Abstract:
A method of manufacturing a sprocket segment that is formed by forging as one of a plurality of circumferentially divided parts of a sprocket having a plurality of teeth arranged on an outer peripheral surface of a circular flange, the method includes: forming a material of the sprocket segment into an initial formed state in an initial forming step; and subjecting the sprocket segment in dies to a finish forming process with a tooth trace direction of the sprocket segment as viewed in cross-section of the sprocket segment being inclined relative to a forging direction of the dies in a finish forming step.
