PURPOSE:To reduce greatly the processing cost by constituting a tape guide having a flange by inserting under pressure a cylindrical member having a flange to the inside of the opening end part of a cylindrical member having an outer circumferential surface which is in contact with a tape. CONSTITUTION:A tape guide 11 is provided with a nut 13 having a tape which engages a screw part cut at the upper part of the outer circumference of a shaft 12 set on a chassis 1, the 2nd cylindrical member 15 having a flange 14 projected over the outer circumferential surface of the nut 13, and another cylindrical member 16 having an outer circumferential surface 4 having contact with a tape which is inserted under pressure. Therefore a tape guide is formed by inserting under pressure both the nut 13 and the member 15. Thus the surface 4 can be easily polished, and therefore the processing cost can be greatly reduced. |
