<p><P>PROBLEM TO BE SOLVED: To provide a power transmission structure having high power transmission efficiency which transmits the power using grooves formed by drawing a roller body, and to provide a roller conveyor device. <P>SOLUTION: The roller conveyor device 7 includes rollers 2 with built-in motors and idle rollers 3, which are mixedly fitted to a frame 5 in parallel. Belts 1 are extended between the rollers 2 with the built-in motors and the adjoining idle rollers 3 on both sides thereof. The idle rollers 3 are rotated receiving the rotational force of the rollers 2 with the built-in motors. Each of the belts 1 has a connecting part 12 connecting two projecting part 10 and 11 with each other, each of which project to form an arc shape. The radius R of the arc configuring a lower face of the connecting part 12 is 20% larger than a radius r of the arc of the projecting part 10. The distance W between central axes X of the projecting parts 10 is twice as long as the full height H of the belt 1. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
