摘要：
The top portion of a material for a rail of a linear guide is formed in a convex shape. In this convex shape, portions protruding to the side of a top surface are removed beforehand by rolling raceway grooves in side portions of a member of rectangular section, the top surface of which is flat. A rail made from this material by rolling raceway grooves in side portions have a flat top surface.
