ABSTRACT:
The present invention provides a wheel and manufacturing method of the same which make it possible to prevent the formation of indentations along the hump parts in the inner circumferential surface of the rim. In a wheel which comprises a cylindrical rim consisting of a rolled metal plate, and in which hump parts that are used to lock the inner circumferential edge part of the tire are disposed circumferentially so that these hump parts protrude to the outside in the vicinity of the end part of the outer circumferential surface of the rim on at least the design surface side, the outer hump part is formed to have an increased thickness by damming so that this outer hump part protrudes outward while the inner circumferential surface of the rim that corresponds to the outer hump part is formed into a flat circumferential surface.
