PURPOSE:To make molding time shorter extremely, and improve the productivity by moving in an axial direction as required while pouring liquid fast thermosetting resin onto a rotating shaft. CONSTITUTION:After applying a mold releasing agent on a shaft 1, while the shaft 1 is being supported by the center of a rotating unit and chuck 3 and rotated therebetween, liquid fast thermosetting resin 5 comprising polyurethane material is spouted from a resin discharging port 4 onto the shaft 1, and the resin discharging port 4 is moved to an axial direction (arrow direction). Whereby the thermosetting resin starts to harden promptly without dripping, and the resin being about to harden on the shaft 1 and liquid resin poured anew are successively fused mutually in an axial direction, thereby forming an almost circular cross-sectional resin layer 6. |
