ABSTRACT:
A combined chain wheel and chain guard assembly is constructed from a single piece plate member which is formed, by stamping or the like, into a hub portion, two radially spaced annular members substantially lying in the same plane as the hub portion, an outermost rim member which serve as a chain guard radially spaced from the annular members and offset to the plane of the annular members, and radial strip members interconnecting the annular members and the outermost rim member. The perimeters of the annular members are flanged and toothed, and the toothed flange of the inner one of the annular members is arranged to be in a plane offset to the plane of the hub. The hub portion lies substantially in a plane of symmetry of the construction.
