PROBLEM TO BE SOLVED: To provide a movement guiding device which reduces a cost by simplifying a configuration of components, and also is inexpensive by providing an endless circulation path having a required number of rows according to guiding conditions. SOLUTION: In the movement guiding device 60, a movable member 15 freely moves relative to a raceway track member 11. The movable member 15 is composed of a first member 21 which has first track grooves formed so as to compose raceway surfaces for loaded rolling elements and almost halves of no-load raceway tracks, a second member 22 which has second track grooves formed so as to compose raceway surfaces of loaded rolling elements and almost halves of no-load raceway tracks, and one or more intermediate members 51 which are arranged between the first member 21 and the second member 22, and have first intermediate track grooves composing the raceway surfaces of loaded rolling elements and almost halves of the no-load raceway tracks formed on the side in the first member 21, and a second intermediate track grooves composing the raceway surfaces of loaded rolling elements and almost halves of the no-load raceway tracks formed on the side in the second member 22.
