PROBLEM TO BE SOLVED: To fit and correctly position an outer side roller to an inner side roller by simple work without exerting a bad influence in strength upon the inner side roller. SOLUTION: This guide roller is divided into an inner side roller 44 and plural outer side rollers 48A and 48B, and the outer peripheral surface of the roller 44 is formed of a projection such as a collar part 46, etc., integrally with the outer peripheral surface of the inner side roller 44, moreover the inner peripheral surfaces of the rollers 48A and 48B are provided with recesses such as peripheral groove 52, etc., thereto the projection is fittably insertable with a gap in an axial direction. The side surface of the projection is made to abut on any one side of the axial directional end surfaces of the recesses, consequently the rollers 48A and 48B can be positioned in the axial direction to the roller 44. |
