PROBLEM TO BE SOLVED: To inexpensively provide a moving guide member provided with a horizontal wheel, capable of ensuring smooth opening and closing operations of a moving door leaf while attaining both easiness of attachment and stability of attachment. SOLUTION: The moving guide member 1 comprises the horizontal wheel 5 and a regulating protruding part 4 provided on a guide body 2. The horizontal wheel 5 includes an axle matched to the flange space bisector L of a guide rail 8 and an elastic tire having a radial maximum deformation quantityΔR which is mounted thereon, and the outside diameter of the tire is set equal to the width of the guide rail 8. The regulating protruding part 4 has a symmetric shape across the flange space bisector L of the guide rail 8, and the width of the regulating protruding part 4 is set smaller than the outside diameter of the tire and larger than the length obtained by subtracting twice the maximum deformation quantityΔR of the tire from the outside diameter of the tire. When a load is applied to the moving door leaf 61, the regulating protruding part 4 is engaged with the guide rail 8 before the deformation of the tire reaches the maximum deformation quantityΔR.
