Claims

[Scope of utility model registration request]

A roller conveyor of a type that conveys a plurality of plate-like objects in parallel, with flat parts on both sides of the plate-like object having a protrusion in the center sandwiched between upper and lower rollers, and the protrusion accommodated in the groove of the upper roller. In the apparatus, a common shaft on which each of the upper rollers is loosely fitted is supported via a pair of upper and lower spacer wheels on both sides of the lower roller integrally molded in a cylindrical shape, and the spacer wheels support a common shaft on which the upper rollers are loosely fitted. The distance between the common shaft and the lower roller is set so that a predetermined clearance can be formed between the upper and lower rollers, and the outer diameter of the upper roller is set at at least two points in the center of the common shaft. A roller conveyor device for plate-shaped objects, characterized in that an idle wheel having an approximately equal outer diameter is provided, and both sides of the groove portion of the upper roller are formed in a tapered shape that widens toward the other end.
