The outer peripheral surface () is convex outward in a radial direction of the roller main body (). The outer peripheral surface () has a first outer peripheral surface () and a second outer peripheral surface (). The first outer peripheral surface () has an arcuate shape formed to have the same radius of curvature on both sides of a maximum outer diameter point (A). The second outer peripheral surface () is further receded inward in the radial direction than an imaginary circle running along the first outer peripheral surface ().
