain(70) mounted in the middle of a chain(100); and a chain link held by a sprocket. The connection chain consists of an inner connection chain(30) and an out connection chain(50). The inner connection chain is composed of: an inner plate(31) arranged on both sides of the inner connection chain; and a bush installed between the inner plates. The inner plate includes a first penetration hole connected to a fixing pin of an out plate(60) and a second penetration hole with an opening formed therein. |
