Abstract
A method for manufacturing a one-piece wheel by forging includes: producing an integral forging comprising: a disc portion, a rim portion, and an annular protrusion protruding from one side of the disc portion in a forging method; producing an outer bend by bending the annular protrusion through a flow-forming process; and forming a hollow portion by welding one end of the outer bend to one side of the rim portion.
