Abstract
A tape guide roller for a tape cassette comprises an inner cylindrical body including a flange portion projecting from the outer circumference on one end thereof, and a synthetic resin injection portion provided at the outer circumferential surface at the other end thereof, the inner cylindrical body being molded by injecting synthetic resin from a direction substantially perpendicular to the axial direction thereof and an outer cylindrical body having an inside diameter such that it fits tightly over the inner cylindrical body, and includes a synthetic resin injection portion provided at the outer circumferential surface on the end side thereof opposite to the end side which serves as the insertion end for the inner side cylindrical body. The outer cylindrical body is molded by injecting synthetic resin from a direction substantially perpendicular to its axial direction through the synthetic resin injection portion. The outer cylindrical body is inserted from its insertion end onto the inner cylindrical body so that the former becomes integral with the latter, thus comprising a tape guide roller. The inner cylindrical body and the outer cylindrical body may also be molded by a double molding method.
