PROBLEM TO BE SOLVED: To provide a running frame device being light in weight, safe, inexpensive, suitable for mass production, and optimum for a curved conveyance part, having a simple configuration, and capable of deforming a frame member into a desired curved condition simply, securely, and accurately, being handled easily, having high machining precision and high rigidity, reducing cost, and facilitating assembly. SOLUTION: This running frame device is provided with at least a pair of frame members A1, a connection block 10, and a running rail D. The frame member A1 is formed into a substantially groove shape by a substrate 1 and a pair of bending plates 2, 4, and a plurality of cutout grooves 5 crossing substantially orthogonally the longitudinal direction are provided at an appropriate interval in the bending plates 2, 4. When the substrate 1 is curved in the direction of its thickness, a shape of the cutout groove 5 is deformed, and the bending plates 2, 4 are curved in the direction of its width.
