<p>PURPOSE:To provide a conveying roller having a good accuracy in its outside diameter, and also a high frictional coefficient, and to enable an article to be conveyed such as a conveying belt to be conveyed without causing unenenness in the conveying speed. CONSTITUTION:In a conveying roller 1 provided with a plurality of fine dotted rejections 12 on its outer circumferential surface, each of the dotted projections 12 is formed in an elliptical shape or a long circular shape long in the direction of the rotating center axis, so that the gripping force in the conveying direction can be increased.</p> |
