Abstract: PURPOSE: To provide a safe moving walk by supporting at least either of opposed first and second rollers movably in the vertical direction in a moving walk in which two first and second rollers are arranged in the longitudinal direction even if a module is small. CONSTITUTION: A rotating shaft 16 of a small diameter roller 15' is eccentric, both ends of it are supported rotatably on a bearing 17, and the small diameter roller 15' is also supported rotatably on the rotating shaft 16.

On the other hand, when the small diameter roller 15' is a feeder, the rotating shaft 16 may be rotated in the direction over the small diameter roller 15 for the mating receiver. By this, a height difference between the small diameter roller 15' and the small diameter roller 15 can be adjusted so that it is smaller as the speed is higher and larger as it is lower. Thus, because the length of a module 2 is set so that it cannot be stepped over, a safe moving walk can be provided.
