Abstract: PROBLEM TO BE SOLVED: To provide the guide roller which can securely guide a magnetic tape while maintaining economic and excellent travel stability of a magnetic tape. SOLUTION: A main guide roller 60 is equipped with a fixed shaft 62 and a cylindrical guide roller main body 64 which allows the fixed shaft 62 to penetrate it as a rotary shaft and rotates around the fixed shaft 62, and guides a magnetic tape in slide contact with the cylindrical surface of the guide roller main body 64. The fixed shaft 62 has an upper flange 66 pressed in and fixed to the upper end and a lower flange 68 through the guide roller main body, and consequently the guide roller main body 60 is prevented from moving up and down. When the guide roller main body 60 rotates around the fixed shaft 62, the guide roller main body 60 and fixed shaft 62 are in linear contact with each other. The guide roller main body 60 is a member which is formed of super macromolecular weight polyethylene and molded as a molding of super macromolecular weight polyethylene as a thick cylindrical body and then cut to a specific size.
