Abstract: A hollow rack bar (10) and a method of manufacturing the hollow rack bar are provided. The hollow rack bar (10) includes a hollow blank pipe portion having a uniform wall thickness, and a rack toothed portion. The rack toothed portion includes teeth, a flat portion (33) having a flat surface (35) and arranged side by side with the teeth in a direction along a center axis of the blank pipe portion, and a slanted portion (34) provided at an end of the flat portion (33) with respect to a direction perpendicular to the center axis and arranged to be lower than the flat portion. A length (t1) of the slanted portion (34) projected on a straight line perpendicular to the center axis and parallel to the surface of the flat portion is longer than zero and equal to or shorter than the wall thickness (t) of the blank pipe portion.
