To provide a roller conveyor facility capable of maintaining an arrangement attitude without deflecting a cover body, by stably, easily and quickly performing attaching-detaching operation of the cover body.
A roller 10 is idly rotatably arranged in a plurality of places in the direction of a carrying passage 8 between a pair of right-left conveyor frames 3, and a rotational driving shaft 20 running along the carrying passage direction is arranged under a roller group. The rotational driving shaft and at least a partial roller are interlocked and connected via an endless rotary body 25, and a rotational driving part 30 is arranged to be interlocked with and connected to the rotational driving shaft. A cross-sectional recessed nondeflective cover body 40 is arranged for covering the rotational driving shaft from below. A pair of right-left engagement holders 47A and 47B freely engaging with right-left edge parts 41A and 41B being an upper position of the nondeflective cover body, are arranged on the conveyor frame side, and at least one engagement holder is displaceably constituted in the lateral direction. The attaching-detaching operation by supporting the nondeflective cover body, can be stably, easily and quickly performed since the nondeflective cover body does not deflect.
