PROBLEM TO BE SOLVED: To provide a roller guide device which is excellent in elimination performance of deformation caused by assembling error and external force. SOLUTION: Upper and lower barrel-shaped roller lines 9, 10 each composed of a number of barrel-shaped rollers 8 rotatably arranged in a longitudinal direction of a raceway rail 3 are arranged between opposed surfaces of recessions 2 of bilateral side surfaces of the raceway rail 3 and projections 5 of bilateral dropping portions of a moving block 7. The upper and lower barrel-shaped roller lines 9, 10 can be slid along an inner peripheral arcuate surface 2a of the arcuate recession 2 of the raceway rail 3.
