A method of producing a roller (1) to which a tire (13,15) is mounted so as to prevent racing comprises arranging a bearing (4,5,6) having one or a plurality of grooves (8) recessed on an outer peripheral surface of an outer race (4) with providing a gap (14) on a concentric circle inside a soft synthetic resin tire outer peripheral portion (13). Next a hard synthetic resin having a melting point higher than that of the soft synthetic resin in the tire outer peripheral portion is poured and charged into the gap formed between the tire outer peripheral portion and the outer race of the bearing so as to form the tire base portion (15). Thereby the tire base portion is integrally welded to the bearing and the tire outer peripheral portion. <IMAGE> |
