Abstract

PURPOSE: To prevent the deformation and defect of a tape eddge or the unstability of running, by means of moulding in one body of the hub and flange which is set up from the hub's base surface by a polybutylene terephthalate resin.
CONSTITUTION: A hub 1 and at least a lower flange 2 which is set up from the base surface are moulded in one body by a polybutylene terephthalate resin. An upper flange 3 is fixed by means of ultrasonic bonding etc. This polybutylene terephthalate resin have the polymerisation degree of the relative index 1.35W1.75 extent, and the third component such as an isophthalic acid etc. can be polymerized in a % range of 20% Mol. By such mean, the excellent running stability can be obtained than the use of the conventional polyacetal, and owing to its surface smoothness and low friction index, the fact that the sliding tape undergoes a bad influence, is reduced.
