PROBLEM TO BE SOLVED: To provide a moving structure including a spherical rolling support having a means capable of remarkably reducing friction resistance in joining surfaces between moving members. SOLUTION: The spherical rolling support 100 formed of ball elements is interposed between a plate-like member 300 and a member 400. The spherical rolling support 100 has contact structure of a large ball 5 and small balls 6 with a spherical surface, and as a result, can remarkably reduce friction force between the members.
