To provide a highly reliable resin pulley having high dimensional accuracy with no occurrence of distortion due to shrinkage after molding and improved rotating accuracy with no occurrence of vibration.
The resin pulley 6 is integrally provided on an outer diameter face 2a of a rolling bearing 5. It is formed of a polyamide resin composition which mainly contains copolymer nylon and which is reinforced by adding glass fibers, wherein the orientation of the glass fibers in a molten resin composition is properly moderated to reduce a difference in molding shrinkage (%) between a flowing direction and a flow perpendicular direction. Thus, it maintains such high tensile strength, bending strength and compression strength as in a normally glass fiber reinforced nylon resin.
