Abstract
A sprocket wheel has an annular shape. The sprocket wheel has a plurality of projections formed on an outer peripheral surface for transmitting a driving force to a track. The sprocket wheel includes a base made of a first metal, and an overlay including a second metal that covers the base so as to constitute at least a part of the outer peripheral surface. The overlay is formed with a metallic structure that is continuous in the circumferential direction so as to connect between adjacent ones of the projections.
