PROBLEM TO BE SOLVED: To provide a roller conveyor device capable of reducing the number of components, easily performing the manufacturing and mounting works, and reducing the size thereof. SOLUTION: A storage case 13 for storing a roller unit 12 comprises a body case 31, and first and second mounting frames 32, 33 joined with right and left sides thereof. A guide groove 35 is formed between tips of clamp plates 32c, 33c of the mounting frames 32, 33. Plate insertion spaces R1, R1 are formed between a bottom plate 31a of the body case 31 and the clamp plates 32c, 33c. A lower face of a swollen part 42a of an upper clamp plate 42 is connected to a welded part 43 in a substantially center part of the upper surface of the lower clamp plate 41a of a metal piece body 41 to constitute a hooking metal piece 14. First and second clamp grooves g1, g2 with the clamp plates 32c, 33c inserted therein are formed between the upper surface of the lower clamp plate 41a and the lower surfaces of first and second clamp plates 42b, 42c on the right and left sides of the upper clamp plate 42.
