PROBLEM TO BE SOLVED: To provide a roller guide device offering a simple construction and an easy adjustment which is capable of preventing any rattling of a moving body for a shutter or the like having a movable shaft center. SOLUTION: Freely rotatable rollers 21 are installed to moving bodies 15, 16. The moving bodies 15, 16 can be moved by guiding them along guide rails 13 in the roller 21 guide device 100. A roller 21 is extrapolated in a swivel manner to an outer peripheral circle; bolts inserted to inner through holes in axis direction are penetrated through the moving bodies 15, 16 and tightened with nuts thereby making the device 100 being equipped with cylindrical roller supporting collars which are fixed to or made releasable from the moving bodies 15, 16; and the center of the outer peripheral circleof the roller supporting collars is decentered from the center of the through hole.
