PROBLEM TO BE SOLVED: To ensure the safety circulation of a rolling element, by comprising an edge face forming part of a direction switching passage inner periphery guide part integrally molded with a movable body, and an end plate of a direction switching path outer periphery guide part separately molded, and depositing the joint faces of the periphery parts of the direction switching passage inner periphery guide part and outer periphery guide part. SOLUTION: A direction switching passage component 10 comprises a resin edge face forming part 11 comprising a direction switching passage inner periphery guide part 9a integrally molded with a movable block body 6, and a resin end plate 12 comprising a direction switching passage outer periphery guide part 9b separately molded. And the joint faces of the periphery parts of the inner periphery guide part 9a and the outer periphery guide part 9b are deposited, to form the direction switching passage 9 bendable into U-shape. So that the switching of the direction of a rolling element can be smoothly performed by straightening the deformation of the outer periphery guide part 9b by following the inner periphery guide part 9a of high accuracy, even when the end plate 12 is deformed.
