The invention provides a direction control device, a casing pipe conveying device and method and a concentricity measuring device, which enable work pieces to face a specified direction quickly. The direction control device (20) comprises a direction judging part (29) which judges the direction of a casing pipe (F) with a front end portion (F2) and a rear end portion (F3), and a casing pipe moving part (26) which retains the casing pipe (F) by using a retaining part (26a) and enables the casing pipe (F) to move toward either a first discharge opening (24) or a second discharge opening (25) according to the judging result of the direction judging part (29). The retaining part (26a) is formed in the up-down direction (L1).
